A handle 26 is provided on the outer rear side of the gear frame 25, and the handle 26 is slidably connected to the fixed frame 103.

[0071] Reference Figure 1 , Figure 7 and Figure 8The fixing mechanism 3 includes a limit shell 31, a second guide rod 32, a second spring 33 and a clamping block 34. The limit shell 31 is welded in the middle of the left and right sides of the lower side of the fixed frame 103. Two second guide rods 32 are welded in the limit shell 31. A clamping block 34 is slidably provided between the two second guide rods 32 on the same side. The clamping block 34 is in contact with the adjacent tooth frame 25. The clamping block 34 can clamp the tooth frame 25 when it moves upward. The second spring 33 is wound around the lower part of the second guide rod 32. The two ends of the second spring 33 are respectively connected to the clamping block 34 and the limit shell 31.

[0072] Initially, the second spring 33 is in a compressed state. When the student needs to use the desk, the student first puts the desk in the designated position, then rotates the nut 53, the nut 53 moves inward and separates from the screw 52, ​​then pulls the screw 52 outward to separate the screw 52 from the table frame 102, and then moves the fixing frame 103 up and down, driving the table frame 102, the first table board 105 and the second table board 106 to move up and down. When the first table board 105 and the second table board 106 move to a suitable height, stop moving the fixing frame 103, and then put the screw 52 back in place, so that the screw 52 passes through the adjacent table frames 102, and then reverses the nut 53 to reset it, so that the position of the fixing frame 103 can be stabilized, and then the first table board 105 can be fixed. 05 and the height of the second table board 106, and then the student can pull the handle 26 forward to drive the tooth frame 25 to move forward, the tooth frame 25 drives the second gear 23 to rotate, thereby driving the second shaft 24 to rotate, the second shaft 24 drives the first gear 22 to rotate, the first gear 22 drives the rack 21 to move upward, thereby driving the bookshelf 104 to move upward, the bookshelf 104 will squeeze the second table board 106 to rotate upward and open, when the block 34 is aligned with the groove, the second spring 33 returns to its original state, driving the block 34 to move upward, so that the block 34 clamps the tooth frame 25, and then the handle 26 can be released, and then the lifting plate 11 is pressed downward, the first spring 13 is stretched, and then the books are neatly placed in the bookshelf 104, and the books at the bottom will press the lifting plate When the student does not need to use the desk, he takes out the schoolbag and then presses the card block 34 downwards, so that the lifting board 11 can be pressed tightly against the book shelf 104. The second spring 33 is compressed, so that the block 34 releases the tooth frame 25. At this time, under the action of gravity, the bookshelf 104 will move downward and reset, driving the rack 21 to move downward and reset. The rack 21 drives the first gear 22 to reverse, thereby driving the second shaft 24 and the second gear 23 to reverse, and the second gear 23 drives the tooth frame 25 and the handle 26 to move backward and reset. At this time, the tooth frame 25 will block the top of the block 34. The student can release the block 34 and then rotate the second table board 106 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 the student to access books. When the student takes out all the books, the first spring 13 will completely return to its original state, and can drive the lifting plate 11 to move upward and completely reset.

[0073] Example 2

[0074] Based on Example 1, Figure 1 , Fig. 9 and Fig.10 , also includes a protection mechanism 4, the protection mechanism 4 includes a blocking block 41, a protection plate 42 and a torsion spring 43, the left and right front parts of the fixed frame 103 are slidably provided with blocking blocks 41, the tooth frame 25 moves forward and contacts with the blocking blocks 41, the lower rear side of the first table board 105 is rotatably provided with a protection plate 42, the protection plate 42 blocks the front side of the bookshelf 104, the blocking blocks 41 block the front side of the protection plate 42, so that the books can be protected, and torsion springs 43 are provided between the left and right sides of the protection plate 42 and the first table board 105.

[0075] Initially, the torsion spring 43 is in a deformed state, and the protection plate 42 blocks the front side of the bookshelf 104. When the student puts the pen into the fixed frame 103, the pen tip can be prevented from scribbling on the book. When the tooth frame 25 moves forward, the bookshelf 104 will move upward. When the tooth frame 25 contacts the blocking block 41, it will squeeze the blocking block 41 to move outward, so that the blocking block 41 no longer blocks the protection plate 42. The torsion spring 43 returns to its original state, driving the protection plate 42 to rotate upward and open. At this time, the student can put the schoolbag into the fixed frame 103. When the tooth frame 25 moves backward and resets, it will separate from the blocking block 41, and the bookshelf 104 will move downward and reset. At this time, the student can rotate the protection plate 42 downward and close it. The torsion spring 43 is deformed, so that the protection plate 42 blocks the front side of the bookshelf 104 again, and then the blocking block 41 is pushed inward and reset, so that the blocking block 41 blocks the front side of the protection plate 42 again.

[0076] Reference Figure 1 and Fig.12 , also includes a moving mechanism 6, the moving mechanism 6 includes a moving wheel 61, an axle 62, an anti-skid pad 63 and a pushing block 64, the front and rear sides of the lower inner side of the table leg 101 are slidably provided with axles 62, and the axles 62 are rotatably provided with moving wheels 61, and the moving wheels 61 can contact the ground when moving downward, so that they can roll on the ground, which is convenient for students to move the desk, the front and rear sides of the bottom of the table leg 101 are provided with anti-skid pads 63, and the front and rear sides of the lower part of the table leg 101 are slidably provided with pushing blocks 64, and the pushing blocks 64 can contact the axle 62 when moving inward.

[0077] When the desk is placed in the designated position, the anti-skid pad 63 can play an anti-skid role to prevent the desk from moving at will. When the student needs to move the desk, first lift the desk slightly, and then push the pushing block 64 inward. The pushing block 64 will squeeze the wheel axle 62 to move downward, driving the moving wheel 61 to move downward. At this time, the pushing block 64 can block the top of the wheel axle 62, and then put down the desk so that the moving wheels 61 are in contact with the ground. Then the desk can be pushed to move, and the moving wheels 61 can roll on the ground. When the desk is moved to the appropriate position, the pushing block 64 is moved outward and reset so that the pushing block 64 no longer blocks the top of the wheel axle 62. At this time, under the action of gravity, the entire desk will move downward, causing the wheel axle 62 and the moving wheel 61 to move upward relative to the table legs 101 and reset, so that the anti-skid pad 63 can contact the ground again.
