Abstract

The drive for a screw, has a stationary housing (4) into which projects a central rod (3). This has an end (A) disposed pivotable chuck nozzle (8) sections for holding the screw. A control lever (11) permits or prevents engagement of tapered surfaces of a thrust sleeve (7) with outside ends of the nozzles to open or close the latter. By pushing on a hand grip (2) secured to one end of the rod, a cylinder (1) around the rod is rotated and the other end of the rod moves forward to the screw in order to rotate it. The forward movement of the rod entrains the thrust sleeve with it, disengaging the nozzles from the screw. The lever has a rear arm (15) to move the sleeve forwardly and a forward arm (16) to lock in a sleeve recess to hold the sections open.
