Device for driving screws, rivets and the like
摘要:
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.
