ABSTRACT:
A retracting power clamp includes a body having a generally cylindrical external surface. A clamping arm is movable from a retracted position to a clamping position with the arm being linearly extendable and pivotable relative to the body when moved between the retracted and clamping positions. Another aspect of the present invention utilizes a spring biased plunger for selectively engaging a detent in the sleeve to encourage the sleeve and arm to remain in a fully retracted position if fluid pressure is lost. A further aspect of the present invention provides various mount configurations.
