[0031] Working principle: when in use, the power output shaft of the driving motor 1 rotates to drive the reducer 2 to rotate. At this time, the reducer 2 decelerates the driving motor 1, and the power output shaft on the reducer 2 rotates to drive the rotating head 3 and the plug blade 4 to rotate. When the rotating head 3 rotates, the large bevel gear 501 rotates with it, and the large bevel gear 501 rotates to drive the small bevel gear 502 to rotate. The small bevel gear 502 rotates to drive the vertical rod 503 to rotate. The vertical rod 503 rotates to drive the toothed disc 507 to rotate. The toothed disc 507 rotates to drive the connecting gear 510 and the rotating rod 51 1 and the connecting rod 512 rotate, at this time, the worm 514 rotates with the connecting rod 512, and the worm 514 drives the worm wheel 518 to rotate when rotating, and the worm wheel 518 rotates to drive the screw rod 519 to rise, and the screw rod 519 drives the connecting bracket 520 to rise when rising, and the connecting bracket 520 can drive the driving motor 1, the reducer 2, the rotating head 3 and the flow-pushing blade 4 to rise when rising, and gradually the contact piece 525 on the connecting bracket 520 will contact the bottom of the rack 607, and at this time the rack 607 moves upward to drive the gear 2 60 5 rotates counterclockwise, the gear 2 605 rotates counterclockwise to drive the gear 1 604 to rotate clockwise, and the rotating shaft 602 rotates following the gear 1 604. At this time, the standing board 603 can be changed from a vertical state to a horizontal state, and the maintenance personnel can stand on the standing board 603 to inspect the driving motor 1, the reducer 2, the rotating head 3 and the plug flow blade 4. When the rotating head 3 rotates in the opposite direction, the connecting bracket 520 moves downward. At this time, the reset column 524 on the long column 521 contacts the rack 607, and the rack 607 is pressed downward by the reset column 524. The rack 607 moves downward to drive the gear 2 605 to rotate clockwise, and the gear 2 605 rotates clockwise to drive the gear 1 604 to rotate counterclockwise, and the rotating shaft 602 rotates along with the gear 1 604.
