[0024] In this embodiment:

[0025] When the zipper is in use, the two chain teeth 2 can be closed by pulling the slider 3, and the movement of the slider 3 can be limited by the action of the contact head 8 and the baffle plate 9. When the chain needs to be opened quickly, it is only necessary to press the pressing piece 10 to push the contact head 8 to retract into the installation tube 5 through the pressing piece 10. In this way, the slider 3 can be pulled continuously. Since the chain teeth 2 are arranged on one side of the side band 102 higher than the contact head 8, after the slider 3 passes over the contact head 8, it is only necessary to pull one side of the side band 102. Without the limitation of the slider 3, the two chain teeth 2 on the side band 101 and the side band 2 102 will separate, completing the chain opening operation of the zipper. The operation is simple and convenient. Similarly, when the zipper needs to be closed again, the slider 3 is pulled downward. Under the action of the inclined surface on one side of the baffle plate 9, the contact head 8 can be pushed to retract, and then the slider 3 can be easily returned to its original state after passing over the contact head 8.

[0026] When the side of the slider 3 is deformed and cannot be pulled, the pushing block 15 on one side of the slider 3 can be pulled to drive the card block 16 to move and disengage from the card slot 14, so that the upper pull member 301 and the lower pull member 302 can be disengaged, thereby removing the slider 3 from the two chain tooth strips 2, and then pulling the side band 1 101 or the side band 2 102 can quickly disengage the two chain tooth strips 2, completing the quick chain opening operation of the zipper.

[0027] Compared with the related art, the quick-opening zipper provided by the utility model has the following beneficial effects:

[0028] By installing the cylinder 5, the plugging head 6, the first return spring 7, the contact head 8, the connecting plate 4, the pressing piece 10, the baffle 9 and the second return spring 11, the different positions of the pull head 3 can be quickly set, and then the length of the two chain teeth 2 can be set to complete the fast opening of the zipper, which is simple and convenient to operate;

[0029] By setting the installation groove 13, the card slot 14, the pushing block 15, the card block 16 and the reinforcing spring 18, the upper pull member 301 and the lower pull member 302 can be quickly separated, and then the chain can be quickly opened when the pull head 3 is damaged, thereby improving the safety of the zipper.
