Description

glue gun

The present invention relates to a glue gun.

Generally, a glue gun is used to fill the gap between the walls or the gap between the two objects. and a pressing handle which can push against the driving element. When in use, press the handle to drive the push rod to push the rubber cylinder forward to control the glue discharge. When the push rod pushes the rubber cylinder forward, the pressure will accumulate inside, causing the glue to continuously leak from the glue outlet of the rubber cylinder. .

The existing non-dispensing glue guns on the market improve the problem of continuous leakage of colloid. The conventional non-dispensing glue gun can only solve a certain amount of accumulated pressure to prevent glue leakage. However, the pressure accumulated when the push rod pushes against the rubber barrel will vary due to the size of the glue outlet, the consistency of the glue, the distance the push rod moves, etc., and the conventional non-dispensing glue gun cannot Effectively respond to various pressures generated in the cartridge.
