Claim 13:
14. A hollow rod developable actuator tool, the tool comprising:
a first link comprising an inner cylinder, the inner cylinder comprising:
a first end having a first aperture;
a second end having a second aperture;
a first wall extending between the first end and second end defining an inner circumference of the hollow rod and a central passage therethrough from first end to the second end; and
a first cavity in the first wall having a first joint;

a first tool mechanism comprising:
a second link comprising:
a first end pivotably connected to the wall of the first link at the first joint;
a second end having a contact area;
a body extending between first end and second end; and
a second joint offset from the second end of the body of the second link;

a third link comprising:
a first end pivotably connected to the second joint of the second link;
a second end pivotably connected to a third joint; and
a body extending between the first end and second end;

a fourth link comprising an outer cylinder, the outer cylinder comprising:
a first end having a first aperture;
a second end having a second aperture,
a second wall extending between the first end and second end defining an outer circumference of the hollow rod and a central passage therethrough from first end to the second end; and
a second cavity in the second wall having the third joint;

a second tool mechanism comprising:
a fifth link comprising:
a first end pivotably connected to the wall of the first link at the first joint;
a second end having a contact area;
a body extending between first end and second end; and
a fourth joint offset from the second end of the body of the fifth link; and

a sixth link comprising:
a first end pivotably connected to the fourth joint on the fifth link;
a second end pivotably connected to the third joint of the fourth link; and
a body extending between the first end and second end;

wherein, when the inner cylinder the first link is rotated in relation to the outer ring of the fourth link, the actuator tool transitions from a first state wherein first tool mechanism and second tool mechanism are contained within the cavities of the walls to a second state where the first tool mechanism and second tool mechanism extend outside the outer circumference of the hollow rod.
