Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper puller with high self-locking force. Background Art

[0002] A zipper, also known as a zip fastener, is one of the ten great inventions that have facilitated people's lives in modern times. It is a fastener composed of a row of metal teeth or plastic teeth on each of two tapes, used to connect the edges of an opening (such as the edge of a piece of clothing or a bag opening). There is a sliding piece that can pull the two rows of teeth into an interlocked position to close the opening. It is sewn on clothes, pockets or leather bags and mainly consists of chain teeth, a puller, limit codes (front code and rear code) or locking parts.

[0003] Although there are many types of pullers with self-locking functions on the market at present, they are basically the same. The structures of the pullers with self-locking functions in the prior art are mostly composed of a puller body, a pull tab, a hook and a cap. The pull tab and the hook are two independent accessories. The self-locking function of the puller is realized by the hook. Since the self-locking is only achieved by a single hook hooking the zipper teeth, once the hook is damaged, it is extremely easy to cause poor self-locking function of the puller, resulting in a short service life of the self-locking puller.
