摘要

The present invention relates to a color core drawing device and a rotary drawing color pencil. The color lead extraction device includes a head ring and a coupling ring fitted to the body of the colored pencil, and a head coupling nut portion formed on the inner circumferential surface of the head coupling portion and a coupling ring bolt portion formed on the outer circumferential surface of the coupling ring are screwed together. The rotating drawer colored pencil includes a head portion and a body portion, and the head coupling nut portion formed on the inner peripheral surface of the head coupling portion of the head portion and the body coupling bolt portion formed on the outer peripheral surface of the body coupling portion of the head portion are screwed together. Accordingly, it is possible to provide a color extraction device and a rotational drawing color pencil excellent in practicality, economy and environmental friendliness with a simple structure.
