The specific embodiment

As shown in Figure 2, the utility model Elastic zipper 2 comprises zipper unit 21 and two and zipper unit 21 equal lengths and be symmetrically fixed on the cloth unit 22 of its dual-side.

Zipper unit 21 has two other ends that are the chain 211 that zigzag tooth connects, the riveting knot part 212 that is cemented in two chains, 211 1 ends and are combined in chain 211 for drawing back or the portion of holding 213 of closed sprocket.

Cloth unit 22 have reverse outer side edges 221, and the fixed inner side edge 222 of zipper unit 21 and between inner side edge 222 and outer side edges 221 tool stretch flexible flexible position 223.

During use, as Fig. 3, shown in Figure 4, the outer side edges 121 of the utility model cloth unit 22 is spliced relatively in shoes 3, clothing, suitcase, knapsacks etc. need to install the shoes 3 of slide fastener, the opening part of clothing or other article, and utilize sewing type, with the outer side edges 221 of cloth of the present utility model unit 22 fixed with the open side edges of its article be one, just can utilize hand to hold the portion of holding 213 of zipper unit 21, pulling back and forth, two sprockets 214 of its two-phase toe joint are separated or butt joint, in the hope of reaching the convenient clothing that draws back fast or seal, the purpose of openings such as article and effect.
