Description

Technical Field

[0001] The utility model relates to the technical field of caulking guns, in particular to a caulking gun structure for building construction. Background Art

[0002] A caulking gun is a tool for sealing, filling and applying glue (usually glass glue), which is widely used in the field of construction. A caulking gun is usually used in conjunction with a glue cartridge (glass glue is filled in the cartridge). The pushing effect of the lever principle can be used to directly squeeze out the glue inside the glue barrel, and the sealing operation can be completed by aiming the pointed nozzle of the caulking gun at the construction gap of the house.

[0003] Since most caulking guns use manual squeezing to directly push out the gel inside the glue barrel, and the internal rebound component will be squeezed together during the manual force pushing process, the stacked resistance of the gel and the rebound component will increase the fatigue of the operator, thereby reducing work efficiency. In addition, due to the influence of the internal rebound component, if the operator's concentration is distracted, the handle is easily rebounded and hit, thereby reducing the operator's safety factor.
