[0027] The working principle is as follows:

[0028] First, during use, the polyurethane rubber sleeve 2 is fixed to the roller core 1 through the cooperation of the connecting block 32, the fixing block 31 and the movable rod 343 for use;

[0029] Second, when the polyurethane rubber sleeve 2 is damaged after being used for a while, it needs to be replaced. Push the adjusting plate 34104 downward. When the adjusting plate 34104 moves, it drives the limiting block 34103 to move. When the limiting block 34103 moves, it squeezes the second spring 34106. When the limiting block 34103 moves, the limiting effect on the movable block 348 is cancelled;

[0030] Third, push the movable block 348 to the right. When the movable block 348 moves, it pushes the hinge member 346 to move through the connecting rod 347. When the hinge member 346 moves, it drives the movable rod 343 to move, so that the movable rod 343 moves out of the clamping groove 344. When the movable rod 343 moves, it squeezes the first spring 345;

[0031] Fourth, when the movable rod 343 moves out of the clamping groove 344, the fixation of the movable rod 343 on the connecting block 32 can be cancelled, and the polyurethane rubber sleeve 2 can be taken out. When taking out, release the movable block 348. When the polyurethane rubber sleeve 2 is completely taken out, after the second spring 34106 and the first spring 345 lose their acting forces, they release the spring potential energy to push the limiting block 34103 and the movable rod 343 to move;

[0032] Fifthly, when placing the new polyurethane rubber sleeve 2, repeat Step 2 and Step 3 to move the movable rod 2 into the fixed groove 341, and push the polyurethane rubber sleeve 2. When the polyurethane rubber sleeve 2 with the card slot 344 moves to the top of the movable rod 343, after the first spring 345 loses its acting force, it releases its elastic potential energy to push the movable rod 343, causing it to extend into the card slot 344. When the movable rod 343 moves, it drives the hinge member 346 to move. When the hinge member 346 moves, it pushes the movable block 348 to move through the connecting rod 347. When the notch of the movable block 348 moves to the top of the limit block 34103, the second spring 34106 loses its acting force and releases its elastic potential energy to push the limit block 34103 to move, causing the limit block 34103 to extend into the movable block 348 to fix it. Thus, the fixation of the polyurethane rubber sleeve 2 is completed and it can be put back into use.
