The trigger member 21 is acted on by the spring shaft, and its free end falls into the limit groove 23. The clamping assembly 1 is changed from the self-locking state to the open state, so that the high-voltage line is released from the clamping of the clamping assembly 1 for removal, and the wiring assembly 5 connects multiple wiring tools in series and automatically adjusts the length of the wire 54 according to the wiring points with different spacings.
