The invention provides an electric rotation operating tool. The electric rotation operating tool comprises a power source assembly, a shell, a speed reducing motor, a fixing sleeve, a motive power output barrel and a reversing switch. A first end and a second end are oppositely disposed on the shell; the power source assembly is fixedly connected with the first end; the end, far away from an output shaft, of the speed reducing motor extends along the second end into the shell to be fixed and is electrically connected with the power source assembly; the speed reducing motor is disposed in the fixing sleeve and fixedly connected with the second end of the shell through the fixing sleeve; the motive power output barrel is fixedly connected with the output shaft of the speed reducing motor androtationally connected with the end, far away from the shell, of the fixing sleeve; and the reversing switch is disposed on the shell, electrically connected with the speed reducing motor and the power source assembly and used for controlling the speed reducing motor to rotate forwards and backwards. The electric rotation operating tool can assist in manual work for finishing rotation of an insulating rod, the working efficiency is improved, and thus the purposes of saving time and labor and reducing cost are achieved.
