ABSTRACT:
A double-acting wrench has a main handle and a holding handle, the end of the main handle being connected to a set of reversing gears, and through a ratchet and double pawls to the cage in which the set of reversing gears are mounted. The reversing gears, or the cage in which they are mounted, are selectively connected to a tool driver. Ratchets and double pawls are engageable so that rotation of the main handle in either clockwise or counterclockwise direction with respect to the holding handle will produce continuous clockwise or counterclockwise rotation of the tool driver.
