The placing plate 42 is combined with the connecting tube 41 and the stabilizing ring 3 by conventional means (such as screw connection). The workpiece B can be placed on the placing plate 42. The surface of the workpiece B can be sandblasted by holding the spray gun in one hand. When the other hand rotates the rotating rod 22, the support ring 23 and the stabilizing ring 3, the workpiece B can be sandblasted. When the ring 3 rotates 90 or 180 degrees, the angular position of the placed workpiece B can be changed to facilitate processing at different positions of its outer surface. In addition, the adjusting rod 43 can be rotated to rotate the stabilizing ring 3 and the bracket 4 to an appropriate angle inside the support ring 23, thereby flipping the bracket 4 and the workpiece B on the placement plate 42, thereby achieving the purpose of processing different surfaces of the workpiece B. The side of the placement plate 42 away from the connecting tube 41 is connected to the first mesh ring 32 on the stabilizing ring 3, and the placement plate 42 supports the workpiece B.

[0027] In this embodiment, a rolling body 231 is provided inside the support ring 23 and is in rolling connection with the stabilizing ring 3 . The stabilizing ring 3 is in rolling contact with the rolling body 231 , which does not affect the rotation of the stabilizing ring 3 , thereby achieving the purpose of adjusting the angle of the bracket 4 .

The blocking ring 31 can be set to a mesh shape or a curved shape with a sloped cross-section. When the bracket 4 rotates, the workpiece B on the storage plate 42 flips over on the stabilizing ring 3, and the blocking ring 31 can block the workpiece B to prevent it from falling.

[0033] The working principle and use process of this utility model:

[0034] When surface treatment is performed on the workpiece B, the workpiece B is placed on the storage plate 42, and the protective worker inserts his hands into the protective gloves in the sandblasting machine housing 1 and processes the workpiece B with the spray gun.

[0035] When it is necessary to process different surfaces on the outer side of the workpiece B, the rotating rod 22, the supporting ring 23 and the stabilizing ring 3 are rotated 90 or 180 degrees by one hand to change the angular position of the placed workpiece B so as to process different positions on its outer surface.

[0036] Rotate the adjusting rod 43 to rotate the stabilizing ring 3 and the bracket 4 to a suitable angle inside the supporting ring 23, thereby turning the bracket 4 over;

[0037] When the bracket 4 rotates, the workpiece B on the placement plate 42 flips over on the stabilizing ring 3, and the blocking ring 31 can block the workpiece B to prevent it from falling, thereby achieving the purpose of processing different surfaces of the workpiece B;

[0038] To sum up: the sandblasting machine is designed to adjust the position of the workpiece. When the rotating rod 22, the support ring 23 and the stabilizing ring 3 are rotated 90 or 180 degrees, the angular position of the placed workpiece B can be changed. When the bracket 4 rotates, the workpiece B on the placement plate 42 is flipped on the stabilizing ring 3, and the blocking ring 31 can block the workpiece B, making it convenient to perform surface treatment on different surfaces of the workpiece B.
