The clamping head (10) has a clamping element (12) to clamp the rod element (5) radially to rod axle (6). A lifting unit (30) produces an axial lifting movement and a wedge-shape sliding mechanism (50) is formed by actuating rod (52). The actuating rod is supported movable diagonally to rod axis that id equipped with a guide bore (54). The actuating rod is connected at an end with the lifting unit and the other end has a clamping unit. An independent claim is also included for a drilling device with drilling drive.
