When the circuit breaker needs to be moved in the control cabinet, the rotating block 607 is firstly fixed with the bolt 608. 7 is fixed on the surface of the base 602, and then the circuit breaker is moved into the control cabinet by a trolley, and then the specific rotating rod is used to insert the rotating block 607, and then the specific rotating rod is rotated, the support plate 606 will start to move with the circuit breaker body 1, and the pulley 605 moves synchronously. When the circuit breaker body 1 moves to a certain position, the contact point of the plum blossom contact 603 on one side of the surface of the spine 601 will contact the corresponding contact, and then the connector 3 is connected to its corresponding female plug, so as to realize the circuit switching and isolation of the equipment. When the circuit breaker needs to be repaired or replaced, the connector 3 is unplugged, and the rotating block 607 is rotated in the opposite direction using the specific rotating rod. When the circuit breaker body 1 is reset, the handle 604 is pulled to pull out the circuit breaker.

[0019] Furthermore, one end of the bolt 608 passes through the rotating block 607 and is connected to the base 602. Two groups of bolts 608 are provided. Through the provision of the bolts 608, when in use, when one end of the bolt 608 passes through the rotating block 607 and is connected to the base 602, the bolt 608 can fix the rotating block 607 to the surface of the base 602.

Then, the rotating block 607 is inserted into the control cabinet using a specific rotating rod, and then the specific rotating rod is rotated. The support plate 606 will start to move with the circuit breaker body 1, and the pulley 605 will move synchronously. When the circuit breaker body 1 moves to a certain position, the contact point of the plum blossom contact 603 on one side of the surface of the spine 601 will contact the corresponding contact, and then the connector 3 will be connected to the corresponding contact. The corresponding plug-in female connector is connected. After the circuit breaker is installed, a specific rotating rod is used to insert the energy storage knob 5, and then rotated. At this time, the circuit breaker starts to store energy. When it cannot be rotated and a sound is heard, the energy storage is completed. When it is necessary to close the circuit, press the closing switch 4, and the circuit breaker will be closed. When it is necessary to close the circuit, press the opening switch 2, and the circuit breaker will be closed. When the circuit breaker needs to be repaired or replaced, unplug the connector 3, use the specific rotating rod to rotate the rotating block 607 in the opposite direction, and when the circuit breaker body 1 is reset, pull the handle 604 to pull out the circuit breaker.
