Abstract: A stapler for driving metal staples which are fed through a guide channel to an ejecting channel under the action of a pusher member moved by resilient means on a pair of walls located inside the stapler frame, on said walls there being positioned a strip of metal staples. The inner walls and one side wall of the stapler are shorter than bottom wall of guide channel, so that it is possible to make pusher member to back up until it disengages from inner walls and may be rotated substantially 90.degree. allowing the insertion of a new staples strip once the previous one has been used up.

Abstract: An improved tool for driving metal fasteners, such as nails, brads, tacks, staples and the like in a frame and setting its rear closing panel. The tool comprises a driving lever suitable to urge, against a loading spring, a driving hammer which slides in the hollow bed of the tool. When the driving lever and the driving hammer disengage each other, the compression spring urges the driving hammer towards the outlet opening of the metal fastener, the latter being fed from a feeding magazine essentially perpendicular to the direction towards which the hammer is moved said magazine being provided with a pusher member for the metal fasteners.
