Abstract:
A screw driving tool for screwing a screw into a constructional component, comprising a housing (1); a hollow spindle (3) rotatably supported in the housing (1) having limited axial displacement relative thereto; a screw-in spindle (5) at least partially extending in the hollow spindle (3), connected thereto for joint rotation therewith and supported for a limited axial displacement relative thereto; an impact mass (15) cooperating with a surface of the screw-in spindle (5) for displacing the screw-in spindle (5) in a direction in which the screw is screwed into the constructional component; a drive motor (2) for rotating the screw-in spindle (5) and having an output shaft (19); and a clutch (6) located between the hollow spindle (3) and the drive motor output shaft (19) for transmitting rotational movement to the hollow spindle (3) and thereby to the screw-in spindle (5).
