[0033] Example 3

[0034] As an embodiment of the present invention, further, the outer wall of the slide bar 5003 is provided with a spring 5004, and the spring 5004 is located between the fixed plate 5001 and the clamping plate 5002. The spring 5004 is used in a set, so that it can elastically push the clamping plate 5002, prompting the two clamping plates 5002 to clamp the two sides of the stacked paper and keep them in the same position. One end of the slide bar 5003 is passed through the perforation and is threadedly connected with an anti-drop cap 5005. The anti-drop cap 5005 is used to prevent the slide bar 5003 from being separated from the perforation. The workbench 100 is provided with a pusher located at the two clamping mechanisms 500. The paper mechanism 600 includes a push plate 6001. The top surface of the workbench 100 is provided with a slide groove that engages with the push plate 6001.
