[0031] Please see Figures 1-3 As shown, this embodiment is a novel affinity chromatography column, comprising:

[0032] Chromatography column 11;

[0033] The positioning component includes a side plate 21, a support frame 22, a support plate 23, a positioning half ring 24, a limiting ring 25, a slider 26, a insertion ring 27, a slot 28, a groove 29, and a drainage tube 291. The drainage tube 291 is connected to the bottom of the chromatography column 11. The lower parts of both sides of the outer surface of the chromatography column 11 are connected to the side plate 21. The inside of the side plate 21 is provided with a groove 29. The slider 26 is movably connected to the inside of the groove 29. The support frame 22 is connected to one side of the outer surface of the slider 26. The positioning half ring 24 is connected to the lower part of one side of the support frame 22. The top of the drainage tube 291 is connected to the support plate 23. The support plate 23 is connected to the bottom of the chromatography column 11. The positioning half ring 24 is clamped and connected to the bottom of the support plate 23.

[0034] The drainage tube 291 is installed at the bottom of the chromatography column 11, and the support plate 23 is attached to the bottom of the chromatography column 11. Then, the slider 26 slides inside the groove 29. According to the position of the support plate 23, the positioning half ring 24 is moved and clamped on both sides of the outer surface of the support plate 23 to fix the support plate 23.

[0035] The top of the positioning semi-ring 24 is connected to a limiting ring 25, which is connected to both sides of the outer surface of the support plate 23;

[0036] After the positioning half-ring 24 is clamped on both sides of the outer surface of the support plate 23, the limiting ring 25 will simultaneously fit and fasten to both sides of the support plate 23 for positioning.

[0037] The bottom of the chromatography column 11 is symmetrically provided with slots 28, and the top of the limiting ring 25 is connected to a plug ring 27, which is inserted into the inside of the slot 28.

[0038] After the positioning half-ring 24 is clamped on the outside of the support plate 23, the insertion ring 27 is simultaneously inserted into the inside of the slot 28 for fixation.

[0039] It also includes a fixing component, which includes a moving groove 31, a moving block 32, a fixing hole 33, a fixing rod 34 and a fixing ring 35. The upper part of the inner surface of the sliding groove 29 is provided with a fixing hole 33, the top of the slider 26 is connected to a fixing rod 34, the fixing rod 34 is inserted into the inside of the fixing hole 33, and the outer surface of the fixing rod 34 is fastened to a fixing ring 35.

[0040] The fixing rod 34 is inserted into the fixing hole 33, and then the fixing ring 35 is fastened to the outside of the fixing rod 34 to fix the position of the moving positioning half ring 24.

[0041] The inner surface of the slide groove 29 has two moving grooves 31 at both ends, and the outer surface of the slider 26 has two moving blocks 32 connected to both ends. The moving blocks 32 are movably connected inside the moving grooves 31.

[0042] When the slider 26 moves inside the slide groove 29, its moving block 32 moves simultaneously inside the moving groove 31, providing support.

[0043] The working principle is as follows: First, the drainage tube 291 is installed at the bottom of the chromatography column 11, and the support plate 23 is attached to the bottom of the chromatography column 11. Then, the slider 26 slides inside the groove 29. According to the position of the support plate 23, the positioning half ring 24 is moved and clamped on both sides of the outer surface of the support plate 23, while the insertion ring 27 is inserted into the slot 28. The fixing rod 34 is fixed inside the fixing hole 33, and the fixing ring 35 is fastened to the outside of the fixing rod 34 to fix the position of the positioning half ring 24 and fix the support plate 23. After a long period of drainage, this prevents the drainage tube 291 from becoming loose between the chromatography column, which could even lead to the drainage tube 291 detaching in severe cases, thus improving the stability during drainage. Finally, the fixing ring 35 is loosened, and the slider 26 moves inside the groove 29, while the moving block 32 moves inside the moving groove 31, moving the positioning half ring 24 to separate it from the support plate 23, so that the drainage tube 291 can be removed.

[0044] Please see Figure 1 , Figure 4 As shown, this embodiment is based on the above embodiment 1, and further includes a cleaning component. The cleaning component includes a top cover 41, a damping ring 42, a damping rod 43, a handle 44, a support rod 45, a scraper, a collar 47, an internal threaded ring 48, a threaded rod 49, and a handle 491. The top cover 41 is connected to the top of the chromatography column 11. The damping ring 42 is connected to the middle of the top of the top of the top cover 41. The damping rod 43 is connected inside the damping ring 42. The handle 44 is fixedly connected to the top of the damping rod 43. The scraper is connected to the bottom of the damping rod 43. The collar 47 is connected to the middle of the inner surface of the scraper ring 46. The collar 47 is connected to the lower part of the outer surface of the damping rod 43 by a sleeve. Multiple support rods 45 are connected between the collar 47 and the scraper.

[0045] The user holds the handle 44 and moves the damping rod 43 up and down repeatedly inside the damping ring 42, using the internal scraper to scrape off the liquid adhering to the inner wall of the chromatography column 11.

[0046] An internal threaded ring 48 is connected to the middle of one end of the outer surface of the collar 47. A threaded rod 49 is connected inside the internal threaded ring 48. A handle 491 is rotatably connected to the outer end of the threaded rod 49.

[0047] The scraper ring 46 can be fixed after installation by being fastened to the outside of the damping rod 43 by the threaded rod 49.

[0048] The working principle is as follows: After prolonged use, some liquid will adhere to the inner wall of the chromatography column 11. The damping rod 43 is inserted into the damping ring 42, and then the collar 47 is fitted onto the bottom of the damping rod 43. The threaded rod 49 is rotated and clamped to the outside of the damping rod 43, which can fix the scraper ring 46 after installation. The user holds the handle 44 and moves the damping rod 43 up and down repeatedly inside the damping ring 42. The internal scraper is used to scrape off the liquid adhering to the inner wall of the chromatography column 11, improving the convenience of cleaning.
