The lower retainer 1102 is connected to an upper retaining ring 1104 by a bolt assembly; this allows for a firm fixation of the pipe body 10, while facilitating installation and disassembly, thus improving the flexibility and ease of use of the pipe connector.

[0033] like Figure 1 and Figure 6 As shown, in a preferred embodiment, based on the above method, the adjustable support structure 12 further includes a support block 1201 fixed at the center of the main tube 1. Threaded posts 1202 are installed at both ends of the bottom of the support block 1201. A base plate 1203 is fixedly connected to the bottom end of the threaded posts 1202. Two third nuts 1204 are threadedly connected to the threaded posts 1202.
