Embodiment Construction

[0010] In the figure, the penholder is made up of a penholder part 1 and a penholder head 5. The center of the pen shaft part 1 has a lead groove 3 running through it longitudinally, and a series of equally spaced transverse compartments 4 are distributed on the pen shaft part 1 at the same time, and the transverse compartments 4 are perpendicular to the lead groove 3 cross. In addition, prepare a circular insert 2 that can be tightly inserted into the transverse compartment 4

[0011] When in use, insert the lead core 6 into the lead groove 3 of the pen shaft, so that the lead core 6 is exposed to an appropriate length from the head 5 of the pen shaft, and then insert a circular insert 2 into a suitable transverse compartment 4 , the lead core 6 can be fixed.

[0012] The penholder made up of the penholder part 1 and the penholder head 5 can be reused, so it is not necessary to consume a large amount of wood, which is conducive to environmental protection.

Abstract

The invention relates to school supplies, in particular to a pencil. The pencil is composed of a lead holder and a lead. The lead holder can be used repeatedly and comprises a rod and a head. A vertically-communicated lead slot is formed in the center of the rod. A series of transverse separation slots are distributed in the rod at equal intervals, and the transverse separation slots and the lead slot intercross vertically. The pencil has the advantages that consumption of substantial wood materials is avoided, and environment protection is benefited.

Description

Technical field [0001] The invention relates to a school tool—a pencil, in particular to a pencil. Background technique [0002] At present, common pencils are made up of wooden rods and lead cores. The disadvantages are that the wooden rods are disposable and consume a large amount of wood, which is not conducive to environmental protection. Contents of the invention [0003] In order to overcome the above shortcomings of existing pencils, the present invention provides a pencil that can solve the above problems. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A reusable pen barrel, the pen barrel is composed of a shaft and a head, a lead groove runs through the center of the shaft, and a series of equally spaced transverse compartments are distributed on the shaft. The transverse compartments intersect perpendicularly with the lead grooves. [0006] The invention has the beneficial effects of not consuming ...
