发明名称 SCHRAUBENZIEHER MIT EINRICHTUNG FÜR AUSTAUSCHBARE EINSÄTZE
摘要 An improved screwdriver in which a replaceable bit is removably secured in an axial socket in the end of the mandrel with a slot extending radially inwardly into the socket rearward of the bit. A separate bit removing lever tool is provided having a hook-shaped portion which curves back on itself to a distal end. The hook-shaped is insertable via the slot into the socket to assume a position with the distal end extending forwardly into the socket to engage the rear end of the bit with surfaces of the hook-shaped portion to engage both a forwardly directed engagement surface of the rear of the slot and the side walls of the socket such that pivotal movement of the tool guides and cams the distal end into the socket and into engagement with the bit to urge the bit forwardly out of the socket.
