The movement of the first extrusion block 19 will squeeze the flask 4 to move. The movement of the flask 4 will drive the clamping block 138 to move. The movement of the clamping block 138 drives the moving rod 137 to move inside the fixed frame 136. The movement of the flask 4 drives the moving block 16 to slide along the fixed rod 17. The movement of the flask 4 will squeeze the second extrusion block 20, so that the second extrusion block 20 drives the T-shaped block to move inside the extrusion groove 18. Then the turntable 14 continues to rotate, so that the second extrusion block 20 drives the inclined surface of the linkage block 21 to contact the inclined surface of the extrusion bar 22. According to the same principle as above, the second extrusion block 20 will squeeze the flask 4 back to its original position.

[0032] like Figure 1 and Figure 8As shown, the rotating assembly 11 includes a slider 111 movably connected to the inside of the first fixed block 9, one end of the slider 111 is fixedly connected to a rack 112, one end of the rack 112 is fixedly connected to a linkage plate 113, one end of the linkage plate 113 is fixedly connected to an electric telescopic rod 114, one end of the electric telescopic rod 114 is fixedly installed inside the housing 1, one end surface of the rack 112 is meshedly connected to a gear 115, the gear 115 is fixedly connected to a linkage rod 116, the top of the linkage rod 116 is fixedly connected to the bottom of the turntable 14, the electric telescopic rod 114 is started by the control panel, and the electric telescopic rod 114 is retracted. The linkage plate 113 is moved by the contraction, and the linkage plate 113 moves and drives the rack 112 to move synchronously. The rack 112 moves and drives the slider 111 to slide inside the first fixed block 9. With the movement of the rack 112, the gear 115 is driven to rotate. The rotation of the gear 115 drives the linkage rod 116 to rotate synchronously. The rotation of the linkage rod 116 drives the turntable 14 to rotate synchronously inside the lifting plate 7. The rotation of the turntable 14 drives the moving block 16 and the flask 4 to rotate synchronously. The rotation of the flask 4 can fully mix the sample to be tested and the reaction reagent inside, thereby effectively improving the reaction rate between the sample to be tested and the reaction reagent.

[0033] like Figure 1 and Figure 6 As shown, the bottom end of the lifting plate 7 is located on both sides of the linkage rod 116 and is fixedly connected to the first spring telescopic rod 23. The bottom end of the first spring telescopic rod 23 is fixedly installed inside the shell 1. A rigid chain telescopic mechanism 24 is fixedly installed inside the shell 1 below the gear 115. The output end of the rigid chain telescopic mechanism 24 is fixedly connected to the lifting plate 25. After the flask 4 is rotated, the rigid chain telescopic mechanism 24 is started. The output end of the rigid chain telescopic mechanism 24 drives the lifting plate 25 to move upward. The lifting plate 25 will contact the gear 115 and drive the gear 115 to move upward. The movement of the gear 115 drives the linkage rod 116 and the lifting plate 7 to move synchronously, thereby completing the resetting of the lifting plate 7.

[0034] like Figure 1 and Fig. 9As shown, the clamping assembly 13 includes an air pipe 131 fixedly connected to the interior of the positioning block 12, a compression block 132 is movably provided inside one end of the air pipe 131, a movable rod 133 is movably connected to the interior of the air pipe 131 at the other end, a second spring telescopic rod 135 is fixedly connected to the interior of the other end of the air pipe 131 at the outer position of the movable rod 133, a piston 134 is fixedly connected to one end of the movable rod 133, the outer surface of the piston 134 is movably connected to the interior of the air pipe 131, a fixing frame 136 is fixedly connected to the other end of the movable rod 133, a moving rod 137 is movably connected to both ends of the fixing frame 136, a clamping block 138 is fixedly connected between the two moving rods 137, an auxiliary block 139 is fixedly connected to one end of the clamping block 138, and an auxiliary block 139 is fixedly connected to one end of the clamping block 138. The outer surface of block 139 is movably connected to the inside of the fixing frame 136. When the lifting plate 7 moves downward, the bottom end of the lifting plate 7 will squeeze the compression blocks 132 located on both sides, and the compression blocks 132 will move downward inside the air pipe 131. The compression blocks 132 will squeeze the gas, and the gas flowing along the air pipe 131 will squeeze the piston 134, driving the piston 134 to move in the direction of the second spring telescopic rod 135. The movement of the piston 134 will squeeze the second spring telescopic rod 135 and drive the movable rod 133 to move synchronously. The movement of the movable rod 133 will drive the fixing frame 136 and the clamping block 138 to move synchronously. As the clamping block 138 moves, the two opposite clamping blocks 138 will contact and clamp the neck of the flask 4 to prevent the flask 4 from tipping over when it rotates.

[0035] like Figure 1 and Figure 8 As shown, the first fixing block 9 is located at the back of the second fixing block 10, and a descending groove is provided inside the positioning block 12 at the position corresponding to the limit block 8, to ensure that the position of the lifting plate 7 will not shift when it descends, thereby improving the stability of the lifting plate 7 when it moves.

[0036] like Figure 1 and Fig.11 As shown, the outer surface of the turntable 14 is fixedly connected to a limiting ring, and the outer surface of the limiting ring is rotatably connected to the inside of the lifting plate 7 to prevent the turntable 14 from escaping from the inside of the lifting plate 7. The limiting ring plays a limiting role on the turntable 14.

[0037] like Figure 1 and Fig.11 As shown, the bottom ends of the first extrusion block 19 and the second extrusion block 20 are fixedly connected with T-shaped blocks. The T-shaped block at the bottom end of the first extrusion block 19 is located at the edge position, and the T-shaped block at the bottom end of the second extrusion block 20 is located at the midpoint position, ensuring that the first extrusion block 19 and the second extrusion block 20 drive the T-shaped blocks to move synchronously inside the extrusion groove 18, so that it can drive the flask 4 to rotate back and forth left and right, ensuring a linkage effect between the first extrusion block 19 and the second extrusion block 20.

[0038] like Figure 1 and Fig.10As shown, one end of the linkage block 21 and the extrusion strip 22 are both provided with an inclined surface.

[0039] Working principle: In actual use of the device, the sample to be tested is first placed in the flask 4, and then the reaction reagent is added to the flask 4. Then, the flask 4 is placed on the top surface of the moving block 16 and is located between the first extrusion block 19 and the second extrusion block 20. Due to the action of gravity, the flask 4 will exert a force on the moving block 16, and the moving block 16 will simultaneously exert a force on the lifting plate 7, and the lifting plate 7 will simultaneously exert a force on the first spring telescopic rod 23, so that the movable end of the first spring telescopic rod 23 contracts and drives the lifting plate 7 to move downward. The downward movement of the lifting plate 7 drives the linkage rod 116 and the gear 115 to move downward synchronously. The lifting plate 7 moves downward, driving the moving block 16 and the flask 4 to move downward synchronously. The lifting plate 7 moves downward, driving the limit block 8 to move downward along the descending groove. As the lifting plate 7 moves, the bottom end of the lifting plate 7 will squeeze the compression blocks 132 on both sides. The compression blocks 132 will move downward inside the air pipe 131. The compression blocks 132 will squeeze the gas. The gas flows along the air pipe 131 to squeeze the piston 134, driving the piston 134 to move in the direction of the second spring telescopic rod 135. The movement of the piston 134 will squeeze the second spring telescopic rod 135 and drive the movable rod 133 to move synchronously. The movement of the movable rod 133 will drive the fixed rod 133 to move synchronously. The fixed frame 136 and the clamping block 138 move synchronously. As the clamping block 138 moves, the two opposing clamping blocks 138 will contact and clamp the neck of the flask 4. As the lifting plate 7 drives the gear 115 to move downward, the gear 115 will mesh with the rack 112. Then, the electric telescopic rod 114 is started through the control panel. The electric telescopic rod 114 contracts and drives the linkage plate 113 to move. The linkage plate 113 moves and drives the rack 112 to move synchronously. The rack 112 moves and drives the slider 111 to slide inside the first fixed block 9. As the rack 112 moves, the gear 115 will rotate. The gear 115 rotates. The linkage rod 116 is driven to rotate synchronously, and the rotation of the linkage rod 116 drives the turntable 14 to rotate synchronously inside the lifting plate 7. The rotation of the turntable 14 drives the moving block 16 and the flask 4 to rotate synchronously. When the flask 4 rotates, the clamping blocks 138 on both sides can limit the flask 4 to prevent it from tipping over, and the gravity can be used to realize the single rotation of a certain flask 4. The rotation of the flask 4 can quickly and fully mix the internal sample to be tested and the reaction reagent, and the clamping can prevent the flask 4 from tipping over when rotating, thereby improving the reaction rate between the sample to be tested and the reaction reagent, so that the microorganisms can be quickly separated from the sample to be tested, and the precipitation rate of the microorganisms is improved;

[0040] Then, as the turntable 14 rotates, the first extrusion block 19 and the second extrusion block 20 will be driven to rotate synchronously, and the rotation of the first extrusion block 19 and the second extrusion block 20 will drive the linkage block 21 to rotate synchronously. As the first extrusion block 19 drives the linkage block 21 to rotate, the inclined surface of the linkage block 21 will first contact the inclined surface of the extrusion bar 22, and the extrusion bar 22 will apply a force to the linkage block 21, so that the first extrusion block 19 drives the T-shaped block to move inside the extrusion groove 18. The movement of the first extrusion block 19 will squeeze the flask 4 to move, and the movement of the flask 4 will drive the clamping block 138 to move, and the clamping block 138 will move. 8 moves and drives the moving rod 137 to move inside the fixed frame 136, and the movement of the flask 4 drives the moving block 16 to slide along the fixed rod 17. The movement of the flask 4 will squeeze the second squeezing block 20, so that the second squeezing block 20 drives the T-shaped block to move inside the squeezing groove 18. Then the turntable 14 continues to rotate, so that the second squeezing block 20 drives the inclined surface of the linkage block 21 to contact the inclined surface of the squeezing bar 22. According to the same principle as above, the second squeezing block 20 squeezes the flask 4 back to its original position. With the rotation of the turntable 14, the first squeezing block 19 and the second squeezing block 20 can drive the flask 4 to move left and right. The flask 4 moves back and forth, causing the sample to be tested and the reaction reagent inside the flask 4 to shake back and forth, effectively improving the reaction rate of the sample to be tested and the reaction reagent, so that the sample to be tested can be quickly separated from the microorganisms, and the precipitation rate of the microorganisms is improved. Then, the rigid chain telescopic mechanism 24 is started through the control panel, and the output end of the rigid chain telescopic mechanism 24 drives the lifting plate 25 to move upward. The lifting plate 25 will contact the gear 115 and drive the gear 115 to move upward. The movement of the gear 115 drives the linkage rod 116 and the lifting plate 7 to move synchronously. As the lifting plate 7 moves upward, due to the Then, a force is applied to the compression block 132, and the force at one end of the piston 134 is reduced. Under the action of the second spring telescopic rod 135, the piston 134 is driven to move away from the end of the piston 134. The movement of the piston 134 drives the fixed frame 136 and the clamping block 138 to move synchronously. At this time, the clamping block 138 contracts and no longer clamps the neck of the flask 4. Then the lifting plate 7 drives the moving block 16 and the flask 4 to continue to move upward. The flask 4 will be connected to the connecting tube 3, and the extraction mechanism will extract the microorganisms inside the flask 4 through the connecting tube 3 and enter the detection mechanism to complete the detection.
