At the same time, the position of the limit plate 701 and the limit pad 703 can be adjusted according to the label papers of different sizes. When adjusting, the limit bolt 707 is rotated to make it rotate and move inside the threaded hole 708. After the limit bolt 707 is separated from the fit with the surface of the positioning frame 601, it can be separated from the limitation of the slider 705. Then the limit plate 701 can be moved so that the limit plate 701 moves under the limitation of the slider 705 sliding inside the groove 704, and when it moves to the appropriate position, the limit bolt 707 is rotated again to limit the position of the slider 705, so that the limit plate 701 remains stable after moving.

[0032] A handle slot 702 is provided at the center of the top of the limiting plate 701 ; during operation, the handle slot 702 facilitates the movement of the limiting plate 701 .
