A multi-functional feed-screw-type dovetail stage may include a male threaded rod having, on each of its ends, a coupling portion for coupling to a control knob; a first support and a second support provided on respective sides of a fixed member for rotatably supporting the male-threaded rod; and the control knob that detachably couples via its coupling portion to the male-threaded rod and serves to rotate the male-threaded rod. A slide member travels until a female-threaded cylinder engaging the fixed member abuts the first support and the second support upon moving. |
