Abstract: A device for adjusting an elevation of a piece comprises a body and a pin. The body is intended to be secured to a support, and has an internal surface defining a central cylinder provided with an internal thread and having a first opening. The pin has an external thread, a first end for carrying the piece, and a second end. The pin and the body are connected to one another through their respective threads. The pin can, when rotated, move in a longitudinal direction to adjust the elevation of its first end. The pin has at least two longitudinal slots on its second end to define at least two flexible legs. The body has at least one boss on its internal surface configured to bend the flexible legs and to fit into one of the slots during the rotational movement of the pin so as to index an elevational position of the piece.
