Abstract
A chuck for a tubular body having a noncircular outer surface and an interior formed with a gripping formation has a spindle extending along an axis, axially displaceable claws in the spindle each having a pair of opposite ends, and a gripper head engageable with one of the ends of each of the claws in the spindle. This head is displaceable between a holding position in which the claws engage the gripping formation in the tubular-body interior and an open position disengaged from the gripping formation. The jaws move on displacement between the open position and the holding position by engagement of the gripper head with their one ends in a first pivotal movement and then at their other ends in a second pivotal movement to press their other ends against the working spindle.
