Abstract

The invention relates to the technical field of hardware tools, and provides a wrench. The wrench comprises a first guide column, a connecting column, a first jaw, a second jaw, a hollow sleeve, a connecting block and a connecting assembly, the second jaw is arranged at the end portion of one side of the sleeve, the sleeve is provided with a notch, the connecting column is located inside the sleeve and is connected with the first guide column, the connecting column moves in the length direction of the sleeve, so that the first guide column moves in the length direction of the notch, the firstend of the connecting block is hinged to the sleeve, the second end of the connecting block is provided with the first jaw, moreover, the distance between the second end of the connecting block and the first jaw is adjustable, the first end of the connecting assembly is hinged to the first guide column, the second end of the connecting assembly is hinged to the sleeve, and the third end of the connecting assembly is hinged to the third end of the connecting block. According to the wrench, the distance between the first jaw and the second jaw is adjusted by adjusting the distance between the first jaw and the second end of the connecting block to be capable of being suitable for nuts or bolts with different sizes, and the screwed-down nuts or bolts can be conveniently clamped out.

Description

technical field [0001] The invention relates to the technical field of hardware tools, in particular to a wrench. Background technique [0002] In the mechanical field, wrenches are often used when processing, assembling or maintaining products. At present, the size and shape of the socket hole of a socket wrench are fixed, which limits its scope of use and can only be used in corresponding nuts or bolts. At the same time, the existing socket wrenches do not have the clamping function. After the nuts or bolts are twisted off, people often need to pick them up by hand, or use other tools to pick up the nuts or bolts, especially in narrow equipment. Tighten a nut or bolt into a deep hole, or loosen a nut or bolt in a deep hole. Contents of the invention [0003] The purpose of the present invention is to provide a wrench applicable to nuts or bolts of different sizes and shapes, so as to solve the problem that existing wrenches are only suitable for nuts or bolts of a spec...
