An improved support for pivotally mounting an instrument housing formed of a bracket having spaced apart parallel planar portions which are normally of spacing less than the width of the housing and deflectable outward relative to each other, each of the bracket planar portions having an opening therein, the openings being in a common axis and each having a slot extending from a surface of the bracket and communicating with the opening, the width of the slot being less than the diameter of the opening, the housing having internally threaded tubular trunnions on opposite sides thereof in alignment, the diameter of the trunnions being less than the diameter of the opening in the bracket planar portions and greater than the width of the slots, and a pair of knobs, each having a threaded portion extending therefrom that are threadably received in the trunnion threaded openings, the diameter of the threaded portions being less than that of the slots so that when the knobs are loosened the bracket planar portions may be spread apart and the instrument removed from the bracket by the threaded portion of the knobs passing through the slots without removing the knobs.
