FASTENER AND DOUBLE END ZIPPER WITH THE FASTENER

摘要

The present invention relates to a fastener, the convex member of the male fastener comprises a convex member body and a convex portion, and the convex member is adapted for contracting along the radial direction, as the convex portion is squeezed radially; the female fastener comprises a female fastener body and a receiving cavity formed on the female fastener body, the receiving cavity comprises a first slot and a second slot, a locking slot is formed on an inner wall of the first slot, for preventing the convex portion from separating from the female fastener axially, and a constraint guide slot is provided between the locking slot and the second slot, the convex portion is adapted for move along the constraint guide slot and between the second slot and the locking slot in a reciprocating manner, as the convex member rotates relative to the receiving cavity in a reciprocating manner, and the constraint guide slot has a shape that allows the convex member to be squeezed radially by the constraint guide slot, during the rotation process of the convex member from the second slot to the locking slot. The fastener in the present invention has a simple structure, it is reliable and easy to operate, when the fastener is used on the zipper on a luggage or a bag, it can prevent the luggage or the bag from being opened by a thief without drawing the attention of the carrier.
