The zipper teeth are key parts, and directly determine the side pull strength of the zipper. Generally, a zipper has two fastener tapes, each fastener tape has a row of teeth, and the two rows of 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.

A conventional zipper generally comprises two zipper strips made of cloth, two zipper teeth respectively coupled to inner edges of the zipper strips, and a slider (zipper head) movably coupled between the zipper teeth of the two zipper strips, wherein the zipper teeth of the two zipper strips are driven to be coupled together or separated from each other 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.
