ABSTRACT:
A powder-actuated fastener-driving device includes a hollow body including a tubular portion and a handle, and an inner tube movable forwardly and rearwardly within the tubular portion and having a front end disposed outwardly of the tubular portion, and a slot. The front end of the inner tube has an outer surface formed with a position-limiting groove. A stop member is disposed within the tubular portion, and extends into the slot. A sound-absorbing sleeve is sleeved movably on a portion of the tubular portion disposed outwardly of the handle, and has an inner surface formed with a position-limiting block, which is movable forwardly and rearwardly within the position-limiting groove. When the front end of the inner tube is pressed forwardly against an object, the sound-absorbing sleeve comes into contact with the handle.
