step 1: switching on a power supply to ensure that all parts of the whole clamp are connected and fastened, rotating the two connecting rods (642) to enable the connecting rods to be in a horizontal state, and then sleeving the stainless steel pipe (14) on the outer surface of the whole clamping device (6);

step 2: rotating the adjusting nut (681) to enable the two threaded rods (683) to be separated towards two sides, and simultaneously pushing the two clamping plates (65) towards two sides, so that the silica gel pads (66) on the outer sides of the two clamping plates (65) extrude the stainless steel pipe (14), and further the whole stainless steel pipe (14) is fixed;

step 3: the driving motor (10) is started, after the driving motor works, the driving motor is matched with the transmission belt (11) through the two belt pulleys (9), the belt transmission is utilized to keep away from the driving shaft lever (8) to rotate, the shaft lever (8) drives the whole clamping device (6) to rotate, in the rotating process, the two clamping plates (65) are further enabled to clamp the stainless steel pipe (14) through centrifugal force generated by high-speed rotation, meanwhile, under the high-speed rotating condition, the two connecting rods (642) are enabled to be perpendicular to the connecting rods (62) through the centrifugal force, and potential safety hazards caused by the fact that the stainless steel pipe (14) is not clamped and flies out in the rotating process due to improper operation can be avoided;

step 4: start first electric telescopic handle (15), it promotes installation piece (31) and slides backward after the work, make sanding belt (55) be close to and hug closely stainless steel pipe fitting (14) surface, then remove about whole lift support post (4) makes it by artifical manual slip, and then polish stainless steel pipe fitting (14) surface, start second electric telescopic handle (46), it rises and promotes whole burnishing and polishing subassembly (5) and rise through promoting upper connection post (43), change sanding belt (55) and the contact position of stainless steel pipe fitting (14) surface, in order to improve the utilization ratio of sanding belt (55) and the quality of whole burnishing and polishing.
