[0023] In this embodiment, the suction tube 2 is fixed at the end of the main body 1 and is connected to the liquid storage chamber 3, the operating main rod 5 is adapted to the liquid storage chamber 3, the first rotating member 6 is fixedly connected to the outer end of the operating main rod 5, and the operating main rod 5 and the operating support rod 7 can be easily controlled by the first rotating member 6 and the second rotating member 8; the operating support rod 7 is adapted to the threaded hole 16, one end of the operating support rod 7 passes through the threaded hole 16 and is fixedly connected to the fixing member 9, and the other end of the operating support rod 7 extends out of the operating main rod 5 and passes through the first rotating member 6 and is fixedly connected to the second rotating member 8. By operating the main rod 5 and the operating support rod 7 in conjunction with the fixing member 9 and the sealing ring 10 and in combination with corresponding operations, titanium tetrachloride will not come into contact with the air after entering the sampler, which can avoid reaction with the air and reduce safety hazards; the sealing ring 10 is fixedly installed on the fixing member 9 and Corresponding to the sealing groove 4, the sealing ring 10 is adapted to the sealing groove 4, and the suction tube 2 and the liquid storage chamber 3 are sealed by the fixing piece 9 and the sealing ring 10. The closing piece 15 is fixedly connected to the outer combined pipe fitting 12 and the fixing rod 11 and sealed. The tensioning piece 14 is annular as a whole and has a wavy cross-section. The tensioning piece 14 is adapted to the tensioning chamber 13. The tensioning piece 14 can provide a tensioning effect, so that the threads on the outer side of the outer combined pipe fitting 12 will be more tightly pressed against the inner wall of the liquid storage chamber 3 to ensure the sealing effect; a groove adapted to the fixing piece 9 is provided at one end of the operating main rod 5 in the liquid storage chamber 3, and the sealing ring 10, the outer combined pipe fitting 12, and the closing piece 15 are all made of fluororubber; the structure of the operating support rod 7 is consistent with the operating main rod 5 except that the threaded hole 16 is not provided.
[0024] The working principle and use process of the utility model are as follows: in actual use, the operating main rod 5 and the operating support rod 7 are twisted by the first rotating member 6 and the second rotating member 8, and the operating main rod 5 moves toward the bottom of the liquid storage chamber 3. At the same time, the operating support rod 7 is twisted in the opposite direction. At this time, the fixing member 9 at the end of the operating support rod 7 will gradually approach the operating main rod 5 until the fixing member 9 is sunk into the groove adapted to the bottom of the operating main rod 5. The rotation of the operating support rod 7 is stopped, and the operating main rod 5 is continued to be rotated, so that the operating main rod 5 and the operating support rod 7 gradually approach the bottom of the liquid storage chamber 3, until the fixing member 9 at the end of the operating support rod 7 is close to the bottom of the liquid storage chamber 3, and the seal is made. The sealing ring 10 will sink into the sealing groove 4 and form a seal between the sealing grooves 4. At this time, the air in the liquid storage chamber 3 will be squeezed out from the suction tube 2. When it is necessary to sample titanium tetrachloride, the suction tube 2 can be inserted into the rubber sealing piece of the titanium tetrachloride storage bottle mouth. At this time, the rubber sealing piece of the titanium tetrachloride storage bottle mouth will form a seal with the suction tube 2, and no air will be involved. Then the operating main rod 5 can be directly rotated. At this time, the operating support rod 7 rotates with the operating main rod 5, and the operating main rod 5 gradually moves away from the bottom of the liquid storage chamber 3. At the same time, the sealing ring 10 also gradually leaves the sealing groove 4. At this time, the suction tube 2 is connected to the liquid storage chamber 3, and the titanium tetrachloride liquid in the titanium tetrachloride storage bottle is filled with water. The liquid storage chamber 3 is entered by the pressure. After absorbing an appropriate amount of titanium tetrachloride liquid, the main operating rod 5 is controlled to remain stationary, and the operating support rod 7 is gradually rotated to make the operating support rod 7 close to the bottom of the liquid storage chamber 3 until the sealing ring 10 is sunk into the sealing groove 4 and the sealing groove 4 is sealed. At this time, the main operating rod 5, the sealing ring 10, and the fixing member 9 will seal the liquid storage chamber 3, and the suction tube 2 and the liquid storage chamber 3 will be sealed by the fixing member 9 and the sealing ring 10. The suction tube 2 can be pulled out from the rubber sealing member on the titanium tetrachloride storage bottle, and the titanium tetrachloride absorbed in the liquid storage chamber 3 will not come into contact with the air. The suction tube 2 is inserted into the titanium tetrachloride storage bottle where the titanium tetrachloride is needed. In the device, repeating the same steps as above can squeeze out the titanium tetrachloride liquid from the liquid storage chamber 3, and repeated operations can be performed for multiple samplings. In the above process, the threaded connection between the operating main rod 5 and the liquid storage chamber 3 is subject to the outward tightening effect of the tightening member 14, and the threads on the outer side of the outer combined pipe fitting 12 will be more tightly pressed against the inner wall of the liquid storage chamber 3 to ensure the sealing effect. Since the structure of the operating support rod 7 is consistent with that of the operating main rod 5 except that the threaded hole 16 is not provided, the operating support rod 7 and the threaded hole 16 also have a tightening and sealing effect. Titanium tetrachloride will not come into contact with the air after entering the sampler, which can avoid reaction with the air and reduce safety hazards.
