This propelling pencil and box-packed pen core systems selling, 30-50 root pen core generally is housed in order to replace in the Pencil lead box, because of its structure small and exquisite easy to carry, but also can cause when the propelling pencil pen core need be changed sometimes, can not find Pencil lead box and can't change core, influence its use, make troubles for study, work.

The utility model content

For the Pencil lead box that solves existing propelling pencil is lost easily, can't change when causing to change core, the defective of influence study, work, the utility model provides a kind of core to connect the core propelling pencil, it is stored in propelling pencil inside with pen core, realize that Pencil lead box, propelling pencil are integrated, efficiently solve the defective of prior art.

In order to realize that the technical scheme that the utility model purpose is adopted is: a kind of core connects the core propelling pencil, it is characterized in that: it by penholder 5, clamp 4, beam ring 2, reservoir shaft button 1, go out core apparatus and constitute.

Described penholder 5, reservoir shaft button 1, go out core apparatus and adopt traditional automatic pencil structure;

The described primary structure that goes out core apparatus has reservoir shaft 6, spring etc.;

Described beam ring 2 is provided with beam ring reservoir shaft hole 7, beam ring reservoir hole 8, and beam ring reservoir shaft hole 7 diameters are suitable with reservoir shaft 6, and beam ring reservoir hole 6 diameters are suitable with the pen core diameter;

Described clamp 4 is provided with clamp reservoir shaft hole 9, clamp reservoir hole 10, clamp reservoir shaft hole 9 diameters are suitable with reservoir shaft 6, reservoir shaft 6 is passed beam ring reservoir shaft hole 7 and is connected to reservoir shaft button 1 with clamp reservoir shaft hole 9, clamp reservoir hole 10 diameters are suitable with the pen core diameter, clamp 4 parts are fixing with penholder 5, another part forms pen core interlayer 11, in order to store pen core.

The beneficial effects of the utility model are: pen core is stored in propelling pencil inside, make full use of the space between penholder and the reservoir shaft, realize that Pencil lead box, propelling pencil are integrated, effectively solution is lost because of Pencil lead box and can't in time be changed the inconvenience that core brings, simple in structure, easy to operate, be applicable to various study, office space.
