During electric machine rotation, described screw flight driven gear sheet moves upward, described gear rotates counterclockwise, projection on described gear drives extension spring, moving contact is pulled to the right and separates with fixed contact, when gear in described gear sheet all forwards to above screw flight, screw rod skids, can not be locked by gear, when motor rotates backward, described screw flight driven gear sheet moves downwards, described gear rotates clockwise, projection on described gear drives extension spring, moving contact is promoted left be close to fixed contact, when gear in described gear sheet all forwards to below screw flight, screw rod skids, can not be locked by gear.
Further, described screw rod, gear are made by insulating material.
Further, the number of gears in described gear sheet is identical with the number of threads on described screw rod.
Further, described shunt is manganese copper diverter.
The beneficial effects of the utility model are:
1, structure is simple, be skillfully constructed, good stability, according to the principle of screw rod and gear, the number of gears in gear sheet is identical with the number of threads on screw rod, when electric machine rotation, screw flight driven gear sheet moves upward, gear rotates counterclockwise, and the projection on gear drives extension spring, is pulled to the right by moving contact and separates with fixed contact; When the gear in gear sheet all forwards to above screw flight, screw rod skids, can not be locked by gear, when motor rotates backward, screw flight driven gear sheet moves downwards, and gear rotates clockwise, projection on gear drives extension spring, is promoted left by moving contact to be close to fixed contact; Now, when the gear in gear sheet all forwards to below screw flight, screw rod skids, can not be locked by gear.
2, according to lever principle, the gear of gear sheet is greater than the protruding arm of force to the gear center of circle to the arm of force in the gear center of circle, and motor only has by little power by stretchy moving contact, and life of product is long.
