Bidirectional torque wrench

摘要: A bidirectional torque wrench includes a main body pivotally fixed thereon with an operating rod, and at least two resisting units are equiangularly symmetrically assembled the circumferential side of rod. By so designing, in process wrench, lateral forces acting on opposite direction able to be offset mutually prevent from shifting eccentrically for stabilizing torsion output, lower force received by one single unit greatly enhance maximum value that can output.
