A probe retraction tool including a threaded split shaft connected to a packing gland in coaxial relation to a probe inserted therein. The shaft has a longitudinally coextensive slot and axial bore within which the longitudinal axis of the shaft extends in parallel relation thereto. A spinner nut is threadably connected to the shaft and has a slip ring concentrically mounted thereon for relative rotational movement. A member for securing the probe to the spinner nut is connected to the slip ring and extends within the channel to detachably connect with an upper end of the probe. A handle is connected to the spinner nut for rotating the same, thereby urging the spinner nut, the slip ring and the probe in coaxial vertical movement along the longitudinal axis of the split shaft.
