Description

STRUCTURE OF PENCIL ASSEMBLY ELONGATED BY COMBINATION

The present invention relates to a pencil assembly that is to extend the length by the coupling, to be described in more detail, there is provided a main bag of the pencil having an annular fixing member, and the connection bag for extending the pencil length having a fixing collar, The present invention relates to a pencil assembly that allows a user to conveniently hold a pencil and achieve environmental protection purposes.

If you use a pencil with a knife, the length of the pencil becomes shorter and shorter when you use the pencil repeatedly. This way, if the remaining pencil is about one third of the total length, it will be difficult to grasp the pencil and discard the pencil. Because resources are so limited today and wood harvesting is likely to destroy forests and human living environments, the waste of such resources must be banned and improved.

The pencil auxiliary rod (refer FIG. 1 and FIG. 2) currently marketed is comprised of the gripping rod 10 and the sleeve 20. As shown in FIG. The holding rod 10 is provided with a flange 11 at a lower portion thereof, and a screw portion and a plurality of clamping members 12 are provided at the flange. The sleeve 20 is provided with a through hole 21 extending therethrough. The gripping rod 10 is fixed to the sleeve 20 by inserting and gripping the gripping rod 10 into the through hole 21. Connect. If the length of the pencil 30 is inappropriate for the user to grip, insert the pencil in the center of the clamping member 12 of the gripping rod 10, and then screw and tighten the sleeve 20 to the clamping member 12 The pencil 30 is fixed. In this way, the pencil 30 is fixedly connected to the gripping rod 10, thereby solving the above-described problem of gripping difficulty, so that the main bag of the pencil can be continuously used.

Although it is possible to continue using the pencil by such an auxiliary rod, this auxiliary rod has the following drawbacks.

1. The production cost of auxiliary rod is high. In addition, the clamping member provided on the gripping rod is easily broken and deformed, making it unusable.

2. Insert the pencil into the gripping rod and screw it into the sleeve to engage the pencil and the gripping rod, which is often impossible for the user to detach the pencil from the gripping rod by applying excessively high force to force the pencil into the gripping rod. This is not easy.

3. When connecting the pencil to the gripping rod, the length of the rear end of the pencil must be quite long for such a connection, or it may remain unstable and shake. Thus, although pencils can be used to some length, they cannot be used up completely.

Based on the above-mentioned drawbacks of the above-described conventional auxiliary rods used to extend the length of the pencil, the inventors of the present invention have the simplest and simplest way to reduce the production cost of the auxiliary rods and increase the ease of assembly and use of the pencil. Consideration was given to extending the length of the pencil in a certain way. Accordingly, the inventor of the present invention provides the pencil assembly of the present invention based on a long time professional experience in the research, design and manufacture of similar products, and with a great deal of effort while undergoing several tests and inspections. Was done. According to the present invention, waste of resources and defects of the conventional auxiliary rod can be solved.

The main object of the present invention is to provide a pencil assembly that is simple and convenient to assemble. In this connection, an annular fixing member is provided on the main bag of the pencil, and a fixing collar is provided on the connecting bag of the pencil. The length of the pencil assembly can be extended by connecting the annular fixing member of the main bag of the pencil and the fixing collar of the connecting bag of the pencil. Accordingly, it is possible not only to solve the defects of the conventional auxiliary rod, but also to achieve the purpose of environmental protection and production cost saving.

The invention will become clear by reading the detailed description of the preferred embodiment with reference to the drawings.

3 to 5, the subject innovation is the main bag 40 and the connecting bag 50 of the pencil as a main configuration. The main bag 40 is provided with an annular fixing member 41, and the annular member 41 is also provided with a fastening stub 42 having a thread formed on its outer surface. The connecting bag 50 is provided with a fixing collar 51 which cooperates with the annular fixing member 41. In the center of the fixing collar 51 is provided a fastening hole 52 in which the fastening stub 42 is screwed. The fastening hole 52 has a threaded inner surface. The fastening stub 42 and the fastening hole 52 are different from those described above, that is, the fastening stub 42 is provided in the fixing collar 51 while the fastening hole 52 is provided in the annular fastening member 41. It may be provided in the form.

If the length of the main bag 40 is repeatedly cut and used to reduce the uncomfortable grip, the fastening stub 42 provided at the rear end of the main bag 40 is screwed into the fastening hole 52 of the connecting bag 50. Combination can be fixed, thereby extending the length of the connecting bag 50, it is possible to conveniently hold the pencil and continue to use until the bag 40 is completely used.

The connecting bag 50 may be used in cooperation with the main bag 40 so that after the full use of the main bag 40, the connecting bag 50 may be shaved. Fastening of the connection bag 50 and the main bag 40 of the present invention is fast and convenient, can greatly reduce the waste of resources. The annular fastening member 41 and the fastening collar 51 may be integrally formed with the main bag 40 and the connecting bag 50, that is, the fastening stub (protruding directly to one end of the main bag 40) 42 is provided, and a fastening hole 52 connectable with the fastening stub 42 is provided at one end of the connecting bag 50 (see FIG. 5).
