The operation of the servo motor 13 drives one of the rotating screws 6 to rotate, and the two rotating screws 6 rotate synchronously under the drive of the synchronous wheel 17 and the synchronous belt 18. When the two rotating screws 6 rotate, the threaded sleeves 7 thereon drive the connecting rod 8 to move up and down in the sliding groove 5.
