Referring to fig. 1-6, a quick release zipper comprises a fastener tape 1, a slider 2, a hook 3 and a pull tab 4, wherein the fastener tape 1 comprises a first cloth tape 11, a second cloth tape 12, a plurality of fastener elements 13, a first stop block 14, a second stop block 15, a latch 16 and a quick release member 17, the plurality of fastener elements 13 are respectively arranged on opposite side edges of the first cloth tape 11 and the second cloth tape 12, the first stop block 14 and the second stop block 15 are respectively arranged at two ends of the first cloth tape 11, the latch 16 and the quick release member 17 are respectively arranged at two ends of the second cloth tape 12, the quick release member 17 and the first stop block 14 are oppositely arranged, quick release notch 171 is respectively arranged at the upper side and the lower side of the quick release member 17, the slider 2 is arranged on the fastener tape 1, the hook 3 is arranged on the slider 2, the pull tab 4 is connected with the hook 3, the first stop block 14 and the quick release notch 171 are respectively arranged at the upper side wing plate 21 and the lower wing plate 21 are respectively arranged at the two ends of the second cloth tape 12, and the quick release notch 171 is just pressed from the upper wing plate 21 and the lower wing plate 21.

Specifically, when the zipper needs to be quickly pulled open, one side of the dental chain belt 1 is pulled with force to enable the slider 2 to slide towards one end of the dental chain belt 1 until the hook 3 is pressed against the positioning stop block 141, at this time, the upper flank plate 21 and the lower flank plate 22 are just opposite to the quick release notch 171, and the upper flank plate 21 and the lower flank plate 22 continuously pull one side of the dental chain belt 1 with force, so that the slider 2 is separated from the second cloth belt 12, thereby achieving the purpose of quickly pulling the zipper, realizing the function of releasing the zipper without pulling the slider 2 back to the initial end, and greatly simplifying the operation steps of the zipper.

The quick release notch 171 is provided with a guide curved surface 1711 for guiding the upper side wing plate 21 and the lower side wing plate 22, and the upper side wing plate 21 and the lower side wing plate 22 can more easily enter the quick release notch 171 through the guide curved surface 1711.

A first limiting device 5 is arranged between the bolt 16 and the second stop block 15, and the first limiting device 5 is used for preventing the first cloth belt 11 and the second cloth belt 12 from moving in opposite directions. The first limiting device 5 includes a first limiting groove 51 and a first limiting projection 52, the first limiting groove 51 is disposed on a side wall of the latch 16, the first limiting projection 52 is disposed on the second stop 15, and specifically, when the zipper is closed, the first limiting projection 52 is clamped into the first limiting groove 51.

The quick release member 17 and the first stop block 14 are provided with a second limiting device 6 therebetween, the second limiting device 6 is used for preventing the first cloth belt 11 and the second cloth belt 12 from moving in opposite directions, and the limiting directions of the first limiting device 5 and the second limiting device 6 are just opposite.
