Description

A kind of clip pencil

Technical field

The utility model relates to a kind of pencil, particularly a kind of clip pencil.

Background technology

Use traditional pencil, when nib should sharpen a pencil when too weak point can't be write.But know that pencil all makes with timber, sharpening a pencil so again and again, annual timber quantity of being wasted not is a decimal fractions, in order to save timber, people have made propelling pencil, the complex structure of this pen, and the change-fountain pen core is very inconvenient, easily pen core is fractureed, the more wooden pencil of the price of this propelling pencil is expensive and very not durable from structure.

The utility model content

The purpose of this utility model just is to provide a kind of simple in structure, change-fountain pen core the convenient and clip pencil of frangibility pen core not.

To achieve these goals, the technical solution adopted in the utility model is such: clip pencil of the present utility model, comprise penholder and pen core, described penholder is a clip structure, two contact-making surfaces at the clip chuck are respectively equipped with parallel with it arc groove, and the cavity that two arc grooves form and the thickness of pen core are complementary.

As preferably, described penholder integral body is cylinder or positive polygon prism.

As preferably, described penholder length is 10～15cm, and the ratio of clamp holder and chuck is 1: 2.

Compared with prior art, advantage of the present utility model is: this clip pencil is simple in structure, easy to use, it reaches the purpose that need not to sharpen a pencil and but equally can use smoothly by the penholder design of clamp type, pen core is put into the arc groove of penholder chuck, after the use, pen core is pulled out any just can continue to use, you only need the replacing pen core at every turn and needn't ream penholder, have saved a large amount of timber.

Description of drawings

Fig. 1 is a front view of the present utility model;

Fig. 2 is the stereogram of Fig. 1 chuck.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 1,2, clip pencil of the present utility model, comprise penholder 1 and pen core 2, described penholder 1 is a clip structure, be respectively equipped with the cavity that parallel with it arc groove 3, two arc grooves 3 form at two contact-making surfaces of clip chuck and be complementary with the thickness of pen core 2, described penholder 1 integral body is cylinder or polygon prism just, described penholder 1 length is 10～15cm, and the ratio of clamp holder and chuck is 1: 2.

This clip pencil is simple in structure, easy to use, its penholder 1 is a clip structure, during use, only need pen core 2 is clipped in arc groove 3 interior can the uses of clip, the cavity that two arc grooves 3 form and the thickness of pen core 2 are complementary, so in use pen core 2 can not drop out, the ratio of penholder 1 clamp holder and chuck is 1: 2, you only need very little power just can change pen core 2, in the time of can't writing, pen core is pulled out any just can continue to use, you only need the replacing pen core at every turn and needn't ream penholder, have saved a large amount of timber.
