ABSTRACT:
A ratchet tool comprises a tubular body (1) with a handle (2) at one end and a ratchet drive (3) at the other end. The handle mounts a lever mechanism (12) which is operatively connected to the ratchet drive (3) by a plunger (4), a gear mechanism (7) and a flexible member (8). When the lever mechanism (12) is operated linear movement of the plunger (4) translates through the gear mechanism (7) and the flexible member (8) into rotary motion of the ratchet drive (3). With the lever mechanism (12) removed the ratchet tool can be used as a conventional ratchet.
