ABSTRACT:
A support elevated over a substrate base and carried by a joint head whereupon it is angularly adjustable and fixable in a plurality of desired positions. The support is a bulky parallelopipedic body combined from a pair of mirror-like configured halves hinged one upon the other by means of at least one screw bolt located proximate to one end thereof. In their interior from their lower side, these halves are provided each with one hollow recess which together complementarily form a regular spherical cavity. The joint head is a pheric corpus mating by its configuration with the spherical cavity in the bulky body, and is provided on top of, and unitary with, a leg-like rod projecting upwardly from the substrate base. At the side of the bulky body distal from the hinging screw bolt, a tightening bolt is provided projecting to, and operable from, outside by means of which the interengagement of the pair of halves and between the cavity and the joint head may be either loosened or toughened for permitting, respectively, angular motion and fixation in a selected position of the bulky body. On top of the bulky body, a vise may be affixed operable for distancing or approaching its jaws by means of a screw bolt extending along the longitudinal axis of the bulky body.
