Triangular piles 602 are installed at the four corners of the bottom of the upper support plate 601, and buffer rings 603 are arranged in an equidistant array in the middle of the upper support plate 601. Two groups of support frames 6 are arranged up and down inside the transparent box body 102. The inner surface structure of the buffer ring 603 matches the bottom surface structure of the extraction collection tube 5, and the extraction collection tube 5 vertically penetrates through the middle of the support frame 6. Moreover, the surface diameter size of the extraction collection tube 5 matches the inner diameter size of the buffer ring 603. Among them, the middle of the extraction collection tube 5 vertically penetrates through the upper support plate 601 where the buffer ring 603 is installed, and the bottom of the extraction collection tube 5 is vertically inserted into the inside of the buffer pile 703. At the same time, the lower support plate 701 and the upper support plate 601 respectively provided with the triangular frame 702 and the triangular pile 602 are cooperated, so that the extraction collection tube 5 can be stably inserted inside the extraction box 1.
[0028] As Figures 1 to 5 shown, the extraction tank 1 includes a lower base 101, a transparent box body 102, an upper cover 103, fastening screws 104 and a connecting valve 105.

With the use of the structures of the support frame 6 and the support base 7, the stability of the extraction and collection tube 5 is ensured;
[0031] Subsequently, the upper cover 103 is buckled on the top of the transparent box body 102, and then the fastening screw 104 is vertically threadedly installed on the sides of the upper cover 103 and the lower base 101 in sequence. By screwing the fastening screw 104, the lower base 101 and the upper cover 103 tightly clamp the transparent box body 102 in the middle. After that, it can be connected to the connection valve 105 on one side of the transparent box body 102 through a pipeline, and a vacuum pump is connected thereto;
