2: meanwhile, when the outer crystallization tube 43 and the inner crystallization tube 42 are filled with liquid nitrogen, the liquid nitrogen piston 11 moves to the leftmost end to press the limit spring 18, thereby releasing the limit pull rope 17, thereby driving the crystallization slider 64 to drive the lower bevel gear 14 to move upwards to engage with the upper bevel gear 62, thereby driving the lower bevel gear 14 to rotate, thereby driving the lead screw 48 to rotate, thereby driving the right slider 61 to drive the moving block 51 to move downwards through the external thread of the right slider 61, thereby continuously scraping the crystallized nano-materials on the outer crystallization tube 43 and the inner crystallization tube 42 down and dropping the nano-materials into the collection device 32 through the funnel 33 at the lower end of the generation cavity 23, simultaneously driving the driven ring 37 to move downwards through the rigid rope when the driving block 44 moves downwards, when the moving block 51 descends to the lowermost position, the driving ring 44 moves to the lowermost end of the inner crystallization tube 42, and the trigger slider 71 at the lower end of the moving block 51 is pressed by the lower limit plate 50 at the lower end of the lead, thereby tensioning the trigger pull rope 55, pulling the right slider 61 at the rear end of the moving block 51, thereby loosening the right linkage pull rope 54, driving the right slider 61 at the front end of the moving block 51 to move forward through the threaded cavity 58 at the front end of the moving block 51, thereby disengaging the threads on the right slider 61 from the lead screw 48, simultaneously loosening the reversing pull rope 59 on the right slider 61 at the front end of the moving block 51, thereby driving the left slider 60 at the front end of the moving block 51 to move backward through the left spring 53 at the front end of the moving block 51, and driving the left slider 60 at the rear end of the moving block 51 to move forward through the left linkage pull rope 52, thereby engaging the threads on the left slider 60 with the lead screw 48, thereby driving the left slider 60 to drive the moving block 51 to move upward, thereby driving the driving ring 44 to move upward, when the driving ring 44 moves upward, the driving ring 37 moves upward relative to the funnel 33 due to the friction between the inner crystal tube 42, thereby enabling the tapered block 56 at the lower end, thereby expanding the driving ring 44, and moving the driving ring 44 to move the driven ring 37 upwards to the upper part of the outer crystallizing tube 43, thereby completing the up-and-down movement of the driving ring 44 on the outer crystallizing tube 43 and the inner crystallizing tube 42, so that the crystallized nano-material on the outer crystallizing tube 43 and the inner crystallizing tube 42 is continuously scraped by the driving ring 44 and falls into the collecting device 32.

3: after crystallization is completed, the outer cooling cavity 47 is reversed to drive the power shaft 36 to be reversed, so that the power gear 35 is driven to be reversed, the push-pull toothed plate 19 is driven to move rightwards, the liquid nitrogen piston 11 is driven to move rightwards, liquid nitrogen in the inner crystallization tube 42 and the outer crystallization tube 43 is sucked back into the liquid nitrogen cavity 12, the liquid nitrogen cavity 12 and the balance channel 13 are reset under the action of the lower spring 45 and the upper spring 39, and the device is driven to reset.
