Abstract
The present invention provides an apparatus for moving a member including a first clamp assembled to a fixed surface for selectively clamping the member and a second clamp moveable with respect to the first clamp for selectively clamping the member. A piezo actuator is disposed between the first and second clamps for moving the member in response to expansion of the actuator. Resilient means bias the second clamp toward the first clamp.
