The driving shaft 104 drives the energy storage mechanism to store energy through the cam mechanism 105, so that the operating mechanism is in a stable energy storage state. When the circuit breaker is in an open state and the operating mechanism is in an energy storage state, the energy storage mechanism can be driven to release energy through a closing button, so that the energy releasing energy storage mechanism drives the connecting rod mechanism 103 to drive the main shaft 102 to rotate in a closing direction, and then drives the movable contact to contact with the static contact, thereby realizing closing.
