The nut 25 is rotated on the outer edge of the threaded barrel 18 until the outer edge of the nut 25 moves to the outer edge of the arc plate 19, and the nut 25 is rotated on the outer edge of the arc plate 19, so that the nut 25 is used to squeeze the arc plate 19 and push the rubber plate 20 to shrink. When the anti-corrosion and thermal insulation coating required for spraying is pushed inside the nozzle 16, the anti-corrosion and thermal insulation coating pushes the stirring blade 22 to rotate, and then the stirring blade 22 is used to drive the rotating shaft 23 to rotate, and the rotating shaft 23 is used to drive the threaded ring 24 to rotate. During the rotation of the threaded ring 24, the gap between the outer edge of the threaded ring 24 and the arc plate 19 assists the stable discharge of the anti-corrosion and thermal insulation coating, thereby facilitating the adjustment of the output of the anti-corrosion and thermal insulation coating, and the outer edge of the threaded ring 24 is used to scrape the inner wall of the arc plate 19, so as to assist the self-cleaning of the inner wall of the arc plate 19 and avoid the residual coating on the inner wall of the arc plate 19.
