Description

technical field [0001] The invention relates to a hand tool for tightening nuts and other parts, in particular to a single-handed adjustable wrench. Background technique [0002] The movable wrench of the prior art generally includes a handle and a fixed pliers body connected to the front end of the handle, a movable pliers body and a worm installed on the front end of the handle, and the movable pliers body is connected to the worm drive. When in use, the worm is rotated by fingers to make the movable pliers touch the nut, and then the wrench is turned with force to tighten or loosen the nut. The problem with this adjustable wrench is that when the operating space is limited and the wrench cannot be turned around, it can only rotate at a small angle each time. When needing to continue to tighten or unscrew the nut, the wrench must be taken out, put on and tighten again after turning an angle, this action often will be repeated many times, and it is very inconvenient to use...

AI Technical Summary

Problems solved by technology

The problem with this kind of adjustable wrench is that when the operating space is limited and the wrench cannot be turned around, it can only rotate a small angle each time.

When it is necessary to continue tightening or loosening the nut, the wrench must be taken out, turned at an angle, and then tightened again. This action often needs to be repeated many times, which is very inconvenient to use.
