A combined screw strip and strip-advancing mechanism for a screw driving gun includes a sliding unit (5) connected telescopically to a barrel unit (4), and including two separated strip-positioning plates (53) each formed with an engaging groove (531) engaging movably a corresponding one of two engaging ribs (35) of a strip body (3) mounted with screws (30). A spring-biased positioning member (7) is mounted pivotally on the sliding unit (5) and abuts against the strip body (3) for maintaining engagement between the engaging ribs (35) and the engaging grooves (531). A lifting member (6) is connected pivotally to the sliding unit (5) by a pivot pin (43) movable along a guiding groove unit (411) in the barrel unit (4) such that the lifting member (6) pivots so as to lift upwardly the strip body (3) by a desired distance when the sliding unit (5) is moved from an extended position to a retracted position.
