[0023] Among them, the first composite pipe 1 is provided with a plug-in groove for plugging in the plug-in tube 401 at one end close to the first connecting plate 3. The setting of the plug-in tube 401 and the plug-in groove facilitates the guided connection between the first composite pipe 1 and the second composite pipe 2. The plug-in groove is provided with a fixing groove 302 corresponding to the fixing block 403 one by one. The fixing block 403 on the plug-in tube 401 cooperates with the fixing groove 302 in the plug-in groove, thereby improving the stability of the connection between the first composite pipe 1 and the second composite pipe 2.

[0024] The second composite tube 2 is provided with a second connecting plate 4 at one end close to the first composite tube 1, and a plug-in tube 401 is coaxially extended on the outside of the second connecting plate 4. A plurality of evenly distributed fixing blocks 403 are provided on the outside of the plug-in tube 401 close to the end of the second connecting plate 4. The length of the fixing blocks 403 is greater than the length of the connecting column 303.
