Slide fastener

The utility model relates to a zipper, in particular to a zipper comprising a puller and twisting teeth. The technical proposal is adopted as follows, the twisting teeth with same structure are positioned in two rows and matched with the groove of the puller (9), and a single twisting tooth (12) comprises a transverse baffle, an intermediate baffle, a bottom plate and an upright post. The transverse baffle, the intermediate baffle and the bottom plate are positioned mutually in parallel. The upright post is positioned perpendicular to the plates and is simultaneously arranged in the middle part as well as connected the transverse baffle, the intermediate baffle and the bottom plate, and the whole is shaped like a Chinese character ''wang''. After the common zipper is changed to be opened and closed along the vertical direction of stress plane, and the zipper is only opened and closed at the direction vertical to the stress plane, therefore larger twisting teeth are allowed to be applied, consequently the zipp
