[0042] Specifically, the user places the paper at the inlet 2, starts the printing machine body 1 to work, and makes the printing machine body 1 move the paper at the inlet 2 into the inner side of the printing machine body 1 for printing. The printed paper moves to the position of the guide plate 5 through the outlet 3. The user adjusts the position of the paper and controls the telescopic end of the electric telescopic rod 7 to extend through the printing machine body 1, so that the telescopic end of the electric telescopic rod 7 drives the upper cutter 8 to move downward, so that the upper cutter 8 and the lower cutter 9 cooperate with each other to cut the excess part of the paper.

[0043] In this embodiment, a pulling mechanism is also included. Figure 3 and Figure 4 The pulling mechanism includes a plurality of fixing frames 10 fixedly mounted on the upper cutter 8, an arc bar 11 is rotatably mounted on each fixing frame 10, two first torsion springs 12 are connected to each fixing frame 10, and the two first torsion springs 12 are connected to the arc bar 11 together, and a pressure strip 13 is fixedly mounted on the ends of the plurality of arc bars 11 together, and the pressure strip 13 is made of rubber material and is used to generate friction with the paper.

[0044] Specifically, the user controls the telescopic end of the electric telescopic rod 7 to extend, so that the telescopic end of the electric telescopic rod 7 drives the upper cutter 8 to move downward, and the upper cutter 8 drives the pressure bar 13 to move downward through the fixed frame 10 and the arc bar 11 under the elastic support of the first torsion spring 12, so that the pressure bar 13 cooperates with the first guide roller 16 to pull the paper before the upper cutter 8 contacts the paper, so that the arc bar 11 can rotate around the fixed frame 10 as the center, thereby supporting the paper, so as to facilitate the upper cutter 8 and the lower cutter 9 to cut evenly.

[0045] When the telescopic end of the electric telescopic rod 7 is retracted to the fixed end, the first torsion spring 12 can use its own elastic force to drive the pressure strip 13 to perform a reset operation through the arc strip 11.

[0049] It can be understood that the rotation of the first guide roller 16 can drive the trigger block 39 to rotate, so that the trigger block 39 can squeeze the connecting frame 24, so that the connecting frame 24 drives the pressure plate 25 to move downward through the second torsion spring 26, so that the pressure plate 25 can press the cut waste down and move it into the inner side of the support shell 4.

[0052] Specifically, when the extended position on the second gear 38 is separated from the tooth block 34, the third spring 32 can use its own elastic force to drive the push plate 27 to reset through the movable bar 33, the movable plate 35, the sleeve 36 and the fixed block 28; when a suitable amount of waste is collected in the collecting shell 14, the collecting shell 14 is pulled out of the inner side of the supporting shell 4, so that the collecting shell 14 can be driven by the fixed block 28 and the second spring 29 to move the protrusion 30 away from the inner side of the sleeve 36 under the action of external force, thereby facilitating the processing of the waste in the collecting shell 14, and then the processed collecting shell 14 is moved back into the inner side of the supporting shell 4, and the collecting shell 14 is fixed by the fixed block 28, the protrusion 30 and the sleeve 36.
