In this embodiment, the lifting plate 11 may be driven by the lifting mechanism 10, where the lifting plate 11 abuts against the bottom side of the limiting member 181 and lifts upward, so as to pull up the connection shaft 180. Specifically, after the cable is clamped by the cable clamp assembly 140 and the positioning sleeve 130 needs to be sleeved on the pin, the positioning sleeve 130 only needs to be lifted upwards by the lifting mechanism 10, and the cable clamp assembly 140 does not need to move downwards after being clamped by the cable clamp assembly 140. Thus ensuring that the wire clamp assembly 140 and the cable remain stationary, the locating sleeve 130 can be slipped over the pin leg, avoiding the problem of the wire clamp assembly 140 pulling the cable.
