<p>The present invention relates to a joining assembly to couple a plurality of parts to each other capable of easily separating a pair of joining assemblies with a same structure from each other; manufacturing the joining assemblies at a low height; and controlling an angle by rotating the coupled joining assemblies without disassembly while maintaining a constant angle as two parts are not arbitrarily rotated from each other in a state where the pair of joining assemblies is coupled to each other. The joining assembly comprises: a housing part having an internal installation space and a plastic deformation coupling part protruding from a center of the installation space while a diameter of an end is expanded by compression; and coupling blocks having a penetration hole formed on the center and a plurality of coupling pieces circumferentially formed on the penetration hole. The plurality of coupling pieces is formed on the penetration hole at the same interval. The coupling blocks are inserted in the installation space to be rotated. Each coupling piece comprises: a positioning coupling piece having at least a part protruding outside of the installation space, and positioned in a space between the coupling piece of the other coupling block when the two coupling blocks close to each other are coupled to each other; and a cantilever type elastic coupling piece protruding from one side of the positioning coupling piece in the same direction as the positioning coupling piece. A holding protrusion heading outside of the installation space protrudes from one side of the end of the elastic coupling piece such that a pair of joining assemblies with the same structure can easily be attached and detached from each other by a fitting method. The coupling blocks and the coupling pieces are coupled to easily be assembled while being naturally rotated in a coupling process of the joining assemblies.</p> |
