Abstract

The utility model relates to a mechanical pencil with a lead refill storage function, which comprises a hollow penholder, wherein a refill protective tube is arranged in the penholder, and a cap is arranged on the refill protective tube. The mechanical pencil is characterized in that: the refill protective tube is formed by two concentric cylinders, and the joint of the two cylinders is closed; a small hole is arranged in the middle of the penholder, the size of the small hole is more than the diameter of a lead refill; a slip sheet is arranged on the small hole, and one end of the slip sheet extends out of the penholder to form a pick; and the diameter of the cylinder which is on the refill protective tube and far from the penpoint is larger than the diameter of the cylinder close to the penpoint, thus forming a refill storage tube. The mechanical pencil has the characteristic that the refill protective tube with the same diameter is set to be a refill storage tube with a larger end, thereby facilitating the storage of lead refills and bringing convenience for use.

Description

Propelling pencil with pencil-lead memory function
Technical field
The utility model relates to a kind of propelling pencil, belongs 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.
The utility model content
The utility model technical problem to be solved 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 utility model is to realize 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 utility model has following positive effect: the retaining core pipe of the utility model 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 the structural representation of the utility model;
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 utility model is done further detailed description.
Fig. 1 is the structural representation of the utility model, 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 the technical scheme of the utility model in any form, and every employing is equal to the protection domain that replacement or the technical scheme that mode obtained of equivalent transformation all drop on the utility model.
