Abstract
The invention relates to a mechanical pencil with a pencil refill storing function. The mechanical pencil comprises a hollow pencil holder, wherein a refill protecting tube is arranged in the pencil holder, and is provided with a cover body. The mechanical pencil is characterized in that: the refill protecting tube consists of two concentric cylinders; the joint of the two cylinders is enclosed; the middle part of the refill protecting tube is provided with a small hole; the diameter of the small hole is greater than the diameter of a pencil refill; the small hole is provided with a slide sheet; one end of the slide sheet extends out of the pencil holder, so that a pushing sheet is formed; and the diameter of the cylinder on the refill protecting tube which is far away from a pencil point is greater than that of the cylinder which is close to the pencil point, so that a refill storing tube is formed. In the invention, refill protecting tubes of the same diameter are designed into refill storing tubes which are larger at one end, so that pencil refills are convenient to store; and the mechanical pencil is convenient to use.
Description
Technical field
The present invention relates to a kind of propelling pencil, belong to stationery.
Background technology
General propelling pencil, retaining core pipe are the cylindrical of one, only can store several pencil-leads, also need special pencil lead holder, and the process of additional pencil-lead are cumbersome.
Summary of the invention
Technical problem to be solved by this invention provides a kind of propelling pencil, can store more pencil-lead, and is easy to use.
For solving the problems of the technologies described above, the present invention realizes like this
Propelling pencil with pencil-lead memory function comprises the hollow penholder, is provided with retaining core pipe in the penholder; Retaining core pipe is provided with lid, it is characterized in that retaining core pipe is made up of two concentric columns, two cylinder junction sealings; The middle part has aperture, and the size of aperture is greater than the diameter of a pen core;
And aperture is provided with slide plate, and an end of slide plate extends penholder and forms plectrum;
Body diameter away from nib on the retaining core pipe forms core storage tube greater than the body diameter near nib;
The present invention has following positive effect: the retaining core pipe of the present invention's same diameter is set to the bigger core storage tube of an end, is convenient to deposit pencil-lead, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein: 1-penholder, 2-retaining core pipe, 3-core storage tube, 4-plectrum, 5-lid.
The specific embodiment
Below in conjunction with the specific embodiment the present invention is done further detailed description.
Fig. 1 is a structural representation of the present invention, and with reference to shown in Figure 1, the propelling pencil with pencil-lead memory function comprises hollow penholder 1, is provided with retaining core pipe 2 in the penholder 1, and retaining core pipe 2 is provided with lid 5.Retaining core pipe 2 is made up of two concentric columns, two cylinder junction sealings, and the middle part has aperture, and the size of aperture is slightly larger than the diameter of a pen core.And aperture is provided with slide plate, and slide plate is connected with spring, and an end of slide plate extends penholder and forms plectrum 4, stirs plectrum 4, slide plate sidesway then, and aperture is opened, and pen core can drop on the retaining core pipe bottom through this aperture, loosens plectrum 4, and aperture is closed in then slide plate travelling backwards.
Wherein, form core storage tube 3 away from the body diameter of nib greater than the body diameter near nib, the quantity of the pencil-lead that holds is greater than core storage tube itself.
The above-mentioned specific embodiment does not limit technical scheme of the present invention in any form, and the technical scheme that mode obtained that every employing is equal to replacement or equivalent transformation all drops on protection scope of the present invention.
