| 摘要 |
The present invention relates to construction assemblies or modules. There are attachment members that are connected by pressing an elastic protrusion head through an aperture and threading the protrusion head from one side of the aperture to the other. As the area of the aperture is smaller than area of front projection plane of the protrusion head, threading the protrusion head into the aperture requires the deformation of the protrusion head. After traversing the aperture, the protrusion head returns to its non-deformated shape, and the protrusion neck is settled within the aperture. |
