发明名称 EXPANDABLE COUNTER-TORQUE WRENCH
摘要 A counter-torque wrench includes a tubular outer body having distal and proximal ends and an inner shaft disposed within the outer body. The inner shaft has a proximal end and a distal end and is axially displaceable relative to the outer body. The distal end of the inner shaft has a gripping end portion disposed proximate to the distal end of the outer body. The gripping end portion comprises a plurality of branches extending distally of the outer body. The branches are radially displaceable between a relatively open position, in which the branches are displaced radially outwardly from one another, and a relatively closed position, in which the branches are displaced radially inwardly toward one another. The distance between the branches is greater in the open position than in the closed position. A method of using the counter-torque wrench is also provided.
