[0029] The working principle and usage process of the present utility model:

[0030] When in use, the reinforcing ribs 321 of this solution surround the outside of the pipe body 1 to reinforce the pipe body 1, which can prevent the pipe body 1 from bending during use, improve the tensile resistance of the pipe body 1, and extend the service life of the pipe body 1. Moreover, the reinforcing ribs 321 provided in this solution are connected to the inside of the threaded cylinder 23 through the threaded posts 322 at one end thereof, and all four reinforcing ribs 321 are connected in this way.

If you want to disassemble the reinforcing ribs 321, only by simultaneously rotating the four rotating blocks 232 to rotate the four threaded cylinders 23 can the threaded posts 322 be removed from the inside of the threaded cylinders 23, thereby disassembling the reinforcing ribs 321. This makes the overall strength of this solution higher and the service life longer in harsh environments; when multiple pipe bodies 1 need to be connected and used, first insert the insertion pipe 31 on the side wall of the connecting cylinder 3 at one end of one pipe body 1 into the inside of the fixed cylinder 21 at the end of the connecting pipe 2 at one end of another pipe body 1, align the limiting groove 312 with the receiving groove 212, and then turn the screw rod 24 to drive the limiting disk 241 to move downward and insert it into the inside of the limiting groove 312, then the connection and fixation between the two pipe bodies 1 can be completed. By analogy, multiple pipe bodies 1 can be connected and used.
