Description

A kind of spanner

Technical Field

The utility model relates to a hardware and tools technical field especially relates to a spanner.

Background

Wrenches are hand tools that use the principle of leverage to turn bolts, screws, nuts and other threaded fasteners that hold open or trepanned bolts or nuts tight. The wrench is usually provided with an opening or a sleeve hole at one end or two ends of the handle part for clamping the handle part and applying external force to the handle part so as to screw the bolt or the nut and hold the bolt or the nut. When the screw is used, external force is applied to the handle part along the rotation direction of the screw thread, so that the bolt or the nut can be screwed. The wrenches are basically divided into two types, a dead wrench and an adjustable wrench, the dead wrench: one or both ends of the nut are provided with openings with fixed sizes for screwing nuts or bolts with certain sizes. An adjustable wrench: the width of the opening can be adjusted within a certain size range, and bolts or nuts with different specifications can be screwed. However, both a dead wrench and an adjustable wrench have certain defects, the specification of the dead wrench is too many, each wrench can only be used for screws of one type or two types, and the application range is narrow; the adjustable wrench has the convenience of random adjustment but has the appearance of easily leading the outer hexagonal round head, and can not be used for the inner hexagonal screw.
