Anti-pinch zipper

An anti-pinch zipper, comprising two zipper tapes, and a zipper slider, wherein:

• said two zipper tapes each comprise a chain cloth and a row of teeth, each said chain cloth having an inner side thereof turned toward a front thereof and turned back to an outer side to form a chain belt portion so that a sliding space is formed between said chain belt portion and the associated chain cloth, said sliding space having an open side thereof facing the outer side of the associated chain cloth, said row of teeth being combined with said chain belt portion of the associated chain cloth, so that said row of teeth is located at the front of the associated chain cloth;
• said zipper slider comprises a top plate, a connecting device, a pull tab, a base core and two side plates;
• said connecting device being set outside said top plate, said pull tab having a front end thereof combined with said connecting device, the center of an inner surface of said top plate being convexly provided with said base core, said base core having a bottom end thereof provided with a first guide plate, the width of said first guide plate being greater than the width of said base core, a first chain tooth sliding groove between said first guide plate and said top plate being formed on two sides of said base core, said two side plates being vertically connected to two sides of the inner surface of said top plate, said two side plates each having a second guide plate at a bottom end thereof, an inner edge of each of said two second guide plates respectively having a convex plate protruding toward the center, a second chain tooth sliding groove being formed between said convex plates of said two second guide plates and said top plate, an inner edge of said convex plates of said second guide plates and two sides of said first guide plate being spaced to form a Y-shaped guide cloth seam;
• said zipper slider is combined between said two zipper tapes, said rows of teeth and said chain belt portions pass through said first chain tooth sliding groove and said second chain tooth sliding groove, and said two chain cloths extend out of said zipper slider through said Y-shaped guide cloth seam and expand to both sides of said zipper slider, so that the back of said two zipper tapes covers said zipper slider;
• said top plate, said connecting device and said pull tab are located at the front of the anti-pinch zipper, said top plate is leaning against said rows of teeth on the front of said chain cloths, and no parts of said zipper slider are present on the back of said two zipper tapes;
• and
• when said zipper slider moves, said first guide plate is between the inner sides of said chain belt portions of said two chain cloths, the inner edge of said convex plate guides said chain belt portions through said Y-shaped guide cloth seam, and said convex plate of each said second guide plate slides in said sliding space within said chain belt portions.
