摘要

The device (34) has a clamping screw shank (62) including a cylindrically-arranged shank portion (74) that extends through a bore portion (70) of a through-bores (52, 54). A conical-tapered shaft section (76) adjoins at the cylindrical shank portion of the clamping screw shank. The clamping screw shank is provided in the through-bores, and includes a minimum distance from a conical bore portion (72) of the through-bores. The minimum distance is equal to a predetermined spring travel of a plate spring packet (66) plus 0.3 times and 0.8 times the spring travel.
