[0002] Colloidal gold is a commonly used labeling technique. It is a novel immunolabeling technique that uses colloidal gold as a tracer marker for antigen-antibody interactions. It has unique advantages and has been widely used in various biological research in recent years. Almost all immunoblotting techniques used in clinical practice use its labeling. It can also be used in flow cytometry, electron microscopy, immunology and molecular biology, and even biochips. A positioning device is required during the detection process.

[0003] Currently, Chinese utility model patent CN222167045U discloses a colloidal gold detection and positioning device, which relates to the field of colloidal gold detection. Due to the limitations of the main body of the device, the included angle between the two sets of colloidal gold detection strips is limited, and the thickness of people's fingers is different. Therefore, it is not suitable for different people and has poor applicability. At the same time, the disassembly and assembly of the colloidal gold detection strips are not convenient enough, which has certain defects in use. Utility Model Content

[0031] A guide rod 302 is fixedly connected to the inner wall of the fixed base 1. The outer side of the guide rod 302 is slidably connected to the inner wall of the positioning block 301. Through the cooperation of the positioning block 301 and the guide rod 302, the clamping plate 3 can move stably.

[0032] refer to Figure 1 and Figure 2 The drive mechanism includes a connecting shaft 5 that rotates on the inner wall of the fixed base 1. A knob 6 is fixedly connected to the top of the connecting shaft 5, and a driving wheel 7 is fixedly connected to the bottom of the connecting shaft 5.

[0034] Brief description of the usage process: Turn the knob 6 to make the connecting shaft 5 drive the driving wheel 7 to rotate. When the driving wheel 7 rotates, it can drive the driven wheel 8 to rotate, which in turn drives the lead screw 2 to rotate. When the lead screw 2 rotates, it can make the two sets of clamping plates 3 move the colloidal gold detection strips 4 closer or further apart, and reduce the angle distance between the two sets of colloidal gold detection strips 4. This is suitable for different personnel. Then, prick the person's hand to let the blood flow into the sample application hole of the colloidal gold detection strip 4.

[0039] Brief description of the usage process: When it is necessary to disassemble and replace the colloidal gold detection strip 4, move the limiting plate 11 to make the connecting plate 10 drive the slider 13 to move, and compress the spring 12, thereby releasing the restriction on the colloidal gold detection strip 4. Then, place the new colloidal gold detection strip 4 on the top of the positioning plate 9 and attach it to one side of the clamping plate 3. At this time, release the limiting plate 11. The rebound force of the spring 12 can make the limiting plate 11 automatically reset and fix the colloidal gold detection strip 4. The operation is convenient and does not require disassembly of the device.
