The threaded rod 402 drives the tray 403 to slide in the empty slot of the sample rack 3, and puts the sealing cap 404 on the sample bottle 405 to prevent the peanut oil sample in the sample bottle 405 from being contaminated.

[0020] exist Figure 1 , Figures 3-5 In the middle, a sealing cap 404 is fitted inside the tray 403, and a sample bottle 405 is abutted below the sealing cap 404. The sample bottle 405 is abutted against the lower inner wall of the sample storage rack 3, and a placement rack 406 is sleeved on the outer side of the sample bottle 405. The placement rack 406 is connected to the inner wall of the sample storage rack 3 by screws.

[0021] The sealing cap 404 is placed inside the tray 403 through a T-shaped insertion hole. A baffle is abutted above the sealing cap 404. The baffle is rotated on the upper surface of the tray 403 by bolts to prevent the sealing cap 404 from falling off the tray 403. The placement rack 406 can be supported by plastic or iron sheet with U-shaped properties. The sample bottle 405 is inserted into the placement rack 406 for positioning. The bottom of the sample bottle 405 is supported by a rubber pad, which is embedded in the lower inner wall of the sample storage rack 3.

[0022] exist Figure 3 , Figure 4 and Figure 6 Inside the sealing cap 404, a liquid outlet pipe 407 and a silicone airbag 408 are connected through a rubber tube.

[0023] The liquid outlet tube 407 and the silicone air bag 408 can be directly removed for replacement or disposal.

A toothed plate 503 slides through the inner wall of the storage slot 502, and the end of the toothed plate 503 is engaged in the slot 501.

[0027] There are two sets of toothed plates 503, one set is Z-shaped and the other set is upright. After the sample holder 3 is inserted into the L-shaped plate 2, the slot 501 extends out from the sample holder 3 and is inserted into the slot 501 to prevent the sample holder 3 from falling out of the L-shaped plate 2. The sample holder 3 can be inserted into one set of L-shaped plates 2 on both sides of the detector body 1.

[0028] exist Figure 7 and Figure 8 In the middle, a gear 504 is meshed with one side of the toothed plate 503, and the gear 504 rotates through the front part of the inner wall of the storage groove 502.

[0029] A handle is installed at the front of the gear 504. By selecting the handle, the gear 504 is driven to rotate. When the gear 504 rotates, it drives the toothed plates 503 on both sides to be pulled out from the slots 501 and put into the sample rack 3, thereby releasing the restriction on the sample rack 3 and the L-shaped plate 2. The sample rack 3 can be pulled out from the L-shaped plate 2 or inserted into the L-shaped plate 2.

[0032] exist Figure 7 and Figure 8 In the middle, a spring 506 is sleeved on the outside of the T-shaped rod 505, and the spring 506 abuts against the toothed plate 503.

[0033] When the toothed plate 503 is pulled out of the slot 501, it compresses the spring 506. When the gear 504 is released, the spring 506 pushes the toothed plate 503 to reset and re-insert it into the slot 501.

[0034] In summary: When using this utility model, firstly, the rotating gear 504 inserts the sample holder 3 into the L-shaped plate 2, then the gear 504 is released for assembly. After turning on the detector body 1, it performs self-testing and calibration. Some peanut oil is added to the extract, and the mixture is vigorously shaken for 1 minute. After centrifugation and separation, the clear liquid is transferred to the sample bottle 405 as the sample liquid. The sample bottle 405 is placed in the placement rack 406 and the drive motor 401 is started. The bottle is then covered with the sealing cap 404. The detection card is placed at the outlet of the liquid outlet tube 407, and the silicone air bladder 408 is pressed to release the sample from the sample bottle 405. The droplet is placed into the sample application hole of the test card. The test card is then placed horizontally in a 37°C constant temperature incubator and reacted for 8-10 minutes. The test card is then inserted into the instrument's detection slot. The instrument automatically scans the light absorption signals of the T and C lines, calculates the peak area ratio, and automatically converts the toxin concentration using the system's built-in standard curve. The results are directly displayed on the touch screen. If the peanut oil in any sample bottle 405 fails to be detected due to a difference in the amount of droplet, the sample liquid in that sample bottle 405 will be tested again. Any content not described in detail in this instruction is prior art known to those skilled in the art.
