Circuit breaker with manual energy-accumulating unit gears intitally separated from one another

A circuit breaker comprising:

• circuit breaking unit including a fixed contact and a movable contact whose contact points are in contact with each other;
• and
• energy-accumulating unit for accumulating energy of a closing spring for controlling the contact between the fixed contact and the movable contact,
• wherein the energy-accumulating unit includes:
• main energy-accumulating unit including a cam shaft, a main output gear disposed on the cam shaft, and a main energy-accumulating casing for accommodating the main output gear;
• and
• auxiliary energy-accumulating unit including electromotive energy-accumulating unit linked with the cam shaft, and manual energy-accumulating unit linked with the electromotive energy-accumulating unit, wherein bevel gears inside the manual energy-accumulating unit are engaged with each other by an external force to transmit the input external force to the electromotive energy-accumulating unit to accumulate the energy of the closing spring,
• wherein the bevel gears comprise a primary bevel gear and a secondary bevel gear, and
• wherein the primary bevel gear and the secondary bevel gear are arranged to be spaced apart from each other when the manual energy-accumulating unit is not in operation, and to be engaged with each other when the manual energy-accumulating unit is in operation.
