Isolation-circuit break interlocking mechanism for longitudinal rotation type circuit breaker operating mechanism

The invention relates to an isolation-circuit break interlocking mechanism for a longitudinal rotation type circuit breaker operating mechanism, which comprises a machine shell, a circuit breaker mechanism and an isolation mechanism are arranged in the machine shell, a main shaft of the circuit breaker mechanism is arranged in the left-right direction, an isolation operating shaft of the isolation mechanism is arranged in the front-back direction, and a handle connecting section is formed at the front end of the isolation operating shaft; the trigger end of the first interlocking mechanism is located on the front side of the isolation operation shaft, and the locking end of the first interlocking mechanism is suitable for being matched with a closing bent plate of a circuit breaker mechanism; and when the operating handle is connected with the handle connecting section, the operating handle pushes the trigger end to act, so that the locking end locks the closing bent plate to limit the closing of the circuit
