[0002] The manual glue gun is a tool for precisely controlling glue, sealant or other adhesive application, and is widely used in the fields of building, decoration, automobile maintenance, handcraft making and the like.

[0003] According to the search, the application number of the application is 201920519347.5, and a labor-saving structure device of a manual glue gun is disclosed. The labor-saving structure device of the manual glue gun includes a box body, a middle limiting plate and a lower limiting plate, which are fixedly connected in the box body, a double push rod which is slidingly connected to the box body, a front spring and a rear spring which are slidingly sleeved on the double push rod, a driving iron sheet and a resistance iron sheet which are slidingly arranged on the double push rod, wherein the two ends of the front spring are respectively abutted against the inner wall of the box body and the driving iron sheet, the two ends of the rear spring are respectively abutted against the middle limiting plate and the resistance iron sheet, and the driving iron sheet is located between the front spring and the middle limiting plate. The utility model only needs to push the rear resistance iron sheet to keep it vertical to realize pressure relief. The pressure relief part is arranged behind the resistance iron sheet. When the pressure relief button is pressed, the arched pressure relief block moves forward to push the resistance iron sheet to keep it vertical, thereby releasing the locking state of the push rod.
