[0002] In the prior art, there are many structures for connecting pipes through connecting fittings. When connecting pipes, especially the connection between the column and the horizontal tube, generally the connecting piece is fastened to the column with screws first, and then the horizontal tube is screwed together with screws. Tightly installed on the connecting piece to realize the fast connection between the column and the horizontal pipe. This commonly used connecting piece cannot be installed afterward, resulting in complicated installation steps and low installation efficiency. However, there are connecting pieces with post-installation function on the market. During installation, most of the screws are exposed on the outer surface of the pipe, which affects the appearance. On the other hand, it is prone to rust. Over time, it will affect the connection strength and even lead to connection failure.

The invention discloses a fastening connection assembly for a tube provided with a pre-formed hole. The fastening connection assembly comprises a connector and a jackscrew, wherein a clamping pin and a shifting plate are arranged at one end of the connector. When the shifting plate is shifted, the connector moves towards the tube provided with the pre-formed hole, the clamping pin extends into the pre-formed hole, the portion of the connecter located outside the pre-formed hole is in expansion connection with a common tube by screwing the jackscrew and drives the clamping pin to be fastened in the pre-formed hole in an expanding mode. The fastening connection assembly has the advantages of being simple in structure and capable of effectively improving the installation efficiency, the sealing performance and the visual effect.
