ABSTRACT:
A power-driven hand tool including a housing having first and second housing parts having first and second coaxial openings therethrough. A driving element is movably positioned between the housing parts and has a third opening in coaxial alignment between the first and second openings. A motor is mounted on the housing and connects through a motion-transfer device to the driving element for causing angular oscillation thereof about a tool-driving axis. An annular socket-driving member is rotatably supported within the first opening and has a bore therethrough coaxial with the axis for releasably but drivingly engaging a removable socket. The socket-driving member has a gear rotatably positioned in the third opening. First and second pawls are mounted on the driving element for engagement with the gear for respectively causing rotational driving movement of the socket in opposite first and second directions. A reversing member cooperates with the pawls and is movable between first and second positions for respectively permitting solely the first and second pawls to be drivingly engaged with the gear.
