People recognize the huge consumption of the use of pencil to timber very early, have invented the pencil that does not use timber, as propelling pencil for this reason.But the problem that propelling pencil exists is exactly that cost of manufacture is than higher, the situation of lead for retractable pencil waste is serious (lead for retractable pencil also has very big adverse effect to environment) relatively, do not meet people's use habit, therefore propelling pencil is not widely used, and traditional Wood pencil has still occupied the staple market share.

The utility model content

In order to solve the big problem of conventional wooden pencil timber consumption, the utility model provides a kind of novel pencil, has reduced the consumption of pencil timber, and is simultaneously with low cost.

The technical solution of the utility model is:

A kind of novel pencil, comprise the hollow shaft of a writing brush of an end opening, the described shaft of a writing brush is metal material or plastic material, and is arranged on the Wood pencil in the described shaft of a writing brush, the writing end of Wood pencil stretches out from described shaft of a writing brush openend, and the internal diameter of described shaft of a writing brush openend is equal to or greater than the external diameter of Wood pencil; The diameter of the lead for retractable pencil of described Wood pencil is smaller or equal to 1.8 millimeters, the wood pen holder of Wood pencil is cylindrical penholder, external diameter is smaller or equal to 4.4 millimeters, or the wood pen holder of Wood pencil is hexagonal prismoid shape penholder, and the distance between prismatic relative two faceted pebbles is smaller or equal to 4.4 millimeters.

The other end of the described shaft of a writing brush is a blind end, and the shaft of a writing brush wall of contiguous blind end is provided with fill-up hole.

Blind end at the shaft of a writing brush is provided with rubber.

Technique effect of the present utility model:

The utility model is because the volume of wood pen holder is few than the amount of wood of the penholder consumption of traditional Wood pencil, the radial dimension that surrounds the shaft of a writing brush of the utility model Wood pencil simultaneously can be provided with to such an extent that be suitable for controlling of all ages and classes staff, and the shaft of a writing brush is with low cost, has realized the purpose of this utility model.The utility model pencil can not cause a large amount of wastes of lead for retractable pencil simultaneously, meets people's use habit.

Another benefit of the present utility model is that the consumption along with Wood pencil shortens; can at any time Wood pencil be extracted out from the openend of the shaft of a writing brush; because the shaft of a writing brush can not change length; just being suitable for the length that staff controls can not change; even Wood pencil very short also can the continuation that become used like this; the phenomenon that (pencil of this moment also has bigger length) just goes out of use when being shorter in length than staff when having avoided using traditional pencil and controlling length has been protected consumer's interests.

Therefore, the utility model has been protected the interests of consumer and manufacturing enterprise, and the growth in protection forest zone has produced the social benefit of protecting environment, and the offspring benefits future generations.
