Background

The zipper is a common article in our daily life and is widely applied to common articles such as clothes, bags and the like. The zipper mainly comprises a pair of cloth belts, a tooth chain belt fixedly arranged at the inner side edge of each cloth belt and a zipper head meshed on the tooth chain belt, wherein the zipper head comprises a zipper head main body and a pulling piece, and a user pulls the zipper head through holding the pulling piece to enable the pair of tooth chain belts to be meshed or separated, so that the zipper is correspondingly closed or opened.

At present, a pull tab on a zipper head is required to have various designs besides being used as an operation part for pulling the zipper head, so that articles such as clothes, bags and the like on which the zipper is installed are more diversified; based on this, a replaceable cord member (typically a nylon cord) is mounted on the pull tab. In the prior art, in some zipper heads, nylon ropes are directly sleeved on a metal pull-tab main body in a penetrating way; however, this tab construction, while simple, makes length adjustment of the nylon rope after installation difficult, inconvenient to handle, and difficult to align the two ends of the nylon rope. There are also some sliders in which a pull tab is provided with an auxiliary means for fixing a nylon cord; for example, japanese patent publication No. 3544288B2 discloses a slider in which a nylon rope is held and fixed by an auxiliary tool, and the nylon rope can be fixed well, but after the nylon rope is attached, the slider is hard to slide in the auxiliary tool, so that the length of the attached nylon rope cannot be changed.

In summary, in the pull tab of current zipper head, the nylon rope does not possess length adjustment's function after the installation, and the nylon rope when installing hardly guarantees that its both ends can align.
