Description

Technical field: [0001] The invention relates to a knapsack correction device suitable for use by students and long-term office workers. Background technique: [0002] At present, the myopia correction method used by students is basically wearing myopia glasses, and acquired myopia is mainly caused by sitting and reading for a long time, especially incorrect posture, and keeping too close to the book for a long time, and maintaining a posture. In addition, incorrect sitting posture for a long time can easily lead to curvature and deformation of the spine. However, currently commercially available sitting posture correctors for students are generally designed on the desktop, which affects the placement and writing of desktop objects. Some use the alarm type, but the sound will be irritating after listening to it for a long time, which will affect the learning mood. Although the commercially available back back good can correct the posture, when correcting the sitting postur...
