[0022] Example:

[0023] As attached Figure 1 To the attached Figure 4 As shown:

[0024] The utility model provides a high-precision biological sample collection device, comprising a barrel 1, the bottom end of the barrel 1 is connected to a connecting ring 2, the bottom end of the connecting ring 2 is connected to a connecting block 3, the connecting block 3 is movably connected to an extraction needle, an equipment slot 4 is opened inside the barrel 1, the top end of the barrel 1 is movably connected to a sealing cylinder 5, the bottom end of the sealing cylinder 5 is connected to a threaded ring 6, the threaded ring 6 is movably connected to the notch position of the equipment slot 4, and an extraction device is arranged in the equipment slot 4.

[0025] Among them, the extraction device includes a collecting tube 7, a collecting block 8, a sealing block 9, a pull rod 10, a handle 11 and a pair of rubber rings 12. A collecting groove 13 is opened at the top of the collecting tube 7. The collecting groove 13 runs through the top and bottom ends of the collecting tube 7. The collecting block 8 is located inside the collecting groove 13. The sealing cover block 9 is fixedly connected to the bottom end of the collecting tube 7. A pair of rubber rings 12 are sleeved on the top and bottom ends of the collecting block 8. The collecting block 8 is fixedly connected to the pull rod 10 on the side away from the rubber ring 12. One end of the pull rod 10 extends to the outside of the collecting tube 7. The pull rod 10 is fixedly connected to the handle 11 at one end located outside the collecting tube 7.

[0026] Among them, a plurality of scales 14 are set on the outside of the collection tube 7, and a connecting groove 15 is opened at the bottom end of the sealing block 9. The connecting groove 15 runs through the top and bottom ends of the sealing block 9. The setting of the scale 14 facilitates the observation of the collection amount of the biological sample.

[0027] The bottom end of the connecting block 3 is fixedly connected to a fixing ring 16 , and a fixing groove 17 is formed at the bottom end of the fixing ring 16 . The fixing groove 17 passes through the top and bottom ends of the fixing ring 16 , and the fixing groove 17 is communicated with the connecting groove 15 .

[0028] Among them, the extraction needle includes a collection needle 18 and a fixed cylinder 19. The collection needle 18 passes through the top and bottom ends of the fixed cylinder 19. Several threads 20 are provided on the outside of the fixed cylinder 19. The fixed cylinder 19 is connected to the fixed groove 17 through the threads 20. One end of the collection needle 18 passes through the connecting groove 15 and extends into the collection groove 13, which makes it convenient for the collection needle 18 to change the size according to needs.

[0029] A glass observation piece 21 is provided on the outer side of the cylinder 1 , and the glass observation piece 21 can facilitate the experimenter to observe the collection degree of the biological sample.

[0030] The cylinder 1 is made of stainless steel, which not only has high strength but also has good corrosion resistance and high temperature resistance.

[0031] Working principle of this embodiment: When collecting biological samples, the experimenter selects an extraction needle of appropriate size according to the biological sample, aligns the thread 20 of the fixed cylinder 19 with the fixed groove 17, and then connects the fixed cylinder 19 to the fixed ring 16 through the thread 20 so that one end of the collection needle 18 extends into the collection groove 13 through the connecting groove 15. After the collection needle 18 is installed, the biological sample can be collected. The needle tip of the collection needle 18 is aligned with the biological sample, and then the handle 11 is pulled up. The handle 11 drives the pull rod 10 to move in the collection groove 13, and the pull rod 10 drives the collection block 8 in the collection groove 13. The collecting block 8 moves inside the collecting groove 13, and the rubber ring 12 on the collecting block 8 generates pressure when moving, so that the needle tip of the collecting needle 18 sucks the biological sample into the collecting groove 13. The experimenter can observe the scale 14 according to the glass observation piece 21 of the cylinder 1. After the collection is completed, the experimenter only needs to turn the entire collecting device upside down to prevent the biological sample from falling. When the experimenter needs to take out the biological sample for experimental research, he only needs to align the needle tip of the collecting needle 18 with the place where the biological sample is placed and press the handle 11 toward the collecting groove 13. The pressure will discharge the biological sample in the collecting groove 13 out of the collecting groove 13 through the collecting needle 18.
