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.

The traditional wrench with larger opening is usually designed into a dead-mouth form in order to prevent slipping due to larger applied torque, namely, the opening size is not adjustable, so that the flexibility and the universality of the use are poor; and traditional spanner can't be applied to the dismantlement of cylindric part, and the use limitation is great.
