Embodiment Construction
[0009] In the figure, when the helical wire (1) is heated or cooled, it is confined within the confinement frame (2). Since the telescopic ends (3) and (4) of the helical wire are free movable ends, a large displacement can be achieved, and the purpose of driving some mechanical parts can be achieved by using this displacement.
[0010] One of the telescopic ends (3) and (4) of the above-mentioned helical wires can be fixed to achieve or obtain a larger displacement.
