Zusammenfassung:	The utility model relates to a multifunctional electric screw fastening tool which comprises a shell, a motor, a battery, an illuminating lamp, a corner tool head and a control circuit. A battery anode wire is divided into four paths, one path is connected with a normally-open button I, a relay II normally-closed switch and a relay I coil and then is connected with an illuminating lamp, the other path is connected with a normally-open button II, a relay I normally-closed switch and a relay II coil and then is connected with the illuminating lamp, and the illuminating lamp is connected with a battery cathode. The third path is connected with a first normally-open switch of a relay I, a sliding resistance adjusting module, a motor and a second normally-open switch of the relay I and then connected with a battery cathode, and the fourth path is connected with a first normally-open switch of a relay II and then connected between the motor and the second normally-open switch of the relay I; a lead-out line between
