Abstract (en)
A handle member (12) terminates in an expandable yoke containing a fixed upper half (16) and an expandable lower half (18) for movement from an expanded open position for receiving a socket (24) to a closed position in driving engagement with the socket. A curved rib is formed transversely on the inner surface of each yoke half. A split ring-like nut driving socket (24) contains exterior ratchet teeth and a circular bore formed transversely through the socket with a recessed counter bore forming a circular guide channel received in rotational engagement with the curver ribs of the yoke halves (16, 18). The socket contains a curved head having lands which in combination define a polygonal wrench opening. A pawl mechanism (60) mounted on the wrench handle member is resiliently biased into engagement with the ratchet teeth.
