The arm has a joint part (12) with a bearing sleeve (13) slid on a cylindrical pin (6) of another joint part (5). A friction surface (15) is aligned perpendicular to a center axis, and is placed on a contact surface (11) of the pin. Another friction surface (16) is loaded over pressure disks, where a surface presses over a clamping force of one of the pressure disks in an area of one of the friction surfaces. The pressure disk is rotated-securely and connected with one of the joint parts, and the other pressure disk is connected with the pin. |
