A through hole is provided at the center position of the rotating shaft of each operating handle, and the through holes on the operating handles on both sides are connected. Two transmission shafts are provided, which are respectively located on both sides of the rotating mechanism. This overcomes the shortcomings of the prior art and provides a new type of synchronous transmission mechanism used on a circuit breaker, which can well solve the problem of three-phase asynchronism after the circuit breaker is closed and reduce the phenomenon of circuit breaker slippage and tripping.
