[0024] When in use, the pressure roller 1 can be installed on the equipment through the installation part 16. When the roller sleeve 2 is used for a long time and needs to be replaced due to a fault, the electromagnet 14 is first turned off. The pressure roller 1 is provided with a controller. The electromagnet 14 can be turned off by the controller so that the electromagnet 14 no longer adsorbs the inner wall of the second card slot.
