Manual energy storage structure of circuit breaker and circuit breaker

The manual energy storage structure comprises a side plate, a rotating shaft, a first pawl, a ratchet wheel, a second pawl and a handle, the rotating shaft is sequentially sleeved with the first pawl, the ratchet wheel, the second pawl and the handle, the first pawl is installed on the side plate in the mode that the first pawl can move in the axial direction of the rotating shaft, and the second pawl is installed on the side plate in the mode that the second pawl can move in the axial direction of the rotating shaft. The first pawl and the second pawl are symmetrically installed on the two sides of the ratchet wheel, the second pawl is installed on the handle in the mode that the second pawl can move in the axial direction of the rotating shaft, and the ratchet wheel can drive the rotating shaft to rotate. According to the manual energy storage mechanism, a traditional radial pawl is improved to be in an end face shape, the structural strength of the manual energy storage mechanism is improved, and meanwhile
