non-slip wrench

Abstract

The invention discloses an antiskid wrench. The antiskid wrench is characterized in that the antiskid wrench comprises a wrench body, a compression bar handle, a plunger and a pressing assembly; the wrench body is sequentially divided into a nut connecting part, a handle mounting part, a plunger part and a holding part from left to right; the nut connecting part is provided with a nut sleeve holepenetrating through the front and back of the nut connecting part; a sliding block mounting hole penetrating through the interior and exterior of the nut connecting part is formed in the upper part ofthe nut connecting part; a pressing sliding block of the pressing assembly is arranged in the sliding block mounting hole of the nut connecting part in a sliding manner; a handle mounting seat is arranged on the upper side of the handle mounting part; the compression bar handle is hinged with the handle mounting seat; the plunger part is provided with a plunger hole penetrating through the upperpart and lower part of the plunger part; the plunger is arranged in the plunger hole in a sealing and sliding manner; a first cavity in the wrench body penetrates through the nut connecting part, thehandle mounting part, the plunger hole of the plunger part and the holding part; liquid plastic is arranged in the first cavity; and the compression bar handle gest close to the holding part and presses the plunger downwards, and the liquid plastic is extruded by the plunger to allow the pressing sliding block to be contracted inward in the radial direction to clamp six surfaces of a nut.

Description

Technical field [0001] The invention relates to the technical field of mechanical assembly tools, in particular to a non-slip wrench which can effectively protect a nut and is not easy to slip. Background technique [0002] In industrial technology, a wrench is one of the most commonly used tools. There are many types of wrenches. Commonly used are socket wrenches, box wrenches, and adjustable wrenches. Commonly used wrenches mostly rely on shear torque to turn nuts, but in actual operation, due to factors such as uneven force, nut type mismatch with wrench type, and nut or wrench manufacturing errors, the outer edges and corners of the bolt or nut are damaged. As a result, slipping is caused, and the nut (or bolt) cannot be tightened or loosened in the end. Summary of the invention [0003] The purpose of the present invention is to provide a non-slip wrench with a simple structure, which can effectively protect the nut and is not easy to slip. [0004] The basic technical solut...

AI Technical Summary

Problems solved by technology

Most of the commonly used wrenches rely on shear torque to turn the nut, but in the actual operation process, the outer corners of the bolt or nut are often damaged due to factors such as uneven force, mismatch between the nut model and the wrench model, and manufacturing errors of the nut or wrench. And cause slippage, and finally can not complete the tightening or loosening of nuts (or bolts)
