Abstract
The invention discloses a zipper which comprises a zipper belt with zipper teeth and a zipper head. The zipper head comprises an upper lock plate, a lower lock plate and a zipper division block, the zipper division block is provided with a first end and a second end, the first end is used for contacting with the zipper teeth, the second end corresponds to the first end, a containing groove and a threaded hole are formed in the zipper division block, the containing groove is provided with a first opening in the first end, the threaded hole is communicated with the bottom of the containing groove and provided with a second opening in the second end, a blade is telescopically arranged in the containing groove, the front cutting edge end of the blade is positioned in the first end, the threaded hole is connected with a screw in a threaded manner, the bottom end of the screw corresponds to the rear end opposite to a cutting edge on the blade, the top end opposite to the bottom end on the screw extends out from the second opening, and the screw is rotated, so that the bottom end of the screw is abutted to the rear end of the blade to push the front end of the blade to extend out from thefirst opening. The zipper can cut off a thread end when the thread end is clamped in the zipper head and / or the zipper teeth, so that locking of the zipper is avoided.
Description
technical field [0001] The invention relates to the technical field of zippers, in particular to an anti-jamming zipper. Background technique [0002] A zipper generally includes a zipper puller and two chain straps, each of which has a row of chain teeth, and the two rows of chain teeth on the two chain straps are arranged in a staggered manner. When people use the zipper, they often accidentally get the thread ends on the clothing stuck in the zipper head and / or the chain teeth so that the zipper is stuck. Because the zipper slider body is generally integrally formed, it is difficult for people to restore the zipper to normal with bare hands, and even the zipper will be damaged due to excessive force, which brings inconvenience to people's lives. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a slide fastener, which can cut off the thread end when the thread end is stuck in the slide fastener head and / or fast...
