AI Technical Summary
The open-end wrenches used in existing power equipment cannot adapt to parts of different models and diameters, resulting in unstable clamping and slippage, which affects the ease of installation.
The structure of the clamp wrench includes a main arc clamp, a movable arc clamp, bolt assemblies, and clips, which achieve a fully enclosed clamping effect, enhancing adaptability and reliability.
It effectively adapts to clamping parts of different diameters, prevents slippage, ensures clamping reliability, facilitates hand-held torque application, and enables stable disassembly.
