[0038] Embodiment 2

[0039] The operation principle of the utility model:

[0040] When using this device, a blood tube containing an anticoagulant or other additives is placed inside the clamping block 35. Rotating the threaded rod 37 downwards pushes the push plate 33 downwards along both sides of the connecting frame 32. During this process, the push plate 33 presses against the rotating rod 34, causing the guide rod on the rotating rod 34 to slide along the inclined guide groove 331. This causes the rotating rod 34 to rotate on the connecting frame 32 via the rotating column 321, thereby driving the clamping blocks 35 on both sides of the connecting frame 32 to slide via the clamping members 36. By controlling the raising and lowering of the push plate 33 through the threaded rod 37, the clamping blocks 35 on both sides can be used to release and clamp the blood tube.

[0041] After multiple blood tubes are clamped and fixed on this device, the operator can select the device's operating time via the button module on the control panel 24. Upon receiving the relevant signal, the central processing unit transmits it to the motor 21. The motor 21 drives the first rotating shaft 222 and the transmission rod 223 to rotate together. The slider 224 on the transmission rod 223 slides back and forth on the sliding groove rod 235, causing the sliding groove rod 235, along with the rack 234, to move left and right on the first slide rail 236. The left and right movement of the rack 234 drives the meshing gear 233 to rotate back and forth, thereby indirectly driving the rotating plate 31 and the clamped blood tubes to rotate back and forth. (See attached image) Figs. 3 to 5 As shown, when the transmission rod 223 rotates to the rightmost position, the slide bar 235, along with the rack 234, moves to the rightmost position, at which point the rotating plate 31 is parallel to the base 11. When the transmission rod 223 rotates to the vertical position, the transmission rod 223 and the slide bar 235 coincide, at which point the rotating plate 31 rotates 90° and becomes perpendicular to the base 11. When the transmission rod 223 rotates to the leftmost position, the slide bar 235, along with the rack 234, moves to the leftmost position, at which point the rotating plate 31 rotates 180°. Subsequently, the transmission rod 223 continues to rotate, and the slide bar 235, along with the rack 234, moves to the rightmost position again, causing the rotating plate 31 to cyclically flip, thereby realizing the flipping and shaking of the blood test tube. After the device's working time ends, the central processing unit transmits an end signal to the alarm, and the alarm issues an end prompt.
