The top of the lower riveting nut structure 1 is in contact with the bottom of the plate, and the bottom of the upper riveting nut structure 2 is in contact with the top of the plate. A fixing bolt is disposed inside the upper riveting nut structure 2.

[0030] Further, for the lower riveting nut structure 1, it includes a first fitting plate 101. A first fitting strip 102 is disposed on the top of the first fitting plate 101. The number of the first fitting strips 102 is set to be multiple, and the multiple first fitting strips 102 are annularly arrayed on the top of the first fitting plate 101. An installation tube 103 is disposed on the top of the first fitting plate 101. A first thread 104 is provided at the top inner wall of the installation tube 103, and 105 is provided at the bottom inner wall of the installation tube 103.
