Motor driven saw with saw blade holder and an exchangeable saw blade, as well as the saw blade itself

摘要

The saw has a saw blade holder (1) for form-fit holding a saw blade (3) in a direction transverse to vibrating hub movement using a screw (5). The screw blocks the relative movement between the blade and holder in cooperation with edges (8', 8'') of the blade. The holder has a slot (2) that allows insertion of the blade transverse to the hub movement. The screw forms a rotatable joint in cooperation with a section in the blade running transverse to a saw edge of the blade by a diameter of the screw. The joint allows rotating of the blade around the screw.
