US Patent 8646622 Adjustable tool support clamp

A clamp structure that provides versatility and structural adaptability to different clamping surfaces. A tension member can be coupled to the inside of a tubular body at one end and to a rod at the other end. Removable grips can be coupled to the ends of the body, but are not directly coupled to the tension member so that changing the grips can be done without removing the tension member from its anchored position. The grips can, in some embodiments, be pivotable so as to accommodate a variety of different gripping surfaces. Various holding members such as a tool holder, a utility hook and/or a claw grip can be movably provided on the body and can hold tools or light fixtures in a variety of configurations.
