A cylindrical blade holding element (7, 9) wider at the rear and with a groove (12) positioned alongside can be axially moved inside the bore (5) when the blade (17) accommodated inside the groove (12) and swivel mounted to the holding element (7, 9) has to be exchanged. Before the blade (17) is pulled to the front a radial positioned screw with a sunken head (4) has to be loosened.</p> |
