According to the present invention, the plurality of actuating arms engaged with each of the plurality of blade bodies are sequentially rotated in a stepwise manner by the plurality of interlocking pins that are differentially rotated by the rotation of the rotation shaft. As a result, each blade body is differentially advanced toward the paper sheet by each of the actuating arms, and a plurality of binding holes can be reliably punched in the paper sheet in a step-by-step manner. In addition, since the blade advances through the operating arm using a differential interlocking pin, the number of parts is small and the structure is simple.Furthermore, since the electric motor is powered by a battery, it can be used in any location where there is no commercial power source. Therefore, it is possible to provide an electric punch that can reliably solve cost and usage problems compared to conventional punches and is easy to handle.
