ABSTRACT:
A screw driving gun includes a tubular barrel extending frontwardly from a gun housing to define a chamber in a longitudinal direction, and a tubular slider coupled slidably to a front end of the barrel. A front portion of the tubular slider has two opposing slots in the longitudinal direction for passage of a screw feed belt therethrough in order to register a screw on the feed belt with the chamber of the barrel. A screw orientation guide member is connected to the slider, and has a front section formed with an abutting end for abutting against a work piece surface, and a plurality of holding units cooperatively confining a guide passage in the longitudinal direction between the slider and the abutting end. The guide passage tapers to form a constricted front end proximate to the abutting end. The holding units cooperatively provide radial inward holding forces on the screw to prevent the latter from deviating from the longitudinal direction. A screw driving shaft is disposed in the chamber, and has a turning bit extendible into the slider for rotating the screw.
