When the student needs to take out the book, he can directly pull the book forward. At this time, the first spring 13 will slightly return to the original state, driving the lifting plate 11 to move slightly upward to reset. , so that other books can be pressed. When people need to put the books back on the bookshelf 104, they press the lifting plate 11 down again, and the first spring 13 is stretched again, so that the lifting plate 11 releases the books, and then the books can be put back. In the bookshelf 104, the lifting plate 11 is released again. Under the elastic force of the first spring 13, the lifting plate 11 can re-press the book. When the student does not need to use the desk, take out the schoolbag, and then press the card downward. Block 34, the second spring 33 is compressed, so that the blocking block 34 releases the tooth frame 25. At this time, under the action of gravity, the bookshelf 104 will move down to reset, driving the rack 21 to move down to reset, and the rack 21 drives the A gear 22 is reversed, thereby driving the second rotating shaft 24 and the second gear 23 to reverse, and the second gear 23 drives the gear frame 25 and the handle 26 to move back and reset. At this time, the gear frame 25 will block the top of the block 34, and the students The block 34 can be released, and then the second table board 106 can be turned forward to close it. When the student pulls the handle 26 forward again, the bookshelf 104 can be driven to move upward, which is convenient for students to access books. After all the books are taken out, the first spring 13 will be completely restored to its original state, which can drive the lifting plate 11 to move upward and completely reset.

Example 2

On the basis of Embodiment 1, referring to FIG. 1 , FIG. 9 and FIG. 10 , a protection mechanism 4 is also included. The protection mechanism 4 includes a blocking block 41 , a protection plate 42 and a torsion spring 43 . The left and right sides of the fixing frame 103 are The front part is slidably provided with a blocking block 41, and the tooth frame 25 will contact the blocking block 41 when moving forward.
