Specifically, the driving mechanism comprises a screw rod 10 rotatably connected to the pipe body, a guide rod 11 connected to the pipe body, a first bevel gear 12 connected to the screw rod, a transmission rod 13 rotatably connected to the housing, a second bevel gear 14 connected to the inner end of the transmission rod, and a handle 15 connected to the outer end of the transmission rod, the screw rod 10 is rotatably connected to the cover 9, the first bevel gear 12 is meshed with the second bevel gear 14, and the first bevel gear 12 and the second bevel gear 14 are both located in the cover 9, and the screw rod 10 is provided with reverse threads on both sides of the cover 9, one side of the two sliding sleeves 2 is respectively threadedly connected to the two ends of the screw rod 10, and the other side of the two sliding sleeves 2 is slidably connected to the guide rod 11. The handle 15 is turned to drive the transmission rod 13 to rotate. The transmission rod 13 drives the screw rod 10 to rotate through the cooperation of the second bevel gear 14 and the first bevel gear 12. Since the two sides of the screw rod 10 are opposite threads, the screw rod 10 will drive the two sliding sleeves 2 to move relative or oppositely during rotation.

The outer wall of the connecting pipe 5 is provided with an annular protrusion 6, and the inner wall of the groove 4 is provided with an annular groove 7. The annular protrusion 6 is rotatably arranged in the annular groove 7. The connecting pipe 5 passes through the end of the pipe body 1, and the passing end is connected to a flange 8. The flange 8 is slidably connected to the annular groove 7 through the annular protrusion 6, and the flange can be rotated to adjust the position of the mounting hole.

[0026] The working principle of this embodiment is:

[0027] When connecting two pipes, the flange 8 at one end of the pipe body 1 is connected to the flange on one of the pipes, and then the flange 8 at the other end of the pipe body 1 is rotated to align the flange 8 with the flange on the other pipe before connecting, which improves the convenience of pipe connection and effectively solves the problem of inconvenient installation caused by misalignment of the flange holes on the two pipes.

[0028] By driving the two sliding sleeves 2 to move relative or oppositely through the driving mechanism, the two flanges 8 can be moved relative or oppositely to adapt to the distance between the two pipes, thereby facilitating the installation of the two pipes and improving the convenience and adaptability of the installation.
