A limiting hole 12 is provided on the top surface of the protrusion 11.

[0028] In this embodiment, the distillation separation column 1 is segmented, and the multiple segments of the distillation separation column 1 are spliced ​​together by bolts. The inner diameter of the supporting bottom ring 2 is smaller than the inner diameter of the limiting top ring 3. The inner diameter of the limiting top ring 3 is adapted to the outer diameter of the outer convex ring 10, and the connection between the outer convex ring 10 and the limiting top ring 3 is a sliding connection. The insert rod 6 passes through the through hole 5, and the connection between the insert rod 6 and the through hole 5 is a sliding connection. The length and width of the protrusion 11 are adapted to the length and width of the groove 4, and the connection between the protrusion 11 and the groove 4 is a sliding connection. The height of the protrusion 11 is related to the supporting bottom ring 2 and the limiting top ring 3.

Then, the outer protrusion ring 10 and the protrusion 11 are placed on the top surface of the support bottom ring 2. Next, the distillation inner body 9 is rotated so that the protrusion 11 is rotated to the position of the through hole 5. At the same time, the insertion rod 6 is pulled upward by the pull buckle 7. When the position of the insertion rod 6 is consistent with the position of the limiting hole 12, the pull buckle 7 is released. Then, the spring will rebound and pull the insertion rod 6 and the pull buckle 7 downward. Then, the insertion rod 6... It will then be inserted into the limiting hole 12, thereby completing the installation of the distillation internal body 9 and the distillation separation column 1. Disassembly is done in reverse. The supporting bottom ring 2, limiting top ring 3, groove 4, outer convex ring 10, and protrusion 11 facilitate the connection and separation of the distillation internal body 9 and the distillation separation column 1.
