Abstract

A blade holding device comprising a housing and a blade holder positioned within the housing wherein the blade holder is movable in a direction along a length of the housing. The device also comprises an actuator positioned within the housing and associated with the blade holder to move the blade holder along the length of the housing wherein the actuator moves parallel to the blade holder within the housing. Another embodiment of the blade holding device comprises a housing and a blade holder wherein the blade holder is adapted to move in a direction within the housing. It also comprises an actuator associated with the blade holder to move the blade holder in the direction and a coupling arm secured to one of the blade holder and the actuator, wherein the coupling arm comprises an end for making a contact with the one of the actuator and blade holder which is not secured to the coupling arm and wherein the actuator is adapted to transmit a force to the blade holder through the contact and to move the blade holder in the direction. The device further comprises a control surface connected to a rearward end portion of the housing, wherein the control surface is positioned in a direction nonparallel to the direction, wherein the control surface is associated with the coupling arm to enable the coupling arm to move in a direction nonparallel to the direction to position the end to make the contact with movement of the actuator toward a forward end portion of the housing.
