Abstract: The tool comprises, in a casing (2), electrically operated components and a housing (4) to accommodate a battery (3) that powers the said components, with detachable means (10, 24) of securing the battery in its housing in a position of mechanical locking and electrical connection to the said components and in a position in which it is mechanically retained in its housing but electrically disconnected.

Abstract: The apparatus comprises a removable magazine for the supply of fasteners, designed to contain a strip of fastener-holding rings, a fastener-guide (3) and a unit (4) for shearing the strip of fastener-holding rings, and which is functionally a single unit. The shearing unit (4) and the fastener supply magazine are adapted to work together to house a skirt (11), integral with the shearing unit (4), forming a passage (12) for fastener input, in a reception compartment of the skirt (11).

Abstract: The indirect-firing apparatus includes a combustion chamber for a cartridge (62), a trigger for igniting the cartridge, a barrel, an inertia block in the barrel, an anchor guide (7) designed to receive an anchor, a shuttle (34) in the anchor guide (7) mounted for movement from an anchor loading position to a position for firing and driving of the anchor, mechanisms (63, 11, 46) for displacement of the shuttle from one position to the other, and a barrel holder (61) for concomitantly controlling the closure of the combustion chamber (3) and means for displacement of the shuttle (34). The mechanisms (63, 11, 46) for displacement of the shuttle (34) are arranged so as to drive the shuttle (34) beyond the firing position (25). Damping components (33, 38), when the shuttle (34) has reached its firing position (25), absorb the action of the displacement mechanisms (63, 11, 46).
