Saw-blade fixation device

Abstract

The invention relates to a device for mounting a saw-blade provided with an opening to a carrier which is connected to a drive device to make a reciprocating movement, wherein the device comprises: a wall extending in the direction of movement which is suitable for contact with a side of the saw-blade; a mounting body which is rotatable opposite the wall around a shaft extending perpendicularly of the direction of movement and parallel to the wall and which is provided with a protrusion which is movable into the opening arranged in the saw-blade; and urging means for urging the mounting body to a mounting position wherein the protrusion extends into the opening arranged in the saw-blade. Mounting takes place because via the sphere the saw-blade generates a moment in clockwise direction relative to the shaft. This moment is counteracted by a moment that is generated by the friction between the actuating rod and the contact surface.
