The head (1) has an universal joint (5) arranged between connection points at ends of an inclination device (2), and a holding device (100) secured on the universal joint to hold an optical instrument e.g. camera, telescope and spotting scope. A clamp ring (9) with an inclined surface (12), which is narrowed to a central longitudinal plane along a direction to the universal joint, is arranged in a bearing housing (3), where the clamp ring is expandable at an opening. The inclined surface works together with a complementary formed counter-slope (13) at an axially movable slide bearing (7). |
