New type circuit breaker driving mechanism

The invention discloses a new type circuit breaker driving mechanism. The mechanism comprises a shell; a rotation shaft is rotatably connected with the shell; a connection plate is fixed at the innerend of the rotation shaft; a long channel is formed in the connection plate; a pair of cross bars which are longitudinally opposite to each other are fixed on the shell; a frame body is arranged at the shell; the frame body is inserted at the two cross bars; a dial rod matched at the long channel is fixed on the frame body; a group of dial pieces which are opposite to each along the moving direction of the frame body are fixed at the frame body; a spline groove is formed in the outer end of the rotation shaft; pressure springs mounted on the cross bars are arranged between the frame body and the shell; and fixed plates are fixedly mounted on the left and right sides of the shell. The mechanism is ingenious and reasonable in structural design, is capable of correctly controlling the on or off state of circuit break
