[0002] Pencil is a kind of cultural school supplies commonly used by people; it is reported that my country provides 6 to 7 billion pencils to the world market every year, and is the world's largest exporter of pencils; pencils are indispensable school supplies in people's daily life. It is used by students or office workers; the existing plastic pencils are mostly composed of refills, pen holders and wrapping layers wrapped outside the pen holders. The existence of the wrapping layer makes the use of pencils more comfortable, etc.; but the existing pencil wrapping Paper or commonly used plastic film is used for multiple layers. Traditional paper or plastic film will cause damage to the wrapping layer due to long-term friction when the user holds it for a long time; comfort, and may even damage the skin of the hand-held part, and the existing plastic wrap layer will emit a plastic smell after long-term use, which affects the experience of using plastic pencils; at the same time, the existing plastic pencils are usually covered with paper or plastic layers for aesthetics. The exterior is painted, and the paint surface will fall off after a long time of use
