<p>A hand-held socket driver has a handle (14) terminating in a ring socket. The ring socket holds a drive peg (16) with a reversible ratchet gear, which further has an external secondary ring array of gear teeth (20a). The handle accepts an external sleeve with a proximal end and a distal end. The distal end has gear teeth that engage with the teeth (20a) for twist-rotation around the handle (14) axis.</p> |
