Document Type and Number:
WIPO Patent Application WO2000071299
Kind Code:
A3
Abstract:
The invention concerns a motorised screwdriver with an automatic system for loading screws or bolts, enabling to save time when working with screws or bolts. It consists of a barrel/guide with a magazine (20). The barrel/guide is automatically loaded by the mechanical system (9), (10), (11a), (11b), (16) and (16a) with a screw or a bolt (7) held by a magnet (8), coming from its magazine (20). The screw or bolt is driven in by means of a thread bar with a bit (6) which penetrates a socket/nut (5). Said thread bar is rotated by an adjustable engagement of the torque (2) which is adjusted by a ring (3). The adjustable engagement of the torque is rotated by a variable speed electric motor. A locking system (via the socket/nut (5)), enables to convert the motorised screwdriver with automatic system for screws or bolts into a standard actuated screwdriver.
