Description

Technical Field

[0001] The utility model relates to the technical field of electric tools, in particular to an electric glue squeezing gun. Background Art

[0002] Glue is widely used in the manufacturing, construction and maintenance industries, especially in sealing and bonding processes. Although traditional manual glue guns can meet basic glue extrusion needs, they often have problems such as low efficiency and operator fatigue during large-scale production or long-term operations due to the need for continuous manual operation. In addition, manual glue guns also have certain difficulties in controlling the amount of glue extruded, which can easily cause glue waste or uneven extrusion.

[0003] In order to solve the above problems, electric glue guns came into being. Electric glue guns are driven by motors and can automatically complete the glue extrusion process, greatly improving work efficiency. However, electric glue guns on the market often lack precise control mechanisms during operation and do not have positioning structures. Users only know that the glue is exhausted when no glue is discharged. During this reaction process, the electric glue gun is still running, and the continuous squeezing of the push rod may cause damage to the equipment and reduce its lifespan. When the glue is exhausted, even if the electric glue gun is no longer driven, due to the continuous thrust of the push rod, a small amount of glue will still flow out of the glue outlet of the hose, which may drip onto the ground, causing trouble to the user.

[0004] Based on this, the applicant proposed an electric glue squeezing gun to solve the above technical problems. Utility Model Content
