[0002] At present, there are various styles of sports tops on the market. One style is that the front placket of the sports top is designed with a zipper. The conventional sewing method is to first place the front piece, then align the zipper strip with the front piece, and then manually sew them with a flat sewing machine. Since the sewing needs to be done while aligning, the seam line between the front door and the zipper is not straight after sewing, and the positions of the chest pockets and large bags on both sides of the front door are prone to deviation after the zipper is closed.

[0003] Based on this, the Chinese patent with the announcement number CN 204467038 U discloses a mold for sewing zippers on the front doors of clothing tops, which includes an upper template, a middle splint, and one side of a lower template, which are fixedly connected to each other; corresponding positions on the upper template, the middle splint, and the lower template are provided with sewing grooves that are consistent with the shape of the sewing zipper; the middle splint is provided with a zipper groove to fix the zipper, the middle splint and the lower template clamp the lining, and the upper template and the middle splint clamp the zipper. When processing in this way, the lining is laid on the lower template, and then the middle splint and the lower template are put together, and then half of the zipper is fixed in the zipper groove, and finally the upper template, the lower template and the middle splint are put together, and the sewing machine is used to sew along the sewing groove to complete the sewing of half of the zipper.

[0004] The above structure solves the problems existing in manual sewing, but the template can only sew half of the zipper, and the sewing of the other half of the zipper requires the above steps to be repeated, which is relatively inefficient. The structures of the two half zippers are different. The half zipper without a zipper head does not need a groove to place the zipper head. Therefore, using the same template for sewing cannot match well. Utility Model Content
