Abstract (en)
[origin: WO9936229A1] A two headed ratcheting driving wrench (10). Each head (12 or 104, 106) has a rotatable receptacle (26) constrained to rotate in only one direction by interengaging teeth (22) formed on the receptacle (26) and in the head (12). Both sets of teeth may be pointed or rounded. The receptacle (26) and its surrounding chamber formed in each tool head (12 or 104, 106) are dimensioned and configured to assure engagement between receptacle (26) and head (12 or 104, 106) when placed under torque in one direction. The wrench (10) has a handle (14) having a significant portion of its length offset from linear to allow for working in tight quarters. The receptacle (26) has a square hole (28) formed therein for receiving a driven tool (50). In another option, the square tool (50) is separate from the driven tool. Optionally, the drive system has provision for limiting torque acting on the driven member.
