ABSTRACT:
The device (12) comprises a laser (14) which is attached to the tool (2). During operation a laser beam (16) is emitted onto an optical lens (20) which is of cylindrical shape. The lens (20) is suspended to swivel freely, e. g. by means of a swivel arm (24) which is operatively connected to the tool (2). Thus, the main axis (28) of the lens (20) is kept vertically by the gravity force when the tool (2) is moved or tilted. The shape of the laser marker (I1II, III) generated on a workpiece (8) is an indication for the user of the tool (2) concerning an inclination (x, y) of the tool (2).
