[0035] By using the PLC controller 25 to start the servo motor 17, the output shaft of the servo motor 17 can then drive the bidirectional threaded rotating rod 16 to rotate, so that the two threaded L-shaped support plates 18 on the bidirectional threaded rotating rod 16 can move toward each other, so that one of the two side plates 22 equipped with the second spring 21 can be driven to first push the opening and closing switch 24 on the circuit breaker operating device 6, and push the opening and closing switch 24 to the other side. Conversely, the other side plate 22 can push the opening and closing switch 24 again, so as to achieve remote control of the opening and closing of the circuit breaker without the need for manual operation by the staff. At the same time, the side plate 22 with elastic force can protect the opening and closing switch 24 to prevent the opening and closing switch 24 from being damaged by excessive thrust, thereby improving the safety of the ring network cabinet fuse switch cabinet during use.
