A sleeve with an indication assembly comprises a sleeve; and a toggle having an inner diameter corresponding to an outer diameter of the sleeve; and the toggle being made of aluminum alloy; a surfaces of the toggle being anodic processed so as to form with a protection film of different colors; thus the surfaces of the toggle is prevented from cracking, collision, mist and falling off. Furthermore, in another case, the toggle has an inner diameter corresponding to an outer diameter of the sleeve; and the toggle is made of iron. A surface of the toggle is electroplated so as to form with a copper layer and then is performed with anodic processing so as to have the effect of indication of sizes. |
