Description

Technical Field

[0001] This utility model relates to the field of hook and loop fastener technology, and more specifically, to an adjustable hook and loop fastener for bags. Background Technology

[0002] There are many types of hook and loop fasteners that can be used in different scenarios. The most common type in the clothing and bag industry is nylon hook and loop fastener, which can achieve the function of connection and is simple to connect. It is usually used on bags and clothing. It has male and female sides. One side is a male side with soft fibers and the other side is a female side with hook and loop elastic fibers. When the male and female sides are interlocked, under a certain horizontal force, the elastic hook is straightened, releases from the loop and opens, and then returns to the original hook shape. It can be opened and closed repeatedly.

[0003] However, most existing hook and loop fasteners for bags are fixed structures and have uniform lengths, which means that users cannot adjust the extension length of the female and male hooks according to their own preferences during use, resulting in certain limitations in their use.

[0004] Furthermore, when hook and loop fasteners are connected to bags, they are mostly sewn together with thread, which means that when it is necessary to remove or replace the hook and loop fasteners, external tools are required, making the replacement process quite troublesome.
