For the securing of a tightening screw 6, a seesaw-shaped clamping piece 9 is arranged in a bearing bore 8, crossing the through bore 7 for the tightening screw. By means of an adjusting screw 12, the specially formed clamping piece 9 is rotated, one end of a planar portion of the clamping piece thereby pressing the tightening screw 6 against the wall of the through bore 7 for the screw, and thereby securing the screw against rotation. <IMAGE> |
