A driving mechanism for use in a fastener driving tool, said driving mechanism comprising: (a) a guide body that receives a fastener that is to be driven from an exit end of said driving mechanism; (b) a movable driver actuation device; (c) an elongated driver member that is in mechanical communication with said movable driver actuation device at a first end of said driver member, said driver member having a second, opposite end that is sized and shaped to push a fastener from said exit end of the driving mechanism, said driver member ' having a direction of movement between a first end travel location and a second end travel location, said driver member having a first contacting surface between said first end and said second end, said driver member having a ready position proximal to one of said first end travel location and said second end travel location; and (d) a lift mechanism which includes a movable arm that exhibits a proximal end and a distal end, said proximal end being in communication with said guide body and said distal end having a lifter subassembly mounted thereto, said lifter subassembly including a second contacting surface (262, 268), said movable arm being movable between a first position and a second position, said movable arm being biased toward said first position, said movable arm having a mechanical freedom of movement toward said second position, and if said movable arm is in said first position, said second contacting surface (262, 268) of the lifter subassembly is in an engagement position with respect to said first contacting surface of the driver member; (e) wherein: (i) during a lifting stroke, said second contacting surface (262, 268) of the lifter subassembly attempts to contact said first contacting surface of the driver member and thus cause said driver member to move toward said ready position; (ii) however, during said lifting stroke, if said driver member and said lifter subassembly are misaligned, such that said first contacting surface cannot engage with said second contacting surface (262, 268) to move said driver member toward said ready position, then said movable arm automatically releases from said first position and allows said lifter subassembly to displace toward said second position, which allows said second contacting surface (262, 268) to move past the misaligned first contacting surface without jamming.
