Description: |
| An apparatus is disclosed for linearly displacing a rotatable spindle relative to an object. The apparatus includes a support that is connectable to the spindle such that translation of the spindle relative to the support in a first direction is restrained, a rotatable shaft which is connected to the support such that translation of the shaft relative to the support in the first direction is restrained, and a rotational drive system rotatably connected to the shaft and rotatably connectable to the spindle, to transmit rotational drive from the spindle to the shaft. The apparatus also includes a contact piece eccentrically mounted to the shaft, wherein the contact piece has a contact surface thereon for contact with the object. Rotation of the shaft varies a distance, measured in the first direction, between the support and a portion of the contact surface contacting the object, such that the spindle is linearly displaceable relative to the object. |
