A lead screw pendulous device for spinning

The utility model provides a lead screw pendulous device for spinning, includes the fixing base, driving motor, and commutator and actuating lever, driving motor set up on the fixing base, and drivingmotor's output shaft is connected with the commutator transmission, and the surface of commutator is provided with spiral shell hand groove, the setting of removal ground can be controlled on the fixing base by the relatively fixed seat to the actuating lever, the one end of actuating lever is connected with the spiral shell hand groove of commutator, and the other end of actuating lever is connected with the lead screw, and when the commutator is rotated by drive motor drive, thereby the one end of actuating lever removes the drive lead screw in the spiral shell hand groove of commutator about. Its advantage is: be the left and right sides removal of actuating lever on the horizontal direction with driving motor's rotation sport conversion to removing about driving the relative spinningof lead screw, because the
