A nozzle assembly for a nail gun includes three wing portions pivotally mounted on a nozzle holder to define a nozzle tapering towards a nozzle outlet. When the wing portions are in their inner closed position they can support an upholsterer's nail with the nail head resting on the inner walls of the nozzle, and the nail stem located in the nozzle outlet. When the nail is being driven into upholstery, the nail head forces apart the wing portions against the action of a resilient support ring. The wing portions may be surrounded by an outer casing which may be rotatable. This outer casing may have a cut-away portion or flat formed on it. |
