Abstract
A mechanism for quickly and precisely positioning one body relative to another body, which relies upon three support points between the two bodies. At a first point a hemispherical surface is received in an opening having the form of a trihedral pyramid. At a second support point a hemispherical surface is received in an opening having the form of a diahedral prism. At the third support point a rigid sphere held in loose confinement engages a flat surface.
