The present invention provides an electric paper punch (hole puncher) with a reinforcement mechanism. The paper punch comprises a module with a paper slot and punch pin, an axle, a connecting module connected to the punch pin, and a motor. The connecting module has a rear wall that is arc-shaped and works in conjunction with an eccentrically shaped wheel to drive the punch pin forward and backward as the eccentrically shaped wheel rotates within the wheel groove. The arc-shaped wall of the connecting module is reinforced to prevent distortion from repeated pressure exerted during movement of the punch pin.
