Caulking gun and cartridge

摘要

A caulking gun with the open supporting framework that has a forwardly disposed ring member and a rearwardly disposed trigger actuating mechanism that is cooperative with a rod member with teeth thereon to advance the piston on the one end of the rod member which in turn operates on a moveable member in a disposable cartridge that is received by the supporting framework. A nozzle is removably connectable with the cartridge and is also removably connectable with the ring member of the gun to provide selective detachment.
