The working principle of the utility model is as follows: in the closing process of a closing device 2 of the circuit breaker operating mechanism, the energy storage maintaining shaft 21 can rotate and drive the main shaft 1 to rotate. When the energy storage holding shaft 21 rotates to a certain angle, the energy storage holding shaft is fixed with other parts. In order to prevent the energy storage retaining shaft 21 from being fixed and failed with other components to generate secondary closing, the driving piece 6 arranged on the main shaft 1 is used for pushing the moving assembly 5 on the mounting plate 3 to move towards the energy storage retaining shaft 21 by the driving piece 6 when the main shaft 1 rotates, so that one side of the moving assembly 5 is matched with the limiting pin 4 on the energy storage retaining shaft 21, the energy storage retaining shaft 21 cannot rotate, and secondary closing is prevented.
From the above description, the beneficial effects of the present invention are: the driving piece 6 is driven to rotate by the rotation of the main shaft 1 during the closing operation, so that the moving assembly 5 is pushed towards the energy storage maintaining shaft 21, and one side of the moving assembly 5 is matched with the limiting nail 4 of the energy storage maintaining shaft 21, so that the energy storage maintaining shaft 21 cannot rotate, and secondary closing is prevented; the structure is simple, the operation is stable, and secondary closing can be effectively prevented.
Further, the moving assembly 5 includes a fixed pin 51 and a moving plate 55, the moving plate 55 is provided with a moving hole 52 facing the energy storage holding shaft 21 in the length direction, and the fixed pin 51 passes through the moving hole 52 and is locked on the mounting plate 3.
As can be seen from the above description, the moving plate 55 is moved on the mounting plate 3 by a certain distance through the moving hole 52 and the fixing nail 51 of the moving plate 55.

Further, the moving plate 55 is disposed below the energy storing and holding shaft 21.
As will be understood from the above description, the position of the moving plate 55 is set such that the moving plate 55 can be quickly disengaged from the limit pin 4 of the energy storage maintaining shaft 21 by its own weight in combination with the restoring force of the restoring spring 53 after the driving member 6 is no longer pushed upward. The release of the engagement with the stopper pin 4 of the energy storage holding shaft 21 can be achieved by only the self-weight when the return spring 53 fails.
Further, the driving member 6 is a cam.
