Convenient puller

Abstract

The invention relates to a convenient puller which can be zippered accurately and conveniently without zipper pulls. The convenient puller comprises an upper fin, a lower fin, a guide pillar, a nut cap, a stop sheet, a restoring spring and a fastening cap, wherein the upper fin and the lower fin are connected into a whole by the guide pillar; the stop sheet passes through a stop hole formed on the upper fin movably, extends towards the lower fin and is clamped between two adjacent chain teeth to prevent the puller from sliding on the chain teeth; the stop sheet and the nut cap are formed integrally; a convex pillar is arranged on the upper fin, and passes through a through hole formed on the nut cap; the restoring spring passes through the outer side of the convex pillar; the bottom end of the restoring spring is clamped in a first positioning step arranged in the through hole, and the top end of the restoring spring is clamped to the lower end of the fastening cap; and the fastening cap is riveted with the top end of the convex pillar exposed out of an upper end opening of the through hole.

Description

technical field [0001] The invention relates to a zipper, in particular to a convenient slider that can be pulled and closed without a pull piece. Background technique [0002] On modern clothing or various bags, the setting of the zipper structure is very common. A good zipper can bring more convenience to users, but if there is a problem with the zipper, it will often cause great inconvenience in the use of clothing or bags. Existing slide fasteners generally include fastener elements, sliders, pull tabs, and upper and lower fins, and the sliders walk on the fastener elements to realize the engagement and separation of the fastener elements. Such as figure 1 The slider includes an upper wing 1', a lower wing 2', a guide post 3', a cap 4', and a stop spring 5', wherein the upper wing 1' and the lower wing 2' are integrally connected by guide posts 3'; two fixed blocks 6' protrude upward from the upper surface of the upper wing 1'; Fixed connection; the stop spring 5' is...

Problems solved by technology

For the slider set in this way, since the pull piece is used to pull the stop reed 5' to overcome the elastic force of the return spring 7', if the pull piece is too hard, it is easy to cause the return spring 7' to fail to reset, thereby making the entire slider useless; at the same time Because it uses the stop reed 5' to be inserted between two adjacent chain elements to prevent the slider from sliding on the chain elements, so when the stop reed 5' needs to be inserted between the chain elements again, it will be blocked by the stop spring. The position reed 5' cannot accurately locate the gap between the chain elements, resulting in the zipper not working properly
