The bottom end of the threaded rod 104 extending out of the threaded hole 105 is connected to an extrusion plate 106.

[0023] Through the above technical solution, the rotary cover 103 on the top of the rotating plate 102 is rotated, and the threaded rod 104 is driven to rotate in the threaded hole 105 through the rotary cover 103. The threaded rod 104 drives the extrusion plate 106 to move downward through the cooperation between the threaded rod 104 and the threaded hole 105, so that the extrusion plate 106 squeezes and fixes the semicircular ring 201 on the outside of the extraction pipe 2, and the extraction pipe 2 is fixed by fixing the semicircular ring 201.
