[0023] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example:

[0025] Reference Figure 1 to Figure 5 The device is an adjustable sitting posture corrector, comprising a housing 2, which is detachably mounted on the side wall of a desk 1, a plurality of connection holes 11 are provided on the top of the housing 2, and bolts are passed through the connection holes 11 to connect with the desk 1 during installation, a connecting rod 3 is rotatably provided on the housing 2, a bearing 5 is provided in the housing 2, a shaft 6 is provided on the bearing 5, the shaft 6 passes through the side wall of the housing 2 and is fixedly connected with the connecting rod 3. This arrangement can effectively rotate the shaft 6 in the housing 2 through the bearing 5, and drive the connecting rod 3 fixedly sleeved on the shaft 6 to rotate, so that students can use and store the eye protection frame 4 conveniently. The top of the connecting rod 3 is adjustable and provided with an eye protection frame 4. A section of the eye protection frame 4 away from the connecting rod 3 is horizontally placed above the desk 1. A connecting hole 11 is provided at the top of the connecting rod 3. The end of the eye protection frame 4 is slidably inserted into the connecting hole 11. An adjustment slot 12 is provided on the side wall of the eye protection frame 4 extending into the connecting rod 3. An adjustment bolt 13 is provided on the side wall of the connecting rod 3. The adjustment bolt 13 is threaded through the side wall of the connecting rod 3 and abuts against the adjustment slot 12. This arrangement can effectively adjust the height of the eye protection frame 4 by abutting the adjusting bolt 13 with the adjustment slot 12 at different positions. The device also includes a placement bar 17, which is fixed on the side wall of the desk 1.
