[0002] A student desk is a piece of furniture specifically designed for students to study. Its core function is to provide a suitable surface for students to engage in writing, reading, and drawing activities. The size of the desktop is usually large enough to accommodate books, notebooks, and stationery, while also providing sufficient support space for students' arms so that they can comfortably perform writing and other tasks.

[0003] A search revealed Chinese patent publication number CN111358183A, which discloses a student desk, including a desk box, two legs for supporting the desk box, and a tabletop mounted on the desk box. The legs include support frames with height cylinders fixedly connected to them. The upper back of the tabletop is connected to the desk box via a tilting cylinder. A cleaning device is located on the left side of the tabletop. A table hole is located on the surface of the tabletop near the rear, housing an anti-myopia sensor. A controller is located on the side of the desk box, containing a memory storage module and a data processing module. Students can adjust the height and tilt angle to their preferred height and angle, and the controller can automatically adjust or select different heights and tilt angles according to different learning needs. This helps remind students to maintain correct posture, effectively preventing myopia and hunchback. Daily cleaning of the desktop also helps maintain hygiene. However, the limited usable area of ​​the student desk necessitates stacking open books, leading to inconvenience and a lack of flexibility during use. Utility Model Content
