[0022] like Figure 1-3As shown, a positioning cap 14 is fixedly installed on the top surface of the interior of the sterilization box 1, and the interior of the positioning cap 14 is rotatably connected to the top of the rotating shaft 2, and a fixed gear 15 is fixedly connected to the outer surface of the positioning cap 14. A transmission gear 13 is rotatably installed on the top of the four L-shaped fixed rods 4, and the outer surfaces of the four transmission gears 13 are meshed with the outer surface of the fixed gear 15. A turntable 11 is fixedly connected to the top of the four connecting shafts 5, and the outer surfaces of the four turntables 11 are transmission-connected with a transmission belt 12, and the inner surfaces of the transmission belt 12 are transmission-connected with the outer surfaces of the four transmission gears 13 respectively. By setting the positioning cap 14, the rotating shaft 2 can be prevented from being skewed. By setting the fixed gear 15, the rotating shaft 2 can drive the transmission gear 13 to rotate during the rotation process. By setting the transmission belt 12, the turntable 11 can be rotated, so that the clamping head 6 connected to the connecting shaft 5 can rotate during the rotation process.

[0023] like Figure 4 As shown, the clamping head 6 includes a fixed barrel 17, the outer surface of which is penetrated by a guide through hole 18, a placing table 19 is slidably installed inside the fixed barrel 17, a rotating ring 20 is rotatably installed at the bottom end of the placing table 19, four adjusting columns 21 are fixedly connected to the outer surface of the rotating ring 20, and the outer surfaces of the four adjusting columns 21 are respectively slidably connected inside the four guide through holes 18, and a No. 2 return spring 24 is fixedly connected to the bottom surface of the four fixed barrels 17, and the top ends of the four No. 2 return springs 24 are respectively in contact with the bottom ends of the four placing tables 19, wherein, by setting the rotating ring 20, the downward force on the placing table 19 can be converted into a rotational force under the action of the guide through hole 18, and by setting the No. 2 return spring 24, a reaction force can be provided for the downward pressure, so that the object is fixed more stably.

[0024] like Figure 4 As shown, the top of the fixed barrel 17 is rotatably connected to a rotating table 22, and the bottom end of the rotating table 22 is fixedly connected to four driven rods 23. The bottom ends of the four driven rods 23 all pass through the top of the fixed barrel 17 and are movably arranged. The outer surfaces of the four driven rods 23 are respectively slidably connected to the outer surfaces of the four adjusting columns 21. By setting the driven rods 23, the adjusting columns 21 can push the rotating table 22 to rotate during the movement.

The support plate 9 slides inside the square groove 7 under the action of the downward pressure, and the No. 1 return spring 10 is forced to shrink. After the staff puts the other end of the hemodialyzer into another clamping head 6, the support plate 9 is released. The No. 1 return spring 10 releases elastic potential energy to lift the support plate 9. The blood pressure dialyzer is squeezed by the upper and lower clamping heads 6 and exerts a reaction force, exerting a reaction force on the placement table 19 in the clamping head 6. The placement table 19 is forced to move, so that the adjustment The column 21 moves under the action of the guide through hole 18 and pushes the rotating table 22 connected to the driven rod 23 to rotate. During the rotation of the rotating table 22, the clamping rod 25 is driven to rotate to clamp and fix the hemodialyzer. During the sterilization process, the reduction motor 16 rotates to drive the rotating shaft 2 to rotate. During the rotation of the rotating shaft 2, the transmission gear table 13 rotates on itself under the action of the fixed gear 15 and drives the connecting shaft 5 to rotate through the transmission belt 12, so that the hemodialyzer can rotate while following the rotation of the rotating shaft 2.
