[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional multifunctional writing boards, most of them have relatively simple functions during use. Moreover, students often need to use various learning supplies, such as writing boards, bookshelves, desk lamps, etc. However, these supplies are usually designed separately, which takes up a large space when used, and are not easy to carry and organize, so it is inconvenient to achieve the problem of convenience and practicality. The multifunctional writing board is provided with an adjustment structure and a plug-in structure. When the multifunctional writing table is in use, the books can be clamped and fixed on the top of the bookshelf by the clamping structure, and then the height of the bookshelf can be adjusted by the lifting structure. At the same time, the lighting structure can be used to adjust the lighting of the writing table. In addition, the backrest is fixedly installed on the side wall of the writing table by the plug-in structure. In addition, the height of the backrest can be adjusted quickly and conveniently by the adjustment structure, so as to achieve the effect of convenience and practicality.

[0014] 2. When the multifunctional writing desk is in use, first place the books on the support plate of the bookshelf, and then automatically adjust according to the thickness of the books through the elastic clamps. Since the elastic clamps have certain elasticity and toughness, they can adapt to books of different sizes and clamp the surface of the books through slight bending or deformation. At the same time, the design of the clamping assembly ensures the stability and safety of books or other items on the bookshelf. The clamping action of the elastic clamps prevents the books from sliding or tilting. Then, when the height of the bookshelf needs to be adjusted, first, manually lift and adjust the lifting and adjusting block to a suitable position through the multi-section adjustment bracket, and then insert the locking bolt into the lifting and adjusting block. Subsequently, the locking nut and one end of the locking bolt are tightened and installed. Since the plastic clamps on both sides of the lifting and adjusting block have certain elasticity and toughness, as the locking nut is tightened and installed, the plastic clamps are clamped against the side walls of the multi-section adjustment bracket, thereby achieving the effect of height adjustment.

[0015] 3. When the height of the backrest needs to be adjusted, first manually pull the adjusting piece upwards. The user presses the pressing piece to rotate the pressing piece relative to the mounting shaft and compress the hinge spring. At this time, the contact card will disengage from the contact tooth groove of the adjusting piece, and the adjusting piece can slide in the support piece. When the adjusting piece slides to the desired position, the user releases the pressing piece. Due to the reset force of the hinge spring, the pressing piece will quickly return to the initial position and drive the contact card to re-enter the contact tooth groove of the adjusting piece to lock the position of the adjusting piece. The user can repeat the above process as needed to achieve multiple position adjustments of the adjusting piece, thereby achieving the purpose of quickly and conveniently adjusting the height of the backrest, so that it is suitable for people of different heights.
