[0024] In the present invention, in order to enable the placement plate 7 to be lifted and lowered stably in the vertical direction, the material of the movable shaft 6 is set to stainless steel, thereby effectively improving the service life of the movable shaft 6. The two groups of movable shafts 6 on the left and the two groups of movable shafts 6 on the right are symmetrical with each other with the longitudinal center line of the placement plate 7 as the center, so that the movable shafts 6 on the left and right sides can limit the placement plate 7 more evenly, thereby effectively improving the stability of the movement of the placement plate 7.

[0027] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0028] The working principle of the utility model is:

[0029] S1. Unlock the moving rod 9 and rotate the driving wheel 18 clockwise. The driving wheel 18 simultaneously drives the fixing ring 14, the limiting ring 17, the rotating shaft 13 and the locking block 15 to rotate clockwise around the center line of the rotating shaft 13. The locking block 15 is separated from the locking groove 10 to unlock the moving rod 9, thereby unlocking the placement plate 7, the linkage plate 8 and the moving shaft 6. The fixing ring 14 rotates with the rotation of the rotating shaft 13, so that the fixing ring 14 applies a force to the bottom end of the torsion spring 16. When the locking block 15 is separated from the locking groove 10, the rotating shaft 13 and the locking block 15 have a tendency to rotate counterclockwise.

[0030] S2, lifting and lowering the placement plate 7. When the locking block 15 is separated from the locking groove 10 and the locking of the moving rod 9, the linkage plate 8, the placement plate 7 and the moving shaft 6 is released, the linkage plate 8 can drive the moving shaft 6, the moving rod 9 and the placement plate 7 to move upward relative to the table top 1 and the limiting cylinder 5 under the elastic action of the spring 12, so that the placement plate 7 can be raised. When the height of the placement plate 7 needs to be lowered, it is only necessary to manually press the placement plate 7 downward;

[0031] S3. Lock the placement plate 7. When the height of the placement plate 7 is adjusted, align the locking block 15 with the nearest locking groove 10, and then release the driving wheel 18. Under the elastic action of the torsion spring 16, the fixing ring 14 can drive the rotating shaft 13 and the locking block 15 to rotate counterclockwise, so that the locking block 15 and the locking groove 10 are adapted to lock the movable rod 9, so that the movable rod 9, the placement plate 7, the linkage plate 8 and the movable shaft 6 are all fixed relative to the table top 1, and under the elastic action of the torsion spring 16, the locking block 15 can be tightly adapted to the locking groove 10 to lock the movable rod 9.

[0032] In summary, the Chinese teaching desk can conveniently and flexibly separate the locking block 15 from the locking groove 10 by manually rotating the driving wheel 18 clockwise, thereby conveniently releasing the lock on the moving rod 9 and the placement plate 7, so that the height of the placement plate 7 can be flexibly adjusted, and only the driving wheel 18 needs to be loosened, and the locking block 15 can tightly and effectively lock the moving rod 9 under the elastic action of the torsion spring 16, thereby more effectively improving the stability of the placement plate 7, and also improving the practicality of the Chinese teaching desk, by setting the limit cylinder 5 and the table board 1 to cooperate with each other to limit the position of the moving shaft 6 and the linkage plate 8, when the locking of the moving rod 9 and the linkage plate 8 is released, the linkage plate 8 and the moving shaft 6 The lifting and lowering motion in the vertical direction can be performed more smoothly, thereby effectively improving the stability of the movement of the placement plate 7, that is, the placement plate 7 can stably and effectively carry the teaching books, further improving the practicality of the Chinese teaching desk, and by setting the spring 12, an upward force is always applied to the linkage plate 8. When the lock of the moving rod 9 is released, the placement plate 7 and the moving shaft 6 can be flexibly moved upward automatically, thereby improving the flexibility of the use of the placement plate 7, and by setting the limit ring 17 to limit the position of the rotating shaft 13, the locking block 15 can be relatively smoothly rotated in the horizontal direction, so that the locking block 15 can lock the moving rod 9 more smoothly and effectively, thereby further improving the stability of the use of the placement plate 7.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0034] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
