[0020] Embodiment 1: Refer to Figures 1-4 , a blood oscillation mixing device, including a base 1, a fixing frame 2 is arranged in the middle of the top of the base 1, a connecting plate 3 is installed on the top of the fixing frame 2, a plurality of rotating shafts 4 are sequentially installed on the connecting plate 3 through bearings, fixing seats 5 are installed on the tops of the plurality of rotating shafts 4, elastic sleeves 6 are arranged in the plurality of fixing seats 5, the inner diameters of the plurality of elastic sleeves 6 are different, transmission wheels 7 are installed at the bottoms of the plurality of rotating shafts 4, the plurality of transmission wheels 7 are meshed with each other, a servo motor 8 is installed on the base 1, and the output shaft of the servo motor 8 extends to the fixing frame 2 and is provided with a rotating disc 9, and a connecting mechanism is arranged between the rotating disc 9 and one of the rotating shafts 4;

[0021] The connecting mechanism includes a connecting rod 10 installed on the top edge of the rotating disc 9, a slide rail 21 installed on the fixing frame 2, a rotating rod 11 installed on the fixing frame 2 through a bearing, a moving strip 12 is slidably arranged on the slide rail 21, a rack 13 is installed on one side of the moving strip 12, a gear 14 is installed on the outer side of the rotating rod 11, the rack 13 is matched with the gear 14, one end of the rotating rod 11 is installed on one end of one of the rotating shafts 4, one end of the moving strip 12 is hinged with a crank 15, and one end of the crank 15 is hinged on the connecting rod 10. Wear-resistant coatings are arranged on both the moving strip 12 and the slide rail 21. The set wear-resistant coatings are all formed by nitriding treatment, which improves the mechanical properties of the moving strip 12 and the slide rail 21 and increases the service life of the moving strip 12 and the slide rail 21.

[0022] After squeezing a plurality of test tubes into the plurality of elastic sleeves 6 in sequence, start the servo motor 8. The output shaft of the servo motor 8 will drive the rotating disc 9 to rotate. The rotation of the rotating disc 9 will drive the connecting rod 10 to rotate. The rotation of the connecting rod 10 will pull the crank 15 to move. The movement of the crank 15 will drive the moving strip 12 to move on the slide rail 21, so that the moving strip 12 reciprocates on the slide rail 21. During the reciprocating movement of the moving strip 12, it will drive the rack 13 to reciprocate. The rack 13 makes the gear 14 reciprocate. The reciprocating movement of the gear 14 will drive the rotating rod 11 to reciprocate. The rotating rod 11 will drive one of the rotating shafts 4 to rotate.
