[0002] In the luggage industry, zippers are often used as tools for controlling the opening or closing of openings. In traditional operations, the two tapes of the zipper need to be sewn to the luggage body respectively. Then, there is a snap connection for the opening and closing sides of the luggage. For example, a snap-type zipper structure disclosed in the Chinese patent document with the publication number CN209473758U includes a zipper body and a first adapter for connecting the zipper body. The zipper body includes a first tape, a second tape meshing with the first tape, and a slider slidably connected between the first tape and the second tape; the first adapter includes a first adapter part connected to the first tape and a first extension part connected to the first adapter part; a first card slot for clamping the luggage body is provided between the first adapter part and the first extension part; the first adapter part is provided with a first convex block protruding towards the first card slot. First, connect the first tape to the first adapter part, and then, snap-connect the first adapter to the luggage body, and the connection between the first tape and the luggage body can be completed, avoiding the problem of difficult sewing caused by directly sewing the zipper body to the luggage body, thereby improving production efficiency and product yield.
