[0002] Backpack users carry weight on their shoulders and back, which is more powerful than other methods, and their hands are more free, making it easier to carry for a long time. As a result, its uses are becoming more and more widespread.
[0003] Most mainstream buckles on the market adopt a fixed square or rectangular structure, lacking adjustable angle and tilt design. This rigid structure causes obvious discomfort to users with broad shoulders and has the following defects: 1. Because the buckle cannot adapt to the shoulder curve, the backpack slides downward, increasing the swaying amplitude during walking; 2. The pressure is concentrated at the shoulder and neck connection, which cannot effectively distribute the load. Long-term use can easily cause muscle strain. Considering these imperfections of the buckle, it may affect the development of children's back and spine. Utility Model Content
