A guide motor 9 is fixedly connected to the guide frame 8, a display 3 is fixedly connected to the console 2, a circuit board is provided in the box body 1 at a position behind the display 3, an inlet 4 is opened on the console 2 at a position below the display 3, a gasket frame 14 is movably installed below the inlet 4, a gasket motor 15 is fixed to the side of the gasket frame 14, a heat preservation cover 6 is fixedly connected to the turntable box 5, an electric heating plate is provided in the turntable box 5 at a position below the turntable frame 10, and a turntable motor 16 is fixed to the turntable box 5;

[0026] The limiting component is a swing arm positioning component 12, which includes a swing arm frame 1201, a first swing rod 1202, a second swing rod 1203, a first swing arm 1206 and a second swing arm 1207. The swing arm frame 1201 is fixed at the lower position of the turntable box 5, the first swing rod 1202 and the second swing rod 1203 are rotatably connected in the swing arm frame 1201, and the second swing rod 1203 is located at the side of the first swing rod 1202. The first swing arm 1206 is fixed at the lower position of the turntable box 5, and the first swing rod 1202 and the second swing rod 1203 are rotatably connected in the swing arm frame 1201. The second swing rod 1203 is located at the side of the first swing rod 1202. It is fixedly connected to the No. 1 rocker arm 1202, and the No. 2 rocker arm 1207 is fixedly connected to the No. 2 rocker arm 1203. The rocker arm positioning assembly 12 also includes a rocker arm motor 1204 and a rocker arm gear 1205.

The rocker arm gear 1205 is fixedly connected to the No. 1 rocker arm 1202 and the No. 2 rocker arm 1203.

[0027] The working principle of the present invention is as follows: after the reagent is injected into the reagent card, the reagent card enters the box body 1 from the inlet 4 and falls into the card slot of the turntable frame 10 at the lower position. The turntable frame 10 moves to the side under the rotation of the turntable motor 16. An electric heating plate is provided at the lower position of the turntable frame 10. The electric heating plate is powered on to heat the reagent card, so as to heat the reagent card. After the turntable frame 10 moves the reagent card to the lower position of the limiting plate 11, it stops rotating and starts the swing arm motor 1204 to rotate the No. 2 swing rod 1203. The No. 2 swing rod 1203 rotates the No. 1 swing rod 1202 through the swing arm gear 1205, so that the No. 1 swing rod 1202 rotates, and the No. 1 swing arm 1206 and the No. 2 swing arm 1207 approach each other. According to the width of the reagent card, the two sides of the reagent card are limited, and the limiting plate 11 squeezes the reagent card downward to limit the reagent card, so that the reagent card can be easily limited from the upper and lower, left and right positions, so that the reagent card is easy to position and heat. The fluorescence detector 7 moves sideways to detect the reagent card, so that the test result is more accurate, and the swing arm motor 1204 is easy to adjust according to the width of the reagent card, which improves the applicability of the reagent card. After the test is completed, the turntable frame 10 moves again to move the reagent card to the initial position. The reagent card is supported by the turntable box 5 and the gasket frame 14. At this time, the gasket motor 15 is started to move the gasket frame 14 sideways, so that the reagent card falls downward, which is convenient for moving out from the exit position set on the console 2.

[0028] Example 2:

[0029] Different from Example 1, Figure 6 and Figure 7 As shown, the limiting component is a wheel positioning component 13, and the wheel positioning component 13 includes a wheel frame 1301, a number one rotating rod 1302, a number two rotating rod 1304 and an eccentric rotating wheel 1305. The wheel frame 1301 is fixed at the lower position of the turntable box 5, the number one rotating rod 1302 and the number two rotating rod 1304 are rotatably installed in the wheel frame 1301, and the eccentric rotating wheel 1305 is fixedly connected to the number two rotating rod 1304. The wheel positioning component 13 also includes a wheel motor 1303 and a rotating gear 1306. The wheel motor 1303 is fixed at a side position of the wheel frame 1301, and the output shaft of the wheel motor 1303 is fixedly connected to the number one rotating rod 1302, and the rotating gear 1306 is fixedly connected to the number one rotating rod 1302 and the number two rotating rod 1304.

[0030] The working principle of the present invention is as follows: the reagent card enters from the inlet 4 and falls into the card slot on the lower turntable frame 10. The turntable motor 16 rotates the turntable frame 10, so that the reagent card is easy to move to the position below the limiting piece 11. The limiting piece 11 is a spring structure, which is convenient for limiting the upper and lower positions of the reagent card. The turntable box 5 is provided with an electric heating piece at the lower position of the turntable frame 10 to heat the reagent card. The wheel motor 1303 is started to rotate the No. 1 rotating rod 1302. The No. 1 rotating rod 1302 transmits the No. 2 rotating rod 1304 through the rotating gear 1306, so that the No. 2 rotating rod 1304 rotates synchronously. The eccentric wheel 1305 on the second rotating rod 1304 is eccentrically installed. As the second rotating rod 1304 rotates, the eccentric wheel 1305 is easily lifted from the lower position of the turntable box 5 into the turntable box 5. The two side positions of the eccentric wheel 1305 clamp the two side positions of the reagent card, so that the two side positions of the reagent card are limited. At this time, the guide motor 9 is started to rotate the movable guide frame 8 and push the fluorescence detector 7 sideways, so that the fluorescence detector 7 moves to the upper position of the reagent card to detect the reagent card. By limiting the position of the reagent card and heating the temperature, the detection result of the reagent card is more accurate.
