At this time, the support ring 13 fixedly connected to the inner wall of the inner sampling tube groove 12 can install the support rod 2, and the extension rod 24 is installed on the top of the support rod 2, so that the bottom of the support rod 2 can slide down to a position offset from the inner wall of the inner sampling tube groove 12, so that the upper sealing block 21 and the lower sealing block 22 can be at the lower end of the outer sampling tube 1 The chemical liquid to be sampled can effectively enter the inner sampling tube groove 12. At this time, the extension rod 24 can be pulled upward to drive the upper sealing block 21 and the lower sealing block 22 to move upward, so that the top of the upper sealing block 21 can be inserted into the inner wall of the inner sampling tube groove 12. After the upper sealing block 21 is supported on the inner wall of the inner sampling tube groove 12, the support rod 2 and the extension rod 24 can be rotated to make the upper sealing block 21 rotate synchronously with it. During the rotation, the bottom of the upper sealing block 21 and the bottom of the inner wall of the inner sampling tube groove 12 can be connected and sealed by opening a matching threaded wall. After the upper sealing block 21 and the inner sampling tube groove 12 are closed, the bottom of the device can be separated from the chemical liquid.

[0021] The inner sampling tube groove 12 and the support ring 13 are connected by a frame plate 131, and a connector 241 is fixedly connected to the connection between the extension rod 24 and the support rod 2. A threaded groove 242 matching the connector 241 is provided on the top of the support rod 2; the frame plate 131 between the inner sampling tube groove 12 and the support ring 13 is used to fix the support ring 13 at the center of the inner wall of the inner sampling tube groove 12, so that the support rod 2 can pull the upper sealing block 21 upward to connect and close the inner sampling tube groove 12, and when the upper sealing block 21 is threadedly connected to the bottom of the inner sampling tube groove 12, the top of the support rod 2 can be threadedly connected to the inner wall of the support ring 13, so that after the sealing plate 33 is docked to the support ring 13, the sliding hole 25 is ensured to be sealed to prevent the sampled chemical liquid from leaking.

[0022] The top of the extension rod 24 is fixedly connected to a connecting head 241, and the top of the connecting rod 26 is fixedly connected to an adjusting plate 262; the connecting head 241 fixedly connected to the top of the extension rod 24 is used to facilitate pulling the extension rod 24 and the support rod 2, and the adjusting plate 262 is used to facilitate rotating the connecting rod 26 to adjust its connection with the mounting groove 232, and at the same time facilitate pulling it out of the sliding hole 25.

[0025] The working principle and use process of the present invention are as follows: the upper sealing block 21 and the lower sealing block 22 are supported by the support rod 2 and the extension rod 24. The upper sealing block 21 and the lower sealing block 22 can be located below the outer sampling tube 1, so that the chemical liquid to be sampled can effectively enter the inner sampling tube groove 12. The outer wall of the inner sampling tube groove 12 is wrapped by the support groove 11 opened by the outer sampling tube 1, so that the outer wall of the inner sampling tube groove 12 is prevented from being contaminated by the chemical liquid. After part of the chemical liquid enters the inner sampling tube groove 12, the extension rod 24 and the support rod 2 can be pulled upward to allow the upper sealing block 21 to enter the inner wall of the inner sampling tube groove 12, and the extension rod 24 and the support rod 2 are rotated to allow the upper sealing block 2 1 is threadedly connected to the bottom of the inner sampling tube groove 12 to seal its bottom. At the same time, the top of the support rod 2 can be threadedly connected to the inner wall of the support ring 13, so that the sealing cover 3 is installed at the top position of the inner sampling tube groove 12, so that the sealing plate 33 fixedly connected to the bottom end of the docking block 32 can be installed to the top of the inner sampling tube groove 12. The sealing plate 33 is sealed on the support ring 13 and the sliding hole 25 opened on the support rod 2 is closed, so that after the inner sampling tube groove 12 slides out, it can ensure its sealing of the chemical liquid. At the same time, when the chemical liquid is taken, the residual chemical liquid outside the device is reduced, which is not conducive to the safe taking and placing of the chemical liquid by the staff, and the residual chemical liquid on the sampling device needs to be processed again.
