When in use, the cover 2 is removed from the surface of the hollow threaded member 51, the internal thread on the left side of the extractor 3 is threadedly connected with the hollow threaded member 51, and the piston member 61 is pulled. The piston member 61 moves to the right so that a negative pressure is formed on the inner wall of the extractor 3, so that the long rod 65 stretches the spring 2 64 to move to the right. At this time, a negative pressure is formed on the right side of the hollow threaded member 51, so that the blocking block 54 moves to the right to stretch the spring 1 53. The liquid food in the tank body 1 enters the inner wall of the extractor 3 through the gap between the hollow threaded member 51 and the blocking block 54, the open disc block 63, and the gap between the hollow disc block 62 and the long rod 65, and is extracted at the upper and lower five sampling holes 4 respectively, so as to avoid inaccurate data and facilitate sampling.
