[0024] In this embodiment, the cable is passed through the guide hole 11 and tightened so that the cable is in close contact with the inner wall of the guide hole 11, and the cable is preliminarily limited. The cable is passed through the corresponding pair of clamping plates 10, and the dual-axis motor 4 is controlled to drive the pair of screws 6 to rotate. The sliding rod 8 drives the sliding frame 9 and the clamping plate 10 to move, and the cable is adaptively clamped. The cable is further limited, and the sliding frame 9 is dragged to drive the clamping plate 10 to slide along the sliding rod 8. The sliding frame 9 squeezes the protrusion 14 and deforms the protrusion 14 until the protrusion 14 recovers its shape and engages with the corresponding slot 15.
