The electric tool comprises a bracket for supporting the electric motor and handles attached to handle-mounting sections of the bracket for keeping the electric tool in cutting operation. Also included in the electric tool is a coupling mechanism for mechanically coupling each of the handles to each of the handle-mounting sections of the bracket. The coupling mechanism includes first and second annular members which are respectively attached to the handle-mounting section thereof and the handle so as to be coaxially arranged in confronting relationship to each other. Each of the first and second annular members has elongated recess portions and elongated projection portions which are alternately and successively arranged at a predetermined angular interval with respect to its own center. The elongated recess portions and projection portions of the first annular member are arranged to be engaged with the elongated projection portions and recess portions of the second annular member so as to provided a desirable mounting angle of the handle with respect to the bracket.
