Through the arrangement of the insulating pad 401, the lifting fork 402, the support frame 403, the connecting rod 404, the hinge seat 405 and the pedal 406, during use, the insulating pad 401 is located at the bottom of the switch gate 2 to provide insulating support to prevent current leakage. The lifting fork 402 is used to lift the switch gate 2 and disconnect it. When it is needed, the pedal 406 is pressed by the foot.
