Ring (8) is drawn back, compressing spring (11). Holes in the cutter are placed over the heads (14) of fingers (7). The cutter is rotated slightly, in the opposite direction to holder rotation, to engage slots (15). The ring is released and the attached pins (10), which have conical heads (10) and are offset slightly from the corresponding holes in the cutter, hold the cutter in the slots. |
