Abstract: Two pivotally secured jaws can be placed inside a bore in a mannequin head and pivoted away from each other by lock means to press tightly inside the bore, to detachably secure the head to the jaws. The jaws are supported by an upwardly extending rod, the lower end of the rod being attached to a sphere.The upward and sideways motions of the sphere are constrained by a hollow enclosure in which the sphere is disposed, and the downward motion of the sphere is constrained by a wedge that extends upwardly into the enclosure from the top surface of a table near the table's edge. An adjustable clamp presses the enclosure downwardly towards the top surface of the table. As the clamp is tightened, the wedge presses ever more tightly against the sphere, wedging it tightly against the enclosure and preventing the sphere from moving therewithin.
