Abstract

The utility model relates to an electric pliers structure mainly comprising a shell whose bottom end is combined with a power supply device. The power supply device is electrically connected with a controlling switch convexly exposed out the shell by a conducting wire and connected with a motor positioned in the shell by another conducting wire to enable the controlling switch to control the switching of the motor. The outputting axle of the motor is connected with a speed reducing gear set whose outputting end is connected with a rotating plate extending an eccentric axle rod. The eccentric axle rod is closed with the blocking board of a knife tool movable arm and the blade of the knife tool is convexly exposed out the shell. When the motor is activated, the outputted rotating speed can enlarge the outputted torque force by the speed reducing gear set in order to drive the rotating plate on the outputting end of the speed reducing gear set to rotate to drive the eccentric axle rod on the rotating plate to conduct simultaneous circular moving. The movable arm of the knife tool conducts repeated vertical moving by the poking of the eccentric axle rod to obtain the purpose of pliers cutting.
