New description: [New technical field] This creation is about the improved structure of the nipple combined with the eraser, especially the pencil structure with a large amount of eraser combined and complete protection and convenient use. [Prior Art] ^ See the use form of the pencil and the eraser, as shown in the first figure, the pencil 10 and the eraser 20 are independent individuals, and at least one end of the pencil blade is sharpened. The refill 1 〇1 is for writing, and the rubber k rubbing 2 0 is in a block shape to eliminate the writing trace of the pencil 1 ;; the above-mentioned conventional errone pen 1 橡皮 and eraser 2 0 It must be carried separately, and it needs to be taken separately when it is used, which has practical inconvenience. For this reason, the product structure in which the eraser is bonded to one end of the pencil is disclosed, which can directly reverse the pencil due to a writing error and eliminate the writing trace by the eraser at the other end, thus having a practical application. Convenience; however, the above-mentioned tradition and the eraser combined with the wrong pen structure has the following shortcomings in practical application: 1. Since the eraser combined with the wrong combination is barely placed, there is no protection on its periphery. Therefore, the eraser often has a surface which is dirty, worn or even broken, which affects the quality of use of the eraser. 2. Since the eraser is set to the same outer diameter as the pen and the length is short, there is often a shortage of stock, which is not enough for the longer pencils (especially, there are often writing errors). Primary school students or young children writing 5 M322326). In view of the above-mentioned shortcomings in the structure of the eraser product, which is combined with the wrong pen, the creator has researched and improved the shortcomings of these shortcomings, and finally has this creation. [New content] The main purpose of this creation is to provide a pencil-improved structure combined with an eraser. The eraser surface combined with the wrong pen is coated with a coated paper to form a protective layer. 4 X effectively avoids the dirty surface of the eraser. Stain, wear and even break. Another object of the present invention is to provide a pencil-integrated structure that incorporates an eraser whose eraser has a sufficient stock to adequately satisfy the large amount of use. In order to achieve the above objects and effects, the technical means adopted include: a pencil unit having a pen core protruding outwardly at one end for writing, and an outer diameter concavity at the other end portion thereof. An intermediate convex portion; an eraser unit is formed by wrapping a wrapping paper around a periphery of a rubber core, and the covering paper is provided with a tearing line extending in parallel with the rubber core for destroying the wrapping paper One end of the rubber core is gradually exposed, and the eraser unit is provided with an intermediate recess at the other end of the exposed rubber core, so as to fit the middle convex portion of the wrong pen unit to form a joint. As for the detailed structure, application principle, function and effect of this creation, we can get a complete understanding by referring to the following description according to the following figure: M322326 [Embodiment] Please refer to the second i four figure, it can be clearly seen that this The creation mainly includes two parts: a wrong pen unit 1, an eraser unit 2, etc., wherein one end of the writing unit 1 is provided with an outwardly protruding refill 1 4 ' for writing, and the other end is convex. An intermediate convex portion 11 ′ having an outer diameter is provided on the opposite sides of the base portion of the intermediate convex portion 11 respectively, and an axially extending side groove 12 is provided to the other end, and a through shaft is disposed in the side groove 1 2 . The hole 1 3, the rubber v-scraping unit 2 is wound on the periphery of a rubber core 24 by the wrapping paper 25, and the wrapping paper 25 is provided with a tear extending in parallel with the rubber core 24. The wire 2 6 is for destroying the wrapping paper 25 to gradually expose the rubber core 2 to the outside, and the eraser unit 2 is provided with an intermediate recess 2 1 at the other end of the bare rubber core 2 4 Two side protrusions 2 2 corresponding to the side grooves 1 2 of the pencil unit 1 are disposed on the periphery of the opening of the intermediate recess 2 1 , A shaft hole 2 2 1 corresponding to the shaft hole 13 of the pencil unit 1 ′ is respectively disposed on the two side convex portions 2 2 , so that the middle convex portion 1 1 of the pencil unit 1 can extend into the rubber cleaning unit 2 In the middle recessed hole 2 1 , the pencil unit 1 and the eraser unit 2 can be combined and positioned by a positioning pin 23 and a shaft hole 2 2 1 and a shaft hole 13 respectively. The fifth figure is the creation of the present invention. A schematic diagram of the use case, as shown in the figure, it can be seen that the present application can be combined with the other end of the pencil unit 1 in the actual application. If there is a writing error during use, the 2 can be directly transferred to the front. The side 'to wipe the part of the writing error to correct the error. — As can be seen from the above, the creative structure of the pencil combined with the eraser has a lot of eraser and is fully protected and easy to use. M322326 has industrial applicability, novelty and progressiveness. However, the above is only one of the best examples of this creation, and is not intended to limit the scope of the implementation of this creation. Equal changes and modifications in the scope of patents are The scope of this creation patent is covered. [Simple description of the diagram] The first diagram is a schematic diagram of the structure of the pencil and eraser. The second diagram is the exploded view of the creation of the creation. The third diagram is the combined appearance of the creation. The diagram is a schematic diagram of the overall combination of the creation. The fifth diagram is a schematic diagram of the use of the creation.
