发明名称 P-handle extraction tool
摘要 The present invention is directed to a P-handle extraction tool for removing and/or installing a tubular member when access to the external surface of the tubular member is restricted. The tool uses a P-shaped handle to orient the grip of the tool approximately perpendicular to the longitudinal axis of the tubular member to be removed or installed that is engaged by the tool. Thus oriented, the tubular member is rotated by rotating the grip about the axis of rotation of the tubular member. The handle design also provides for the attachment of a torque arm, thereby allowing the user to generate additional torque necessary to remove tightly fitted tubular members.
