[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. In this utility model, the anti-slip layer is fixedly connected to several circular slots arranged in a ring array on the lower wall of the chuck in the snap-fit assembly. This design effectively solves the problem that the sample placement area of traditional ELISA readers is smooth, and the sample is prone to displacement due to vibration or improper operation. During instrument operation, the anti-slip layer provides strong friction to ensure stable sample placement and avoid the detection optical path from being unable to accurately align with the sample due to sample displacement, which greatly improves the reliability of the detection results. At the same time, several slots on the outer surface of the chuck are precisely snapped into several snap-fit blocks arranged in a ring array on the inner wall of the turntable, with their positions and dimensions corresponding one-to-one.

The operator only needs to pull the ergonomically designed handle to move the fixing plate along the movable shaft, easily overcoming the tension of the tension spring. When it is necessary to lock the sample position, the handle is released, and the elastic restoring force of the tension spring drives the fixing plate to accurately engage with the front tooth groove of the gear block, thereby restricting the rotation of the rotating rod and fixing the sample position. This process is simple and efficient, avoiding the tedious steps of multiple manual fine adjustments in the traditional method. Moreover, the resistance layer fixedly connected to the rear side of the fixing plate increases the friction between it and the tooth groove of the gear block, preventing the fixing plate from accidentally coming off due to external force vibration and other factors, ensuring the stability and reliability of sample positioning, ensuring the accuracy of sample position during long-term detection by the ELISA reader, and effectively solving the problem of insufficient fixing force of traditional fixing devices.

Rotating the rotating rod 42, which is located at the center of the upper right side of the base 1, its lower end is movably connected to the base 1 via a bearing located on the right side of the microplate reader body 2 near the base 1. The gear block 43, fixedly connected to the middle of the outer surface of the rotating rod 42, rotates with the rotating rod 42, driving the turntable 41 and the clamping assembly 45 to rotate, thereby achieving flexible adjustment of the sample position. When it is necessary to fix the sample position... Pulling the handle 51 of the fixing device 5 moves the fixing plate 54, which is sleeved on the outer surface of the movable shaft 56 at the right end of the connecting block 52. The resistance layer 55 on the rear side of the fixing plate 54 enhances the fixing effect. The other end of the tension spring 53 connected to the front end of the fixing plate 54 is fixed to the upper end of the base 1. After releasing the handle 51, under the action of the tension spring 53, the fixing plate 54 is embedded in the front tooth groove of the gear block 43, thereby fixing the position of the rotating rod 42 and achieving precise positioning of the sample. On the one hand, the snap-fit design of the snap-fit component 45 and the turntable 41, and The anti-slip layer 454 inside the circular groove 452 ensures the stability and accuracy of the sample during placement and rotation, preventing sample displacement from affecting the test results. On the other hand, the cooperation between the rotating rod 42, gear block 43, and fixing device 5 enables convenient adjustment and precise locking of the sample position, improving operational efficiency. Meanwhile, the design of the transparent cover 3 and the door panel 6 facilitates the operator's observation and operation of the inside of the ELISA reader body 2 and the base 1, and the fixing device 5 is located directly in front of the door panel 6, further optimizing the convenience of operation.
[0028] In this embodiment, the fixing device 5 includes a connecting block 52. A movable shaft 56 is inserted and installed at the right end of the connecting block 52. A fixing pressure plate 54 is sleeved on the outer surface of the movable shaft 56. A resistance layer 55 is fixedly connected to the rear side of the fixing pressure plate 54.

Rotating the rotating rod 42, the rotating rod 42 is located at the center of the upper right part of the base 1. Its lower end is movably connected to the upper right part of the base 1 through a bearing and is located inside the ELISA reader body 2. The gear block 43 fixedly connected to the middle of the outer surface of the rotating rod 42 rotates accordingly. When it is necessary to fix the rotating rod 42, the gear block 43 is fixedly connected to the middle of the outer surface of the rotating rod 42. When in position 2, pull the handle 51 in the fixing device 5. The fixing plate 54 is sleeved on the outer surface of the movable shaft 56 that is inserted and installed on the right end of the connecting block 52. The resistance layer 55 fixedly connected to the rear side of the fixing plate 54 can increase the fixing effect. The other end of the tension spring 53 fixedly connected to the front end of the fixing plate 54 is fixedly connected to the upper end of the base 1. When the handle 51 is released, the fixing plate 54 is located in the front tooth groove of the gear block 43 under the action of the tension spring 53, thereby fixing the position of the rotating rod 42 and realizing the positioning of the sample. During the operation, if it is necessary to observe the inside of the ELISA reader body 2, the transparent cover 3 set at the front of the upper end of the ELISA reader body 2 can be opened.
