Description

technical field [0001] The invention relates to the technical field of hunchback prevention devices, in particular to a hunchback prevention device for elementary school students. Background technique [0002] At present, more and more attention has been paid to corrective and preventive products for primary school children's poor development, including the prevention of myopia and hunchback. Users in the younger age group have poor self-control, and it is easy to develop bad reading and writing postures without the supervision of parents or others. . Reading and writing at a close distance at a desk for a long time can easily induce hunchback and myopia.
