Abstract
A mechanism for adjusting the relative angular orientation between two coaxial components includes a housing, a mandrel disposed in the housing, a lower ratchet member disposed around the mandrel, wherein a lower engagement interface between the lower ratchet member and the mandrel restricts relative rotation between the lower ratchet member and the mandrel, an upper ratchet member disposed around the mandrel, wherein an upper engagement interface between the upper ratchet member and the mandrel restricts relative rotation between the upper ratchet member and the mandrel, and a central sleeve disposed around the mandrel, wherein an outer engagement interface between the central sleeve and the housing restricts relative rotation between the central sleeve and the housing, wherein the central sleeve has an upper position configured to transmit torque between the upper ratchet member and the housing and a lower position configured to transfer torque between the lower ratchet member and housing.
