A multi-DOF of positioning device has a main base, a fixed base, a translational Y-axial element, a translational X-axial element, multiple spring-mounted electromechanical actuating units, an elevating device, a rotational angle-adjusting assembly and an optical fiber holder. The translational Y-axial element is moveably mounted on the fixed base along a first axis. The translational X-axial element is moveably mounted on the translational Y-axial element along a second axis. The elevating device is moveably mounted on the main base along a third axis. The spring-mounted electromechanical actuating units are used to translationally move the fixed base, the translational Y-axial element and the elevating device relative to the corresponding structure along one of the axes. The rotational angle-adjusting assembly is mounted on the translational X-axial element and having a capability of rotating relative to the first, the second and the third axes.
