Abstract:
A clamping device for motor-drive straight-back and saber saws fixable to a lifting rod, the clamping device comprising a clamp holder; a movable clamping piece arranged relative to said clamp holder so that a saw blade can rest between said clamp holder and said movable clamping piece, said clamping piece having a first side which faces toward said clamp holder and has a surface adapted to abut against the saw blade, and also a second side which is remote from said clamp holder and has a wedge-shaped surface; a wedge piece having a wedge-shaped surface abutting against said wedge-shaped surface of said clamping piece and also having an opposite surface; a first spring acting on said wedge piece in a direction essentially perpendicular to a displacement direction of said clamping piece so as to move said clamping piece into a position of repose so that said first surface of said clamping piece presses against the saw blade; and a second spring acting on said clamping piece so as to press said clamping piece against said wedge piece.
