ABSTRACT:
A tool for rotating a rod is provided which is formed of three members. A first member is formed as a sleeve and has an internal opening size to receive the rod. This sleeve has a tapered, portion which is placed over the rod. A second member, which may also be in the form of a sleeve slips onto the first sleeve and engages against the tapered portion. A third member sleeve is axially fixed to one of the first and second members and engages against the other of the members. A mechanical arrangement is provided to selectively urge the third sleeve apart from the other members against which it engages in order to move the second member and the first member relative to one another along the tapered surfaces to collapse the end of the first member engaging the rod to increase the gripping force of the first member with the rod. The first member has a shaped contour for receiving a torque applying device, such as a wrench, so that the first member can be rotated, thus rotating the rod.
