[0024] More specifically, the controller 10 drives the speed regulating motor 2 to drive the gear 8 through the speed reducer 3, the gear 8 cooperates with the rack 1 to move, so that the door body 7 performs the door opening and closing action.

The auxiliary wheel 6 is fixed on the other side of the mounting bracket 4 and is fixed with the gear 8 as the center, and the adjusting fixed plate 5 is on the screw nut of the auxiliary wheel 6.

[0026] More specifically, the number of the auxiliary wheel 6 is two, and the gear 8 is fixed up and down with the gear 8 as the center, so as to prevent the gear 8 from tilting and ensure the smooth operation of the door body 7.
