[0032] Working process: During the use of the device, the external power supply is energized. When clamping the workpiece, the workpiece is placed between the clamping plates 20 and the upper end of the chuck 7, and the servo motor 10 is started. The servo motor 10 drives the threaded rod 11 to rotate. The upper end of the threaded rod 11 is rotatably connected to the inner side of the built-in mounting groove 8 to improve the stability of the threaded rod 11 when it rotates. The rotation of the threaded rod 11 drives the screw disk 12 connected to the outer spiral to move upward.
