6. The diagnostic analyzer as claimed in claim 5, wherein the elastic member is a V-shaped spring, one arm of the V-shaped spring is connected to the hook fastening seat, the other arm of the V-shaped spring is connected to the base, and the opening of the V-shaped spring faces the direction of the hook body.
7. The diagnostic analyzer as set forth in claim 6, wherein the bottom surface of the base has a groove, a through hole is formed in the groove and penetrates obliquely through the top surface of the base, one arm of the V-shaped spring is connected to the hook holder in an abutting manner, the other arm of the V-shaped spring passes through the through hole from the groove and is exposed from the top surface of the base, the exposed end of the V-shaped spring has a bent portion bent inward, and the width of the groove is adapted to the width of the arm in the groove.
8. The diagnostic analyzer as claimed in any one of claims 1 to 7, wherein the card ejecting mechanism comprises a card ejecting pushing plate, a guiding mechanism and a resetting mechanism, the card feeding mechanism drives the reagent card to push the card ejecting pushing plate to eject the reagent card on the card ejecting position along the guiding mechanism in a reciprocating motion in a horizontal direction to realize card ejection, and the resetting mechanism drives the card ejecting pushing plate to reset after card ejection.
9. The diagnostic analyzer as claimed in claim 8, wherein the card ejecting mechanism further comprises a support, the card ejecting pushing plate is connected to one side of the support, the guiding mechanism comprises a guiding shaft, and two guiding shaft support units, two ends of the guiding shaft are respectively connected to the two guiding shaft support units, the support is disposed on the guiding shaft in a penetrating manner, and the card feeding mechanism drives the reagent card to push the support to reciprocate along the guiding shaft in a horizontal direction.
10. The diagnostic analyzer of claim 9, wherein the reset mechanism comprises an elastic member, the elastic member is disposed on the guide shaft, one end of the elastic member abuts against the support unit of the guide shaft on the side of the ejector plate, and the other end of the elastic member abuts against the side of the support on the side of the ejector plate.
