One embodiment of the present invention is directed to a clamping device with
an attached arm in which the act of opening the clamp makes the arm flexible and
the act of closing the clamp makes the arm rigid. By operating in this manner,
the present invention may allow a worker to position the arm (while flexible) in
any number of different and easily attainable positions while also allowing the
worker to secure a workpiece and immobilize the arm in a single step. In another
embodiment of the present invention the arm can be made flexible independently
of opening the clamp.
