• a cutter head having a main shaft hole in the middle thereof through which said cutter bead is coupled with a main shaft of the milling machine and having a plurality of semicircular engaging grooves at the rim thereof, a semicircular screw hole being formed in the middle of the top rim of said semicircular engaging grooves, a plurality of fixing screw holes being disposed under said semicircular screw hole of said semicircular engaging grooves;
• a plurality of hilts being semi-cylindrical and closely attached to said semicircular engaging grooves, a semicircular cavity with an annular flange being provided in the middle of the top rim of the hilt, a flat surface being formed opposite to said semicircular cavity of said hilt, two elongated holes in alignment with the fixing screw holes of said semicircular engaging groove being provided under the middle part of said flat surface, a blade for being received at the bottom of said hilt;
• and
• a plurality of trimming screws equipped with a threaded member around the shrank thereof and with an annular groove in the middle thereof,
• wherein said hilt is engaged into said semicircular engaging groove of said cutter head, and wherein said semicircular screw hole and said semicircular cavity just form a full circular hole for receiving said trimming screw, and wherein said annular flange of said semicircular cavity is engaged into said annular groove of said trimming screw, and wherein said threaded member of said trimming screw is screwed into said semicircular screw hole, and wherein the engaged position of said threaded member in said semicircular screw hole is changeable by tightening or loosening said trimming screw, thereby achieving the vertical adjustment of the position of said hilt, and wherein a plurality of fixing screws can be driven through said elongated holes on said flat surface of said hilt into said fixing screw holes of said semicircular engaging groove so that said hilt is stably fastened in said semicircular engaging groove.
