[0033] In this embodiment, the slide cylinder 20 is provided to guide and support the guide rod 19 .

[0034] Working principle: When it is necessary to clamp and support documents of different sizes, the staff pulls the movable plates 12 on both sides in turn, so that the movable plates 12 drive the extension plate 11 to move, and at the same time, the extension plate 11 drives the guide plate 16 to slide on the inner surface of the guide groove 17, and the extension plate 11 drives the stud 13 to slide on the inner surface of the moving groove 15. When the movable plates 12 on both sides drive the extension plate 11 to move to the appropriate clamping support spacing, the staff turns the limit nuts 14 on both sides in turn, so that the limit nuts 14 are turned on the outer surface of the stud 13. The movable plate 12 and the second limiting plate 18 are moved to fit closely with the connection of the back plate 9, so as to limit the connection of the extension plate 11 and the back plate 9, so as to complete the adjustment of the clamping distance of the documents of different sizes. Then, the staff unfolds the document, and then inserts the document downward from between the movable plate 12 and the second limiting plate 18, so that the bottom of the document is inserted into the inner cavity of the first limiting plate 10, and the back of the document is closely fitted with the back plate 9, so that the first limiting plate 10, the second limiting plate 18, the movable plate 12 and the back plate 9 are used in coordination to clamp and support the documents of different sizes.

[0035] When it is necessary to adjust the clamping support angle of the document, the staff rotates the back plate 9 so that the back plate 9 drives the movable column 8 and the gear 5 to rotate with the rotating shaft 4 as the center. At the same time, the back plate 9 drives the document to rotate with the rotating shaft 4 as the center. When the back plate 9 drives the document to rotate and move to a suitable display angle, the staff rotates the screw 6 so that the screw 6 drives the tooth plate 7 to rotate and move on the inner surface of the frame 3 to engage with the gear 5, thereby limiting the back plate 9 and completing the adjustment of the document display angle. The device is simple to operate and easy to adjust and use, thereby meeting the customer's usage needs.
