Abstract:
A grip extension linkage to provide a gripping tool having radial gripping elements with an improved operational range. The grip extension linkage includes at least one annular body having a central internal bore and an peripheral external surface. There is provided rigid elongated spokes. Spoke guides are provided on the annular body. The spoke guides are in close fitting relation with the spokes to constrain the spokes while allowing them to move radially from a retracted position to an engaged position.
