Zusammenfassung: | The utility model discloses a zip fastener with no meter tooth exposed on surface after a zip fastener is zipped. The zip fastener is characterized in that when meter teeth are arranged on a yarn belt, a meter head is arranged on the left end of the facade of the yarn belt; a flat opening on the lower half sheet of the head is as high as the height of a head opening, and an edge is inwards folded on the top. After the zip fastener is zipped, the meter teeth drive the yarn belt to fold inwards to achieve the effect that the meter teeth are not exposed on the surface. |
