Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pencils, in particular to a pencil with a safety protection function. Background Art
[0002] A pencil is mainly composed of a pencil lead and a pen holder. It is a type of pen used for writing and drawing sketches. The pen holder is generally made of wood, while the pencil lead is mainly made of graphite. During production, the pencil lead is pressed down by a wooden pen holder. The graphite used for the pencil lead is relatively low in hardness and is brittle. Therefore, it is easy to break after falling, resulting in the inability to use it normally. A new pencil needs to be replaced, which causes waste.
[0003] China Patent Authorization Announcement Number: CN 208993344 U, Authorization Announcement Date June 18, 2019. This utility model relates to an anti-fall pencil, including a refill and a pen holder, the pen holder is coated on the outside of the refill, and is characterized in that the pen holder includes a first coating layer, a protective layer, and a second coating layer sequentially coated from the inside to the outside, the protective layer is a structural member made of a soft material, and the second coating layer is a hard structural layer.
