Zipper

Abstract

A zipper, comprising two side zipper tapes (6), a slider (4), an insertion portion (1), a fixed pin (2) and a movable pin (3). Either side zipper tape (6) is provided with zipper teeth (5), and the slider (4) is used for operating the zipper teeth (5) on two sides to engage with or be separated from each other; the fixed pin (2) is arranged on the zipper tape (6) on a first side, and the insertion portion (1) is arranged on the zipper tape (6) on the first side and can fit with the fixed pin (2); and the movable pin (3) is arranged on the zipper tape (6) on a second side, and the movable pin (3) is configured to be inserted into the insertion portion (1) and cooperate with the fixed pin (2), such that the zipper teeth (5) on the two sides engage with each other after the slider (4) is pulled. The side of the movable pin (3) that faces the fixed pin (2) is provided with a tooth stop portion, which is provided with a tooth stop face (31), and the tooth stop face (31) is configured to abut against the zipper teeth (5) on the first side when the movable pin (3) is not inserted in place, so as to prevent the slider (4) from crossing the tooth stop portion; and the tooth stop face (31) is connected to the movable pin (3) by means of a transition face (32), so as to prevent the zipper teeth (5) on the first side from being stuck in the movable pin (3).
