A blade mounting device is operable for mounting a blade (B) on a movable member (21) of a cutting member which is moved in a predetermined motion for a cutting operation. The blade mounting device (11) includes a pair of claws (41b) mounted on the movable member and operable by an operator between a closed position for clamping the blade (B) and an open position for releasing the blade (B). A first and a second thread mechanism (31a/21c;31b/41c) are provided for converting the rotation of the actuation member (31) into an axial movement of the actuation member (31) relative to the movable member (21) and for converting the rotation of the actuation member (31) into an axial movement of the claws (41b) relative to the actuation member (31).
