[0002] Backpack is a general term for backpacks carried on shoulders. According to the different uses of backpacks, they are divided into computer backpacks, sports backpacks, fashion backpacks, school backpacks and drawstring bags, military backpacks, mountaineering bags, etc. According to the different materials, they can be divided into canvas bags, Oxford cloth bags, and nylon cloth bags.

[0003] In order to ensure the healthy growth of children in the prior art, a spine-protecting and hunchback-preventing backpack has been developed, which can effectively protect the child's back and prevent hunchback. For example, the patent publication number is CN217243075U. This patent can use the elastic force of the elastic straps to pull the backpack body to squeeze the user's waist, and push the user's waist forward through the rubber pad, thereby straightening the user's back and preventing the user from hunching. However, since the elastic straps cannot be adjusted in size, when the user is relatively small or obese, the straps may not be tied tightly or may be too tight, causing discomfort to the user. The applicability has certain shortcomings. In view of this, we propose a spine-protecting and hunchback-preventing backpack. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a spine-protecting and hunchback-proof backpack, which can solve the problem that the straps cannot be adjusted, resulting in certain deficiencies in applicability.
