During the movement, the pulley frame 5 also drives the cable drag chain 6 to be reeled in or out. When the cable drag chain 6 is fully extended, the pulley frame 5 moves to the front limit switch 8, and the pulley frame 5 is stopped by the front limit switch 8; when the cable drag chain 6 is fully reeled in, the pulley frame 5 moves to the rear limit switch 7, and the pulley frame 5 is stopped by the rear limit switch 7.
