Through the action of the connecting block 2, the nucleic acid sampling tube 4 is fixed between the two fixed support blocks 1, and then the limit protection plate 6 and the fixed cover 5 are flipped back to their original positions, and the throat swab is passed through the hole in the middle part of the limit protection plate 6 into the inner cavity of the nucleic acid sampling tube 4. The limit protection plate 6 is used to limit and protect the fingers of the personnel, thereby preventing accidents. At this time, the fixed support block 1 is used to break the rod of the throat swab, which is convenient for medical staff to use.

[0030] like Figure 2-Figure 4 As shown, the nucleic acid sampling tube cover 3 includes a sealing cover 31, the inner cavity of the sealing cover 31 is movably sleeved with the outer wall of the upper part of the nucleic acid sampling tube 4, the top of the inner cavity of the sealing cover 31 is fixedly connected with a threaded inner shell 32, the outer wall of the threaded inner shell 32 is threadedly sleeved with the inner wall of the upper part of the nucleic acid sampling tube 4, and the bottom of the inner wall of the upper surface of the sealing cover 31 is fixedly connected with a fixed inclined plate 33;

[0031] By rotating the limit protection plate 6, the limit protection plate 6 and the fixed cover 5 are rotated to the right side of the fixed support block 1, and then the sealing cover 31 is rotated by rotating the fixed inclined plate 33, so that the outer wall of the fixed inclined plate 33 is separated from the inner wall of the nucleic acid sampling tube 4, thereby opening the upper surface of the nucleic acid sampling tube 4, wherein the fixed inclined plate 33 acts to facilitate medical staff to unscrew the sealing cover 31.

[0038] like Figure 6 , Figure 7 As shown, the inner cavities of the front and rear parts of the U-shaped limiting plate 113 are slidably connected to the limiting slide plate 114, and the left sides of the two limiting slide plates 114 are fixedly connected to the front and rear parts of the right side of the fixing plate 111 respectively;

[0039] Through the action of the limiting slide plate 114, the U-shaped limiting plate 113 can stably move left and right in the inner cavity of the fixed support block 1, thereby preventing shaking and displacement during the movement.

[0040] The auxiliary component 11 includes a fixed plate 111, the left side of the fixed plate 111 is fixedly connected to the inner cavity of the fixed support block 1, the middle part of the right side of the fixed plate 111 is fixedly connected with a hydraulic rod 112, the output end of the hydraulic rod 112 is fixedly connected with a U-shaped limiting plate 113, and the right side of the U-shaped limiting plate 113 is fixedly connected with a U-shaped fixed plate 115; the bottom of the inner wall of the U-shaped fixed plate 115 is overlapped with a tool fixing plate 116, the right side of the tool fixing plate 116 is fixedly connected with a tool 117, the inner wall of the tool fixing plate 116 is clamped with a clamping plate 118, the upper surface of the clamping plate 118 is fixedly connected to a limiting plate 119, the front and rear parts of the upper surface of the limiting plate 119 are fixedly connected to a limiting slide plate 1110, and the two limiting slide plates 1110 are fixedly connected to each other. The outer walls of 1110 are respectively movably sleeved with the inner cavity of the upper part of the U-shaped fixing plate 115, the upper surfaces of the two limiting slide plates 1110 are fixedly connected with the connecting plate 1111 and the connecting plate 1111 is located on the upper surface of the U-shaped fixing plate 115, the middle part of the upper surface of the limiting plate 119 is fixedly connected with two telescopic rods 1112 and the two telescopic rods 1112 are located between the two limiting slide plates 1110, the upper surfaces of the two telescopic rods 1112 are fixedly connected with the top of the inner wall of the U-shaped fixing plate 115, the outer walls of the two telescopic rods 1112 are movably sleeved with the return springs 1113, and the upper and lower sides of the two return springs 1113 are respectively fixedly connected with the limiting plate 119 and the opposite surfaces of the inner wall of the upper part of the U-shaped fixing plate 115;

[0041] Through the action of the hydraulic rod 112, the U-shaped limit plate 113 moves to the right under the action of the limit slide 114, so that the U-shaped fixing plate 115 drives the tool fixing plate 116 and the tool 117 to move to the right. Through the relative movement of the two tools 117, the rod of the pharyngeal swab is cut off, and the lower part of the pharyngeal swab falls into the inner cavity of the nucleic acid sampling tube 4. When the tool 117 needs to be replaced, the limit plate 119 can be moved upward by moving the connecting plate 1111 upward under the action of the limit slide 1110, so that the card plate 11 8 leaves the inner cavity of the tool fixing plate 116. At this time, the tool fixing plate 116 and the tool 117 are pulled out and replaced, and the new tool fixing plate 116 and the tool 117 are replaced on the bottom of the inner wall of the U-shaped fixing plate 115, and then the connecting plate 1111 is loosened, so that the limit plate 119 moves downward under the action of the return spring 1113 and the telescopic rod 1112, so that the clamping plate 118 is clamped into the inner cavity of the replaced tool fixing plate 116, thereby fixing the tool fixing plate 116 and the tool 117, so as to facilitate disassembly, replacement and fixation.

[0042] The working principle of the utility model is as follows: first, by rotating the limit protection plate 6, the limit protection plate 6 and the fixed cover 5 are rotated to the right side of the fixed support block 1, and then by rotating the fixed inclined plate 33, the sealing cover 31 is rotated, so that the outer wall of the fixed inclined plate 33 is separated from the inner wall of the nucleic acid sampling tube 4, so that the upper surface of the nucleic acid sampling tube 4 is opened, and after opening, the nucleic acid sampling tube 4 is placed into the inner cavity of the connecting block 2, and the nucleic acid sampling tube 4 is fixed between the two fixed support blocks 1 through the action of the connecting block 2, and then the limit protection plate 6 is rotated. The limiting protective plate 6 and the fixed cover 5 are flipped back to their original positions, and the pharyngeal swab is passed through the hole in the middle of the limiting protective plate 6 into the inner cavity of the nucleic acid sampling tube 4. At this time, the hydraulic rod 112 causes the U-shaped limiting plate 113 to move to the right under the action of the limiting slide plate 114, so that the U-shaped fixing plate 115 drives the tool fixing plate 116 and the tool 117 to move to the right. The two tools 117 move toward each other, so that the rod of the pharyngeal swab is cut off, and the lower part of the pharyngeal swab falls into the inner cavity of the nucleic acid sampling tube 4. When multiple pharyngeal swabs are inserted into the inner cavity of the nucleic acid sampling tube 4, After the tube is full, the fixed cover 5 and the limiting protection plate 6 are rotated to the right side of the fixed support block 1 to take out the nucleic acid sampling tube 4, and then the threaded inner shell 32 is threadedly connected with the inner wall of the nucleic acid sampling tube 4 by rotating the sealing cover 31 to complete the sampling, which is convenient for medical staff to use. When the tool 117 needs to be replaced, the limiting plate 119 can be moved upward by moving the connecting plate 1111 upward under the action of the limiting slide plate 1110, so that the clamping plate 118 is removed from the tool fixing plate 116. The tool fixing plate 116 and the tool 117 are removed from the inner cavity and replaced. The new tool fixing plate 116 and the tool 117 are replaced at the bottom of the inner wall of the U-shaped fixing plate 115. Then the connecting plate 1111 is loosened, and the limit plate 119 moves downward under the action of the return spring 1113 and the telescopic rod 1112, so that the clamping plate 118 is clamped into the inner cavity of the replaced tool fixing plate 116, thereby fixing the tool fixing plate 116 and the tool 117, which is convenient for disassembly, replacement and fixation.
