The slip ring 25 drives the limit plate 28 to move, and the limit plate 28 drives the sleeve 26 and the sliding ring 27 to move, thereby pushing the connecting seat 39 to move through the sliding ring 27, and the connecting seat 39 drives the rotating frame 22 to move, so that the rotating frame 22 rotates around the connecting head 40 and drives the nozzle 41 to rotate, thereby achieving the problem of adjusting the spray angle of the nozzle 41, and then improving the coating efficiency of the products that need to be galvanized.
