Problems solved by technology

[0002] A wrench is one of the common hardware tools, it can easily twist nuts and screws; the traditional wrench includes fixed teeth and movable teeth, and the movable teeth are controlled by adjusting the screw during use, so that the movable teeth are close to or far away from the fixed teeth, and then suitable for Nuts of different sizes; therefore, it takes a certain amount of time to adjust the traditional wrench before use. When it is necessary to twist nuts of different sizes, repeated adjustments are required, which is inconvenient to use; at the same time, the movable teeth of the traditional wrench are easy to loose. In the process of use, there are often loose bites, which affect the work progress; in addition, loose bites can easily cause components to collapse and fly, posing certain safety hazards

Abstract

The invention relates to a circular universal spanner. The circular universal spanner comprises a shell; the shell takes the shape of a cylinder with a closed top end; a storage power supply is fixed on the inner top surface of the shell; an on-off switch of the storage power supply is arranged at the top of the shell; a closed liquid storage cavity is formed below the storage power supply; a water replenishing hole and a drain hole are formed in the liquid storage cavity; the drain hole is formed in the lower bottom surface of the liquid storage cavity; an elastic film sealed with the shell is arranged at the lower part of the liquid storage cavity; the elastic film, the shell and the lower bottom surface of the liquid storage cavity surround a twisting cavity; a plastic material is filled in the twisting cavity; the plastic material is high in hardness during drying and low in hardness during wetting; and heating wires are arranged in the twisting cavity, and are electrically connected to the storage power supply. The circular universal spanner is novel in structure and stable and tight in engaging force, can easily and safely twist a valve, and effectively improves the working safety and stability.
