Detailed Description

The following description is presented to disclose the application and to enable any person skilled in the art to practice the application. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The underlying principles of the application, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other technical solutions without departing from the spirit and scope of the application.

The screwdriver is used for unscrewing screws on devices and is widely applied to the aspects of life and production of people, and the existing screwdriver has no moment arm except for a handle, so that only the wrist can be used for applying force when the screwdriver is screwed, and the situation that the screwdriver is very laborious when the screwdriver is screwed is caused. At present, in order to save labor when a screwdriver is rotated, a user needs to additionally prepare a metal rod capable of being inserted into a screwdriver handle hole by himself to form a force arm, and the situation that a proper metal rod cannot be found exists, so that the effect of saving labor cannot be achieved in the actual use process.

Based on the above reason, this application has solved and has realized that the screwdriver can be laborsaving, need not look for suitable metal pole simultaneously and be connected the problem in order to form the arm of force with the screwdriver.

In order to solve the existing problems, the application provides that the screwdriver handle is directly integrated with the screwing component which can be popped up and turned over to form the force arm so as to solve the problem that the existing screwdriver is labor-consuming in the actual use process.

The screwdriver of the present application is explained in detail below by way of the following examples:

referring to fig. 1 to 6, the labor-saving screwdriver of the present application includes a handle 10, a main rod 20, a replaceable screwdriver bit 30 and a force arm assembly 40, wherein the handle 10 is made of a high-strength plastic material, and a plurality of anti-slip surfaces 11 with arc-shaped inner walls are disposed on the handle 10, and the anti-slip surfaces 11 can be attached to fingers of an operator to achieve an anti-slip effect when the screwdriver is rotated. The main rod 20 is a metal rod with a hexagonal section, and the main rod 20 can be made of one of stainless steel, high-carbon steel and aluminum alloy materials.

The upper end of the main rod 20 is fixed to the lower end position of the handle 10, and the lower end position of the main rod 20 is provided with a sleeve part 21, and the sleeve part 21 is used for inserting the screwdriver head 30 into the main rod 20, so that the screwdriver head 30 can be replaced. The inner wall of the socket part 21 is a hexagonal cavity, one end of the corresponding screwdriver bit 30 is provided with an insertion part 31 which can be inserted into the socket part 21, and the cross section of the insertion part 31 is hexagonal which is matched with the cross section of the socket part 21. The screwdriver bit 30 can be inserted into the socket part 21, and the screwdriver bit 30 is attracted by the strong magnetic magnet 22 in the socket part 21; wherein the screwdriver head 30 is in various shapes such as a straight line, a cross, a Chinese character 'mi', a star (computer), a square head, a hexagonal head, a Y-shaped and the like.

Specifically, a cylindrical accommodating cavity 12 is formed in the handle 10, and the moment arm assembly 40 is hidden in the accommodating cavity 12. And the arm assembly 40 can be withdrawn from the container 12 and rotated 90 degrees to the left or right to form the arm 42, although it can be rotated to a lesser or greater degree, preferably 60-120 degrees.

Specifically, the moment arm assembly 40 is in rotation-stopping connection with the handle 10; arm of force subassembly 40 includes joint 41 and arm of force 42, and the inner wall of holding chamber 12 is outside protrusion partially, and the shape of face that forms a plurality of outer walls is the column 121 that splines of arcwall face, joint 41 is located holding chamber 12, and this joint 41 can slide along the length direction of holding chamber 12 to the realization can be with the joint 41 in the holding chamber 12 can be pulled out to the position department that is close to holding chamber 12 export by holding chamber 12 bottom. The specific joint 41 can only reach the position close to the outlet of the accommodating cavity 12, and because the position close to the outlet of the accommodating cavity 12 is integrated with a limiting ring 122 with an inner diameter smaller than that of the accommodating cavity, the limiting ring 122 is fixedly connected to the inner wall of the upper end of the accommodating cavity 12 through glue. The joint 41 is provided with a plurality of rotation stopping openings 411, and the shape of the rotation stopping openings 411 is matched with the rotation stopping columns 121 in the accommodating cavity 12, so that rotation stopping connection between the joint 41 and the handle 10 is realized.

The joint 41 is of a structure with a large upper part and a small lower part, and one end of the force arm 42 is rotationally connected with the upper end of the joint 41 through a metal column; the force arm 42 may be a single metal rod. Of course, the arm 42 can also be formed by two metal rods as shown in the present example, which form the structure of a telescopic rod. Specifically, arm 42 specifically includes body 421, body of rod 422 and elastic component 423, wherein body 421 is the tubular metal resonator, body of rod 422 inserts inside body 421, and body of rod 422 is when pulling out, and its tip can not throw off from body 421 in the middle of, and elastic component 423 is located inside body 421, and this elastic component 423 is the spring, and the one end of elastic component 423 supports the bottom of body 421, and the other end supports the one end at body of rod 422.

A sealing cap 123 is connected to the handle 10 through a screw thread, the sealing cap 123 is specifically connected to the limiting ring 122 through a screw thread, and the sealing cap 123 is covered on the handle 10 so as to hide the moment arm assembly 40 in the accommodating cavity 12. Specifically, in the operation process, the sealing cover 123 can be turned and unscrewed, and the rod 422 is ejected out by the spring, so that an operator can conveniently pull the rod 422, the rod 422 and the pipe 421 are pulled out from the accommodating cavity 12 until the joint 41 is located at an outlet position close to the accommodating cavity 12, and then the force arm 42 is turned over, so that an included angle of ninety degrees is formed between the force arm 42 and the main rod 20.

In order to ensure the stability of the screwdriver when the screwdriver is used for screwing the screw and avoid injury caused by friction to a user, a rotating sleeve 50 is sleeved at the lower part of the handle 10 of the screwdriver, and the rotating sleeve 50 is used for corresponding to the jaw of the hand of the user, so that the rotating sleeve 50 can be buckled by a forefinger and a thumb when the screwdriver is used, the rotating sleeve cannot rotate when the screwdriver rotates, and the screwdriver is more convenient to use. Specifically, the rotating sleeve 50 is connected to the handle 10 by a plurality of rollers 55, thereby ensuring smooth rotation of the handle 10 relative to the rotating sleeve 50.

Meanwhile, the surface of the rotating sleeve 50 is roughly arranged, and the rough arrangement can guarantee the stability of the hand when the rotating sleeve is buckled.
