Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a soft glue gun. Background Art

[0002] Glue is used to bond two objects together. There are many kinds of glue on the market. When glue is used between joints, glue guns are used because the width of the joints is generally small. From the packaging of glue, it can be divided into hard packaging glue and soft packaging glue. Among them, hard packaging glue is tube-packed glue, which means that the packaging of glue is a hard plastic tube or a cartridge-like shape; and soft packaging glue is commonly known as sausage-packed glue, which means that the packaging of glue is a soft plastic bag or a sausage-like shape. In order to cooperate with the use of soft packaging glue, a soft glue gun is designed. However, the existing soft glue gun has the same amount of glue output each time because the stroke of the push rod is the same each time, and the amount of glue output each time cannot be adjusted according to actual needs, which has poor practicality.
