[0047] The film moves to the side close to the protrusion 30 under the action of the rotating shaft 23, and when the film moves to the surface of the protrusion 30, the two sides of the film are limited by the protrusion 30, and the center position of the film is sprayed by the atomizing water, and then under the action of gravity, the film will present a concave state of low in the middle and high on both sides, so that the center region of the film first contacts the surface of the instrument panel, and then the film is separated from the protrusion 30, so that the film gradually covers the surface of the instrument panel from the center to the two edges, so that the air between the film and the instrument panel is also transported from the center to the two edges under the action of the atomizing water during the covering process, and the effect of eliminating bubbles is further achieved;

[0048] When the nut 21 moves to the side of the sliding groove 12 away from the machine body 1, at this time the film is completely separated from the protrusion 30, and attached to the surface of the instrument panel, then the nut 21 continues to reset under the action of the rotating screw 13, at this time the rotating shaft 23 is separated from the surface of the instrument panel, and the rotating motor stops rotating, then during the reset process of the nut 21, the nut 21 drives the support frame 22 to reset, the support frame 22 drives the rotating shaft 23 to reset, during the reset process of the rotating shaft 23, the air pump delivers the external gas to the gas delivery pipe in the sliding sleeve 26 through the pipeline, and then through the gas delivery pipe to the gas delivery groove, and finally to the air bag plate 28, so that the air bag plate 28 is affected by the gas pressure and expands, and then the air bag plate 28 covers and wraps the atomizing port 29 during the expansion process;
