[0023] The arrangement starts the stepper motor 21 to rotate, so that the stepper motor 21 drives the rotating column 22 to rotate, so that the rotating column 22 drives the gear 23 to rotate, so that the gear 23 drives the outer gear ring 24 to rotate, so that the outer gear ring 24 drives the rotating block 25 to rotate, so that the rotating block 25 drives the connecting column 26 to rotate, so that the connecting column 26 drives the four-claw clamp 3 to rotate, and then drives the workpiece to rotate.
