AI Technical Summary

Technical Problem

When using zipper pulls with different designs, the insert rod of the existing zipper pull can easily get caught on the claw of the zipper pull, resulting in reduced operability.

Method used

A release insert is designed, in which the insert bar and the seat bar correspond to the pull head with a stop mechanism. The insert bar has a bulge and an inclined surface. The bulge is close to or in contact with the claw of the pull head, and the main body of the insert bar corresponds to the upper and lower wing plates of the pull head. The inclined surface is inclined downward to prevent the insert bar from getting hooked.

Benefits of technology

Even with different pull heads, the insert can be smoothly inserted and removed, avoiding snagging and improving operability.
