[0023] See also Figure 1 and Figure 2As shown, the present embodiment discloses a classroom book fixing bracket, comprising a support assembly and a lifting assembly, the lifting assembly being used to adjust the height of the support assembly, and the support assembly being used to place books. Specifically, the lifting assembly comprises a support rod 7, the lower part of the support rod 7 is threadedly connected with a rotating disk 8, and a plurality of support feet 81 are evenly hinged on the circumference of the rotating disk 8. In this scheme, three support feet 81 are arranged, and a limiting disk 71 is fixed at the lower end of the support rod 7. When the rotating disk 8 rises to the highest point, the lower end of the support foot 81 is higher than the limiting disk 71, and the limiting disk 71 can be supported on the ground as a supporting chassis; three limiting slots are provided on the circumference of the limiting disk 71 to cooperate with the three support feet 81. When the rotating disk 8 descends, the lower end of the support foot 81 is lower than the limiting disk 71, and the three support feet 81 are supported on the ground, and each support foot 81 is inserted in a limiting slot to limit its movement. In order to improve stability, the bottom end of each support foot 81 is hinged with an anti-slip pad 82 to increase the friction between the support foot 81 and the ground.
[0024] The supporting assembly is fixed to the upper end of the lifting assembly. Specifically, the supporting assembly includes a placing plate 2 for placing books. The top bolt of the supporting rod 7 is fixed with a fixing plate 1. The fixing plate 1 is rotatably connected to the placing plate 2. A number of positioning strips 11 are evenly distributed on the fixing plate 1. The side of the placing plate 2 close to the positioning strip 11 is rotatably connected with a supporting plate 6. The free end of the supporting plate 6 can be abutted against the positioning strip 11. By changing the abutting position of the supporting plate 6, the rotation angle of the placing plate 2 can be changed to adjust the tilt angle of the book. A book stopper 22 is also fixed to the bottom end of the placing plate 2. The book stopper 22 can block the lower end of the book to prevent the book from sliding when tilted, thereby ensuring the stability of the book.
[0025] The placing plate 2 is also provided with a book pressing component. Specifically, a through slot 21 is opened in the middle of the placing plate 2, and an adjusting rod 3 is vertically slidably arranged on the upper side of the through slot 21. The adjusting rod 3 passes through the through slot 21 and is bolted with a cross bar 32 at one end. The two ends of the cross bar 32 are respectively hinged with oblique pressure strips 321, and a magnetic patch 322 is fixed to the free end of the oblique pressure strip 321. Pull plates 4 are respectively arranged on both sides of the placing plate 2, and the pull plates 4 are connected to the placing plate 2 through a telescopic grille 5.

[0026] Specific implementation process:
[0027] Before class, adjust the height of the bracket first. By turning the rotating disk 8, the three supporting feet 81 are lowered to a suitable height, and then the supporting feet 81 are snapped into the limit slots. Then, the positions of the pull plate 4 and the adjusting rod 3 are adjusted according to the size of the book, so that the two sides of the book are placed on the two pull plates 4, and the horizontal bar 32 above the adjusting rod 3 is higher than the book, so that the diagonal pressure rod can press down a corner of the book. After the above adjustments are completed, take the bracket to the podium, put it in a suitable position, and then place the book between the two pull plates 4. After turning to the corresponding page number, use the diagonal pressure strip 321 to press down the two upper diagonal corners of the book. Finally, adjust the book to a suitable inclination angle, and then you can start teaching.
[0028] After the class is over, the bracket is taken back to the office for use in the next class; if the bracket is not needed, the support plate 6 can be lowered to make the placement plate 2 parallel to the fixed plate 1, and the two pull plates 4 can be folded together, and the adjustment rod 3 can be slid to the bottom to shrink the support assembly to the minimum to reduce the space occupied, and then the rotating disk 8 can be turned to make the three support feet 81 rise to the highest point, so that the height of the bracket becomes the shortest, so as to reduce the storage space occupied.
