[0016] As shown in the accompanying drawings, a connecting component includes a cuboid 1, which is a cuboid cavity with a top surface 13 and no bottom surface, and a plurality of ribs 12 are fixedly arranged in the cuboid cavity. A central hole 10 is opened in the center of the cuboid, and a thread may or may not be arranged in the central hole. The central hole is connected to the four walls of the cuboid cavity by ribs 12.

[0017] The four corners of the rectangular cavity are integrally provided with the same edges and corners, and the edges and corners are formed by dividing a right trihedral angle into three identical triangular pyramids 4. In this embodiment, the triangular pyramid is a right-angled triangular pyramid, and the right-angled surface A of the triangular pyramid is located on the side where the long side 2 of the rectangular parallelepiped is located, the right-angled surface C of the triangular pyramid 4 is flush with the top surface, and the right-angled surface B is flush with the side 14 where the short side of the rectangular parallelepiped is located.

In this embodiment, an arc transition 15 is used; the vertices of the triangular pyramids at the four corners of the rectangular parallelepiped 1 are connected to form a square, and the three The triangular pyramids on the connecting members are spliced ​​together to form a right trihedral angle. The difference between the long side and the short side of the rectangular parallelepiped is equal to the height of the straight triangular pyramid.
