[0002] Straps are widely used in the market. Among them, woven straps, elastic bands, etc. with a certain width are generally used in daily life such as backpacks, belts, luggage packing and fixing, and tent storage. At present, most of the straps on the market use plastic snap buttons with male and female snap buttons to connect the two ends of the strap or connect two straps, and a "day"-shaped adjustment buckle can be used to adjust the length of the strap so that users can adjust the strap to a suitable length. However, at present, for the existing plastic snap buttons, when adjusting the strap, at the position of the adjustment buckle, it is necessary to concentrate on moving and pulling the strap in the direction of adjusting the length. And when the length to be adjusted is large, it is necessary to repeatedly move and pull the strap, which is time-consuming and energy-consuming, and cannot meet the problem of rapid adjustment by users. Moreover, when the existing plastic snap buttons are fixed on the strap, it is necessary to pass the two ends of the strap through the male and female snap buttons respectively, and then fold them back and forth and use sewing to fix the male and female snap buttons of the plastic snap button. This fixing method is cumbersome, increases the assembly process, and is inconvenient for product assembly. Summary of the Invention
