Abstract

The utility model discloses a convenient pencil with writing-core feeding mechanism, which has the advantages that pencil leads with different specifications can be used on one pencil holder; the pencil leads are not easy to be broken off; the blunt pencil nibs can be ground anytime thus satisfying nibs can be kept; the structure is simple; the use is convenient, etc. The utility model comprises a pencil holder (4), a pencil lead tube (5) for containing the pencil leads, a hollow conical pencil lead protecting nib (7) which is reelingly sheathed on the lower end of the pencil lead tube (5), and a grinding wheel sleeve cover (1) with a conical grinding hole, which is sheathed on the top of the pencil lead tube (5), etc.

Description

Comvenient pencil with writing-core feeding mechanism

The utility model belongs to writing implement, especially a kind of portable propelling pencil that uses the different size pen core on same penholder.

Existing propelling pencil can only use a kind of pen core of specification at the one-pen bar, and thin pen core frangibility, and the thick easy chap of pen core stroke is not easy to use.

It is a kind of simple in structure, easy to use that the purpose of this utility model is to provide, and can use the pen core of different size on same penholder, and pen core is frangibility not, can grind at any time and draw thick nib, makes it to keep the portable propelling pencil of good nib.

Portable propelling pencil of the present utility model adopts the body of rod and the pen core tube of existing propelling pencil, and the lower end of penholder fixedly rotation set hollow taper and protects the core mouth, and the upper end buckle closure of penholder the emery wheel upper shield of band taper grinding hole.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is a structural representation of the present utility model

Portable propelling pencil of the present utility model by hollow penholder (4), nib (3), accommodate pen core pen core tube (5), protect core mouth (7) and emery wheel upper shield formations such as (1).Shell is a metal material, and inner chamber is inlayed the hollow taper that elastomeric material makes and protected core mouth (7) rotation set on the screw rod of pen core tube (5) lower end, makes penholder (4), pen core tube (5) and protect core mouth (7) fixing as a whole.Awl point core mouth (7) the inner chamber middle part of protecting down is provided with pen core rest pad (8), prevents that pen core (6) from fractureing in inside when writing.The upper end outlet of pen core tube (5) embeds rubber bar (2), there is emery wheel upper shield (1) buckle closure of taper grinding out at the center on pen core tube (5), take off emery wheel upper shield (1), a stroke thick pencil stub is stretched in the taper grinding hole rotate several times, just can obtain satisfied nib.

When using portable propelling pencil of the present utility model, the pen core of can be simultaneously putting into different size in the pen core tube (5), constantly press the emery wheel upper shield (1) that cover is buckled in pen core tube (5) upper end, pencil-lead will stretch out from pen core tube (5) lower end through protecting core mouth (7).Pen core (6) can reduce hron spacing protecting the protecting under core rest pad (8) clamping of core mouth (7) inner chamber, is difficult for when making it to write fractureing in inside.Because protecting core mouth (7) inner chamber is elastomeric material,, also can hold tight thinner pen core so both can pass through thick pen core.During written chap in using, desirable lower grinding wheel upper shield (1) stretches into nib that turn just can make written sharpening several times in its taper grinding hole.

Portable propelling pencil of the present utility model has kept the characteristics of existing propelling pencil, and can use at same penholder the pen core of different size, and pen core is frangibility not, can at any time grind the nib of chap, has the advantages such as simple in structure, easy to use.

Claims

1, a kind of portable propelling pencil that on same penholder, uses the different size pen core, adopt the existing propelling pencil body of rod and pen core tube, the lower end that it is characterized in that pen core tube (5) fixedly rotation set shell be metal material, inner chamber is inlayed elastomeric material and is made, the inner chamber middle part is provided with the pen core rest pad (8) that anti-pen core fractures, and awl point hollow taper down protects core mouth (7); There is the taper grinding hole at the buckle closure center of, upper end of pen core tube (7), is used to grind the emery wheel upper shield (1) of nib.
