Locking push-pull fastener assembly

A precision adjustment fastener mechanism comprising:

• a base having a first aperture for receiving a clamping fastener;
• a platform comprising a second aperture having one or more inner threads;
• a locking push-pull fastener assembly disposed within the second aperture, the locking push-pull fastener assembly comprising:
• a clamping fastener having a portion positioned in the first aperture;
• a sleeve having a third aperture extending along a axis of the sleeve, wherein the clamping fastener is positioned within the third aperture, the sleeve comprising:
• a first portion and a second portion, the first portion moveable relative to the second portion along the axis, the first portion comprising one or more outer threads operable to interface with the one more inner threads of the platform, and the second portion comprising one or more outer threads operable to interface with the one more inner threads of the platform;
• and
• an axial displacement portion separating the first and second portions, the axial displacement portion transmitting a torque along the axis between the first and second portions, and facilitating movement of the first and second portions relative to one another to bind the one or more threads of the outer surfaces of the first and second portions with the one or more inner threads of the platform to axially lock the sleeve to the platform upon the sleeve being subject to an axially compressive force by the clamping fastener.
