The adjustment component 3 includes a rack 4 and a damping gear 5. The rack 4 is provided with two groups, and the two groups of racks 4 are respectively connected to the surfaces of the left paper limiter 2 and the right paper limiter 21. The damping gear 5 is located between the two adjacent groups of racks 4, and the damping gears 5 are respectively It is meshed with the two racks 4, and the surfaces of the left paper limiter 2 and the right paper limiter 21 are also provided with fixing screw grooves 6. The ends of the racks 4 are provided with mounting grooves 41, and the racks 4 are fixed to the left paper limiter 2 and the right paper limiter 21 by using bolts to cooperate with the mounting grooves 41 and the fixing screw grooves 6. The surface of the upper cover 1 is integrally injection-molded with two anti-rotation bars 11, and anti-rotation holes 51 are provided at both ends of the damping gear 5. When the rack 4 needs to be fixed, the anti-rotation hole 51 is inserted into the interior of the anti-rotation bar 11 by pressing the damping gear 5.

[0018] During implementation, the damping gear 5 is pulled outward to disengage the stop hole 51 and the stop bar 11. At this time, the damping gear 5 and the rack 4 are also in a meshing state. Then, the damping gear 5 is rotated half a circle or a full circle, and the damping gear 5 is meshed with the rack 4 to drive the left paper limit piece 2 and the right paper limit piece 21 to slide inward or outward.

[0019] Furthermore, if Figure 3 as well as Figure 4As shown, the bottom end of the upper cover 1 is covered with a lower shell 7, and a sliding component 8 is provided between the lower shell 7 and the left paper limit piece 2 and the right paper limit piece 21.
