A device is capable of collecting dust and drawing dust and is provided with a machine tool mounted thereon and externally connected with an extension tube. The device comprises a fixation seat for mounting the machine tool which has a first opening, and a second opening; a vacuum cleaner mounted in the interior of the fixation seat; a first window disposed slidably at the first opening of the fixation seat; a second window disposed slidably at the second opening of the fixation seat. By controlling the first window to remain open and the second window to remain close, the vacuum cleaner removes the dust produced by the machine tool. On the contrary, by controlling the first window to remain close and the second window to remain open, the second opening removes dust in other areas via the extension tube.
