A clamping device (34) is provided between a screw base (32) and a lower side (30) of the blade base. The clamping device has a tension rod (36) that includes a thread, where the rod extends parallel to an extension of the screw. An anti-twist thrust bearing (38) is provided at an end (40) of the rod and screwed on the thread. Another inserted thrust bearing (44) is provided at another end (42) of the rod. A shaft-shaped dowel (46) is provided between the thrust bearings.
