[0030] When placing the paper roll 2, the staff pulls the limit roller 20 horizontally, and the clamping spring 21 is compressed. After the paper roll 2 is placed, the staff releases the limit roller 20, and the clamping spring 21 will rebound and drive the limit roller 20 to move in the opposite direction and reset.
