An electric stapler includes a base and a press portion articulated to the base. The press portion is provided with, from down to up, a staple channel assembly configured to receive a staple, a staple pressing plate assembly configured to press the staple and a drive assembly in sequence. The position of the drive assembly is fixed relative to the press portion. The staple channel assembly and the staple pressing plate assembly are rotatable relative to the press portion. The drive assembly includes a power unit and an execution component connected to the power unit to press or raise the staple pressing plate assembly. The above electric stapler addresses the technical issues that the staple channel cannot reset automatically after the staple is stuck and it is difficult to clear away a failed staple.
