The two reciprocating screws 9 pass through the movable plate 15 through the two threaded holes respectively. A brush 23 is fixedly connected to the bottom end of the movable plate 15. A rotating driving mechanism is installed in the driving box 8. The output end of the rotating driving mechanism is fixedly connected to the reciprocating screw 9.

The output shaft of the reduction motor 11 is fixedly connected to the driving gear 12. One end of the reciprocating screw 9 extends into the drive box 8 and is fixedly connected to the driven gear 10. The two driven gears 10 are symmetrically arranged on both sides of the driving gear 12, and the two driven gears 10 are meshed with the driving gear 12. The two driven gears 10 have the same diameter. The reduction motor 11 drives the driving gear 12 to rotate.
