Abstract

A wrench comprising: a wrench part for loosening or tightening an object body; a pair of wedge-shaped sliding pieces, which are symmetrically combined inside the wrench part, and between the wrench part and the object body Can move to the outside and slide back and forth between them; the coil spring, which is interposed between the inner bottom surface of the wrench head and the side of the sliding piece opposite to the inner bottom surface, elastically biases the sliding piece The sliding piece is elastically supported against the opening direction of the wrench portion. Since the wrench with this structure has a slidable sliding piece, even in a narrow space, it is not necessary to pull out the wrench head of the wrench, so that the work can be carried out continuously and smoothly, and the structure is improved.

Description

Technical field [0001] The invention relates to a working tool, particularly a wrench used for tightening or loosening bolts or nuts. Background technique [0002] Generally, a wrench is a tool used to tighten or loosen bolts or nuts and other fittings (Fitting), which are classified into various types according to their size and shape. [0003] Wrenches used to loosen or tighten bolts or nuts are generally used in the past. figure 1 and figure 2 The structure shown.
