An explosive actuated extendable driving tool has a housing with a barrel at its front end for receiving a fastening element that is to be secured in a ceiling, wall or the like. A manually actuated reciprocatable positioner shaft is slidably received in a retainer that is mounted to the back end of the housing, the positioner shaft being biased towards the back end of the housing. A load chamber formed which is in an inner end of the barrel is configured to receive an explosive charge. A muzzle with a self-aligning spall guard and splash guard are mounted to the barrel, the splash guard being disposed about the spall guard. A noise suppression element is contained in a chamber formed between the spall guard and the splash guard. Discharge ports formed in the barrel and spall guard define exits for the discharge of combustion gases and carbon into the noise suppression element. An extendable handle is connected to the back end of the positioner shaft, the handle operating as an actuator for firing the charge and driving the fastening element from the driving tool. |
