[0002] Plant virus infections can cause serious losses to agricultural production. Plant virus detection and prevention play an important role in modern agricultural production. Due to the low concentration and uneven distribution of plant viruses in plant tissues, plant virus detection samples are generally taken from plant tissues such as stems and leaves. Juice is extracted by grinding, pressing and other methods to obtain sufficient virus particles for subsequent analysis.

[0003] Traditional methods of placing and securing plant samples have several drawbacks. On the one hand, it is difficult to disassemble the containers holding the plant samples, making the process inconvenient. After the samples are processed, it is also difficult to clean the containers, which can easily lead to cross-contamination during subsequent reuse and affect the accuracy of experimental or processing results. On the other hand, traditional methods cannot guarantee the stability of the containers holding the plant samples during operation, and they are prone to loosening or displacement. This not only poses safety hazards to the operation but also reduces the reliability of the experimental or processing process.

[0004] Therefore, it is necessary to design a plant virus detection sample extraction device to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the above-mentioned technical problems, this invention proposes a plant virus detection sample extraction device. It solves the problem that in the traditional sample placement and fixing method, it is difficult to easily disassemble the container holding the plant sample when processing plant samples. This makes the process inconvenient and makes it difficult to clean the container after sample processing, which can easily lead to cross-contamination problems during subsequent secondary use.

[0006] The technical solution of this utility model is:

[0007] This utility model proposes a plant virus detection sample extraction device, including a fixed frame, on which an assembly mechanism and a squeezing mechanism are provided;

[0008] The assembly mechanism includes a support base fixedly connected to the bottom wall of the fixed frame, and an extraction cylinder is fixedly connected to the top of the support base;

[0009] The inner wall of the extraction cylinder is fixedly connected to a fixing plate. The top surface of the fixing plate is fixedly connected to a plurality of sliding rods arranged in a circumferential array. The outer walls of the plurality of sliding rods arranged in a circumferential array are slidably connected to a positioning disc one. The outer walls of the plurality of sliding rods are slidably connected to a positioning disc two. The positioning disc two is in contact with the top of the positioning disc one. The outer walls of the plurality of sliding rods arranged in a circumferential array are all wound with springs. One end of the spring is fixedly connected to the top surface of the fixing plate, and the other end of the spring is fixedly connected to the bottom surface of the positioning disc one. The bottom of the positioning disc two is fixedly connected to a filter cylinder.

[0010] Preferably, the filter cartridge is located inside the extraction cartridge, and the bottom of the filter cartridge has several filter holes, including a threaded rod rotatably connected to the inner wall of the support base, and a fixing rod is fixedly connected to the top of the support base.

[0011] Preferably, a knob is fixedly connected to the top of the threaded rod, a connecting plate is threadedly connected to the outer wall of the threaded rod, and the fixed rod slides through the connecting plate.

[0012] Preferably, a rotating rod extends through the connecting plate, and a handle is fixedly connected to the top of the rotating rod.
