<p>Saw blade clamping means (11) are formed by a pressing ball (12) arranged partially in a receiving space (5) for a saw blade (2), and an operating ring (13) arranged rotatably round rod-like part (4). The depth of the receiving space (5) in the clamping direction, is greater than the thickness of the saw blade (2), so that the blade can be pushed with its T-shaped outer end (3) along the lower blocking members (6). By means of a torsion spring (16) the operating ring (13) is biased relative to rod-like part (4) to a position in which recess (15) is removed as far as possible from receiving space (5) and ball (12) is pressed firmly into receiving space (5). In this position a saw blade (2) present in receiving space (5) is therefore pressed with force against rear wall (10) and thus fixed by blocking members (6,7). The rotation movement of operating ring (13) relative to rod-like part (4) is otherwise limited by co-acting stops (29,30). <IMAGE></p> |
