Fastening for the inserted tooth, attached with a circular shape, of a circular saw

摘要

An inserted tooth (4) with a circular fastening surface is attached to a blade body (1) and in a recess with a round base, the opposite edges of which are parallel. The tooth (4) is locked in the recess by means of a rivet (6) which is arranged at a connecting point between the removable tooth and the blade body along a straight section of the edge of a recess. Such locking facilitates a robust construction of the tooth, and even a loose tooth can be re-fastened in its position by means of the flattening pressure of the rivet. <IMAGE>
