Claims

[Claims for Utility Model Registration] 1. A cutter structure consisting of a plurality of divisible blades assembled, each of which has an opening for attachment to the rotating spindle in its center and a cutting edge provided at its tip. holes that extend generally parallel to the mounting opening and communicate with at least an adjacent blade to regulate the mounting angle in the rotational direction between the blades, and members fitted into these holes; A cutter structure comprising: a cutter structure in which at least a portion of the member is enlarged in diameter, thereby making it possible to accurately determine the mounting angle in the rotational direction between the cutters. 2. The member fitted into the hole is a positioning pin having an internal thread and a split groove on at least one end, the other end of the pin is fixed in the hole of one of the adjacent blades, and one end of the pin A tapered screw member is screwed into the internal thread of the blade, and by screwing the screw member, one end expands in diameter within the hole of the other blade, allowing accurate indexing of the mounting angle in the rotational direction of the double-edged blade. The cutter structure according to claim 1, wherein the cutter structure is made possible.
