The rotating seat sends the bracket onto the spiral blade during the rotation process, and the bracket moves along the spiral blade; the hot air enters the guide plate through the air inlet, and the rotating shaft drives the blades to rotate. The blades send the hot air into the spiral blade through the air vents and the air outlet holes to dry the bracket; the dried bracket is discharged between the base and the protective cover.
