Abstract
A ratchet wrench is provided which includes a ratchet head having a part-cylindrical surface with head teeth thereon and an elongated handle hingedly coupled to the head. The handle has first and second handle ends, an axis extending between the ends and an axial first bore opening at the first handle end. The wrench also includes a rod disposed in and moveable within the first bore between an engaged condition engageable with the head teeth for locking the head in a selected position relative to the handle and a non-engaged condition disengaged from the head teeth and accommodating relative movement of the head and handle, and biasing structure for biasing the rod to the engaged condition. The wrench also includes retaining structure coupled to the rod for retaining the rod in its non-engaged condition. The retaining structure may be disposed at several locations relative to the ratchet head.
