[Prior art]

 When articles are connected in different horizontal and vertical directions, the volume after connection becomes considerably large, and a very large problem arises when transporting large-volume articles. If the volume is large during transportation, it is quite inconvenient to transport even if the weight is relatively light.If the product is disassembled, it can return to the volume before assembly, it can be easily transported, and it can be assembled again after transporting it to the destination, The burden on transport workers can be reduced. However, when disassembling the goods, it is necessary to check if the goods cannot be disassembled by the fixing method adopted when combining the goods. If they cannot be disassembled, they must be transported in the entire volume.

[0003] In general, the connection of articles is mostly fixed by nailing, but once the articles are joined and fixed by nailing, they cannot be disassembled, and if they are disassembled, holes remain in the articles. A gap is generated, and the article becomes wobble and unstable during use. However, nailing at a new location, avoiding the original hole, left many holes in the article, considerably deteriorating the appearance of the article.

[0004] Furthermore, when the article is fixed with an adhesive, the adhesive is applied to the bonding surface before the article is bonded, and the article is further bonded after the adhesive has dried, and usually a considerable amount of time is spent. However, once the article was bonded, it could not be disassembled, so the disassembled surface of the article had to be destroyed, resulting in damage to the article. Therefore, the adhesive type article can be used only once and has no effect of multiple use.

[0005] Further, some articles are combined and fixed with screw parts, and the screw parts have a decomposable effect, and can be fixed repeatedly. However, the combination of screw parts and screw holes was tight in the first time, but loosened in the second and subsequent times, making it impossible to secure the goods tightly. If it is fixed at a different position, the screw hole left at the original position will affect the appearance, and screwing at the new position tends to cause displacement or distortion, and the article cannot be fixed firmly.

[0006] There are currently many combinatorial articles on the market, all of which are assembled by consumers themselves, and most of the assembled parts are fixed with screw parts or joined with wood screws. However, such an assembling method is difficult to disassemble once the articles are assembled, and it is difficult to transport the whole large-volume articles when carrying and moving is necessary, which is considerably inconvenient. If the screw parts or wood screws were removed to forcefully disassemble the article, the phenomenon of loosening when attaching the screw parts or wood screws again when newly reassembling, and becoming less robust occurred, shortening the life of the assembled article. .

[0007] The above-described method of combining a number of articles is required to be improved because the drawbacks of the use of the coupling tool make it difficult to disassemble, assemble and use the articles, and cause many problems and inconveniences during transportation.

[0008]
