Fixing device with wedge-shaped clamping parts for saw blades

摘要

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