Abstract

An energy-storage pen implement includes a base, a spiral knife assembly, a rotating plate, an elastic device and a pressing block. The base includes a first groove and a second groove, and the first groove is provided for inserting a pen implement. The spiral knife assembly is disposed at the first groove. The rotating plate is disposed at the first groove and connected to the spiral knife assembly. The elastic device is disposed at the second groove. One end of the pressing block is connected to the rotating plate, and another end of the pressing block is connected to the elastic device. When the elastic device moves resiliently to push the pressing block, the pressing block drives the rotating plate and the spiral knife assembly to rotate, thereby allowing the spiral knife to sharpen the tip of the pen implement.
