The clamping plate 142 moves in the direction away from the protector shell 1 to squeeze the No. 2 spring. The No. 2 spring is squeezed by the clamping plate 142 and deforms and accumulates force. At the same time, the clamping plate 142 moves in the direction away from the protector shell 1, disengages from the contact with the L-shaped plate 147 and releases the limit of the docking line. When the support plate 132 moves in the direction close to the protector device 3, it drives the load-bearing rod 135 to move and reset.
