A cartridge powered fixing tool having a housing (10), a guide tube (20), a nail driving piston (40) with a push flange (43), and a reset lever (50) pivoted about an axis (61). After firing, a spring (28) co-acts with the housing to urge the guide tube forward to its rest position causing a profiled cam (52) to be rotated via a control ratchet (23) and thereby moving the reset lever to allow the driving piston to reset to the starting position for next use.
