Abstract
【Item Uses】 This invention is a chain tooth used in conjunction with a zipper mechanism. 【Design Description】 The chain teeth of this creation include an upper tooth and a lower tooth that are stacked on top of each other. The upper and lower teeth are connected at their middle ends and form two opposing clamping grooves between them. The upper tooth is generally heart-shaped and a polygonal gemstone is set on its upper surface. The lower tooth has two streamlined concave arcs. The upper and lower teeth are symmetrical with a center line, and the center lines of the upper and lower teeth intersect each other perpendicularly. When the chain teeth are formed on a strip of fabric, the upper tooth is used to present the beauty of the chain teeth.
