AI Technical Summary
Existing fixtures cannot simultaneously possess both self-locking functionality and adjustable clamping force, resulting in increased operational steps and higher labor intensity.
A clamping device with adjustable clamping force and self-locking function was designed. The clamping force is adjusted by a combination of bolts and pull rods, and it automatically locks after clamping, reducing operation steps.
The clamping force can be adjusted as needed, and no additional operation is required after clamping, which reduces the operator's labor intensity and improves labor efficiency.
