Zippers (zippers), which are connectors for uniting or separating articles by means of a continuous arrangement of zipper teeth, are now widely used in clothing, bags, tents, etc. The zipper is composed of zipper teeth, a pull head, an upper stop and a lower stop (a front stop and a rear stop) or a locking piece and the like. The zipper teeth are key parts, and directly determine the side pull strength of the zipper. Generally, a zipper has two zipper tapes, each zipper tape has a row of zipper teeth, and the two rows of zipper teeth are arranged in a staggered manner. The zipper teeth at the two sides are clamped by the pull head, and the zipper teeth at the two sides can be meshed or separated by sliding the pull tab.
Conventional slide fasteners generally include two panels made of fabric, two zipper teeth respectively coupled to inner edges of the two zipper panels, and a slider (slider) movably coupled between the zipper teeth of the two zipper panels so as to drive the zipper teeth of the two zipper panels together or apart when the slider moves. However, for some large-sized zippers, the zipper joint path is long, and when the zipper needs to be released, the zipper needs to be pulled to the starting position for complete release, so that the operation is complicated, and the speed and efficiency for releasing the zipper joint are low; in addition, in order to secure the coupling strength of the slide fastener having a long path, the teeth are generally increased, but the friction force between the large teeth is large, so that the feeling of jerkiness is strong when the slide fastener is pulled, and the convenience of the pulling is affected.
