Description

clamp

【Technical field】

The utility model relates to a hand tool, in particular to a clamp, which can adapt to different use spaces and be used in different operation modes, and is more suitable for operation in narrow spaces.

【Background technique】

A general clamp includes a clamping part and a handle part. When the handle part is manipulated, the opening and closing of the clamping part can be controlled to clamp objects. The clamping part and the handle part of the existing clamp are arranged in a straight line, and the wrist is bent during use, which is easy to cause the so-called carpal tunnel syndrome (carpal tunnel syndrome) injury to the user, and is not conducive to narrow space or limited space in operation.

Recently, the advent of new type clamps, as disclosed in Taiwan Patent Publication No. 474238 (invention title: clamps suitable for narrow spaces), it mainly forms a pair of clamps at both ends of the handle portion of the clamps. L-shaped pivoting part, and a corresponding L-shaped pivoting part is formed on the clamping part of the clamp, and the handle part and the clamping part are pivoted through a pivot, so that the two become a rotatable sleeve However, the design of the pivoting part of this existing clamp is not ideal, because the pivoting parts of the handle part and the clamping part are all L-shaped, and the space between the L-shaped pivoting parts The contact surface has only one side, which is only suitable for providing one-way turning force. For the clamp that needs to rotate the object in the forward and reverse directions, the structural strength of the pivoting part is insufficient, and it is easy to cause damage.

【Content of utility model】

The main purpose of this utility model is to provide a clamp suitable for narrow spaces with high structural strength, which can be adjusted into different configurations to adapt to various narrow spaces.

In order to achieve the above object, the utility model adopts the following technical scheme: a pivoting part is added between the clamping part and the handle part of the clamp, and the pivoting part mainly uses a screw to connect a concave pivot groove and a convex The pivot block is combined to keep it in a rotatable state, and the pivot part is provided with a catch hole and a top catch member, which prevents the handle part or the clamping part from swaying arbitrarily.

Due to the adoption of the above-mentioned technical solution, the utility model has the following advantages: through the above-mentioned structure, the clamp can be transformed into an appropriate operation type to adapt to different operation spaces; The connection method enhances the structural strength of the pivoting part and prevents clamp failure. The utility model is a very practical and progressive invention, which is quite worthy of being promoted by the industry and made public to the general public.

【Detailed ways】

The utility model relates to a clamp, please refer to Fig. 1 to Fig. 3, the clamp 1 mainly includes a clamping part 10, a pivot part 20 and a handle part 30, wherein:

The clamping part 10 can be opened and closed to clamp the object, and the handle part 30 is for the user to hold and apply force. This is a structural feature of the general existing clamps and is not the key point of the present invention. Let me repeat.

The pivoting portion 20 includes a pair of concave pivot slots 21, a pair of convex pivot blocks 22, a pair of screw members 23, a pair of washers 24, and a pair of top catch members 25; the concave pivot slots 21 are formed on the clip One end of the solid part 10, and the left and right sides of the concave pivot groove 21 are provided with pivot holes 210, and a chamber 211 is formed on the bottom side of the concave pivot groove 21; the convex pivot piece 22 is slightly semi-cylindrical, In addition, a through hole 220 is formed in the axial direction of the convex pivot 22, and a plurality of locking holes 221 are formed in the radial direction of the convex pivot 22; the pushing member 25 is composed of an elastic member and a steel ball.

When the utility model is assembled, the top catch 25 is first placed in the chamber 211 of the concave pivot groove 21, and the gasket 24 is placed on the outer edge of the perforation 220 of the convex groove block; 22 is inserted into the concave pivot groove 21, so that the top catch member 25 and the locking hole 221 are engaged, and the gasket 24 is limited between the concave pivot block and the concave pivot groove 21; Insert the pivot hole 210 of the concave pivot groove 21 and the perforation 220 of the convex pivot block 22, and insert the washer 24 into the pivot hole 210, so that the pivot part 20 connects the clamping part 10 and the handle part 30 Pivot, and in a rotatable state, and the pivot part 20 of the clamp of the utility model is set with a convex pivot block 22 with a concave pivot groove 21, so that the best structural strength can be obtained, and the The structural strength of the pivoting portion 20 is not strong enough to cause the risk of failure.

Please refer to Fig. 4 to Fig. 6, through the design of the pivoting part 20 of the present invention, the clamping part 10 and the handle part 30 can be adjusted to different angles, and after the required angle is adjusted, the Appropriate locking force is provided through the locking hole 221 and the top locking member 25 to prevent the clamping part 10 and the handle part 30 from swaying randomly, causing unnecessary troubles to the user.

The utility model must particularly emphasize that the clamp of the utility model can make its overall structure more perfect, especially in the field where the development space of the scope of the tool body is quite limited, it is quite commendable, so the utility model Definitely meets the progressive requirements.

It can be seen from the above description that the tongs of the utility model can be transformed into different operating states to adapt to use in various narrow spaces and conform to ergonomic design.

The above-mentioned contents are only used to explain the preferred implementation of the present utility model, and are not intended to limit the utility model in any form accordingly. Changes should still be included in the intended protection category of the present utility model, wherein as shown in Figure 7, the screw member can also be replaced by a pivot (23') to bring into play normal functions, in addition, the concave pivot groove It can also be arranged on the handle part, and the convex pivot block is arranged on the clamping part.
