Abstract:
A successive screw feeder driver comprising:a screw driving mechanism (3) having a grip handle (50);a drive unit (4) disposed within said screw driving by mechanism for driving a screw;a screw driving bit connected operatively and detachably to a clutch (21b) of said drive unit;a screw feed mechanism (6) connected for adjustment longitudinally and slidably to a front portion of said screw driving mechanism, said screw driving bit being slidably insertable into said screw feed mechanism and rotatable by said drive unit (4);a screw driving depth adjusting mechanism (23) in said screw driving mechanism for adjusting a depth a screw is to be driven by said bit;a screw feed means (24) constituted in said screw feed mechanism for feeding screws carried on a carrier strip member successively one by one to a screw driving position, means for driving said screw driving bit and said screws simultaneously with a longitudinal sliding motion of said screw feed mechanism, said longitudinal sliding motion being synchronized with a screw driving operation performed by said screw driving bit, a carrier strip member carrying thereon a large number of screws side-by-side;an adjustable screw guide passage for passage of said carrier strip member of said screws formed in said screw feed mechanism such that a position of said carrier strip member can be changed; anda front-end block having an abutment surface at a front end thereof, said front-end block being arranged adjustably in said screw feed mechanism and positioned at a desired longitudinal position with respect to the screw feed mechanism.
