Insertion pin and insertion pin assembly for zipper

Abstract

An insertion pin for a zipper, in which the insertion pin has an insertion pin body with a first side and a second side that are opposite to each other and lengthwise along the insertion pin body is provided. A first receiving slot is formed on an interior of the insertion pin body. The first side has a slant surface close to a head of the insertion pin body. Via the aforementioned design, interference can be prevented when the insertion pin inserts a slider tab, and thus making the insertion action smooth. An insertion pin assembly is further provided.

1 . An insertion pin for a zipper, in which the insertion pin has an insertion pin body with a first side and a second side opposite to each other and lengthwise along the insertion pin body, wherein a first receiving slot is formed on an interior of the insertion pin body and the first side has a slant surface close to a head of the insertion pin body. 
     
     
         2 . The insertion pin of  claim 1 , wherein the insertion pin is made of metal. 
     
     
         3 . The insertion pin of  claim 1 , wherein the first receiving slot extends along the second side to one rear of the insertion pin body.
