The rotating motor 210 drives the rotating shaft 211 at the bottom of the connecting plate 29 to rotate, and then drives the upper clamping plate 212 and the lower clamping plate 213 clamping the sheet metal part to rotate synchronously. And through the balls 34 in the accommodating groove 33 at one end of the rotating clamping rings 32 at both ends of the protective outer cylinder 31, it is convenient for the upper clamping plate 212 and the lower clamping plate 213 to rotate. During powder spraying, the excess paint that does not adhere to the surface of the sheet metal part flows into the inner side of the rotating hollow pipe 214 through the flow hole 36 at the top of the lower clamping plate 213, and flows into the paint collecting cabinet 38 through the paint inlet pipe 37 connected to the rotating hollow pipe 214. The paint collecting cabinet 38 can collect the paint that does not adhere to the surface of the sheet metal part, reduce the waste of paint, and increase the recycling of paint.
