Further, the sleeve-shaped structure is an expansion sleeve; the front end of the female connecting piece is provided with a first connecting column, the center of the first connecting column is provided with a column groove, and the inner wall of the column groove is provided with threads; the front end of the sub-connecting piece is provided with a second connecting column, the second connecting column is provided with a columnar bulge, the outer wall of the columnar bulge is provided with threads, and the connection between the main connecting piece and the sub-connecting piece is realized by screwing the columnar bulge of the sub-connecting piece into the columnar groove of the main connecting piece; the columnar bulge of the sub-connecting piece is provided with an inward sinking groove in the center, the bottoms of the columnar grooves of the female connecting piece and the bottoms of the inward sinking grooves of the sub-connecting piece are respectively provided with a threaded through hole, and the threaded through holes are respectively screwed with an inward pushing bolt; the front end part of the inner pushing bolt is provided with a bolt conical head for expanding the expansion sleeve.
Further, the outer wall of the expansion sleeve is provided with a ring groove for increasing friction force.
Further, an elastic sealing ring is arranged in the ring groove.
Further, the rear end surfaces of the first connecting column and the second connecting column are respectively provided with a plurality of reinforcing protrusions; a plurality of reinforcing gaps are formed in the end face of the steel pipe body; the reinforcing convex card is embedded into the reinforcing notch.
The utility model has the advantages and beneficial effects that:
1. the steel pipe body does not need to be milled with threads, so that the situation that the steel pipe cannot be used due to thread sliding is avoided, and once the thread of the primary-secondary connecting piece slides, the primary-secondary connecting piece is directly replaced;
2. the connection between the steel pipes with different pipe inner diameters can be realized; when the inner diameters of the two steel pipes to be connected are different, the expansion sleeve of the primary-secondary connecting piece can be in interference fit with the inner walls of the two steel pipes respectively.
