The zero mark of the scale 705 is flush with the top of the adjusting ring 701. During sampling, the adjusting ring 701 can be moved out of the adjusting groove 702 under the action of the adjusting plate 703 according to the sampling position requirements of the sampling solution. The vertical value of the exposed scale 705 plus the distance from the sampling tube 4 to the bottom of the adjusting ring 701 equals the sampling position. At this time, the sampling device is placed into the food solution and the adjusting ring 701 is brought into contact with the bottom of the container. This achieves the purpose of sampling the food solution at the required position, improving the practicality of this rapid sampling device for food testing.

[0029] Furthermore, the outer ring of the adjusting ring 701 is fixedly connected with four elastic retaining rings 706.
