[0036] Based on the above embodiment, a method for adjusting and using ceramic tube sandblasting is specifically implemented as follows: S1, when it is necessary to perform local sandblasting on the ceramic tube in the production process, the ceramic tube is placed on the clamping mechanism 25, and the cylinder 252 located on the connecting frame 251 is driven to operate so that the piston rod extends outward; S2, as the cylinder 252 extends, the telescopic disc 253 is driven to rotate.
