And one end of the limiting roller 508 extends to the outside of the rectangular block 3.

[0030] Specific implementation manner: When sandblasting an external plate-shaped workpiece is required, move the two rectangular blocks 3 relative to each other, place the external plate-shaped workpiece between the two rectangular blocks 3 and on top of the support block 4. At this time, the limit roller 508 will come into contact with the surface of the external plate-shaped workpiece, and the support block 4 is used to place and support it. Start the second motor as needed. The second motor drives the rotation of the rotating shaft 502 and the convex block 503. Using the linkage effect among the rotating shaft 502, the convex block 503, and the first bevel gear 505, the power is transmitted to the first bevel gear 505, causing the first bevel gear 505 to drive the second bevel gear 506 to rotate. Then, using the linkage effect between the second bevel gear 506 and the connecting shaft 507, the power is transmitted to the connecting shaft 507, causing the connecting shaft 507 to drive the limit roller 508 to rotate. During the rotation of the limit roller 508, it will drive the external plate-shaped workpiece to move under its action, continuously adjusting the use position of the external plate-shaped workpiece.

When it is necessary to perform sandblasting on an external annular workpiece, make the two rectangular blocks 3 move away from each other. At this time, the rectangular block 3 and the support block 4 will be fixed to the inner wall of the external annular workpiece, and cooperate with the rotating seat inside the sandblasting machine to perform sandblasting on the surface of the external annular workpiece. When it is necessary to perform sandblasting on an external plate-shaped workpiece, make the two rectangular blocks 3 move towards each other, place the external plate-shaped workpiece between the two rectangular blocks 3 and on top of the support block 4. At this time, the limit roller 508 will contact the surface of the external plate-shaped workpiece, and place and support it through the support block 4. Start the second motor according to actual needs. Drive the rotating shaft 502 and the convex block 503 to rotate through the second motor. Utilize the linkage effect between the rotating shaft 502, the convex block 503 and the first bevel gear 505 to transmit the power to the first bevel gear 505, so that the first bevel gear 505 drives the second bevel gear 506 to rotate. Then utilize the linkage effect between the second bevel gear 506 and the connecting shaft 507 to transmit the power to the connecting shaft 507, so that the connecting shaft 507 drives the limit roller 508 to rotate. And the limit roller 508 will drive the external plate-shaped workpiece to move under its action during rotation, and adjust the use position of the external plate-shaped workpiece. Protect the top of the base 1 through the protective layer 7. And during the horizontal movement of the rectangular block 3, it will assist in cleaning the surfaces of the base 1 and the protective layer 7 through the cleaning brush 6, which is convenient to use.
