An assembly for a subterranean tool, comprising:
- a fixed component of the tool;
- a selectively movable mandrel component of the tool movable to a first position relative to said fixed component;
- a lock assembly operably engaged to said components to lock said components to each other when said movable component is in said first position;
- said movable component capable of further movement from said first position for release of said components by said lock assembly in a second position, said further movement also configuring said lock assembly to again lock said components to each other when said movable component is returned to said first position;
- said movement of said movable component to said first position to engage said lock assembly and said further movement of said movable component from said first position to release said components is repeatable and axial without rotation.
