[0002] Wooden and paper roll pencils bring convenience to people's work and study, but at the same time consume a lot of valuable forest resources
Existing wooden and paper-rolled pencils need to be rolled and sharpened and the pen core can be sharpened to write. When the pen is used to 6-7cm, it is often thrown into the trash can because of the inconvenience of holding the pen. The rolled paper, Sawdust cannot be recycled, causing a lot of waste, and the exposed pencil lead is easy to break

The invention provides a pencil with an adjustable pencil lead and belongs to the technical field of pencil making. The pencil comprises a pencil holder, the pencil lead, a pencil point sleeve and a pencil plug. A pencil lead propeller is arranged in a cavity of the pencil holder. The pencil is characterized in that a protruding block is arranged on the side wall of the upper end of the pencil lead, the pencil lead propeller is composed of a spiral pipe and a rotary handle arranged at the upper end of the spiral pipe, and the rotary handle is connected to the upper end of the spiral pipe through a columnar connecting block; the pencil lead is arranged in an inner cavity of the spiral pipe, the protruding block is arranged in a gap between two adjacent spiral rings of the spiral pipe, and the spiral pipe and the pencil lead are coaxial; and the spiral pipe is rotationally connected into the inner cavity of the pencil holder through a columnar connecting block, the rotary handle is arranged outside the upper end opening of the pencil holder, rail grooves matched with the protruding block are axially formed in the inner wall of the pencil holder, and the protruding block is arranged in the rail grooves. The pencil is ingenious in conception, simple in structure, easy to produce and manufacture, low in cost, free of lead breakage, high in utilization rate of the pencil lead, capable of saving resources and assisting a user in grasping a correct pencil holding posture and environment-friendly, and has wide market space.
Description
technical field [0001] The invention relates to a pencil structure with an adjustable refill, which belongs to the technical field of pen making. Background technique [0002] Wooden and paper roll pencils bring convenience to people's work and study, but consume a large amount of valuable forest resources at the same time. Existing wooden and paper-rolled pencils need to be rolled and sharpened and the pen core can be sharpened to write. When the pen is used to 6-7cm, it is often thrown into the trash can because of the inconvenience of holding the pen. The rolled paper, Sawdust cannot be recycled, causing a lot of waste, and the exposed pencil lead is easy to break. Therefore, there is a need for a pencil with a continuous core, high utilization rate of the pen core, resource saving, and environmental protection. Contents of the invention [0003] The object of the present invention is to provide a pencil with an adjustable refill that can improve the utilization rate ...
