One side is fixedly connected with an insert block 9, and a side of the limit plate 6 close to the adjusting plate 8 is provided with a plurality of slots 15 used in conjunction with the insert block 9. The staff pushes the adjusting plate 8 into the adjusting slot 7, and the adjusting plate 8 drives the insert block 9 to release the limit between the insert block 9 and the slot 15. The staff pulls the limit plate 6 to drive the fastening plate 4 to move, so that the fastening plate 4 drives the filtration rubber tube 2 to be inserted into the filter hole. After adjusting the limit plate 6 to the applicable position, the insert block 9 is aligned with the slot 15 and inserted to limit the position of the limit plate 6. Through this arrangement, the staff can avoid the filtration rubber tube 2 from falling off due to external factors during filtration.

[0023] Reference Figure 1 , Figure 2 and Figure 4 As shown, in this implementation scheme: the side of the adjustment plate 8 close to the adjustment slot 7 is fixedly connected with a force storage spring 10, and the side of the force storage spring 10 away from the adjustment plate 8 is fixedly connected to the inside of the adjustment slot 7. When the staff pushes the adjustment plate 8 toward the inside of the adjustment slot 7, the adjustment plate 8 squeezes the force storage spring 10 to compress and store force, and at the same time drives the plug block 9 to release the limit between the plug block 9 and the slot 15. The staff aligns the plug block 9 with the slot 15 and releases the adjustment plate 8. Under the action of the rebound force of the force storage spring 10, the adjustment plate 8 is quickly pushed, and the plug block 9 is driven to be inserted into the force storage spring 10 for fixation.

[0024] Reference Figure 1 , Figure 2 and Figure 4As shown, in the present embodiment: slide grooves 11 are provided on both sides of the adjusting groove 7, sliders 12 are fixedly connected on both sides of the adjusting plate 8, and the surface of the slider 12 is slidably connected to the inside of the slide groove 11. When the staff slides the adjusting plate 8, the adjusting plate 8 drives the slider 12 to slide inside the slide groove 11. Through the above arrangement, the slider 12 can maintain a stable motion trajectory during the sliding process inside the slide groove 11, thereby avoiding deviation or jamming caused by friction or external interference.

[0025] Reference Figure 3 and Figure 5 As shown, in this embodiment: sliding grooves 13 are provided at both ends of the adjusting block 5, and sliding blocks 14 are fixedly connected at both ends of the limiting plate 6. The surface of the sliding block 14 is slidably connected to the inside of the sliding groove 13. When the staff moves the limiting plate 6, the limiting plate 6 drives the sliding block 14 to slide inside the sliding groove 13. Through the above arrangement, the sliding process not only ensures the overall stability of the device, but also makes the contact between the sliding block 14 and the sliding groove 13 closer, reducing friction and wear.

[0026] Reference Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment: the material of the solution filter 3 is glass product. The setting of the solution filter 3 as a glass product makes the filtration operation more intuitive and easy to observe. During the operation, the user can clearly see the process of the filtrate gradually separating from the sample, which helps to accurately judge the progress and effect of the filtration. At the same time, the filtration cup solution filter 3 made of glass has good chemical stability and can resist the erosion of various chemical reagents, thereby ensuring the safety and reliability of the filtration process.

[0027] Reference Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment: the size of the plug block 9 is adapted to the size of the slot 15, and the surface of the plug block 9 is slidably connected to the inside of the slot 15. By configuring the size of the plug block 9 to be adapted to the size of the slot 15, the sliding connection between the plug block 9 and the slot 15 ensures smooth operation between the two, which can maintain a stable connection state and achieve a flexible motion trajectory, making the entire system more efficient during use and reducing unnecessary friction and loss.

By setting the suction filtration rubber tube 2 to be made of rubber, the suction filtration rubber tube 2 has certain flexibility and durability. The rubber material not only has excellent sealing performance and can effectively prevent the leakage of liquid or gas, but also has good corrosion resistance and can adapt to various complex working environments. In addition, the rubber material also has good wear resistance and impact resistance, so that the suction filtration rubber tube 2 is not easy to be damaged during long-term use, thereby ensuring the stability and reliability of the equipment.

[0029] Working principle: the staff pushes the adjusting plate 8 into the adjusting slot 7, and the adjusting plate 8 drives the plug block 9 to release the limit between it and the slot 15. The staff pulls the limit plate 6 to drive the fastening plate 4 to move, so that the fastening plate 4 drives the filtration rubber tube 2 to be inserted into the filter hole. After adjusting the limit plate 6 to the applicable position, the plug block 9 is aligned with the slot 15 and inserted to limit the position of the limit plate 6. Through this setting, the staff can avoid the filtration rubber tube 2 from falling off due to external factors during filtration. When the staff pushes the adjusting plate 8 into the adjusting slot 7, the adjusting plate 8 squeezes the force storage spring 10 to compress and store force, and at the same time drives the plug block 9 to release the limit between it and the slot 15. The operator aligns the plug block 9 with the slot 15 and releases the adjustment plate 8. Under the action of the rebound force of the storage spring 10, the adjustment plate 8 is quickly pushed, and the plug block 9 is driven to be inserted into the storage spring 10 for fixation. When the operator slides the adjustment plate 8, the adjustment plate 8 drives the slider 12 to slide inside the slide groove 11. Through the above arrangement, the slider 12 can maintain a stable motion trajectory during the sliding process inside the slide groove 11, avoiding the deviation or jamming caused by friction or external force interference. When the operator moves the limit plate 6, the limit plate 6 drives the sliding block 14 to slide inside the sliding groove 13. Through the above arrangement, the sliding process not only ensures the stability of the device The overall stability of the filter cup 14 also makes the contact between the sliding block 14 and the sliding groove 13 closer, reducing friction and wear. The solution filter 3 is a glass product, which makes the filtration operation more intuitive and easy to observe. During the operation, the user can clearly see the process of the filtrate gradually separating from the sample, which helps to accurately judge the progress and effect of the filtration. At the same time, the glass filtration cup solution filter 3 has good chemical stability and can resist the erosion of various chemical reagents, ensuring the safety and reliability of the filtration process. The size of the plug block 9 is matched with the size of the slot 15, and the sliding connection between the plug block 9 and the slot 15 ensures The smooth operation between the two can not only maintain a stable connection state, but also realize a flexible movement trajectory, making the entire system more efficient during use and reducing unnecessary friction and loss. By setting the suction rubber tube 2 to be made of rubber, the suction rubber tube 2 has a certain flexibility and durability. The rubber material not only has excellent sealing performance and can effectively prevent the leakage of liquid or gas, but also has good corrosion resistance and can adapt to various complex working environments. In addition, the rubber material also has good wear resistance and impact resistance, which makes the suction rubber tube 2 not easily damaged during long-term use, thereby ensuring the stability and reliability of the equipment.
