The invention discloses a safety lever mechanism of a switch machine. The safety lever mechanism comprises a lever stick, a handle spring seat, a handle shaft sleeve, a cam clutch plate, a clutch sliding block, a cam, a lever main shaft and a tail end meshing gear. The pulling rod is fixedly connected with the handle spring seat, and the handle shaft sleeve is located outside the handle spring seat and the clutch sliding block. The cam clutch plate and the cam are sequentially connected to the outer side of the hand-operated main shaft in a sleeved mode, the cam clutch plate and the hand-operated main shaft are fixedly connected together, the cam is fixedly connected with the machine shell, and the other end of the hand-operated main shaft is provided with a tail end meshing gear. A cam clutch plate clamping groove is formed in the outer edge of the cam clutch plate, a cam sliding groove is formed in the side, close to the cam clutch plate, of the cam, and the longitudinal section of the clutch sliding block is in a step shape. According to the hand pulling mechanism of the electric switch machine special for turning of the vehicle, the pulling rod handle is adopted for driving, clutch control is carried out through the cam inserting groove, meanwhile, the end face cam travel switch is installed, double safety measures of a mechanical structure and a circuit are achieved, and reliability is high.
