The driving motor 16 drives the active shaft 10 to rotate, drives the gear 12 and the rack 13 to rotate, thereby driving the conveyor belt 14 to rotate, and the conveyor belt 14 drives the cable to move along the cable conveying channel. When one end of the cable completely passes through the cable conveying channel and between the two groups of limit rollers 22 at the other end, the limit motor 18 drives the bidirectional screw 17 to rotate, drives the two slides 19 to approach each other, and clamps and limits the cable through the two arc-shaped clamping blocks 20.
