ABSTRACT:
An elongate engagement tool that has engagement elements located on a distal end of a first rod, a handle on the proximate end of second rod, a controller on the handle to control the engagement elements, and a linkage between the controller and engagement elements to control the engagement elements is disclosed. The rods are connected together by a locking hinge. A locking pin is received by the knuckles of the hinges has a plurality of axial segments. The profiles of the axial segments alternate from round disks to aster shaped disks that closely fit into the apertures formed by the knuckles. When the locking pin is moved to a first locked position where the aster shaped profiled sections are aligned with the apertures in the corresponding knuckles to the hinge is locked. Movement of the pin to a second free position where the round axial sections are aligned with the apertures in the knuckles provides for limited rotational movement.
