DETAILED DESCRIPTION

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] Reference Figure 1 The top of the base 1 is fixedly connected to the bracket 2, and the top of the bracket 2 is fixedly connected to the main control box 3. A pipetting mechanism 4 is arranged at the bottom of the main control box 3. The pipetting mechanism 4 has the functions of sucking sample liquid, temporarily storing sample liquid and spraying sample liquid. Its structure is similar to that of an injection syringe. A plurality of pipettes 5 are arranged at the bottom of the pipetting mechanism 4. The pipettes 5 are used to suck and spray sample liquid, so that the sample liquid can be transferred in time. A status display screen 6 is provided on one side of the main control box 3. A movable seat 7 is slidably connected to the base 1, and a top platform 8 is fixedly connected to one side of the movable seat 7. A bottom platform 9 is provided in the middle position of the base 1, and a positioning block 10 is provided on the top platform 8 and the base 1. The positioning block 10 is used to position the sample liquid storage box, so that it has a better effect in subsequent liquid transfer.

[0027] Further, refer to Figure 2 A driving motor 11 is fixedly connected to one side of the inner wall of the base 1, and the output shaft of the driving motor 11 is fixedly connected to the transmission shaft 12. A screw rod 13 is also rotatably connected inside the base 1, and the movable seat 7 is threadedly connected to the screw rod 13. A driving gear 14 is fixedly connected to one side of the transmission shaft 12, and a driven gear 15 meshing with the driving gear 14 is fixedly connected to one end of the screw rod 13. When the transmission shaft 12 rotates, the screw rod 13 is driven to rotate through the driving gear 14 and the driven gear 15, thereby changing the position of the movable seat 7.

[0028] Further, refer to Figure 2and Figure 3 A threaded rod 16 is also rotatably connected to the inside of the base 1, and a transmission mechanism 17 is provided between the threaded rod 16 and the transmission shaft 12. The transmission mechanism 17 is a belt drive, which can drive the threaded rod 16 to rotate when the transmission shaft 12 rotates. Sliding seats 18 are threadedly connected on both sides of the threaded rod 16, and the threads on both sides of the threaded rod 16 are relatively reverse threads. The top of the sliding seat 18 is rotatably connected to a support rod 19, and the top of the support rod 19 is rotatably connected to a rotating seat 20. The rotating seat 20 is fixedly connected to the bottom of the base 9. When the two groups of sliding seats 18 approach each other, the base 9 can be pushed upward by the support rod 19, thereby raising the base 9 to facilitate subsequent pipetting.

[0029] Furthermore, the two sets of sliding seats 18 are slidably connected to the bottom of the inner wall of the base 1, so that the sliding seats 18 are more stable when moving.

[0030] Furthermore, the status display screen 6 is rotatably connected to the main control box 3, and the inclination of the status display screen 6 can be adjusted for easy viewing.

[0031] The implementation principle of this embodiment is as follows: when in use, the storage box containing the sample liquid is placed on the top platform 8, so that the four corners of the storage box are aligned with the four sets of positioning blocks 10 respectively, thereby positioning the storage box, and then the pipette 5 is controlled to move downward by the pipetting mechanism 4 to extract the sample liquid inside the storage box, and then temporarily store it in the pipetting mechanism 4, and then the pipette 5 is controlled to move upward, and then the drive motor 11 is started, and the transmission shaft 12 is controlled to rotate by the output shaft of the drive motor 11, and the screw rod 13 is driven to rotate by the driving gear 14 and the driven gear 15. The movable seat 7 can move well under the action of the threaded connection between the screw rod 13, thereby moving the top platform 8 to one side. At the same time, the transmission shaft 12 also drives the threaded rod 16 to rotate through the transmission mechanism 17. The two sets of sliding seats 18 are threadedly connected to the threaded rod 16 through the sliding seat 18. The bottom platform 9 is lifted upward by the support rod 19 and the rotating seat 20, so that the bottom platform 9 can be raised to the height of the top platform 8. The pipette 5 is then controlled to move downward by the pipetting mechanism 4, and the sample liquid is sent to a new storage box for subsequent testing.
