Actuator

An actuator comprising:

• a supporting frame having a movable element accommodation space, at least one first elastic element accommodation space and at least one first electrically-driven element accommodation space;
• a movable element received by the movable element accommodation space of the supporting frame, at least one second elastic element accommodation space and at least one second electrically-driven element accommodation space being arranged in proximity to each other around an exterior thereof;
• an electrically-driven element received by the at least one first electrically-driven element accommodation space of the supporting frame and the at least one second electrically-driven element accommodation space of the movable element and configured to enable the movable element to move along at least one axis;
• and
• an elastic element configured to provide an elastic force with respect to at least one axis, wherein the elastic element is received by the at least one first elastic element accommodation space of the supporting frame and the at least one second elastic element accommodation space of the movable element and able to perform a sliding function with the at least one second elastic element accommodation space of the movable element.
