[0030] One end of the rotating member 32 is a front convexity 321, and the other end of the rotating member 32 is a rear convexity 322.

[0033] During specific use, the medical staff puts the blood collection tube filled with blood into the blood collection tube slot 111 of the mixing tank 11. As the blood collection tube is inserted into the blood collection tube slot 111, when the bottom of the blood collection tube touches the anti-sliding block 131, the anti-sliding block 131 will be squeezed along the inclined surface of the anti-sliding block 131, so that the anti-sliding block 131 compresses the pressure spring 132 and slides into the anti-slip groove 122. Under the elastic force of the pressure spring 132, the friction between the anti-sliding block 131 and the blood collection tube is increased, thereby fixing the blood collection tube to prevent it from falling off.

[0034] After the blood collection tube is fixed, the switch is turned on, the motor 311 is started, and the driving shaft 31 is driven to rotate. The driving bevel gear 312 on the driving shaft 31 drives the bevel gear 324 of the rotating member 32 to rotate, and then the meshing plate 323 of the rotating member 32 rotates, and the meshing plate 323 pushes the meshing column 115 of the mixing tank 11, and the mixing tank 11 is rotated.

Under the guidance of the sliding groove 114, the rotating member 32 drives the mixing tank 11 to reciprocate, and also causes the mixing tank 11 to reciprocate along the axial direction of the bottom rotating shaft 113. The bottom rotating shaft 113 at the bottom of the mixing tank 11 slides up and down in the rotating shaft sliding sleeve 22 of the rotating bin 2.

[0035] During the rotation of the driving shaft 31, the driving gear 313 on the driving shaft 31 drives the connecting gear 33 to rotate, the connecting gear 33 drives the gear ring 23 to rotate, the gear ring 23 drives the rotating chamber 2 to rotate, and the mixing tank 11 rotates under the drive of the rotating chamber 2, and then the blood collection tube will not only rotate with the self-rotation of the mixing tank 11, but also move back and forth along the axial direction of the bottom rotating shaft 113 with the rotating mixing tank 11, oscillating the blood inside the blood collection tube. At the same time, the mixing tank 11 will also rotate with the rotating chamber 2, thereby achieving the technical effect of fully mixing the blood inside the blood collection tube. After sufficient mixing, turn off the switch, the medical staff draws out the blood collection tube and replaces it with another batch of blood collection tubes filled with blood for mixing. The device is equipped with a battery, so that the device can be used anytime and anywhere without relying on a power socket. The heat dissipation slot on the back panel 43 prevents the device from overheating and prevents the temperature from affecting the results of the blood test.
