A conversion ratchet drive (10) for use with socket wrenches having various sizes of ratchet receptors, the ratchet (10) being provided with at least one output shaft sleeve (30) for effectively adjusting the side length thereof. The ratchet (10) is provided with an output shaft (16) which extends from the same side of the ratchet head (14) as each of the output shaft sleeves (30). The ratchet (10) includes a conventional handle (12), a conventional ratchet pawl (24), an output shaft (16), and at least one output shaft sleeve (30). Each output shaft sleeve (30) defines a square cross section with an inner wall (36) dimensioned to closely receive the output shaft (16) or a smaller sleeve (30), and an outer wall (38) dimensioned to be closely received within a socket wrench ratchet receptor or a larger sleeve (30). A base (46) is provided with each sleeve (30) for limiting the distance that sleeve (30) may be extended from the ratchet head (14). The base (46) is further used to eject the sleeve (30) from the ratchet head (14). A locking mechanism (20) is provided for locking the position of each sleeve (30) with respect to the output shaft (16) or the previous sleeve (30). A second locking mechanism (44) is provided for securing a socket wrench (26) to the sleeve (30).
