[0022] When opening or closing is required, the first electric telescopic rod 3 is first extended, the push rod 5 is directed toward one side of the opening button 11 or the closing button 12, and the opening and closing operating mechanism is fixed on the housing of the circuit breaker 1 by the magnetic mounting seat 2. Then, the length of the second electric telescopic rod 4 is adjusted according to the position of the opening button 11 or the closing button 12, so that the pressing head 6 at the end of the push rod 5 is aligned with the opening button 11 or the closing button 12. Then, the operator moves away from the circuit breaker 1, inputs a control instruction to the controller 82 through the remote control signal input unit, and controls the first electric telescopic rod 3 to contract through the controller 82, so that the pressing head 6 at the end of the push rod 5 presses the opening button 11 or the closing button 12, thereby realizing the remote control opening and closing operation. In order to prevent the device from damaging the opening button 11 and the closing button 12 of the circuit breaker 1 and the circuit breaker, the device can be set so that when the first electric telescopic rod 3 is contracted to the shortest, the pressing head 6 just reaches the position where the button can be pressed.

[0023] The controller 82 (controller) is a conventional master device that controls the start, speed regulation, braking and reversal of the motor by changing the wiring of the main circuit or the control circuit and the resistance value in the circuit in a predetermined order.

[0024] By using the electric telescopic rod to drive the push rod 5, the pressing head 6 performs the opening and closing operations. The electric telescopic rod runs stably and continuously, and the risk of damaging the circuit breaker 1 mechanism due to excessive pressing can be avoided.

[0025] According to an embodiment of the present application, the magnetic mount 2 includes a shell and a coil installed in the shell, and the coil is electrically connected to the power module 8 through a current regulating switch.
