The utility model can clamp different workpieces by means of the motor compartment and the motor inside the motor, and can facilitate processing and assembly thereof by means of the plurality of clamps and clamping plates provided. At the same time, the clamp can be conveniently disassembled and assembled by means of the provided fixing clips, square clips and fixed protrusions, and maintenance is convenient. At the same time, the fixed plate, roller plate, circular through hole and circular protrusion, annular slot and circular groove can be rotated in a state where they correspond to each other, so that multiple workpieces can be processed and assembled in sequence, which is convenient to use and increases work efficiency.
