[0034] Specifically, the ends of the two rectangular columns 5 far away from each other are fixedly connected with a guide slider 38, the sides of the two stands 4 close to each other are provided with a guide slide 39, and the guide slide 38 and the guide slide 39 are along Vertical sliding connection; the telescopic rod 37 includes a sleeve fixedly connected to the bottom of the top plate 35 and a movable rod movably sleeved in the sleeve, and the bottom end of the movable rod extends to the outside of the sleeve and is fixedly connected to the rectangular column 5.
[0035] Specifically, universal balls 18 are rollingly installed on both sides of the bottom of the rotating plate 3, an annular ball groove 19 is provided on the top of the bottom box 1, and the bottom side of the universal ball 18 extends into the annular ball groove 19 and is connected with the annular ball The inner wall of the groove 19 is connected by rolling.
[0036] Specifically, a rotating seat 16 is provided on the bottom inner wall of the bottom box 1, and the bottom end of the rotating column 2 is rotatably mounted on the rotating seat 16; a dust-proof net 13 for dust prevention is installed at the heat dissipation port 12 of the bottom box 1; An H-shaped bracket is fixedly installed at the bottom of the dual-axis stepping motor 9, and the H-shaped bracket is fixedly installed on the bottom inner wall of the bottom box 1; a controller 17 is installed on the bottom inner wall of the bottom box 1, and the left side of the bottom box 1 There is a power socket 7 for external power supply. The front side of the bottom box 1 is provided with a control panel 8. The control panel 8, the two-axis stepping motor 9 and the driving motor 28 are all electrically connected to the controller 17; the control panel 8 is through the controller 17 Start and control the dual-axis stepping motor 9 and the driving motor 28. This is a conventional method in the prior art. Here, no further description is needed.
[0037] In this embodiment, during use, since blood collection bottles 23 of different sizes are set, people can choose a blood collection bottle 23 of appropriate size according to the amount of inspection needed, and then put the collected blood and anticoagulant into the blood collection bottle. In the bottle 23, put the blood sampling bottle 23 into the corresponding container fixing sleeve 22, and use the locking fastener 34 to lock and fix the box cover 20 on the shaking box 6, and use the controller 17 to start the biaxial stepping The motor 9 and the driving motor 28 work at the same time. The left output shaft 14 of the dual-axis stepping motor 9 drives the first cone wheel 14 to rotate, and the first cone wheel 14 drives the rotating column 2 to rotate on the rotating seat 16 through the second cone wheel 15 , The rotating column 2 drives the rotating plate 3 to rotate, and the rotating plate 3 drives the stand 4, the rectangular column 5, and the blood sampling bottle 23 inside the shaking box 6 to rotate, so as to prevent the blood in the blood sampling bottle 23 from being coagulated. At the same time, the drive wheel 29 is driven to rotate through the output shaft of the drive motor 28. The drive wheel 29 is connected to the chain belt 30 to drive the drive wheel 31 to rotate. The drive wheel 31 drives the rotating shaft 26 to rotate, and then the rotating shaft 26 drives The cam 27 rotates. When the protruding part of the cam 27 rotates to the highest point, the cam 27 drives the rocking box 6 to move upward through the top block 32. The rocking box 6 also presses the spring 36 upward through the rectangular column 5, and at the same time extends the rod 37 is squeezed and compressed. When the convex part of the cam 27 rotates to the lowest point, the rectangular column 5 is pushed down by the return reaction of the spring 36, which in turn drives the shaking box 6 to move downwards, due to the convex part of the cam 27 Alternate rotation, so as to realize the up and down reciprocating movement of the shaking box 6, and then drive the blood in the blood sampling bottle 23 and the anticoagulant to shake up and down to mix uniformly; finally, the blood and the anticoagulant in the blood sampling bottle 23 are mixed in rotation At the same time, it can be shaken and mixed up and down, which speeds up the blood mixing and shaking speed, improves work efficiency, and reduces the burden on medical staff through mechanized operation, greatly reduces labor intensity, and also helps ensure the accuracy of subsequent test results Sex.
[0038] In this embodiment, the right output shaft 14 of the dual-axis stepping motor 9 can drive the shaft sleeve 10 and the cooling fan 11 to rotate, and the air volume generated by the rotation of the cooling fan 11 can in turn be used for the rotation of the dual-axis stepping motor 9 The heat emitted during the working process in the box 1 is dissipated.
[0039] In this embodiment, while the rotating plate 3 is rotating, it also moves in the annular ball groove 19 on the top of the bottom box 1 through the universal ball 18, which can play a supporting role and ensure the smooth rotation of the rotating plate 3 .
