In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures are not described in detail to avoid unnecessarily obscuring the understanding of these embodiments. In addition, all embodiments may be used in combination with each other. Example 1

[0023] See also Figure 1 - Figure 2The utility model provides a technical solution: a base plate 1, an analyzer 3 and a chassis 2 are installed on the upper surface of the base plate 1, the analyzer 3 is used to decompose and analyze liquids, and a screen is provided on the chassis 2, and the analyzed data will be displayed on the screen. The chassis 2 is arranged on one side of the analyzer 3, and a complex electronic circuit is arranged inside the chassis 2. A drive device box 4 is installed on the upper surface of the analyzer 3, and a drive device is arranged inside the drive device box 4 to provide power for sucking liquid. A shelf device 5 is provided on the upper surface of the drive device box 4, and the shelf device 5 is used to place glass bottles. The shelf device 5 includes a lifting assembly 6 and a bracket body 24, and the lifting assembly 6 is arranged above the bracket body 24. The lifting assembly 6 can move up and down above the bracket body 24, and a plurality of pillars 7 are provided in the middle of the bracket body 24. The plurality of pillars 7 connect the top and bottom of the bracket body 24 together, and each of the pillars 7 is provided with a slide groove 25, which is provided for the lifting assembly 6 to lift and lower.

[0024] During actual use, the lifting assembly 6 can be adjusted according to the size of the glass bottle to be placed so that it is in a suitable position so that the glass bottle will not be easily touched or fall. Example 2

[0025] See also Figure 1 - Figure 2 On the basis of the first embodiment, the lifting assembly 6 includes a lifting plate 13 and a lifting leg 14, and the plurality of lifting legs 14 are respectively extended into the plurality of slide grooves 25 and slidably connected thereto. The number of the lifting legs 14 and the slide grooves 25 is one-to-one corresponding. The lifting plate 13 is fixedly mounted on the top of the lifting legs 14, so the lifting legs 14 slide in the slide grooves 25 to drive the lifting plate 13 to move up and down. The lifting plate 13 and the top plate of the bracket body 24 are both provided with a plurality of first through holes 11, and the first through holes 11 on the two plates are corresponding. The lower surface of the top plate of the bracket body 24 is provided with a plurality of annular plates corresponding to the first through holes 11, so that it can be prevented from being lifted up when it is not needed. When using the lifting plate 13, the glass bottle placed in the first through hole 11 will not be crooked, so that the glass bottle can be placed more upright. A plurality of second through holes 12 are provided on one side of each of the lifting legs 14. The second through holes 12 are used to fix the lifting legs 14 and the pillars 7. A fixing screw 16 is installed on one side of each of the slide grooves 25. The fixing screw 16 and the second through hole 12 can be used in conjunction to fix the lifting leg 14. A third through hole 15 is provided on the top plate of the lifting plate 13 and the bracket body 24. The third through hole 15 is used to place a lid and a conduit when replacing the glass bottle. A material receiving device 17 is installed below the third through hole 15. The material receiving device 17 is used to catch the liquid flowing down the conduit.

[0026] During actual use, after the lifting assembly 6 is lifted to a suitable position, the fixing screw 16 needs to be rotated so that the fixing screw 16 extends into the second through hole 12. The fixing screw 16 and the support 7 are threadedly connected. When the glass bottle needs to be replaced, the unscrewed cap and the catheter need to be placed in the third through hole 15 to prevent the liquid on the catheter from dripping onto the equipment and causing corrosion to the equipment. Example 3

[0027] See also Figure 3 - Figure 4 On the basis of the second embodiment, the material receiving device 17 includes a fixed block 18, a fixed cartridge 19, a limit screw 20 and a limit ring 21. The fixed block 18 is fixedly mounted on the bottom plate 1 of the bracket body 24. The fixed block 18 cannot be moved and plays a certain fixing role. The fixed cartridge 19 is clamped on the fixed block 18. The fixed cartridge 19 is removable. After removal, the liquid therein can be poured out and then installed again. Two connecting cylinders 22 are fixedly connected on both sides of the fixed cartridge 19. A lifting column 23 is provided on the top of each connecting cylinder 22. The lifting column 23 can move up and down. The lifting column 23 extends into the connecting cylinder 22 and is slidably connected thereto. The limit ring 21 is fixedly connected At the top of the lifting column 23, a limiting ring 21 is used to limit the position of the catheter to ensure that the catheter placed in the third through hole 15 enters the fixed cartridge 19 through the limiting ring 21, so that the dripping liquid accurately drips into the fixed cartridge 19. The limiting screw 20 passes through the limiting ring 21 and is threadedly connected to it. The rotation of the limiting screw 20 can adjust the lifting and lowering of the lifting column 23. A plurality of legs 8 are fixedly installed at the bottom of the bracket body 24. Each of the legs 8 can be extended into the top wall of the drive device box 4. A rectangular groove 9 is provided at the bottom of each leg 8. A magnet 10 is installed in each rectangular groove 9. The magnet 10 is used to attract the device below to make its installation and connection effect better, further strengthening the entire device.

[0028] During actual use, the lifting assembly 6 can be adjusted according to the size of the glass bottle to be placed so that it is in a suitable position so that the glass bottle will not be easily touched or fall down. After lifting the lifting assembly 6 to the appropriate position, it is necessary to rotate the fixing screw 16 so that the fixing screw 16 extends into the second through hole 12. The fixing screw 16 and the support 7 are threadedly connected. When the glass bottle needs to be replaced, the unscrewed cover and the catheter need to be placed in the third through hole 15. The catheter will pass through the third through hole 15 into the limiting ring 21. Then, under the restriction of the limiting ring 21, the liquid in the catheter can only drip into the fixed cartridge 19 to prevent the liquid on the catheter from dripping onto the equipment and causing corrosion to the equipment.

[0029] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
