Upper stopper structure of zipper

Abstract

An upper stopper structure of a zipper has two pull strips. Each pull strip has a respective teeth strip and each teeth strip is installed with a plurality of teeth. The right upper stopper includes an end stop and an inner stopper. A connecting plate is connected to the inner stopper, and an elastic fixing strip is extended from the end stop. The connecting plate is at an inner side; and the fixing strip is at an outer side of the teeth strip. The left upper stopper is a stop unit. An outer side of the top of the left upper stopper has a protruded stop block. The stop block is connected to one pull strip. The pull of the zipper is easily guided to pass through the teeth by using the stop structure, but the pull can not leave out of the upper stopper structure.
