A card feeding port 201 is opened on the left side of the front of the analyzer body 1. The placement frame 202 is arranged inside the card feeding port 201. The slide bar 203 is symmetrically fixedly connected to the bottom surface of the placement frame 202. The rack 204 is symmetrically fixedly connected to the bottom surface of the placement frame 202. Two racks 204 are arranged on both sides of the two slide bars 203. The gear 205 is arranged below the rack 204, and the rack 204 and the gear 205 are meshed.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the two ends of the connecting shaft 206 are fixedly connected to the inside of the two gears 205 respectively, the motor 207 is fixedly connected to the inside of the analyzer body 1, and the left end of the connecting shaft 206 is connected to the output end of the motor 207.

[0027] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the reagent card body 6 is arranged inside the placement frame 202, and a groove matching with the slide bar 203 is opened inside the card inlet 201;

[0028] The staff can directly place the reagent card body 6 inside the placement frame 202 to avoid the reagent card body 6 being damaged by plugging and unplugging operations.

[0029] According to the above working process, it can be known that: through the card feeding mechanism 2, the staff can directly place the reagent card body 6 inside the placement frame 202, and automatically transport it into the analyzer body 1 for testing, eliminating the plugging and unplugging operation of the reagent card body 6, avoiding damage to the reagent card body 6, ensuring the accuracy of the test data, and reducing the labor intensity of the staff.

[0030] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the protection mechanism 4 is composed of a fixed seat 401, a rotating column 402, a connecting bar 403, a torsion spring 404, a protective cover 405, a handle 406 and a positioning assembly 408. The fixed seat 401 is symmetrically fixedly connected to the top of the analyzer body 1, the rotating column 402 is fixedly connected to the middle of the two fixed seats 401, the connecting bar 403 is rotatably connected to the outside of the rotating column 402, the torsion spring 404 is fixedly connected between the connecting bar 403 and the opposite surface of the fixed seat 401, the protective cover 405 is fixedly connected to one side of the connecting bar 403, and the positioning assembly 408 is symmetrically arranged on both sides of the front end of the protective cover 405;

[0031] Due to the elastic effect of the torsion spring 404 , when the positioning assembly 408 fails to position the protective cover 405 , the protective cover 405 is driven to be in an open state, which does not affect the use of the display screen 3 .

[0032] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the positioning assembly 408 is composed of a fixed plate 4081, a positioning rod 4082, a movable plate 4083, a spring 4084 and a slider 4085. The fixed plate 4081 is fixedly connected to the top of the analyzer body 1, the positioning rod 4082 is slidably connected to both sides of the fixed plate 4081, the movable plate 4083 is fixedly connected to one end of the positioning rod 4082 away from the protective cover 405, the slider 4085 is fixedly connected to the bottom of the movable plate 4083, and the top of the movable plate 4083 is installed on the push block;

[0033] The moving plate 4083 is moved by pushing the push block, and then the slider 4085 is slidably connected to the top surface of the analyzer body 1 to ensure the horizontality and stability of the movement of the positioning rod 4082.

[0034] Further as Figure 3 , Figure 4 and Figure 5 As shown, it is worth to explain in detail that the spring 4084 is fixedly connected between the opposite surfaces of the movable plate 4083 and the fixed plate 4081, and is sleeved on the outside of the positioning rod 4082, the handle 406 is fixedly connected to the upper front side of the protective cover 405, and the left and right sides of the protective cover 405 are symmetrically provided with positioning grooves 407, and the positioning rod 4082 is adapted to the shape of the positioning groove 407;

[0035] The spring 4084 is used to elastically reset the positioning rod 4082 so that the positioning rod 4082 is inserted into the positioning groove 407 to fix the position of the protective cover 405, thereby ensuring that the protective cover 405 stably protects the display screen 3 below.

[0036] This solution has the following working process: when in use, the motor 207 is controlled to rotate clockwise, and the gear 205 is driven to rotate through the connecting shaft 206, and the rack 204 is meshed with the gear 205 to drive the upper placement frame 202 to move out of the interior of the card entry port 201, until the placement slot above the placement frame 202 is completely moved out of the card entry port 201, and then the reagent card body 6 is placed in the placement slot, and the motor 207 is controlled to reverse, drive the placement frame 202 and the reagent card body 6 to be transported back to the interior of the analyzer body 1, and the reagent card body 6 is tested and analyzed, thereby improving the full automation of the instrument; then the moving plate 4083 is pushed outward, driving the positioning rod 4082 to disengage from the interior of the positioning slot 407, and releasing the connection with the protective cover 405. Under the elastic action of the torsion spring 404, the protective cover 405 is automatically driven to open without affecting the use of the display screen 3.

[0037] In summary: through the card feeding mechanism 2, the staff can directly place the reagent card body 6 inside the placement frame 202, and automatically transport it into the analyzer body 1 for testing, eliminating the plugging and unplugging operation of the reagent card body 6, avoiding damage to the reagent card body 6, ensuring the accuracy of the test data, and reducing the labor intensity of the staff; through the protective mechanism 4, the display screen 3 can be protected when the instrument is not in use to avoid damage to the display screen 3 by external objects, thereby improving the safety performance of the instrument.
