• wherein the base body (13) has a rail (21) which extends in the direction of the longitudinal axis (L) and in which a guide section (23) of the sliding piece (15) is received and is displaceable in a guided manner;
• and
• wherein an axis of rotation (D) about which the screw element (17) is rotatably supported extends through the rail;
• wherein the rail (21) has a C-shaped section in cross-section and extends around the axis of rotation so that the axis of rotation extends within the C-shape;
• wherein the guide section of the sliding piece has protrusions that are received in recesses formed in the rail;
• wherein an outer facing surface of at least one of the protrusions is guided along and contacts an inner facing surface of the recess in which the respective protrusion is received, wherein the outer facing surface faces away from the axis of rotation;
• wherein the entire outer facing surface of the at least one protrusion is guided along and contacts the inner facing surface of the recess in which the respective protrusion is received.
