Abstract

The utility model relates to an automatic pencil for drawing, comprising a button (1), a connecting piece (2), a pp (Polypropylene) pipe (3), a decorating ring (4), a pen holder (5), a spring (6), a bloom (7), a copper ring (8), a pen point (9) and a pen core (10), wherein the pen point (9) is in a cone shape, and the inner side of the pen point (9) is provided with a stop block; the copper ring (8) is positioned on the stop block and at the bottom of the outer ring of the bloom (7); a spring (6) is sleeved outside the bloom (7); the pp pipe (3) is positioned above the spring (6); the pen core (10) is positioned in the bloom (7) and is fixed by the pen point (9); the pen point (9) is connected with the pen holder (5) through screw threads; the button (1) is connected with the pen holder (5) through the connecting piece (2); and a connection gap between the connecting piece (2) and the pen holder (5) are provided with the decorating ring (4). The utility model can solve the problem that the length of the pen core is difficult to control in the prior art.

Description

A kind of drawing propelling pencil

Technical field

The utility model belongs to the propelling pencil field, particularly relates to a kind of drawing propelling pencil.

Background technology

Existing drawing propelling pencil, using method are given the application of force F of blooming as shown in Figure 1, and the front end of blooming unclamps, the pen core free-falling.But limited owing to bloom to the frictional force of pen core, be not easy to control the position that pen core drops, do not reach desirable effect.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of drawing propelling pencil, to solve the uppity problem of pen core length in the prior art.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of drawing propelling pencil is provided, comprise button, connector, pp pipe, case ring, penholder, spring, bloom, copper band, nib and pen core, described nib is a cone shape, the inboard is provided with a circle block, the bottom, outer ring that described copper band is positioned on the block, blooms, also be with spring outside blooming, described pp pipe is positioned at the spring top.

Described pen core is arranged in blooms, fix by nib, the nib with penholder by being threaded.

Described button is connected with penholder by connector, and connector has case ring with being connected of penholder on the space.

According to different needs, pen core has designed 3 styles, 2.0mm lead for retractable pencil, 2.5mm lead for retractable pencil, 4.0mm lead for retractable pencil:

1: the portrayal in when drawing to details requires preferably to be controlled at about 2.0mm to the thickness of pencil.2.0mm pen core can guarantee certain toughness, thereby does not rupture when drawing.

2:2.5mm be a specification between 2.0mm and 4.0mm, 2.5mm mainly solves and both can use the side cutting edge of a knife or a sword also can portray some details in drawing, kills two birds with one stone.And the toughness of 2.5mm can be better, uses safer.

3: when painting with 4.0mm, biggest advantage is the use of side cutting edge of a knife or a sword, can very random drawing on picture with the pencil-lead drawing of 4.0mm specification.Be easy to spread out big effect, get instant result.Be applicable to literary sketch, sketch etc.And this size of 4.0mm is bigger, and more proper and comfortable with holding, feel is very strong.

Beneficial effect

The utility model has been realized the automatic control of pen core length, the convenient use; And according to different instructions for use pen cores a series of thickness specification is arranged, satisfy different personages' needs.

Description of drawings

Fig. 1 is the automatic drawing pencil of prior art.

Fig. 2 is a structure chart of the present utility model.

Fig. 3 is user mode figure of the present utility model.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

As shown in Figure 2, a kind of drawing propelling pencil, comprise button 1, connector 2, pp pipe 3, case ring 4, penholder 5, spring 6, bloom 7, copper band 8, nib 9 and pen core 10, described written 9 is cone shape, the inboard is provided with a circle block, described copper band 8 is positioned on the block, 7 the bottom, outer ring of blooming, the 7 outer springs 6 that also are with of blooming, and described pp pipe 3 is positioned at spring 6 tops.

Described pen core 10 is arranged in blooms 7, fixing by nib 9, and nib 9 and penholder 5 are by being threaded.

Described button 1 is connected with penholder 5 by connector 2, and connector 2 has case ring 4 with being connected of penholder 5 on the space.

Implementation process:

1. the hand application of force is given button, and button drives pp pipe 3 and moves, pp pipe 3 drive bloom 7, copper band 8, pen core 10 move.When copper band 8 moves 1mm.The block of nib 9 stops moving of copper band 8.Pen core 10 produces the 1mm displacement.

2. this moment, if continue to force in button 1, bloom 7, pp pipe 3 continues to move, but pen core 10 can not move again, because copper band 87 has unclamped with blooming, can not drive pen core 10 and continue to move.

3. after openhanded the opening, because the elastic force effect of spring 6 makes pen recover reset condition again.

4. press 5-6 time back and forth, can obtain the lead for retractable pencil length of oneself wanting.

Claims

1. drawing propelling pencil, comprise button (1), connector (2), pp pipe (3), case ring (4), penholder (5), spring (6), bloom (7), copper band (8), nib (9) and pen core (10), it is characterized in that: described nib (9) is cone shape, the inboard is provided with a circle block, described copper band (8) is positioned on the block, bottom, the outer ring of bloom (7), (7) the outer spring (6) that also is with of blooming, described pp pipe (3) is positioned at spring (6) top.

2. a kind of drawing propelling pencil according to claim 1 is characterized in that: described pen core (10) is arranged in bloom (7), and is fixing by nib (9), and nib (9) and penholder (5) are by being threaded.
