[0010] As a further optimization scheme of the utility model, the top and bottom of the steel pipe body are provided with a plurality of threaded holes matched with the positioning holes, and every two adjacent threaded holes are arranged at equal intervals.

[0011] As a further optimization scheme of the utility model, the positioning hole is internally screwed with a bolt, and the limiting hole and the threaded hole are matched with the bolt.

[0012] The utility model discloses the beneficial effect lies in: the utility model discloses the process of using can adjust two adjacent steel pipe body insertion to the depth of the connecting pipe inside according to the specific use demand, thereby can shorten and lengthen the length of the whole welded steel pipe assembled together, to satisfy the specific use demand, improve the flexibility of the welded steel pipe use, thereby more convenient for people to use.
