The operating mechanism comprises a support, a handle lever assembly, a lock catch assembly and a connecting rod mechanism. The handle lever assembly and the lock catch assembly are rotatably arranged on the support, the lock catch assembly is matched with the connecting rod mechanism in a hasp mode to lock or unlock the connecting rod mechanism, and the handle lever assembly drives the connecting rod mechanism to move to achieve closing and opening of the circuit breaker. The transmission mechanism is driven by the handle lever assembly and is switched between a first position and a second position, when the handle lever assembly is in a closing or tripping position, the transmission mechanism is in the first position, the transmission mechanism and the lock catch assembly are separated, and the operating mechanism can be tripped; when the handle lever assembly is in the opening position, the transmission mechanism is in the second pos
