The measurement point defining component (5) is fitted on and translatable across the arm (4) at a distance from the second rotary axis. The component is angularly adjustable in relation to the plane set up by the arm and the first rotary axis. Its distance to the second rotary axis is adjustable. The arm is rotatable around a longitudinal axis (21) in the arm for producing the angle adjustability in the measurement point-defining component. The arm is translatable along a longitudinal axis (21) in it for producing the ability to regulate of the distance to the second rotary axis. The arm, at least on a part of it, is fitted on the holder (2) and has an essentially circular cross-section. It is fitted in a longitudinal channel (13) with a diameter corresponding to the cross-section for producing the translatability and rotability. |
