Abstract
A ratchet socket tool includes a socket having a toothed protrusion extending axially from an end thereof and a tube is mounted on the first end of the socket. A driving member rotatably inserts into the tube and has a passage defined axially therethrough and a recess is defined in an inner periphery of the passage so that a pawl is movably engaged with the recess and has a toothed surface for being engaged with the toothed protrusion of the socket. A biasing member has a first end engaged with a notch defined in an inner periphery of the tube and a second end of the biasing member extends through a hole defined through a wall of the driving member and engaged with a concavity in the pawl so as to push the pawl to engage with the toothed protrusion.
