The shaft sleeve (5) matched with the shaft (3) rotates synchronously, and the shaft sleeve (5) can drive the hand-operated toggle mechanism (1) to open and close the circuit breaker. At this time, the rotating part (7) does not move, and the boss (8) is outside the movement range of the toggle lever (6) and does not interfere with each other. The motor (9) indirectly provides rotational power for the rotating part (7) through the mechanical transmission mechanism (10), and drives the boss (8) to move when rotating. Both sides of the boss (8) can push the toggle lever (6) to move the shaft sleeve (5) to open and close the circuit breaker. When the movement ends, the rotating part (7) returns to the initial position. The movement of the motor (9) is controlled by the controller (11).

[0006] In particular, the controller (11) is fixed on the housing (4), and the received control signal is transmitted by wired signal or wireless signal; the controller (11) determines that the rotating member (7) drives the hand-operated toggle mechanism (1) to reach the opening and closing position and the initial position.

[0007] Particularly, the mechanical transmission mechanism (10) is a gear, and in this case the rotating member (7) is a gear; the mechanical transmission mechanism (10) may be a synchronous wheel, and in this case the rotating member (7) is a synchronous wheel; the shaft of the motor (9) is matched with the axis of the mechanical transmission mechanism (10) to drive them to rotate synchronously; the motor (9) is fixed on the housing (4), and the housing (4) is fixed on the hand-operated toggle mechanism (1); and the housing (4) has an opening to allow the square shaft (3) to extend out.

[0008] Particularly, one side of the rotating member (7) is attached to the large shaft position outside the small diameter section of the shaft sleeve (5), and the other side is fixed to a preset groove on the shaft sleeve (5) by a retaining spring; the shaft sleeve (5) may be a non-stepped shaft with an outer circle and an inner square, in which case both sides of the rotating member (7) are fixed between two preset grooves on the shaft sleeve (5) by retaining springs, and the shifting rod (6) also serves as a positioning pin for fixing the square shaft (3).

[0009] In particular, when the controller (11) receives a trip signal, the motor (9) starts to rotate, driving the mechanical transmission mechanism (10) to rotate, thereby driving the rotating member (7) to start rotating, and the boss (8) pushes the lever (6) to move; when the circuit breaker reaches the trip position, the controller (11) determines that the hand-operated toggle mechanism (1) operates the circuit breaker to reach the trip position, at which time the motor (9) starts to rotate in the reverse direction, driving the rotating member (7) to rotate, and when the rotating member (7) returns to the initial position, the motor (9) stops rotating.

[0010] In particular, when the controller (11) receives a closing signal, the motor (9) starts to drive the mechanical transmission mechanism (10) to rotate in the opposite direction, driving the rotating member (7) to start moving, and the boss (8) pushes the lever (6) to move; when the circuit breaker reaches the closing position, the controller (11) determines that the manual toggle mechanism (1) has toggled the circuit breaker to the closing position, and the motor (9) starts to rotate in the forward direction, driving the rotating member (7) to rotate; when the rotating member (7) returns to the initial position, the motor (9) stops rotating.
