A limit buckle 20 is installed at the end of the pressing rod 19. A compression spring 18 is installed on the outer surface of the pressing rod 19 in the gap of the limit buckle 20. A limit tooth 21 is provided on the side of the clamping rod 5 near the limit buckle 20. The limit buckle 20 is locked inside the limit tooth 21. The clamping rod 5 is limited and fixed by the limit buckle 20. The pressing table 6 can be locked inside the clamping groove 2. The pressing table 6 and the clamping groove 2 have a conical fit.

[0026] like Figure 2-4 As shown, sealing grooves 11 are provided on both sides of the pipe body 1. A sealing gasket 8 is installed inside the sealing groove 11 on one side of the pipe body 1. A compression boss 12 is installed in the middle of the sealing groove 11. The compression boss 12 compresses the sealing gasket 8 to ensure the sealing performance of the connection.

[0027] The working principle of a seamless steel pipe with a connecting mechanism based on Embodiment 1 is as follows: After the present invention is installed, after the adjacent pipe bodies 1 are joined, the side-pulling extrusion rod 19 is pulled, thereby causing the limit buckle 20 to move laterally, separating the limit buckle 20 from the limit tooth 21. Then, the clamping rod 5 is pressed down, thereby causing the extrusion table 6 to move down, thereby inserting the extrusion table 6 into the clamping groove 2, thus fixing the pipe body 1. After completion, the extrusion rod 19 is released, and the limit buckle 20 is squeezed by the extrusion spring 18, thereby inserting the limit buckle 20 into the limit tooth 21, locking the clamping rod 5, thereby fixing the extrusion table 6. Thus, the working process of this equipment is completed.

The positioning buckle 15 is pressed upward and squeezed by the spring 13, so that the positioning buckle 15 is inserted into the positioning groove 22, thereby connecting the pipe bodies 1.
