An electric eraser comprising a housing (3). A motor (5), a battery (7), and a sleeve cylinder (2) are mounted within the housing (3). An eraser tip (1) is fixed by the sleeve cylinder (2). A control button (4) is provided on the housing (3). The motor (5) is a stepper motor. A control circuit (6) is fixed at the front extremity of the battery (7). The stepper motor (5) is arranged in front of the control circuit board (6). The structure allows the motor (5), the battery (7), and the control circuit board (6) to be tightly assembled together, reduces wiring and unreasonable spaces, allows effective utilization of space, reduces energy consumption, and reduces power consumption. |
