Embodiment 1

[0023] see Figure 1-3 As shown, this embodiment is a hand-held torque gun buffer labor protection device, including a cushion cover 1, the cushion cover 1 has a columnar structure as a whole, and bumps 2 are evenly distributed on the inner wall; the diameter of the pipe body in the middle of the cushion cover 1 is Slightly larger than the diameter of the middle part of the shell of the torque gun 4, the two ends of the cushion cover 1 shrink inward to form a narrow mouth 3 for preventing the upper and lower positions of the torque gun 4 from changing. The bump has a columnar structure, and the thickness of the bump is 0.5 mm. Cushion pad cover 1, convex point 2 and narrow mouth part 3 are integrally constructed. Considering that the internal convex point of the cushion pad cover 1 needs a certain amount of elastic deformation, as well as the user's hand feeling, the choice of rubber hardness needs to be moderate. Under the premise of durable use of the cushion cover 1, the r...

Embodiment 2

[0027] The structure and application of this embodiment are basically the same as those of Embodiment 1, the difference is that the bumps are in a columnar structure, and the thickness of the bumps is 2 mm.

Embodiment 3

[0029] The structure and application of this embodiment are basically the same as those of Embodiment 1, except that the bumps are in a columnar structure, and the thickness of the bumps is 1 mm. This embodiment is the preferred embodiment of the invention.

Abstract

The invention discloses a handheld torque gun buffering labor protection tool. The handheld torque gun buffering labor protection tool comprises a buffering cushion sleeve integrally of a columnar structure. Protruding points are evenly distributed on the inner wall. The protruding points in the buffering cushion sleeve in the rotation direction rub with a torque gun shell so that elastic deformation can happen for digesting part of impulse directly acting on the hand from the torque gun. The two ends of the buffering cushion sleeve are contracted inwards to form narrow opening parts used for stopping changes of the up-down position of the buffering cushion sleeve and the torque gun, and the buffering cushion sleeve, the protruding points and the narrow opening parts are of an integrated structure. The standard design is adopted in the provided handheld torque gun buffering labor protection tool, batched production can be better achieved with low cost, hurt to the user bodies from the tool can be reduced, the morbidity probability of occupational diseases of the wrist parts of workers is reduced, the comfort degree of the production tool is improved, and the enterprise culture of people first is embodied.

Description

technical field [0001] The invention relates to the technical field of electric torque wrench accessories, in particular to a hand-held torque gun buffer labor protection appliance. Background technique [0002] A large number of screws and bolts are used in the assembly and production of various industries. There are many kinds of screw and bolt assembly tools, and one of the more common semi-automatic assembly tools is the torque gun. When the torque gun is working, it completes a process from acceleration to constant speed and then to deceleration. The most obvious force felt by the operator in this process is in the stage of rapid deceleration. In order to overcome the instantaneous impulse generated by the sudden stop of the torque gun, the operator's wrist and screws will provide a resistance to ensure the smooth assembly of the torque gun. In the case of a heavy workload during the peak production period, the above operations will cause the operator's wrist to be str...
