In the actual operation process, the sampling tube needs to be used in cooperation with a lid to break off the sampling stick. After the sampling stick is broken off, the lid is placed aside, making the mouth of the sampling tube open, resulting in the sample being easily contaminated. In addition, using the lid to cooperate with the tube body to break off the sampling stick is inconvenient in the actual operation process.

[0004] Therefore, the sampling tubes in the prior art have the technical problems of inconvenient operation and easy contamination of nucleic acid. Summary of the Invention

[0038] The following specific embodiments shown are intended to be descriptions of various configurations of the technical solution of the subject matter of the present utility model, and are not intended to represent the only configurations in which the technical solution of the subject matter of the present utility model can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the technical solution of the subject matter of the present utility model. However, it will be clear and obvious to those skilled in the art that the technical solution of the subject matter of the present utility model is not limited to the specific details shown herein, and can be practiced without these specific details.

[0039] Refer to Figures 1 to 6As shown in the figure, a biological sample sampling tube includes a tube body 1, and a cover body 2 for covering the tube body 1 is provided on the tube body 1. A cutting component 3 for cutting the handle of the sampling cotton swab is provided between the cover body 2 and the tube body 1;

[0040] The cutting component 3 includes a lower cover installed on the tube body 1 and an upper cover provided on the lower cover. A cutting piece 31 is provided between the upper cover and the lower cover. The cutting piece 31 is rotatably connected between the lower cover and the upper cover. The cutting piece 31 is provided with a cutting groove 311, and cutting edges are provided on opposite side walls of the cutting groove 311;

[0041] The cutting piece 31 is further provided with a handle 312 for facilitating the rotation of the cutting piece 31;

[0042] The upper cover is provided with an upper through hole 334, and the lower cover is provided with a lower through hole 322. The upper through hole 334 and the lower through hole 322 are coaxially arranged;

[0043] An elastic member 313 is provided between the handle 312 and the lower cover to stagger the cutting groove 311 from the upper through hole 334 and the lower through hole 322.

[0044] After the sampling personnel complete sampling, they operate the handle 312 to overcome the elastic force of the elastic member 313, so that the cutting groove 311 communicates with the upper through hole 334 and the lower through hole 322. The cotton swab head sequentially passes through the upper through hole 334, the cutting groove 311, and the lower through hole 322 and enters the tube body 1. Then, continue to operate the handle 312 to rotate the cutting piece 31, so that the cutting edge cuts the handle of the sampling cotton swab. Then, release the handle 312. Under the action of the elastic member 313, the cutting piece 31 rotates reversely by an angle, and the cutting groove 311 is staggered from the upper through hole 334 and the lower through hole 322 to prevent the sample in the tube body 1 from being contaminated.

[0045] Or, after the cotton swab head sequentially passes through the upper through hole 334, the cutting groove 311, and the lower through hole 322 and enters the tube body 1, release the handle 312. Under the action of the elastic member 313, the cutting piece 31 rotates reversely by a certain angle, and the elastic force of the elastic member 313 is used to cooperate with the cutting edge to cut the handle of the sampling cotton swab. And at the same time, the cutting groove 311 is staggered from the upper through hole 334 and the lower through hole 322 to prevent the nucleic acid from being contaminated.

[0046] Refer to Figures 1 to 6 As shown in the figure, in some embodiments, the lower cover includes a cylinder body 32. The cylinder body 32 is provided with a lower cover portion 321 for covering the tube body 1. The lower cover portion 321 and the cylinder body 32 are of an integral structure. The lower through hole 322 is provided in the lower cover portion 321. The cylinder body 32 is further provided with an arc-shaped groove 323 for the handle 312 to extend out of the cylinder body 32. The arc-shaped groove 323 penetrates the side wall of the cylinder body 32.

[0047] The diameters of the upper through hole 334 and the lower through hole 322 are both larger than the diameter of the cotton swab head, and the width of the cutting groove 311 is larger than the diameter of the cotton swab head.

[0048] In some embodiments, a part of the upper cover is located inside the barrel 32. The upper cover includes an upper cover portion 33 and an annular portion 331 provided on the upper cover portion 33. The upper through hole 334 is provided on the upper cover portion 33. The upper cover portion 33 is located inside the body. The upper cover portion 33 cooperates with the lower cover portion 321, which can define the axial degree of freedom of the cutting piece 31, improve the rotation accuracy of the cutting piece 31, and prevent the cutting piece 31 from moving axially.

[0049] In some embodiments, the annular portion 331 is fixed inside the barrel 32 by a thread, and the annular portion 331 is further provided with a lapping portion 332 lapping on the upper end surface of the barrel 32. The annular portion 331, the lower cover portion 321, and the lapping portion 332 are of an integral structure.

[0050] Refer to Figures 1 to 6 As shown, in some embodiments, the annular portion 331 is provided with an external thread, and the cover body 2 is provided with an internal thread that cooperates with the external thread of the annular portion 331.

[0051] In some embodiments, the upper cover portion 33 is provided with a rotating shaft 333. The rotating shaft 333 and the upper cover portion 33 are of an integral structure. The cutting piece 31 is provided with a shaft hole that cooperates with the rotating shaft 333. The axis of the rotating shaft 333 is coaxial with the axis of the upper cover portion 33.

[0052] In some embodiments, the lower cover is fixed to the tube body 1 by a thread. The tube body 1 is provided with an external thread that cooperates with the cover body 2, and the barrel 32 is provided with an internal thread that cooperates with the external thread of the tube body 1.

[0053] The internal thread provided on the cover body 2 can cooperate with the annular portion 331 and with the tube body 1. Therefore, the cover body 2 can be fixed to the annular portion 331 or to the tube body 1. For example, when the number of sampling cotton swab heads in the tube body 1 reaches a certain amount, the cutting assembly 3 is removed from the tube body 1, and the cover body 2 is directly covered on the tube body 1 to achieve the sealing of the tube body 1. After the cutting assembly 3 is disinfected, it can be used in cooperation with a new tube body 1. Thus, the cutting assembly 3 can be reused.

[0054] Refer to Figures 1 to 6 As shown, in some embodiments, the lower cover is further provided with a handle portion 324 that facilitates the operation of the handle 312. The handle portion 324 and the lower cover are of an integral structure.

[0055] The elastic member 313 is a spring. One end of the spring is fixed to the handle 312, and the other end of the spring contacts the shank 324.

[0056] The handle 312 and the cutting piece 31 are of an integral structure.

[0057] During the actual operation process, when operating the handle 312, the thumb can be used to contact the shank 324, and then the index finger is used to operate the handle 312. By applying a force with the index finger, the handle 312 can be rotated. Therefore, by providing the shank 324, the handle 312 can be made easier to operate.

[0058] The above has introduced the technical solution of the main theme of the present invention and the corresponding details. It can be understood that the above introduction is only some implementation schemes of the technical solution of the main theme of the present invention, and some details can also be omitted during its specific implementation.

[0059] In addition, in some implementation schemes of the above-mentioned invention, it is possible to combine multiple implementation schemes. Due to space limitations, various combination schemes are not listed one by one. Those skilled in the art can freely combine and implement the above implementation schemes according to their needs during the specific implementation to obtain a better application experience.
