A zipper is a connector that relies on continuous rows of fasteners to make objects merge or separate. It is now widely used in clothing, bags, tents, etc.
The definition of the zipper:
1 A fastener consisting of two rows of metal or plastic teeth on each of the belts for connecting the edges of the opening (such as clothes or pockets), and a sliding member for pulling the two rows of teeth into the interlocking position to close the opening;
2 A chain attached to something (as an object that is lifted or dropped) to tighten, stabilize, or guide the object.
The zipper is composed of a chain element, a slider, a top and bottom stop (front and rear code) or a locking member. The chain element is the key part, which directly determines the side pull strength of the zipper. Generally, the zipper has two chain belts, each of which has a row of fastener elements, and the two rows of fastener elements are staggered. The sliders are clamped on both sides of the fasteners, and the fastener elements on both sides can be engaged or disengaged by the sliders.
