自制万能扳手
By designing a self-made universal wrench, the problem of handwheel valves getting stuck due to various specifications and rust and scale buildup was solved. This enabled the handwheels of different sizes to be adapted and the torque to be enhanced, improving the ease of operation and torque transmission capability.

AI Technical Summary
Existing tools are difficult to adapt to handwheel valves of different specifications, and cannot transmit sufficient torque under conditions of rust and scaling, causing the handwheel to jam and making operation difficult.
A self-made universal wrench was designed, including components such as a long handle, a rotating disc, an adjusting ring, a push chuck, and a constraint hook. The adjustable fixing structure and the long handle extend the lever arm, adapting to handwheels of different sizes and increasing torque output.
It achieves stable engagement and torque output of handwheels for valves of different specifications, effectively solving the problem of handwheel jamming and enhancing the convenience of operation and torque transmission capability.
