  • Magazine for a nail-driving powered tool
    Patent number: 7726534
    Abstract: A magazine includes a feeding tray having a nail path to allow passage of one nail strip and a loading space in spatial communication with the nail path and that is adapted for accommodating a plurality of stacked nail strips, a tray cover coupled to the feeding tray, and a first pusher unit connected detachably to the feeding tray and adapted to press against an uppermost one of the nail strips so as to push a lowermost one of the nail strips into the nail path, and a second pusher unit. When the lowermost one of the nail strips is moved into the nail path, it is pushed toward the nail outlet by the second pusher unit. The tray cover is slidable to uncover at least one of the nail path, thereby permitting an additional nail strip to be placed into the nail path.
