When the motor 5 rotates to a position of 15 degrees, the key 42 is in contact with the other end groove wall of the arc-shaped chute 22, when the motor 5 continues to rotate counterclockwise at a position of 15 degrees to 105 degrees, the rotation of the key 42 is limited by the stop of the arc-shaped chute 22, the clutch plate 2 is driven to synchronously rotate counterclockwise by 90 degrees when the key 42 rotates, the clutch plate 2 drives the operating shaft 1 to synchronously rotate 90 degrees, and the electric output control of the operating shaft 1 rotating counterclockwise by 90 degrees is realized. Then, the motor 5 rotates clockwise by 105 degrees and stops, and during the clockwise rotation of the motor 5, the key 42 slides in the arc-shaped chute 22, and at this time, the clutch plate 2 and the operating shaft 1 do not rotate.
