Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, a zipper in the prior art includes a first cloth tape 1 and a second cloth tape 2 distributed left and right, a first zipper tooth 3 is disposed on the inner side of the first cloth tape 1, a zipper head 4 is slidably disposed on the first zipper tooth 3, a socket 5 is fixedly disposed at the tail end of the first zipper tooth 3, a second zipper tooth 6 is disposed on the inner side of the second cloth tape 2, and the first zipper tooth 3 and the second zipper tooth 6 both include a row of single teeth 7 arranged in a vertical row. The tail end of the second zipper tooth 6 is fixedly provided with a bolt piece 8 which is in inserting fit with the socket 5, and a piece of cloth adhesive 9 is further adhered to the zipper, wherein the piece of cloth adhesive 9 is rectangular and is adhered to the position 1-2mm below the socket 5.
