[0002] Latex clothes are clothes that are worn close to the body, so a layer of fabric (hereinafter referred to as: chain cover) needs to be added at the position where the zipper is set to cover the zipper to prevent the zipper from directly contacting the body. However, during actual use of the zipper, the zipper head may pinch the chain cover, making it impossible to zip up or unzip, affecting wear, and in severe cases, the chain cover may be pinched and broken, causing damage to the clothes.

[0003] One existing technology is to divide the inner side and outer side of the zipper head and link them with screws, but this existing solution can only make it convenient to repair afterwards and cannot fundamentally prevent the problem from occurring during use.

[0004] Another existing technology is to design a split, which can ensure that the zipper head is disassembled after pinching the clothes to resolve the crisis and facilitate repair, but cannot prevent the clothes from being pinched.

[0005] Therefore, how to provide an anti-pinch zipper head expansion buckle that avoids pinching and is detachable is a problem that needs to be solved by those skilled in the art. SUMMARY

[0006] Therefore, the utility model provides an anti-pinch zipper head expansion buckle that avoids pinching and is detachable.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] An anti-pinch zipper head expansion buckle includes:

[0009] A support portion is provided with limiting protrusions on both sides, and the limiting protrusions are adapted to the two sides of the zipper head.

[0010] A limiting portion is provided at one end of the support portion, the top of the limiting portion is provided with a limiting plate, the limiting plate and the limiting protrusions form a limiting channel, and the zipper head is clamped in the limiting channel.

[0011] Further, the limiting protrusions are consistent in height with the locking portion at the lower end of the zipper head, and the two limiting protrusions cooperate to clamp the lower end of the locking portion of the zipper head.

[0012] Further, the limiting plate is provided with a limiting slot at one end close to the support portion.

[0013] Further, the support portion is provided with a clamping protrusion at one end away from the limiting portion. Further, the support portion is provided with a clamping protrusion at one end away from the limiting portion.

[0014] Compared with the prior art, the utility model discloses provide a kind of anti-pinch zipper head expansion buckle, the design is made without changing the original zipper any structure and function, utilize to give a layer of thickened shell to zipper head nesting, make zipper head and the chain cover piece of adjacent separation in running process, there is a gap between zipper head and the chain cover piece, and zipper head separates from the chain cover piece in the process of pulling together and opening, to avoid the condition of clamping material, without affecting the normal use of zipper head, easy to install and disassemble.
