When the polishing process is performed, the pressing block 42 needs to be pressed tightly against the product 12 to prevent the product from falling off during the polishing process. The anti-slip lifting driving member 47 may be a cylinder. Specifically, before the process of polishing begins, the output end of the anti-falling lifting driving piece 47 extends out to push the anti-falling seat 41 to descend, and at the moment, the guide column 45 descends simultaneously, so that the pressing block 42 at the bottom of the anti-falling seat 41 falls stably. The pressing block 42 continuously falls until the positioning protrusion 49 completely falls into the positioning hole 48 on the fixing seat 22, so that the fixing seat 22 is fixedly connected with the anti-falling seat 41, at this time, the pressing block 42 also tightly pushes the top of the product 12, and then the polishing process can be started. After polishing, the output end of the anti-dropping lifting driving element 47 is retracted to drive the positioning protrusion 49 on the anti-dropping seat 41 to leave the fixed seat 22.
