Abstract
The utility model discloses a metal tooth comprising a fabric tape groove arranged at the rear end and a matching portion arranged at the front end. A first matching surface and a second matching surface are respectively arranged on an upper side and a lower side of the matching portion. A boss is arranged on the first matching surface and a groove matching with the boss in shape is arranged on the second matching surface. Left and right sides of the matching portion close with each other at an end portion far away from a connecting portion, and are connected with the first matching surface via an inclined surface. Since the left and right sides of the matching portion close with each other at the end portion far away from the connecting portion, and are connected with the first matching surface via the inclined surface, volume of the metal tooth is reduced, shock between a puller and the front end of the metal tooth is avoided, loss of the metal tooth is reduced, smoothness of a zipper with the metal teeth is increased and service life of the zipper is prolonged. The invention further discloses a metal zipper and a metal tooth mould.
