Abstract
An internal pipe gripping tool includes a tool body adapted for insertion into a pipe. A gripper is disposed adjacent and movably coupled to the tool body. The gripper has an engaged position and a released position relative to the tool body. A lever has a first end node, a second end node, and an intermediate node between the first and second end nodes. The first end node is coupled to the tool body, and the intermediate node is coupled to the gripper. A force applied to the second end node results in another force at the intermediate node that shifts the gripper from the engaged position to the released position.
