AI Technical Summary
Existing zipper inserts require different designs for right-insertion and left-insertion zipper pulls, leading to increased manufacturing costs, reduced productivity, and complicated quality management. Additionally, the insert bar and the claw of the zipper pull are prone to snagging, affecting sliding performance.
Design a detachable insert with a claw-through passage and a side step. The bottom surface of the claw-through passage is lower than the main body of the insert and the bottom surface of the claw-through passage is inclined forward to reduce interference between the claw and the insert. The side step extends to the top of the insert to accommodate the use of different types of pull heads.
This design allows both right-insertion and left-insertion type pull heads to share the same structure, reducing the hooking of the insertion bar and the pull head claw, improving sliding performance and production efficiency, and reducing manufacturing costs.
