Abstract

The utility model discloses a painting pencil comprising a sleeve, a rotary tube, a bearing tube and a pigment body, wherein a spiral groove is arranged in the sleeve; the rotary tube is arranged in the sleeve in a rotating manner and comprises a driving part and a driven part, and a guide groove is arranged on the driven part; the bearing tube is movably arranged in the rotary tube, more than one positioning pin is arranged on the outer side of the bearing tube, passes through the guide groove and is inserted on the spiral groove; and the pigment body is fixed in the bearing tube. The pigment body can be changed, so that the painting pencil can be utilized for a plurality of times; an operator holds the rotary tube and the sleeve, and can prevent the pigment from staining the hands of the operator; and the rotary tube is rotated, so that the pigment body can be rotated out and still can be used when being not enough long to be held, so and the utilization ratio is improved.

Description

A kind of fine arts pencil

Technical field

The utility model relates to a kind of stationery, relates in particular to a kind of fine arts pencil.

Background technology

In the prior art, fine arts pencil mainly is made up of one deck epidermis and pigment body.Different with the layer of wood of common pencil, said epidermis is thinner, need not bear user's curable grip, is mainly used in to prevent that pigment from sticking on every side on the object.In use, scrape off said epidermis with needing a section.Because said epidermis belongs to disposable product, and complex manufacturing technology, so that the cost of said fine arts pencil is higher.In addition, when said fine arts pencil residue length more in short-term, often have to abandon, and then the environmental pollution that causes owing to lacking the position that grips.Between this, prior art has necessity of further improvement.

The utility model content

The technical problem that the utility model will solve is to provide a kind of fine arts pencil, and this fine arts pencil need not to make epidermis, reduced cost, and when lacking the holding area, still can use, and has improved the utilization rate of pigment.

For solving the problems of the technologies described above, the utility model adopts following technical proposals.

A kind of fine arts pencil is characterized in that comprising: sleeve pipe, swivelling pipe, carrying pipe, pigment body,

Wherein, be provided with helicla flute in the said sleeve pipe; Said swivelling pipe is arranged in the said sleeve pipe rotationally, and said swivelling pipe comprises initiative part and effector, and said effector is provided with gathering sill; Said carrying pipe is arranged in the said swivelling pipe movably, and the outside of said carrying pipe is provided with more than one alignment pin, and said alignment pin passes said gathering sill, and is inserted on the said helicla flute; Said pigment body-fixed is in said carrying pipe.

Adopt the utility model of technique scheme; Said alignment pin passes said gathering sill and inserts said helicla flute; So when said swivelling pipe rotates with respect to said sleeve pipe; Said carrying pipe rotates along the spiral fluted direction with respect to said sleeve pipe, and moves with respect to the direction of swivelling pipe along gathering sill.So, just can regulate the position of said carrying pipe, and then regulate the length of exposing of pigment body.Because helicla flute has self-locking action, promptly receives the time spent of doing of the power of writing at the pigment body, this active force can not cause swivelling pipe to rotate with respect to sleeve pipe, can not cause the length of exposing of pigment body to change yet.

In this fine arts pencil of the utility model, said alignment pin is two, and is arranged on the outside of said carrying pipe symmetrically.

Implement this fine arts pencil of the utility model, have following beneficial effect: said pigment body can be changed, and makes this fine arts pencil repeatedly to utilize; The operator is held on said swivelling pipe and the sleeve pipe, can prevent that pigment from sticking in the operator on hand; Can said pigment body be screwed out through the said swivelling pipe of rotation, when said pigment body length grips inadequately, still can use, improved utilization rate.

Fig. 2 is the explosive view of Fig. 1;

Fig. 3 is the sketch map of a kind of preferred implementation of this fine arts pencil of the utility model, has saved the pigment body among the figure, has mainly showed the structure of said helicla flute and gathering sill;

Fig. 4 is a kind of cutaway view of Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description.

This fine arts pencil referring to figs. 1 through the utility model shown in Figure 4 is characterized in that comprising: sleeve pipe 1, swivelling pipe 2, carrying pipe 3, pigment body 4.

Wherein, be provided with helicla flute 101 in the said sleeve pipe 1; Said swivelling pipe 2 is arranged in the said sleeve pipe 1 rotationally, and said swivelling pipe 2 comprises initiative part 201 and effector 202, and said effector 202 is provided with gathering sill 203; Said carrying pipe 3 is arranged in the said swivelling pipe 2 movably, and the outside of said carrying pipe 3 is provided with more than one alignment pin 301, and said alignment pin 301 passes said gathering sill 203, and inserts said helicla flute 101; Said pigment body 4 is fixed in the said carrying pipe 3.

In this fine arts pencil of the utility model, said alignment pin 301 is two, and is arranged on the outside of said carrying pipe 3 symmetrically.

Claims (2)

1. fine arts pencil is characterized in that comprising: sleeve pipe, swivelling pipe, carrying pipe, pigment body,

Wherein, be provided with helicla flute in the said sleeve pipe; Said swivelling pipe is arranged in the said sleeve pipe rotationally, and said swivelling pipe comprises initiative part and effector, and said effector is provided with gathering sill; Said carrying pipe is arranged in the said swivelling pipe movably, and the outside of said carrying pipe is provided with more than one alignment pin, and said alignment pin passes said gathering sill, and is inserted on the said helicla flute; Said pigment body-fixed is in said carrying pipe.

2. fine arts pencil according to claim 1 is characterized in that, said alignment pin is two, and is arranged on the outside of said carrying pipe symmetrically.
