Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper upper and lower stop mold. Background Art

[0002] The existing zipper bottom stop is easily deformed by pressure due to its arc-shaped bulging design on both sides, so that the two zipper bottom stops cannot fit together after deformation, causing the entire zipper to be damaged and unusable. Therefore, it is necessary to provide a zipper bottom stop design with higher strength.
