[0049] At least two swing angle shafts 106 are arranged, one end of each swing angle shaft 106 is mounted on the corresponding tilt mounting seat 105, and the other end is mounted on the surface of the spin reaction unit;

[0055] Specifically, the spin reaction unit includes but is not limited to the magnetic bead centrifugal reaction device in the prior art.

[0056] Further, the other end of each connecting rod 1010 is hingedly connected with the slide post 1011; and each gear 107 is engaged with the corresponding rack 109.

[0057] A driving unit 2 is configured to drive the rotation of the tilt angle unit 1; and the driving end of the driving unit 2 is connected with the rotating end of the tilt angle unit 1.

[0058] The driving unit 2 is installed on the base of the purification device.

[0059] Specifically, the driving unit 2 includes:

[0060] A servo electric actuator 201 is fixedly installed at the lower end of the cylinder of the purification device;

[0061] A telescopic plate 202 is located below the cylinder of the purification device; and the telescopic end of the servo electric actuator 201 is fixedly connected with the telescopic plate 202.

[0062] At least one telescopic post 203 is installed at one end of the telescopic plate 202.

[0063] A spiral telescopic hollow post 204 is located in the purification device; and at least one spiral block 205 is arranged on the outer surface of the spiral telescopic hollow post 204.

[0064] A rotating hollow post 206 is located outside the spiral telescopic hollow post 204; and a spiral groove 207 is arranged at the lower end of the inner side of the rotating hollow post 206.

[0066] Further, the other end of the telescopic post 203 is installed on the outer surface of the spiral telescopic hollow post 204 through a bearing seat 208, so that the rotation of the spiral telescopic hollow post 204 and the telescopic movement of the telescopic post 203 do not affect each other.
