Problems solved by technology

However, common glue guns only have a fixed extrusion mechanism, and the glue output speed of the glue barrel can only be controlled by the user's hand pressing speed.
In fact, especially when the user's handle exerts a large force, it is extremely difficult to control the pressing speed of the hand while applying force.
In the process of starting to use the glue gun, usually due to problems such as long-term unused, partial colloid solidification, and static viscosity of the colloid, it usually requires a large force to drive the glue gun at the beginning of use, and after the glue is stabilized, The driving force required by the glue gun will be significantly reduced, and the fixed extrusion mechanism of common glue guns cannot solve these problems
And it often happens that when the glue gun is started to be used, it is hard to squeeze out the glue, and it is inconvenient to control the extrusion speed. After the glue is extruded, it is over-extruded, resulting in a waste of glue.

Abstract

The invention discloses a glue gun. The glue gun comprises a movable handle and a fixed handle, wherein the movable handle is connected with the fixed handle through a pivot pin shaft; an actuating part is further arranged on the movable handle; the actuating part is provided with an actuating part matched with a pushing part; and the distance between the pivot pin shaft and the actuating part isset to be switchable between two or more gears so as to change the magnitude of force exerted on the pushing part by the actuating part. According to the glue gun, the gears are adjustable so that switch between fast feeding and large-force feeding can be realized, and a user can adjust the glue gun according to actual needs.

Description

technical field [0001] The invention relates to the field of hardware equipment, in particular to a glue gun, which belongs to the technical field of production, processing, manufacturing and construction industry tools. Background technique [0002] In the process of using the glue gun, it is pushed by the lever of the gun handle to continuously squeeze the glue back and forth to make the glue come out. One end of the glue gun is provided with a trigger mechanism that is suitable for the user to hold and press. By pressing the trigger mechanism with the user's hand, the glue placed in the glue gun can be driven through the mechanical structure of the glue gun, so that the glue barrel can discharge glue at the glue outlet. A glue gun can be adapted to a variety of colloids with different characteristics, and the fluidity of different colloids is different. Common glue guns only have a fixed extrusion mechanism, so it is very difficult to achieve uniform glue output during t...
