Patent attributes
A hollow rod developable actuator tool including a first link comprising an outer cylinder, a deployment ring including second link comprising a first portion pivotably connected to the first link at a first joint mounted in a first cavity in the wall of the outer cylinder and a third link comprising a second tool portion pivotably connected to the first portion at a second link, and a fourth link comprising an inner cylinder to which the second portion of the deployment ring is also pivotably connected at a third link mounted in a second cavity in the wall of the inner cylinder. When the inner cylinder of the fourth link is rotated in relation to the outer cylinder of the first link the actuator tool transitions from a first state where the deployment ring is stowed within the tool to a second state where the deployment ring is deployed externally.
