ABSTRACT:
A caulking gun includes a gun body, a push rod, a push plate, an adjusting seat, a driving member, and an elastic member. Thus, the adjusting seat is movable in the gun body by rotation of the driving member to adjust the incline angle of the push plate by guidance of the tapered urging face of the adjusting seat so as to increase the incline angle of the locking hole of the push plate, so that the locking hole is locked on the push rod in a tilt manner so as to lock and move the push rod, without having to replace the push plate, thereby enhancing the lifetime of the caulking gun.
