ABSTRACT:
The grip disclosed has a rotationally driven, threaded rod, with one part having a left-hand pitch while the other part has a right-hand pitch. The rod driving, by means of nuts and connection rods, has gripping arms that apply balanced forces to the object to be grasped. The arms and the threaded rod are floating with respect to the casing of the clamp, but can be locked as soon as the part is grasped.
