This utility model belongs to the field of zipper technology, specifically a zipper tooth anti-detachment reinforcement structure, including a zipper tape; a zipper tooth body is slidably connected to the middle of the zipper tape; an extension plate is fixedly connected to the bottom plate of the zipper tooth body; two sleeves are fixedly connected to both sides of the extension plate; a spring is fixedly connected to the middle of the sleeve; a lever is fixedly connected to one end of the spring; firstly, the zipper tooth body is pulled, and the zipper tooth body slides on the zipper tape. During this process, the spreading plate will extend the lining fabric near the zipper tooth body, reducing the phenomenon of wrinkles in the lining fabric near the zipper tooth body when it gets close, which would cause the zipper tooth body to clamp the lining fabric with the zipper tape, causing the zipper tooth body to get stuck. When the zipper tooth body moves to the end of the zipper tape, the spreading plate will be obstructed by the end and move backward, the lever slides in the sleeve, and the spring is compressed. This does not affect the tight connection between the zipper tooth body and the zipper tape.
