ABSTRACT:
A swivel adapter (26) has a base (60) with an outward facing first side (57) and a pivot surface (55) extending from the first side. A Center adapter (52) is mounted for pivoting motion on the pivot surface and has an outward facing first device connector (46). A clamp (78) has a clamp operator (80) operable to clamp the center adapter on the pivot surface at a desired orientation with respect to the base. A base unit handle (34) has a clamping mechanism (128, 138, 156, 164) connected to a body (120) having two split bores (36, 122), which is operable to clamp and unclamp the split bores on respective shafts. The clamping mechanism has linkage (138, 156) connected to a closing handle (164) to provide a mechanical advantage to the handle during the clamping action.
