The height of the printing roller body 2 is reached, and finally the staff uses the pressing block 708 to allow the slide bar 707 to drive the limiting block 709 to release the clamping state of the clamping slot 710, and at the same time pulls the pulling block 704 to release the insertion rod 703 from the clamping state of the printing roller body 2, and removes it for cleaning or replacement. Then, the first return spring 702 is used to push the insertion rod 703 to restore the clamping state of the printing roller body 2. At the same time, the second return spring 706 acts on the slide bar 707, allowing the limiting block 709 to be clamped and connected with the clamping slot 710, limiting the movement of the insertion rod 703, and completing the installation of the printing roller.
