Description

Technical Field

[0001] This utility model relates to an electric glue gun, and more particularly to a cordless electric glue gun. Background Technology

[0002] Electric caulking guns use a motor to generate power, which drives a connecting rod through a transmission device to squeeze the glue tube, allowing glue to flow from the nozzle. They are specifically designed for caulking. Compared to manual caulking guns, electric caulking guns are more efficient and dispense glue more evenly, thus finding widespread use in many fields. However, if the connecting rod continues to push forward after all the glue in the tube has been squeezed out, it will cause irreparable damage to the machine. Even under no-load conditions, if the connecting rod continues to move forward after reaching its final position, it will also damage the machine.

[0003] The utility model patent CN215390517U describes a stop switch at the rear end of the housing and a pressing part that cooperates with the stop switch on the push rod handle. However, this mechanical pressing type stop switch cannot guarantee that it will not fail after repeated use. Utility Model Content
