摘要

The plate (15) has a clamping device arranged at a casing surface of an end piece (24) of a stylus (11) or stylus combination or an adapter of the stylus, where clamping force of the clamping device acts perpendicular to a longitudinal axis (23) of the end piece of the stylus. The clamping device has a collet chuck (21), and a cone retainer (20) is fixed arranged at the plate. A nut (22) presses the clamping device into the cone retainer. The clamping device has a retainer that is adapted to the end piece. A holding device has a pin that is arranged in a casing (29).
