The invention discloses a recloser of a circuit breaker. The recloser comprises a shell, a forward and reverse rotation motor, a spindle and a driving handle, wherein the forward and reverse rotation motor is arranged in the shell, and the driving handle is used for driving a handle of the circuit breaker in linkage. A transmission blade and a transmission part are rotatably arranged on the spindle, the forward and reverse rotation motor is matched with the transmission blade in a driving and connecting manner, a transmission gear taking the spindle as a rotation center is arranged on the transmission part, a handle gear in mesh transmission with the transmission gear is arranged on the driving handle, an arc groove is formed in the outer surface of the transmission blade corresponding to the transmission part, the center of the arc groove is positioned on the center line of the spindle, an opening is formed in the anticlockwise edge end of the arc groove in the transmission blade, a linkage shaft is rotatably arranged on the transmission part in a combined manner, and the transmission blade and the transmission part are matched structures which are linked anticlockwise and mutually free clockwise. The recloser has the advantages that the handle of the circuit breaker can be reclosed, response time of normal tripping of the circuit breaker cannot be affected and the like.
