Description

pliers

The utility model relates to a hand tool, in particular to a pliers which are easy to use but simple in structure.

As shown in Fig. 7 to Fig. 8, it is the existing pliers, which has a first handle 71, and one end of the first handle 71 has a chute 72, and the two side walls of the chute 72 respectively have a plurality of Opposite to the tooth portion 73, the other end of the chute 72 has a fixed jaw 74 bent at an angle. The first handle 71 is pivotally connected to a second handle 75 , and one end of the second handle 75 has a pivot 76 pivotally arranged on the chute 72 , the pivot 76 can just be moved by the teeth of the chute 72 . 73 , one side of the pivot 76 has a cut surface 77 , and the end of the pivot 76 away from the second handle 75 has a movable jaw 78 . When in use, it is necessary to open the first handle 71 and the second handle 75 to the maximum width shown in FIG. The width of the opening is to match the width of the clamped object (not shown in the figure), but it is quite troublesome to open, move the position of the pivot rod 76, and clamp in such an operation process.

The main purpose of this utility model is to provide a kind of pliers in order to solve the above-mentioned problems existing in conventional pliers, by applying force to the handle and the pressure handle of the main body, the clamping rod is shifted, and the sliding rod is slid The groove limits the direction of movement, so that the movable jaw and the fixed jaw can be clamped without pitch, so as to increase the convenience of use.

The second purpose of the utility model is to provide a pliers with simple structure.

The purpose of this utility model is achieved by the following technical solutions.

The utility model provides a pair of pliers, which includes: a main body, which has a pressure handle, the top of the pressure handle is integrally connected to the front bottom end of a connecting section, the connecting section has a sliding groove, the sliding groove One end is higher and the other end is lower. The top end of the connecting section has a fixed jaw; a handle, the top end of which is pivotally arranged at the rear side of the connecting section, and the middle section of the handle has a pivot hole; an elastic The element is used to separate the pressing handle of the main body from the handle; a clamping rod, the bottom end of which is pivotally arranged in the pivot hole of the handle, and a sliding rod is provided in the middle of the clamping rod, and the sliding rod It is installed in the sliding groove, and the top end of the clamping rod has a movable jaw.

The purpose of this utility model can also be further realized by the following technical measures.

The aforementioned pliers, the elastic element is a compression spring, one end of the spring is fixed on a fixed rod at the rear bottom edge position of the connecting section away from the pressure handle, and the other end of the spring is against the handle at the position close to the upper edge. in a groove.

For the aforementioned pliers, the front side wall of the slide groove is provided with a plurality of longitudinally arranged teeth, and the teeth cooperate with the slide rod.

In the aforementioned pliers, the slide groove is in the shape of an arc.

In the aforementioned pliers, the elastic element is a torsion spring, one end of the torsion spring is against the connecting section, and the other end is against the handle. The elastic element can also be a compression spring, one end of the compression spring is connected to the middle position of the pressure handle, and the other end of the compression spring is connected to the middle position of the handle.

Concrete structure of the present utility model is provided in detail by following embodiment and accompanying drawing thereof.

Figure 7 is a side view of conventional pliers.

Fig. 8 is a schematic diagram of the use state of conventional pliers.

Please refer to Fig. 1 to Fig. 4, the utility model comprises: a main body 1, it has a pressing handle 11, and the top end of this pressing handle 11 is integrally connected with the front side bottom end of a connecting section 12, and this connecting section 12 has a Through the sliding groove 13, one end of the sliding groove 13 is higher, while the other end is lower. The connecting section 12 is provided with a fixed rod 14 at the rear bottom edge of the pressure handle 11, and the fixed rod 14 is used to fix a compression spring 15, the top end of the connecting section 12 has a fixed jaw 16.

A handle 2, the top of which is pivotally arranged at the rear side of the connecting section 12, the handle 2 has a groove 22 near the upper edge, the groove 22 can be against the other end of the spring 15, the There is a pivot hole 21 at the middle section of the handle 2 .

A clamping rod 3 is composed of two pieces. The bottom end of the clamping rod 3 is pivotally arranged in the pivot hole 21 of the handle 2. There is a sliding rod 31 in the middle of the clamping rod 3. The sliding rod 31 is worn Located in the sliding slot 13 , the top end of the clamping rod 3 has a movable jaw 32 .

As shown in Figures 3 to 4, when the utility model is used, force is directly applied to the pressure handle 11 and the handle 2, and the handle 2 starts to deflect, and the compression spring 15 is also affected by the distance between the fixed rod 14 and the groove 22. becomes smaller and compressed, the handle 2 drives the pivoted clamping rod 3 to move, and the sliding rod 31 of the clamping rod 3 is restricted by the sliding groove 13 in the moving direction, and can only move to the higher end of the sliding groove 13. At the same time, the The movable jaw 32 moves toward the fixed jaw 16. When the movable jaw 32 touches the object W to be clamped, the sliding rod 31 abuts against the side wall of the sliding groove 13, and the side wall of the sliding groove 13 forms a barrier. On the surface, the sliding rod 31 forms a fulcrum, the user continues to apply force to clamp the clamped object W; and the user relaxes the force, the handle 2 can be rebounded by the restoring force of the spring 15, the grip The handle 2 also pulls the clamping rod 3 down, so that the openings of the movable jaw 32 and the fixed jaw 16 are widened, and the clamped object W can be released.

From the above, it can be seen that the utility model only has the main body 1, the handle 2, and the clamping rod 3 in structure to achieve the predetermined effect. Therefore, the structure is much simpler than the conventional pliers that can automatically adjust the distance between the two jaws. And in use, since the sliding groove 13 does not have any teeth, so within the maximum opening width of the movable jaw 32 and the fixed jaw 16, the sliding rod 31 can be moved to any position, so that the movable jaw 32 and the fixed jaw 16 are clamped. Tighten the clamped object W to achieve the purpose of no-pitch clamping, and also increase the convenience of use.

Of course, there are still many examples of the present invention, between which only the details vary. Please refer to Fig. 5, the second embodiment of the present utility model is that the front side wall of the sliding groove 41 is provided with a plurality of longitudinally arranged teeth 42, and the connecting section 43 and the pivotal position of the handle 44 are provided with a A torsion spring 45, one end of the torsion spring 45 is against the connecting section 43, and the other end is against the handle 44. When clamping, the plurality of teeth 42 can increase the positioning effect of the sliding rod 46, and also increase the clamping effect. Effect.

Please refer to Fig. 6, the third embodiment of the present utility model is that the sliding groove 51 is set as an arc shape, and the middle position of the pressure handle 52 is connected to one end of a compression spring 53, and the other end of the compression spring 53 One end is connected to the middle position of the handle 54, and the sliding groove 51 is to drive the moving state of the sliding rod 55 when the handle 54 is deflected, so that the clamping of objects is smoother.
