[0002] Zipper is a connecting piece that makes articles together or separates, which is widely used in clothing, bags, tents and other applications. The zipper includes a zipper head and a chain. The traditional zipper head is mostly integrally cast in production, which is simple in structure.

[0003] At present, there are various types of pullers, such as nylon, metal, plastic steel and other pullers. For example, the Chinese patent document with the publication number CN106560108B discloses a module combined zipper head, which includes a puller body and a puller. The puller body includes an upper wing piece, a lower wing piece and a support core. The support core connects the upper wing piece and the lower wing piece into one body. The top surface of the upper wing piece is provided with a mounting groove penetrating through the front or rear side of the puller body. The mounting groove is provided with a pull nose mounting part. The pull nose mounting part includes a mounting plate, a self-locking part and a cap. The mounting plate is clamped in the mounting groove. The self-locking part is fixed on the top surface of the mounting plate. The groove opening of the mounting groove is provided with a limiting block. The limiting block extends into the mounting groove to hold the top surface of the mounting plate. The puller body can be easily assembled for different designs of pull nose mounting parts, making the zipper head more personalized.

[0004] Although the pull nose mounting part is personalized, the upper wing piece and the lower wing piece are connected into one body by the support core. Some parts are damaged and cannot be replaced with individual parts. The entire puller must be replaced, and even the entire zipper must be replaced. The Chinese patent document with the publication number CN104287323A discloses a puller structure for zipper with nano-pores on the surface, which is easy to disassemble. The puller structure includes a puller lower wing plate and a puller upper wing plate corresponding to the puller lower wing plate combined as a zipper head. At least one hollow part is provided on the front side of the puller lower wing plate. The lower segment of the hollow part is arranged with an inclined and outwardly expanding wall surface. At least one clamping piece is protrudingly formed on the front side of the lower side wall surface of the puller upper wing plate, which corresponds to the hollow part. A clamping groove is provided on the clamping piece. At least one clamping pin is inserted into the clamping groove. The clamping pin is inserted into the lower segment of the wall surface of the hollow part and passes through the clamping groove to fix the puller upper wing plate and the puller lower wing plate. The zipper head can be quickly disassembled, greatly facilitating the solution to the problem of the zipper head and the cloth belt being stuck during pulling. Although the prior art solves the problem of disassembly, the clamping piece and the clamping pin are scattered, which is not convenient for disassembly.

[0005] For example, the Chinese patent document with publication number CN219719941U discloses a detachable zipper head, belonging to the technical field of zipper heads, relates to a quick-release zipper head, comprising an upper wing plate and a lower wing plate, the upper wing plate is hinged with the lower wing plate, a connecting cavity is formed on the lower wing plate, the upper wing plate is slidably connected with a rod body, the rod body is rotatably connected with a connecting assembly after penetrating through the upper wing plate, the connecting assembly can be hingedly connected with the lower wing plate, the rod body is connected with the connecting assembly after penetrating through the upper wing plate, the connecting assembly is hingedly connected with the lower wing plate, the rod body is moved downward to separate the connecting assembly from the lower wing plate during disassembly, the product has the advantages of quick disassembly, compact structure, resistance to damage caused by external factors, and multiple reuse. The prior art hingedly connects the upper and lower wing plates through the connecting assembly, which makes the structure more complex, and even ordinary consumers cannot disassemble and assemble it, which also leads to the loss of parts and the scrap of the entire zipper head.

[0006] The Chinese patent document with publication number CN211021251U discloses a detachable puller, comprising an upper wing plate and a lower wing plate detachably fixedly connected with the upper wing plate through a fastener, a cap is detachably connected with the upper surface of the upper wing plate, and a puller is rotatably connected in the middle of the cap. The utility model discloses a zipper. The detachable puller is detachably connected between the upper wing plate and the lower wing plate, the puller is detachably connected between the cap and the upper wing plate, when the puller is damaged, only the damaged part needs to be replaced, and the disassembly process is convenient and fast. The detachable structure of the puller structure is simplified, but the upper and lower wing plates still need to be connected through an additional fastener (screw), which needs to be accurately positioned and screwed in the manufacturing process, and the manufacturing cost is high. For consumers, tools are also needed to unscrew the screws for disassembly, which is not convenient. Moreover, the screws are exposed outside the zipper head, affecting the appearance of the zipper head. SUMMARY
