[0029] The pressing module 1 includes a circular guide rod 11, which passes through a circular guide hole 210. The circular guide hole 210 is set at one end of an L-shaped rod 26. The L-shaped rod 26 is fixedly connected to the upper end of one side of the square tube 29, and the lower ring spring 12 of the circular guide rod 11.

[0030] One end of the spring 12 is fixedly connected to the lower side of the L-shaped rod 26 , and the other end of the spring 12 is fixedly connected to the upper end of the L-shaped sliding rod 16 .

[0031] One side of the L-shaped slide rod 16 is fixedly connected to the corresponding square sleeve 14 , and the square tube 29 is arranged in a corresponding group of the square sleeves 14 .

[0032] One side of a group of the square sleeves 14 is respectively fixedly connected to the corresponding connecting rods 15 , and one side of a group of the connecting rods 15 is respectively fixedly connected to the corresponding cover plates 2 13 .

[0033] A sealing gasket fixedly provided on the lower side of a set of the cover plates 13 matches a circular hole provided in the middle of a set of the cover plates 1 25 .

[0034] Working principle: first, turn the knob 21, the knob 21 drives the screw rod 22 to rotate, the screw rod 22 drives the square tube 23 to move upward, the square tube 23 drives a group of sliders 24 to slide along the corresponding slide groove 27, so that a group of sliders 24 drives the corresponding cover plate 1 25 to move upward, when a group of cover plate 1 25 contacts the cover plate 2 13, a group of cover plate 1 25 drives a group of cover plate 2 13 to move upward, a group of cover plate 2 13 drives the square sleeve 14 to move upward through the connecting rod 15, so that a group of square sleeves 14 drives the L-shaped slide rod 16 to move upward, the L-shaped slide rod 16 drives the circular guide rod 11 to move upward along the circular guide hole 210, so that the spring 12 is compressed, and then stop turning the knob 21, as shown in FIG. Figure 2 As shown, the cover plate 25 is separated from the group of circular ferrules 28. At this time, a group of sampling tubes 3 are placed on the corresponding circular ferrules 28, and then the knob 21 is reversed. Next, the movement direction of some parts of the device is opposite to the above movement direction, so it is not repeated. The group of cover plates 1 25 are respectively contacted with the corresponding sampling tubes 3, so that the group of cover plates 1 25 covers the upper side of the corresponding sampling tubes 3. At the same time, the spring 12 rebounds, so that the sealing gasket fixed on the lower side of the group of cover plates 2 13 covers the circular hole provided in the middle of the group of cover plates 1 25, as shown in FIG.

At the same time, the L-shaped slide bar 16 drives a group of square sleeves 14 to move upward along the square tube 1 29, and a group of square sleeves 14 drives the cover plate 2 13 to move upward through the corresponding connecting rod 15, so that a group of cover plates 1 25 are exposed, so that water passes through a group of cover plates 1 25. The round hole provided in the upper part enters into the sampling tube 3, and water of different depths can be sampled. Then, the cross bar of the L-shaped sliding rod 16 is loosened to make the spring 12 rebound, so that the sealing gasket fixed on the lower side of the cover plate 2 13 covers the round hole provided in the middle part of a set of cover plates 1 25. Then, the L-shaped rod 26 is held to take the device out of the water, and then the knob 21 is turned. The above actions are repeated to make the cover plate 1 25 press against the cover plate 2 13 to leave the sampling tube 3, and then the sampling tube 3 is removed to detect the water sample in the sampling tube 3.

[0036] Beneficial effect: Through the cooperation of the adjustment module 2 and the pressing module 1, the placement and removal of the sampling tube 3 can be completed. By pressing the module 1, the cover plate 2 13 can be separated from the cover plate 1 25, so that a group of cover plates 1 25 are exposed, and water can enter the sampling tube 3 through the circular hole provided in the middle of a group of cover plates 1 25. Water at different depths can be sampled. The whole operation is relatively convenient, saving time and effort.
