ABSTRACT:
A caulking gun includes a gun body, a push rod, a push plate, an adjusting knob, and a piston lever. Thus, the adjusting knob is rotated to move away from the push plate to increase the incline angle of the push plate, so that the push plate is locked on the push rod in a tilt manner to lock and move the push rod without having to replace the push plate, thereby enhancing the lifetime of the caulking gun.
