[Technical field to which the invention belongs]

 The present invention relates to a kind of articulated extension type pencil structure, in particular, one fixed ring is provided on the main pencil shaft, and one stopper ring is provided on the combined pencil shaft, and the fixed ring and the stopper ring are combined. The present invention relates to an articulated extended pencil structure that can extend the length of a pencil and achieve the user's grip and resource conservation.

[0002]

[Prior art]

 If the pencil is sharpened to about one-third its length, it is often thrown away because it is difficult to grip. However, given the limited resources and the fact that logging would lead to the destruction of forest resources and the destruction of the environment, it was necessary to take measures against such resource waste.

[0003] A pencil auxiliary rod currently sold in the market (see Figs. 1 and 2) is composed of one gripping rod 10 and a cylindrical body 20, and one convex ring 11 is provided below the gripping rod 10. A screw thread and a small number of holding pieces 12 are provided below the convex ring 11. The inside of the cylindrical body 20 is formed with a through-hole 21 that penetrates, and the gripping rod 10 is placed in the through-hole 21 and screwed and fixed to each other. When the length of the pencil 30 is short and it becomes difficult for the user to grip, the pencil 30 is inserted into the holding piece 12 of the gripping rod 10 and the cylinder 20 is laid from below to above. By turning and tightening, the pencil 30 is held and fixed by the holding pieces 12. In this way, the pencil 30 is easily gripped by the gripping bar 10, and the remaining lead brush 30 can be used continuously.

[0004] The above-mentioned known auxiliary bar achieves the purpose of enabling the continuous use of the pencil, but has the following disadvantages in use. 1. The production cost of the auxiliary rod is high. In addition, the holding piece provided at the lower part of the gripping rod was easily inadvertently torn and deformed when the pencil was inserted, making it unusable. 2. The method of inserting the pencil into the gripping rod and then tightening it with the cylinder is that if the user uses too much force when using it, the pencil will easily retract into the gripping rod and will not be able to be removed. , A situation that made it difficult to take out occurred. 3. When combining the pencil and the gripping rod, the rear end of the pencil must be held for a considerable length, otherwise the instability of the grip causes the pencil to wobble, so that a relatively large number of pencils can be used. , Its use was limited.

[0005] Therefore, there has been a need for a method which can extend the usable length of the pencil in a simpler and more reliable manner, not only saves the production cost of the auxiliary rod but also is convenient for combination and use.

[0006]

[Problems to be solved by the invention]

 The main purpose of the present invention is to provide a kind of a simple structure, an articulated extension type brush structure that is easy to assemble, that is, one fixed ring is provided on the main pencil shaft, and a combined pencil is provided. To achieve the purpose of providing one fitting ring on the shaft, connecting the fixed ring and the fitting ring to extend the pencil so that it can be used continuously, and to achieve the purpose of securing resources and reducing manufacturing costs. It is in.

The articulated and extended pencil structure according to claim 1 or 3. The invention according to claim 6 is characterized in that the main pencil shaft is connectable to one auxiliary rod, and the auxiliary rod is provided with a screw hole capable of screwing with a screw post of the main pencil shaft. In this case, the connecting extension type pencil structure according to claim 4 is used.

[0008]

[Embodiment of the invention]

 As shown in FIGS. 3 to 5, in the present invention, one main pencil shaft 40 and a combined pencil shaft 50 are combined with each other, and a fixing ring 41 is provided at the rear end of the main pencil shaft 40. A screw connection column 42 having a male screw is extended from a center portion of the ring 41, and one engagement ring 51 is provided at a corresponding end of the coupling pencil shaft 50. A screw contact hole 52 that can be screwed with the column 42 is provided, and a female screw is formed on the inner wall of the screw contact hole 52. Alternatively, the screw connection column 42 may be provided on the fitting ring 51, and the screw connection hole 52 may be provided on the fixed ring 41.

When the main pencil shaft 40 becomes shorter due to continuous use and becomes difficult to grip, by screwing the screw connection column 42 provided at the rear end thereof into the screw connection hole 52 of the combined pencil shaft 50, The length of the combined pencil shaft 50 can be used to increase the ease of gripping by the user, so that the main pencil shaft 40 can be used continuously and the purpose of using the pencil to the end can be achieved. .

The combined pencil shaft 50 can be used in combination with some of the main pencil shafts 40, and the combined pencil shaft 50 can be used after all the main pencil shafts 40 have been used. The interconnecting structure of the main pencil shaft 40 and the connecting pencil shaft 50 of the present invention can be easily and quickly connected, is convenient to use, and can greatly reduce the waste of resources. The fixed ring 41 and the fitting ring 51 are formed integrally with the main pencil shaft 40 and the combined pencil shaft 50, respectively. That is, a screw contact column 42 is directly formed at one end of the main pencil shaft 40, and a screw contact hole 52 that can be directly connected to the screw contact column 42 is formed at one end of the combined pencil shaft 50 (see FIG. 5). .

Further, according to the embodiment shown in FIGS. 6 and 7, there is provided an auxiliary rod 60 which is repeatedly used in combination with the main pencil shaft 40, and the auxiliary rod 60 is formed of plastic or wood. When the screw shaft 61 is formed on the upper part and the main pencil shaft 40 becomes short and it becomes difficult to grip, it is screwed into the screw hole 43 provided in the main pencil shaft 40 and connected. The pencil shaft 40 can be used continuously. In the embodiment shown in FIG. 8, a screw contact column 42 is directly provided at one end of the main pencil shaft 40, and a screw contact hole 44 is formed at the other end of the main pencil shaft 40. The object is achieved that the main pencil shafts are connected to each other so that they can be used continuously without interruption. Thus, the pencil structure is practical, simple in construction and useful for environmental protection.
