Rapid breaking device of traction direct-current circuit breaker

According to the traction DC circuit breaker rapid breaking device provided by the utility model, when breaking is needed, an emergency breaking rod is pushed backwards at the front side of a handcart manually, and because the bottom end of a movable column is inserted into a groove of the emergency breaking rod, the movable column is pushed upwards to drive a connecting arm to further incline towards the rear upper part, so that a straight rod of a breaking mechanism is pulled for breaking; the direct-current circuit breaker can also be moved relative to the emergency opening rod by manually rotating the lead screw through a tool on the front side of the handcart, and the bottom end of the movable column is inserted into the groove of the emergency opening rod, so that the movable column is ejected upwards to drive the connecting arm to further incline towards the rear upper part, and a straight rod of the breaking mechanism is pulled for breaking. In addition, magnetism can be generated by electrifying the
