Abstract: A device for driving a screw, pin, rivet or the like into a threaded or drilled hole is disclosed which is adapted to operate a nozzle comprising a pair of nozzle halves to pinch it. When driving a screw by means of the device as a screw driver, a thrust sleeve is displaced forwards by operating an E-shaped control lever on a stationary cylinder and thereby the nozzle halves are depressed at their rear parts so that they are opened. Then the screw to be driven is located in position midst the nozzle halves kept open and thereafter the control lever is restored to the original position. A press block is displaced forwards by means of a spring in the thrust sleeve and expands the nozzle halves, causing the nozzle to be opened to firmly hold the screw.

Abstract: A device for driving screws, rivets and the like is disclosed which has a nozzle consisting of an upper half part and an under half part, which are movable relative to each other. By pressing a lever with a finger of the operator and then releasing it, the nozzle is opened and closed in order to grasp screws, rivets and the like. Between the two halves of the nozzle a center rod extends coaxially with the nozzle; and, by pressing a grip end cylinder of the device, the nozzle is opened and simultaneously the center rod is thrusted towards the tip of the nozzle so that the rivet or the like may be pushed out. Alternatively, by rotating a rotary cylinder of the device while pressing the grip end cylinder, the center rod is thrusted towards the tip of the nozzle and rotated so that the screw may be driven in a work piece.
