Multi-selective micro manipulator

A multi-selective micromanipulator comprising:

• an actuator including a shaft;
• a main mover which is connected to the shaft and, moves linearly or rotationally with respect to the shaft by the actuator;
• a driving means which moves the main mover;
• a projection which is formed on the main mover;
• and
• a plurality of submovers which are aligned radially around the shaft,
• wherein the projection selectively contacts with the plurality of submovers depending on the movement of the main mover,
• wherein a selected submover is linearly moved by the projection in a direction parallel to the axis direction,
• wherein:
• the main mover has a cylindrical shape,
• the driving means includes a guide groove formed at a surface of the main mover, and a first guide pin which may be engaged with the guide groove,
• the guide groove comprises a plurality of first inclined grooves formed to be inclined right downwardly with respect to a length direction of the shaft, and a plurality of second inclined grooves formed to be inclined left downwardly with respect to the length direction of the shaft,
• the first inclined grooves and the second inclined grooves are alternately aligned at the side surface of the main mover, and
• a first inclined groove and a second inclined groove adjacent to each other are connected to each other to form a sawtooth-shaped guide pin path.
