Technical Field

[0001] The utility model relates to the technical field of zipper heads, in particular to a zipper head that can be quickly replaced. Background Art

[0002] Zippers are widely used and are generally used in bags, clothing, and shoes. Zippers include a cloth tape with teeth that bite each other and a zipper head. The cloth tape is fixed to the product, and the zipper is opened and closed by pulling the slider.

[0003] The zipper head will be worn and damaged due to long-term pulling. The existing zipper head needs to be replaced in a store. When the zipper head is replaced by yourself, it is easy to damage the structure of the zipper and make the zipper head lose its function.

[0004] The authorization announcement number CN209528072U discloses a replaceable zipper head, which is designed to be split. When replacing the zipper head, the zipper body is placed between the upper and lower plates, and then the upper and lower plates are snapped together to achieve the replacement of the zipper head. The above technical solution still has some shortcomings during use. Since the upper plate and the lower plate are split structures, they need to be re-aligned and snapped together when replaced and re-fastened. The alignment is inconvenient. If the alignment is not accurate, it will affect the accuracy of the snapping. Secondly, when snapping, two hands are required to operate, and both hands are aligned with the upper plate and the lower plate respectively, and there is no free hand to adjust the zipper or the cloth belt, so it is also inconvenient to operate.
