<p>Disclosed is an adjustable length adapter which incorporates a driving motor on the inside and is coupled with a rotation tool at one side, wherein a rotation shaft is protruded from the rotation tool and rotates when the driving motor is driven. The adjustable length adapter includes: a coupling member formed with a through-hole at one side to be penetrated by the rotation shaft of the rotation tool so as to be coupled at one side of the rotation tool; a main body having a supporting member formed at the other side of the coupling member; a varying section of which one side is coupled with the supporting member to be withdrawable therefrom and the other side is formed with a rotation shaft to be coupled with an exchangeable working member; a driving pulley disposed on top of the main body and coupled with the rotation shaft of the rotation tool; a driven pulley coupled with the rotation shaft of the varying section; and a belt coupled between the driving pulley and the driven pulley for rotating the driven pulley when the rotation shaft protruded from the rotation tool rotates. According to the adjustable length adapter of the present invention, the main body coupled at a side of the rotation tool is coupled with a varying section, which is coupled with a working member such as a cutting blade or the like, in such a manner that the length of the varying section is adjustable so that the length is adjusted according to the state of an object, thereby enabling easy machining of the object.</p> |
