[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:

[0021] Reference Figures 1 to 3 As shown, the utility model discloses an intelligent anti-myopia desk, comprising a desk 1, columns 2 are provided at both ends of the upper surface of the desk 1, mounting grooves are provided at corresponding positions of the inner walls of the two columns 2, mounting beams 4 are provided in the mounting grooves, slide grooves 12 are provided on the mounting beams 4, movable blocks 5 are slidably provided in the slide grooves 12, connecting rods 6 are provided at the front end of the movable blocks 5, and limiters 7 are provided at the end of the connecting rods 6. When in use, the limiters 7 can be used to limit the position of the user's head to prevent the user's head from being too close to the desktop, thereby ensuring the eye distance and preventing myopia.

[0022] Furthermore, the mounting beam 4 can move in the mounting groove through an adjusting mechanism. The adjusting mechanism includes a crossbeam 3 arranged in the mounting groove. A pneumatic rod 9 is provided at the lower end of the crossbeam 3. The pneumatic rod 9 is driven by a cylinder 10 installed on the desk 1. The cylinder 10 is controlled by a starter 11.
