发明名称 Wrench extension tool
摘要 A wrench extension tool having a gear train of intermeshing idler gears contained within an inner housing formed of two (2) curved and substantially parallel plates. Aligned pairs of bores are provided through the parallel plates providing residence for axle pins about which the idler gears rotate. At each end of the wrench extension tool is a socket opening in which there resides an end gear. Each end gear includes a journal portion extending therefrom with the socket opening serving as bearings for such journals. Each end gear includes a hexagonal socket receptacle into which interchangeable driven and drive sockets can be inserted by a user. A locking mechanism is provided to retain the chosen drive and driven sockets in the socket receptacles. In such manner, a relatively narrow wrench extension tool is provided where either end of the wrench extension tool can serve as the driven end and either end can serve as the drive end.
