AI Technical Summary
Traditional plastic backpacks have fixed-length straps that cannot be adjusted according to the user's height, body shape, or carrying needs, resulting in discomfort and looseness, which affects convenience.
An adjustable-strap plastic basket was designed. By setting a reinforcing plastic plate, studs and threaded sleeves on the main body of the basket, combined with the snap-fit structure of hooks and through holes, the length of the straps can be flexibly adjusted. A rigid sleeve protects the through hole area to prevent loosening.
The carrying strap length is flexibly adjustable, ensuring consistent length after each adjustment, preventing loosening, improving ease of use and stability, and extending the lifespan of the basket.
