Patent ID: 6928903

Claim:
A wrench comprising a handle; a base connected pivotally to the handle and having a bottom; a disk having a top and a bottom; a hollow sleeve formed on and protruding from the top of the disk and having a distal end; a proximal end; an inside surface; an outside surface being non-circular; a longitudinal hole; an inner annular groove formed in the inside surface of the longitudinal hole near the proximal end; and an eye connected to the bottom of the disk and connected pivotally to the handle; a rotating device having a pawl ring mounted around the sleeve of the base and having; a distal edge; a proximal edge; an inside surface; a hole formed axially through the pawl ring, being non-circular, corresponding to the outside surface of and mounted around the sleeve on the base; multiple teeth formed on and extending longitudinally from the distal edge of the pawl ring; and a spring mounted around the sleeve of the base and between the pawl ring and the disk of the base; a plug mounted rotatably in the longitudinal hole in the sleeve of the base and having a proximal end; a distal end; a non-circular hole formed longitudinally in the plug from the distal end; an outer annular groove formed around the plug near the proximal end of the plug and aligns with the inner annular groove in the sleeve of the base; and at least one detent formed in the non-circular hole; and a C-clip mounted simultaneously in the inner annular groove in the sleeve of the base and the outer annular groove in the plug of the rotating device; and a bidirectional device having a ratchet ring engaging with the teeth on the pawl ring of the rotating device and having: a counterclockwise end; a clockwise end; multiple counterclockwise ratchets formed respectively on and extend from the counterclockwise end of the ratchet ring, wherein each counterclockwise ratchet has a perpendicular face and an inclined face, and the inclined faces of the counterclockwise ratchets extend in a same direction; multiple clockwise ratchets formed respectively on and extend from the clockwise end of the ratchet ring, wherein each clockwise ratchet has a perpendicular face and an inclined face, and the inclined faces of the clockwise ratchets extend in a direction same as the direction of the inclined faces of the counterclockwise ratchets; and a locking through hole formed axially through the ratchet ring and corresponding to the non-circular hole in the plug; and a non-circular shaft mounted through the ratchet ring corresponding to the locking through hole in the ratchet ring, extending into the plug of the rotating device and having two opposite ends; at least one longitudinal surface; and two positioning devices installed respectively on opposite ends, protruding radially out from the shaft, aligned longitudinally on the longitudinal surface and connect the plug to a tool socket.
