Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, and more particularly to an electric handheld glue gun. Background Art

[0002] A glue gun is a widely used tool for applying glue or other adhesives to specific locations for bonding or sealing. An electric glue gun is a tool that extrudes glue through an electric motor and is widely used in construction, decoration, manufacturing and other fields. Compared with manual glue guns, it has greater extrusion pressure and faster gluing speed, which improves work efficiency.

[0003] In the existing technology, handheld electric glue guns are prone to shaking during application, resulting in deviation in the application position, affecting the construction effect. At the same time, the nozzle of the glue gun is difficult to repair after being blocked, which affects the service life of the glue gun. The loading drive mechanism of the electric glue gun has a complex structure, which increases maintenance costs. Utility Model Content
