A chute is arranged in the inner side of the installation groove. A sliding plate for stirring a switch key is installed in the chute. The outer side surface of the sliding plate is connected with a push rod. The outer end of the push rod is connected with a rotating arm. The rotating arm is installed on a rotating base. The operator comprises a shell and a rotating shaft installed in the shell. A handle is installed at the outer end of the rotating shaft. A shaft coupling is connected between the inner end of the rotating shaft and the rotating base. A torsion spring sleeves the shaft coupling. Two ends of the torsion spring are connected with the shaft coupling and the housing. A rim for stirring the switch key is arranged at the inner side of the sliding plate. The sliding plate is driven to slide back and forth in the chute under cooperation function of the push rod, the rotating arm, the rotating base and the rotating shaft. When the switch trips out and is closed, the sliding plate is driven to slide backwards under action of the torsion spring on the shaft coupling and controls closing of the switch key automatically.
