Referring to fig. 5, a driving motor 502 is coupled to the installation cavity 101, and a driving bevel gear 505 is coupled to an output shaft of the driving motor 502, and the driving bevel gear 505 is engaged with a driven bevel gear 504. The driving motor 502 realizes power transmission through the cooperation between the driving bevel gear 505 and the driven bevel gear 504, thereby driving the pressing cam 501 to rotate.

When the lifting end 403 is at the highest point, that is, when the lifting end 403 is in contact with the second movable engaging member, a space is provided between the pressing end 404 and the pressing cam 501, and the circuit is in a conducting state. At the same time, the first displacement spring 4034 is in a compressed state with elastic potential energy, and the second displacement spring 4044 is in a relaxed state.

When the coil current increases, the iron pillar drives the iron pillar to drive the lifting end 403 to move to the lowest point, and the lifting end 403 is separated from the second movable engaging piece, and is in a trip state at the moment. During "tripping", on the one hand, the pushing force of the second movable engagement member causes the lifting end 403 to gradually move into the lifting opening 401, and on the other hand, the elastic potential energy of the first displacement elastic member 4034 is released, further causing the lifting end 403 to move into the lifting opening 401. During the movement of the lifting end 403 towards the pressure chamber 4, the pressure in the pressure chamber 4 increases gradually, which forces the pressing end 404 to protrude gradually from the sliding port 402 until the lower baffle of the pressing end 404 abuts against the sidewall portion tangential to the short axis of the pressing cam 501, at which time the second displacement elastic member 4044 is in a compressed state.

When the circuit breaker needs to be opened again, the driving motor 502 drives the pressing cam 501 to rotate, the side surface, contacted with the low baffle plate, of the pressing cam 501 gradually moves from the side wall part tangent with the short axis to the side wall part tangent with the long axis, so that the pressing end 404 gradually enters the sliding opening 402, the lifting end 403 is gradually led out of the lifting opening 401, and in the moving process of the lifting end 403, the lifting end 403 pushes the second movable engaging piece, so that the second movable engaging piece is conducted with the circuit again.

In addition, the driving component is also provided with a group on one side of the second movable occluding part facing the iron column, when the driving component is in a circuit conducting state, the side wall part tangent to the short shaft of the pressing cam 501 of the driving component is attached to the end part of the second movable occluding part far away from the rotation center of the second movable occluding part, when the driving component is required to actively disconnect the circuit conducting state, the pressing cam 501 of the driving component rotates, so that the side wall part tangent to the short shaft is attached to the end part of the second movable occluding part far away from the rotation center of the second movable occluding part, and the second movable occluding part is separated from the iron column.

In order to improve intelligence, in this embodiment, the installation cavity 101 is further provided with a 4G remote control module, and the 4G remote control module can be connected to the mobile phone through a 4G signal, so that a user can remotely operate the mobile phone conveniently, and in this embodiment, the two driving components are respectively electrically connected to the 4G remote control module. The 4G remote control module is in the prior art, and will not be described here.
