Description

Screw wrench

Technical Field

The utility model relates to the field of hardware tools, in particular to a screw twisting wrench.

Background

A wrench is a commonly used installation and removal tool, and is a hand tool that uses the principle of leverage to turn bolts, screws, nuts, and other threads to tighten the openings or trepanning fasteners of the bolts or nuts. Wrenches are typically manufactured from structural steel of carbon or alloy material. The wrench is usually provided with an opening or a socket for clamping the bolt or the nut at one or both ends of the shank, and when in use, an external force is applied to the shank in the rotation direction of the screw, so that the bolt or the nut can be screwed.

Different spanners correspond to different bolt nuts, so that the same spanners can correspond to different bolt nuts with a certain size range, the adjustable spanners are adopted at present, and the adjustable spanners are simply called adjustable spanners, so that the opening of the adjustable spanners can be adjusted within a certain range, and the adjustable spanners are very convenient to use, can be used for standard metric bolts and English bolts, and can also be used for certain self-made non-standard bolts. In addition to adjustable wrenches, some current wrenches use chains to bind bolts and nuts, so as to realize adjustment of bolts and nuts with different sizes, but the existing wrenches have at least the following problems:

1. The existing spanner is easy to slip and not easy to twist when engine oil is arranged on the bolt and the nut and the bolt and the nut are relatively smooth or when the bolt and the nut rust and the parallel edges and edges are not obvious;

2. The existing wrench, even the adjustable wrench, has a small universal size range;

3. Particularly, the head of the existing adjustable spanner adjusts the size of the plate opening by rotating the turbine, so that the connection between the adjustable spanner opening and the turbine has few contact surfaces, and in the use process, when a large force is needed to pull some bolts and nuts, if the spanner is not good in material, the connection between the turbine and the adjustable spanner opening is easily broken.
