A first spring 211 is fixedly provided between the two clamps 210 and the annular block 28.

[0042] A guide rod 212 is fixed on the upper side of the two clamping blocks 210, a fixed block 29 is fixed on the upper side of the annular block 28, and a through slot 213 is symmetrically provided on the fixed block 29, and the through slot 213 is adapted to the guide rod 212, and the two guide rods 212 are respectively slidably arranged along the two through slots 213, and a rotating block 214 is rotatably provided on the upper side of the fixed block 29, and rotating rods 215 rotatably arranged with the guide rod 212 are rotatably provided on both sides of the rotating block 214; a connecting piece 216 is slidably provided on the outer side of the connecting tube 26, and a slide groove 217 is symmetrically provided on both sides of the connecting tube 26, and the connecting piece 216 is slidably arranged along the slide groove 217 to The up and down movement of the connecting member 216 is guided and limited. A pull rope 218 is provided between the clamping block 210 and the connecting member 216 on one side of the connecting tube 26. The pull rope 218 movably passes through the bracket 27 and the annular block 28, so as to guide the pull rope 218. The horizontal part of the pull rope 218 and the rotation connection between the annular block 28 and the bracket 27 are located at the same horizontal height. After the clamping block 210 clamps the centrifuge tube 12, the pull rope 218 is in a certain relaxed state so as not to hinder the rotation between the annular block 28 and the bracket 27 during centrifugation, and thus not to hinder the tilting state of the centrifuge tube 12 during centrifugation.

[0043] The user presses the thumb against the connecting tube 26 and pulls the connecting piece 216 upward with the other two fingers, so that the connecting piece 216 moves up along the slide groove 217, thereby pulling the multiple pull ropes 218, so that the clamping block 210 on one side of the connecting tube 26 moves close to the inner wall of the annular block 28, and the guide rod 212 moves along the through groove 213, so that the rotating rod 215 and the rotating block 214 rotate, and the transmission of the rotating rods 215 and the rotating block 214 on both sides can make the clamping block 210 on the other side move close to the inner wall of the annular block 28, that is, the clamping blocks 210 on both sides move away from each other, the first spring 211 is compressed, and the bracket 27 is moved to the placement rack. 25, so that each pair of clamping blocks 210 respectively corresponds to the multiple centrifuge tubes 12 placed on the placement rack 25, and then the bracket 27 is moved downward to move each pair of clamping blocks 210 to the two sides of each centrifuge tube 12, and the fixing block 29 is pressed against the sealing plug 14, and then the connecting piece 216 is loosened.

A second spring 220 fixed to the connecting tube 26 is fixed on one side of the block 219. A pressing plate 221 is fixed on the upper side of the block 219. The pressing plate 221 moves upward and penetrates the bracket 27, and can slide along the bracket 27 close to the groove 222. The two side surfaces of the pressing plate 221 are set as an arc shape that matches the connecting tube 26. The two sides of the connecting tube 26 are provided with grooves 222 that match the pressing plate 221. A socket 223 that matches the connecting tube 26 is set on the upper side of the rotating frame 21. The two sides of the socket 223 are symmetrically provided with slots 224 that match the block 219 and the pressing plate 221.

After the connecting tube 26 is completely inserted into the insertion hole 223, the blocking block 219 is clamped into the clamping groove 224 under the elastic force of the second spring 220, so that the connecting tube 26 can be conveniently fixed on the rotating rack 21, and then, the rotating rack 21 is driven to rotate by the centrifuge body 11 to centrifuge the blood sample in the centrifuge tube 12;

[0046] After centrifugation is completed, the pressing plates 221 on both sides can be pressed so that the pressing plates 221 drive the block 219 to move to the inner side of the connecting tube 26, and the pressing plates 221 move into the groove 222, and lift the connecting tube 26 upward, so that multiple centrifuge tubes 12 can be taken out from the centrifuge body 11 at the same time, and then the multiple centrifuge tubes 12 taken out can be clamped and placed on the placement rack 25, and the clamping effect on the centrifuge tubes 12 can be released, so that multiple centrifuge tubes 12 on another placement rack 25 can be clamped and placed in the centrifuge body 11 to centrifuge the next group of blood samples, and the centrifuge tubes 12 placed on the placement rack 25 after centrifugation are completed can be clamped out and subsequently taken out on the placement rack 25.

[0047] Embodiment 3

[0048] The auxiliary component 3 includes a sliding member 31 slidably arranged with the rotating frame 21. The rotating frame 21 is located at the lower side of the sliding member 31 and is fixedly provided with first airbags 38 at equal intervals around the circumference. The plurality of first airbags 38 correspond to the plurality of sleeves 13 respectively. The inner sides of the plurality of sleeves 13 are fixedly provided with second airbags 312 and third airbags 313. One side of the plurality of first airbags 38 is fixedly connected with a three-way pipe 39. Both ends of the plurality of three-way pipes 39 are fixedly connected with a first connecting pipe 310 and a second connecting pipe 311 respectively. The first connecting pipe 310 is fixedly connected with the second airbag 312, and the second connecting pipe 311 is fixedly connected with the third airbag 313. The first connecting pipe 310 and the second connecting pipe 311 are both configured as hoses so as not to hinder the inclination of the sleeve 13.

[0049] A limiting groove 37 is provided at the lower side of the rotating frame 21, and the sliding member 31 is slidably arranged along the limiting groove 37. A third spring 32 fixed to the rotating frame 21 is fixedly arranged at the upper side of the sliding member 31. A pressure rod 33 is slidably arranged at the middle part of the rotating frame 21. Initially, the lower side of the pressure rod 33 abuts against the upper side of the sliding member 31. Slide blocks 34 are fixedly arranged on both sides of the pressure rod 33. Guide grooves 35 adapted to the slide blocks 34 are provided on both inner sides of the rotating frame 21. A notch 36 is provided on the upper side of the horizontal section of the guide groove 35.

[0050] After the connecting tube 26 is clamped and fixed on the rotating frame 21 and the centrifuge tube 12 is placed in the sleeve 13, the pressure rod 33 passes through the cavity in the middle of the connecting tube 26. By pressing the pressure rod 33 downward, the slider 34 moves downward along the guide groove 35, which will cause the pressure rod 33 to press the sliding member 31 downward and press the first air bag 38, so that the gas in the first air bag 38 enters the first connecting tube 310 and the second connecting tube 311 through the three-way pipe 39, and then enters the second air bag 312 and the third air bag 313, so that the second air bag 312 and the third air bag 313 are expanded. The expansion of the second air bag 312 can stabilize the side of the centrifuge tube 12 in the sleeve 13, and the expansion of the third air bag 313 can stabilize the bottom of the centrifuge tube 12, and can be combined with the clamping effect of the clamping block 210 on the centrifuge tube 12, and the fixing block 29 on the sealing plug 1 The pressing effect of 4 can maintain the stability of the centrifuge tube 12 during the centrifugation process, prevent the centrifuge tube 12 from shaking in the sleeve 13, and affect the centrifugal effect of the blood. When the slider 34 slides to the bottom end of the vertical section of the guide groove 35, the pressure rod 33 cannot continue to move downward, and the pressure rod 33 is rotated to make the slider 34 slide along the horizontal section of the guide groove 35. After sliding to the inner end of the horizontal section of the guide groove 35 and cannot continue to rotate, the pressure rod 33 is released. Under the elastic force of the third spring 32, the sliding member 31 drives the pressure rod 33 to move upward, so that the slider 34 is pressed against the notch 36. The notch 36 limits the position of the slider 34 and the pressure rod 33, so as to keep the pressure rod 33 against the sliding member 31, and then keep the sliding member 31 against the first airbag 38, so as to keep the second airbag 312 and the third airbag 313 inflated.

[0051] After centrifugation is completed, the pressure rod 33 is pressed downward to make the slider 34 disengage from the groove 36 downward, and the pressure rod 33 is rotated in the opposite direction. Then, under the elastic force of the third spring 32, the slider 31 is moved up and reset, and drives the pressure rod 33 to move up. The slider 34 slides upward along the vertical section of the guide groove 35, thereby releasing the pressing effect of the slider 31 on the first airbag 38, allowing the gas in the second airbag 312 and the third airbag 313 to flow back into the first airbag 38, so as to release the stabilizing effect of the second airbag 312 and the third airbag 313 on the centrifuge tube 12.

[0052] The side end of the sliding member 31 is provided with a connecting rod 314 that is rotatable around the circumference at equal intervals, and a sliding rod 315 is rotatably provided on the lower side of the connecting rod 314. An arc block 316 is fixedly provided at one end of the sliding rod 315. A sliding sleeve 317 is slidably provided on the outer side of the sliding rod 315. A fourth spring 319 is fixedly provided between the sliding sleeve 317 and the arc block 316. A supporting rod 318 fixedly provided on the lower side of the sliding sleeve 317 and the rotating frame 21 is fixedly provided. When the sliding member 31 moves downward, the connecting rod 314 can make the sliding rod 315 slide away from the rotating frame 21, so that the sliding member 31 can pass through the arc block 31 6, push the lower side of the sleeve 13 away from the rotating frame 21, so that the annular block 28 and the bracket 27 rotate, the connecting block 22 rotates, and the support shaft 23 slides along the arc groove 24, so that the sleeve 13 and the centrifuge tube 12 therein are in an inclined state to improve the effect of blood centrifugation. After the centrifugation is completed, under the elastic force of the third spring 32 and the fourth spring 319, the sliding rod 315 and the connecting rod 314 are reset, and the sleeve 13 is restored to a vertical state, so that multiple centrifuge tubes 12 can be taken out upward at the same time through the pick-and-place assembly 2.
