[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1: Comprehensive Food Safety Analyzer, see [link / reference] Figures 1 to 4 The device includes a body 1 and a touch screen 11, buttons 12, a first detection unit 15 and a second detection unit 14 mounted on the body 1. The first detection unit 15 is mounted on the rear end of the body 1, and the second detection unit 14 is mounted on the top end of the body 1. A cover 2 is rotatably connected to one side of the top of the body 1 via a pivot. A cover frame 13 is mounted on the body 1 outside the first detection unit 15, and the top of the cover frame 13 is open.

[0022] The shielding frame 13 is provided with a shielding mechanism 3. The shielding mechanism 3 includes damping shafts 31 installed at both ends of the shielding frame 13. Each of the two damping shafts 31 is connected to a sleeve 32. Each of the two sleeves 32 is slidably connected to an adjusting rod 34. A shielding plate 35 is fixedly connected between the two adjusting rods 34. Both the sleeves 32 and the adjusting rods 34 are rectangular. Each of the outer ends of the two sleeves 32 is penetrated by a bolt 33. The bolt 33 is threaded into the sleeve 32 and contacts the surface of the adjusting rod 34.

[0023] During operation, when carrying the machine body 1, the shield 35 is placed horizontally by rotating the sleeve 32. Then, the shield 35 is pulled to overlap the top of the shield frame 13. The bolt 33 is then rotated to contact the adjusting rod 34, limiting the adjusting rod 34 and positioning the shield 35 at the top opening of the shield frame 13. This shields the first detection unit 15. The shield is then rotated to cover the second detection unit 14. This protects both the first and second detection units 15 during the carrying process of the machine body 1, preventing dust from accumulating on the detection units and affecting the accuracy of the detection results or causing damage. When using the machine body 1... Loosen bolt 33 and rotate shield 35 away from shield frame 13 via damping shaft 31. Then continue to rotate shield 35 to tilt it downwards, so that sleeve 32 and adjusting rod 34 can support the rear end of machine body 1. During testing, there is no need for personnel to hold machine body 1, which is more convenient. Loosening bolt 33 can adjust the length of the connection between sleeve 32 and adjusting rod 34. When the appropriate length is adjusted, tighten bolt 33 to limit the adjusting rod 34, so that the angle of support of sleeve 32 and adjusting rod 34 on machine body 1 can be adjusted, which makes it easier for testing personnel to observe the test results on touch screen 11 from the best viewing angle.

[0024] For details, see Figure 3The first detection unit 15 includes a colloidal gold module and a dry chemical detection module. The colloidal gold module, together with a matching colloidal gold detection card, detects pesticide, veterinary drug, and antibiotic residues. The dry chemical detection module, together with a matching detection card, detects organophosphate, carbamate pesticide residues, and illegal additives. The second detection unit 14 includes an ATP fluorescence detection module. The ATP fluorescence detection module, together with a matching swab, detects solid surfaces and water samples for organic residues and microbial contamination. During detection, the detection card is inserted into the shielding frame 13 and corresponds to the first detection unit 15. Then, the colloidal gold module and the dry chemical detection module detect pesticide, veterinary drug, and antibiotic residues, organophosphate, carbamate pesticide residues, and illegal additives. When detecting ATP, firstly, the ATP swab is removed and allowed to warm to room temperature. Remove the test tube, use a cotton swab to gently wipe an area of ​​approximately 100 cm² of the surface of the object to be tested, replace the test tube, remove the clip, push the sealing stopper connected to the test tube into the rubber cap and push out the silicone ball at the orifice, tilt the swab, squeeze the reagent into the bottom of the test tube, shake it a few times, open the shield, align the test tube with the second detection unit 14, squeeze in the reagent, and then use the ATP fluorescence detection module to detect the residual amount of bacteria or other microorganisms and food residues in the sample, thereby determining the cleanliness of the sample. After the test is completed, the detected data is transmitted to the system platform via built-in Wi-Fi, and the test results are printed via built-in Bluetooth. Furthermore, the colloidal gold detection, ATP fluorescence detection, and dry chemical detection modules are integrated together, effectively dividing the three detection methods for different detection requirements, making the equipment more simple and portable, and improving detection efficiency.

[0025] Further, see Figure 4 A spring 36 is installed at the bottom of the inner cavity of the sleeve 32. The other end of the spring 36 is connected to the adjusting rod 34. The tension of the spring 36 is less than the frictional force between the bolt 33 and the adjusting rod 34. This is to prevent the tension of the spring 36 from pulling the adjusting rod 34 to retract after the adjusting rod 34 is stretched, thus affecting the support of the machine body 1. One end of the baffle plate 35 is equipped with an elastic sealing gasket 37, and the size of the baffle plate 35 is adapted to the size of the opening of the baffle frame 13. Through the setting of the spring 36, when the adjusting rod 34 is stretched, the spring 36 will be stretched. 6 is also stretched. When the adjusting rod 34 needs to be reset, simply loosen the bolt 33. The tension of the spring 36 will automatically pull the adjusting rod 34 to reset. When the baffle plate 35 is at the top of the baffle frame 13, the spring 36 is in a stretched state. Thus, the tension of the spring 36 increases the pressure between the baffle plate 35 and the baffle frame 13. This, in conjunction with the sealing gasket 37, increases the friction between the baffle plate 35 and the baffle frame 13, thereby improving the stability and sealing of the baffle plate 35 on the baffle frame 13, and further improving the protection effect on the first detection unit 15.
