A coordinate measurement machine 10 has a movable head 20. A probe 12 and arm 14 are attached via a disconnectable joint to the head. An exchange rack 30 is provided for exchanging one probe/arm, for another. A plate 50 acts to disconnect and reconnect the joint and also to support the probe/arm whilst disconnected. Plate 50 actuates a toggle mechanism 42 when the head is moved relative to the plate and causes a plunger 26 to engage/disengage with a peg 24 thereby securing or releasing the joint during the said movement. |
