Measuring arm with multifunctional end

A measuring device, comprising:

• an arm made up of articulated elements including:
• a first fastener base;
• a first segment connected to the base by a first hinge;
• a second segment connected to the first segment by a second hinge;
• an interface body including a second fastener base and connected to the second segment by a third hinge;
• and
• position sensors associated with the hinges and electrically connected to an electronic acquisition unit for supplying the electronic acquisition unit with position measurement signals measuring the positions of the segments relative to one another, the interface body carrying a first measuring member and a handle enabling an operator to point the first measuring member at a zone of an object that is to be measured,
• wherein the handle is secured to the second fastener base, wherein the second fastener base has an end portion that includes a slideway that extends transversely relative to the longitudinal direction of the handle in order to co-operate with a slideway of the interface body, the interface body and the end portion of the second fastener base having both complementary abutment means so as to define a mutual engagement position of the slideways and also complementary locking means that oppose disengagement of the slideways, the complementary locking means including a control lever that is hinged to the end portion of the second fastener base between an activation position for activating the locking means and an inactivation position for inactivating the locking means.
