Abstract
A ratchet tool includes a head and a shank extending from the head in which a ratchet and a pawl are received in the head. A rod is rotatably inserted in the the shank and a grip is connected to the distal end of the shank. The grip is detachably connected to the first end of the rod, and an actuating member is connected to the second end of the rod. The actuating member is engaged with the ratchet which is rotated by the actuating member by rotating the grip. Therefore, the ratchet together with a bit or a socket connected to the ratchet are rotated simply by rotating the grip.
