When in use, the workpiece can be clamped and released manually quickly by adjusting the jaws and the fixed jaws, and the strength of the clamped workpiece can be adjusted by adjusting the jaws, thereby effectively avoiding work. In the case of damaged parts, the lower part of the workpiece can be supported by the support assembly, which can effectively prevent the workpiece from slipping during processing.
