TECHNICAL FIELD
[0001] The utility model relates to drawing charcoal pen technical field, more specifically, the utility model relates to a three -segment type rotation connection's free -cutting charcoal pen. BACKGROUND
[0002] In art painting, since the charcoal pen on the market is mostly wooden, it is difficult to use a charcoal pen completely, and it is easy to break, which causes waste of wooden resources and cannot be recycled. Secondly, most charcoal pens are wrapped with wood and need to be cut by oneself when used, which wastes a lot of time. Even if there is a manual pencil sharpener and an electric pencil sharpener, it is easy to jam the lead and needs to spend extra money. Finally, most charcoal pens are limited to one material, and in art painting, soft, medium and hard materials need to be replaced, which is not very convenient. Some free-cutting charcoal pens on the market only limit the free-cutting of the outer wrapping of wooden products and cannot avoid the grinding of charcoal lead. SUMMARY

[0007] As a preferred technical scheme of the utility model, the bite petal one, the bite petal two and the bite petal three are provided with five petal bite petals.
[0008] As a preferred technical scheme of the utility model, the pen barrel one, the pen barrel two and the pen barrel three are of the same length.
[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model integrates three different types of pencil leads into one unit by setting three pencil barrels to achieve multiple uses; it can solve the problem that automatic charcoal pencils with only one material cannot meet the needs of drawing and that multiple types need to be purchased; the overall structure is simple, the design is reasonable, and it is convenient to use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] like Figures 1 to 4 As shown, this utility model provides a three-section rotating connection no-sharpening charcoal pencil, including: a pencil cap 1, a tail cap 5, and a pencil barrel assembly. The pencil barrel assembly consists of a first pencil barrel 2, a second pencil barrel 3, and a third pencil barrel 4. One end of each of the first pencil barrel 2, the second pencil barrel 3, and the third pencil barrel 4 is respectively provided with an engagement flap 1 6, an engagement flap 2 7, and an engagement flap 3 8, in which a pencil lead is installed. The first pencil barrel 2 is connected to the pencil cap 1 via a threaded structure, and the end of the third pencil barrel 4 is provided with a retaining ring 12 that engages with the tail cap 5. The three pencil barrels, the first pencil barrel 2, the second pencil barrel 3, and the third pencil barrel 4, are connected at their ends and interlocked.
[0017] The end of the pen barrel one 2, the pen barrel two 3 and the pen barrel three 4 is respectively provided with the occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 to install the pen core, the pen core in different pen barrels is set to be different, so that different pen barrels can be used according to the use requirement, thereby meeting the use requirement. The pen barrel one 2, the pen barrel two 3 and the pen barrel three 4 are connected with each other, the end of the pen barrel two 3 and the pen barrel three 4 is respectively embedded into the inside of the pen barrel connected therewith, in addition, the pen barrel one 2 is connected with the pen cover 1 through the thread structure, the end of the pen barrel three 4 is provided with the snap ring 12 to be clamped with the tail cover 5, thereby forming the complete free-shaving carbon pen. The main connection mode is to connect the three parts through the thread connection, so as to realize the stability and not easy to loosen, the assembled carbon pen product is integrated with the beauty and the practicability, thereby providing the convenience for the painter.
[0018] The occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 are provided with the pen tip one 9, the pen tip two 10 and the pen tip three 11 outside, the pen tip one 9, the pen tip two 10 and the pen tip three 11 are all set to be the conical structure and are respectively installed on the occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 through the thread structure. The end of the pen tip one 9, the pen tip two 10 and the pen tip three 11 is provided with the through hole, the pen core in the occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 is passed out from the through hole.
[0019] The pen tip one 9, the pen tip two 10 and the pen tip three 11 are respectively installed on the occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 through the thread structure, after the pen tip is screwed, the occlusion petal can be squeezed inward, thereby occluding the pen core, fixing the pen core to avoid the up and down sliding, thereby affecting the use. The pen core can be passed out from the through hole of the pen tip, thereby not affecting the normal use. The occlusion petal on the inside can be loosened by unscrewing the pen tip, thereby loosening the pen core, facilitating the adjustment of the pen core or taking out the pen core to replace it.
[0020] The occlusion petal one 6, the occlusion petal two 7 and the occlusion petal three 8 are set to be the occlusion petal with five petals, the pen barrel one 2, the pen barrel two 3 and the pen barrel three 4 are the same in length.
[0021] The occlusion petal with five petals can wrap the pen core in all directions, the occlusion petal has good elastic deformation capacity and can be repeatedly used. The position of the pen barrel one 2 and the pen barrel two 3 can be flexibly adjusted to meet the use requirement, the three can be used together or independently.
