Description

The present invention relates to an auxiliary tool for a driver, and more specifically, the screwing member is held by being attached to the tip of a tool used for attaching / detaching the screwing member, and the screwing member is not dropped even with one hand without a fingertip support. It is detachable, and when it is pressed against the washer, etc., the holding part loses its gripping force because it spreads in the circumferential direction due to the inclined surface and slit arranged at a predetermined position, and on the other hand, when it is loosened, the axial direction by Subomu thing, it relates to an attachment type screwed member retainer having a function of exerting a gripping force.

  The driver is a function for engaging and disengaging the screwing member by rotating the shaft body by engaging the engaging portion at the tip of the shaft body with the engaging groove formed in the head of the screwing member. Depending on the shape of the groove, there are various types such as a Phillips screwdriver, a flat screwdriver, a positive drive screwdriver, a Torx (registered trademark) screwdriver, a hexagon screwdriver, a triangular screw screwdriver, and a square screwdriver.

  In particular, a Phillips screwdriver is a tool that has a high penetration rate so that it can be said that it is always included in tools that are always used in general households. The screw members used are flat screws, pan-head screws, bind screws, tapping screws, drill screws. It is a tool for fastening means that is used for attaching and detaching a wide variety of screwing members such as corded threads, and also used in a wide range of industries such as construction, machining, maintenance, repair, and so on.

  Thus, although it is the use condition of the screwing member of a screw and a driver which are prevailing widely, a big problem remains. For example, when working in a place where there is no space to hold the screwing member by hand, the screwing member cannot be held at the tip of the driver, so it is difficult to screw down and screw in the downward or sideways direction. It is. In addition, if the screwing member falls off in a narrow space, it may not be able to be taken out unless the entire apparatus is disassembled. In particular, the presence of foreign matter may cause fatal damage to the apparatus, and there are many cases where work is performed with great care.

  In view of such problems, various technical proposals have conventionally been made. For example, a method of making the engaging portion on the tip end side of the driver shaft body permanent magnet and holding the screwing member on the engaging portion by magnetic force has been proposed and is a known technique. (Patent Literature 1) However, the effect of the magnetic force is lost to gravity and the screwing member is displaced, the use in a device that dislikes the magnetic field, or the screwing member made of aluminum or stainless steel that does not have magnetism. There is a problem that it cannot be demonstrated.

  In addition, a method of attaching an attachment having a spring washer inside the attachment to the tip end side of the shaft body of the driver and holding the screwing member has been proposed and is a known technique. (Patent Document 2) However, this technique has a complicated attachment structure, and there is a problem that it is considered that the cost and the trouble of specification are complicated.

  Still further, a method for holding a screwing member, in which an attachment having a magnet is attached to the tip of the shaft of a driver, and the attachment has a locking groove inside, and can be used for a screwing member having no magnetism. Has been proposed and is a known technique. (Patent Document 3). However, in such a technique, when the screwing member is screwed, there is a problem that the tip of the attachment is sandwiched between the seating surface of the screwing member and the flat part to be screwed.

The present invention is a holder 10 for holding the screwing member B from the tip of the driver D without dropping off, and holds the screwing member B firmly with a simple structure to prevent problems due to dropping off. In order to perform the function, a locking groove 210 corresponding to the shape of the screw member B and an attachment / detachment mechanism 220 that is opened by the presence of the inclined surface 221 of the contact end portion and pressing when tightening are provided. It is the biggest feature. Hereinafter, description will be given based on the drawings.

Figure 1 is an overall configuration diagram of the attachment-type engagement member holder 1 according to the present invention. FIG. 2 is an explanatory view of the use state of the attachment type screwing member holder 1 according to the present invention, and FIG. 2 (a) shows the attachment type screwing member holder 1 , the screwing member and the driver according to the present invention. FIG. 2B shows a state before and after the attachment type screwing member holder 1 , the screwing member, and the driver are separated from each other. FIG. 3 is a cross-sectional view and a side view of the attachment-type screwing member holder 1 according to the present invention. FIG. 3 (a) shows a cross section in the axial direction, and FIG. The side view seen from the opening side of the tool attachment part 300, FIG.3 (c) has each shown the side view seen from the opening side of the attachment type screwing member holder 1. FIG.

As shown in FIG. 1, the attachment type screwing member holder 1 includes a holding part 200 and a tool attachment part 300. A material having an appropriate repulsive force when pressing the screwing member against the locking groove 210 and having an elastic characteristic that returns to the original state after separation is selected. For example, any of resin, silicone, nylon, or rubber, or a combination thereof may be used, but is not limited thereto. The dimensions are designed so that the maximum outer diameter is as small as possible with respect to the tip of the driver shaft. This is because, when the outer diameter is large, the workability is hindered in the work in a narrow place.

  The holding unit 200 includes a locking groove 210 for holding the screwing member, and an attaching / detaching mechanism 220 for releasing the screwing member from the locking groove 210, and is screwed as shown in FIG. The member is engaged with the locking groove 210, and in this state, is engaged with the tip of the driver.

The tool mounting portion 300 has a tool fixing function and a fixing hole 310, and the mounting state of the driver D on the shaft body portion is managed by the size of the tolerance here. Specifically, for example, it has a fixing hole 310 for exhibiting the tool fixing function to the conventional Phillips screwdriver D stable pressed here. The dimension has an appropriate length so that the shaft body of the driver D can be stably held and the driver D can be easily mounted. A plurality of slits 311 may be provided radially from the fixing hole 310. Furthermore, as shown in FIG. 4A, it is desirable to provide a tool fixing mechanism 320 so that it can be firmly fixed to the shaft of the driver D. FIG. 4 (c) shows a configuration in which a female screw is provided, and this is a method of fixing to this with a screwing member such as a screw bolt or a butterfly bolt. However, the present invention is not limited to this. For example, a taper screw is formed on the outer peripheral surface of the slit 311 portion of the tool mounting portion 300, and it is fastened and fixed like a collet chuck. It is desirable to press with a predetermined force using an elastic member. The simplest is to hold it by moderate tightening due to the dimensional tolerance of the fit.

  The locking groove 210 holds the screwing member by engaging with the screwing member. As shown in FIG. 3, the head of the screwing member can be held in various shapes.

  The attachment / detachment mechanism 220 includes an inclined surface 221 and a slit 222. When the inclined surface 221 at the tip comes into contact with a plane into which the screwing member is screwed, the attachment / detachment mechanism 220 is opened by pressing from the driver. Further, after the screw member is detached, the original shape is restored within the elastic limit by the pressure removal. With these functions, the screwing member can be accurately screwed up to the final tightening.

  The inclined surface 221 has a function of opening the attachment / detachment mechanism 220 in response to a pressure from a driver.

As shown in FIGS. 1 and 3, the slit 222 has a function of making the opening side of the holding part 200 easy to open by pressing or depressurization and to easily return to the original shape by elastic force. In FIG. 1, the slits 222 are provided at three places and in FIG. 4 (c) at four places. However, the number is not limited, and the slits 222 are suitably provided according to the elasticity of the material, the diameter, and the like.

  The tool mounting portion 300 is provided with a fixing hole 310 that penetrates in the axial direction to insert the driver D, and a slit 311 as shown in FIG. The dimension of the fixing hole 310 is an inner diameter that is in close contact with the shaft body of the driver D and is stabilized. Specifically, for example, in the case of a Phillips screwdriver, the shaft diameter of the driver D needs to correspond to three types of diameters (5 mm, 6 mm, and 8 mm) defined in the JIS standard.

Moreover, even if it is not the exclusive driver D but the existing driver D, in order to make it the attachment type which can attach the attachment type screwing member holder 1 which concerns on this invention to the axial part, in the tool attachment part 300, A tool fixing mechanism 320 is provided. The fixing force by the tool fixing mechanism 320 is not simply firmly fixed, but is a fixing force that allows the attachment-type screwing member holder 1 to be slid and moved by a fingertip, thereby gripping and releasing the screwing member B. In such a state, for example, the fixing driver D has a fixing force that allows the tip of the plus driver D to slide to a position where it is firmly inserted into the plus groove of the screwing member B, and pushes the opening side of the holding portion 200 by pressing. It is a fixing force within a range that can withstand the force and does not slide.

  The simplest structure of the tool fixing mechanism 320 is due to dimensional tolerances. If the inner diameter (dimensional tolerance) and length of the fixing hole 310 are determined in consideration of various conditions such as elastic force, friction, and dimensional tolerance of the material to be used so as to be within the range of the fixing force. Good. In addition to these methods, the number, depth, and length of the slits 311 are also considered. In addition, although eight slits 311 are provided on the drawing, such illustration is merely an example, and the number of slits is not limited thereto.

  As another mechanism, as shown in FIG. 3A, a structure in which one or more female screw portions are processed in the tool mounting portion 300 and then tightened and adjusted with a screw screw, a butterfly bolt, or the like is also structured. In terms of cost, it is simple, economical and effective.

Further, although not shown, as yet another mechanism, the split portion is provided in the tool mounting part 300, even chucking mechanism, such as a so-called collet chuck tightening the tapered over threaded or tapered over sleeve like chucking nuts good.

Next, the usage method of the attachment type screwing member holder 1 according to the present invention will be described with reference to FIGS. 4 and 5. 4 shows a state when the screwing member B is attached, and FIG. 5 shows a state when the screwing member B is removed. The present invention is applied to the present invention in a narrow place where the fitting portion of the screw member B is narrow and a fingertip does not enter, or in a place where the screw member B is not allowed to fall off due to the relationship with the device below. The use of the attachment type screwing member holder 1 is particularly effective.

First, the attachment type screwing member holder 1 according to the present invention is attached to the tip of the driver D to be used. At this time, it is temporarily installed near the tip of the driver D. Next, the screwing member B is pushed in from the opening side of the holding part 200 of the attachment type screwing member holder 1 to be inserted and hooked onto the locking groove 210 to be mounted. As shown in FIG. 4 (a), the screw member B mounted by inserting the tip of the driver D from this state to the position where the tip of the screwdriver D is firmly inserted into the plus groove or the Torx (registered trademark) groove of the screw member. The screw D is held at the tip of the driver D, and can be inserted with one hand by guiding the tip of the screwing member insertion B to the target female screw portion.

Next, when the screwing member B is tightened, the inclined surface 221 provided at the opening side end portion of the holding part 200 in contact with the female screw side surface causes the screwing member B to move as shown in FIG. Since the opening side end portion of the holding portion 200 that has gripped the lower neck is pushed apart in the circumferential direction and detached from the screwing member B, it can be pulled out as shown in FIG.

On the other hand, when removing the screwing member, the tip of the driver D is pressed against the plus groove or the like as shown in FIG. 5A, and the opening side end of the holding portion 200 is shown in FIG. 5B. The part is pushed and expanded in the circumferential direction, and the driver D is rotated in the direction in which the screw is loosened. As a result, a gap is formed between the female screw side surface and the neck of the screwing member B, and the opening side end of the holding part 200 returns to the axial direction by the elastic force of the material. The protruding head of the screwing member B can be gripped by 210 and can be removed without falling off as shown in FIG.

FIG. 6 is an explanatory diagram of a reference embodiment illustrating the types of screw members B to be used in the attachment type screw member holder 1 according to the present invention. FIG. 6A shows an example that can be implemented with a “pan head screw”, FIG. 6B with a “blade screw”, and FIG. 6C with a “bind screw”. However, this illustration does not indicate that the screws are limited to these screws, but indicates that the screws can be applied to the various shapes of screws described above.
