[0026] The fixing structure 4 comprises a fixing plate 401, a plurality of through grooves 403 are provided on the top of the fixing plate 401, the through grooves 403 are matched with the outer tube wall of the placement tube 10, a liquid discharge groove 402 is provided on the top of the fixing plate 401 and on both sides of the through grooves 403, liquid is placed in the liquid discharge groove 402, a soft film 404 is provided on the top of the inner wall of the liquid discharge groove 402, and the soft film 404 is sealed to prevent liquid from flowing out, support plates 11 are fixedly provided on both sides of the top of the fixing plate 401, and rubber pads 12 are fixedly provided on both sides of the bottom of the fixing plate 401, a display screen 5 is provided on the front of the detection machine 2, and a control terminal 7 is provided on one side of the front of the detection machine 2, a pressure cover 3 is rotatably provided on the top of the supporting plate 11, and movable buckles 9 are rotatably provided on the front and rear sides of the top of the other supporting plate 11, a sealing film 8 is provided on the top of the placement tube 10, and the tubular structure 6 comprises a top ring 604, the top ring 604 is annular, and the inner wall of the top ring 604 is aligned with the top of the outer wall of the placement tube 10 The top of the top ring 604 is provided with an annular groove, and a water absorption ring 607 is arranged in the annular groove. Water guide needles 606 are fixedly arranged on the front and rear sides of the bottom of the water absorption ring 607. The bottom of the water guide needle 606 penetrates the top ring 604 and extends to the outside of the top ring 604. The material of the water guide needle 606 is a hard paper stick. A rubber sheet 608 is arranged on the top of the inner wall of the placement tube 10. The rubber sheet 608 is arranged in a petal-shaped ring. The bottom of the fixed plate 401 is provided with There is a connecting ring 605, and sleeves 602 are fixed on both sides of the bottom of the connecting ring 605. A placement groove is opened at the bottom of the sleeve 602, and a spring 609 is fixed at the bottom of the placement groove. A movable rod 603 is slidably provided at the bottom of the sleeve 602, and the top of the movable rod 603 is fixedly connected to the bottom of the spring 609. A conical seat 601 is provided at the bottom of the movable rod 603, and a conical groove is opened at the top of the conical seat 601, which is adapted to the bottom of the placement tube 10.

[0027] The working principle and use process of the present invention are as follows: when in use, the user first rotates the movable cover 1 to open it, and then aligns the gun head of the sample adding gun with the tube mouth of the placement tube 10. After alignment, a certain pressing force is applied to let the gun head of the sample adding gun push open the rubber sheet 608. While the gun head pushes open the rubber sheet 608, the raw liquid to be tested is injected into the interior of the placement tube 10. During the injection process, the thrust of the gun head cooperates with the deadweight of the raw liquid in the placement tube 10 to drive the top ring 604 to move downward. While the placement tube 10 moves downward, it drives the conical seat 601 to move downward and drives the movable rod 603 to move downward along the sleeve 602 and stretch the spring 609. When the top ring 604 moves to a certain position, it will pierce the soft membrane 404. After the soft membrane 404 is broken, the water guide needle 606 will enter the liquid discharge groove 402. The material of the water guide needle 606 is a water-absorbing material. The water guide needle 606 will suck the liquid in the liquid discharge groove 402 upward and remove all the water on the water guide needle 606 through the water absorption characteristics of the water absorption ring 607. After several inhalations, the originally dry water absorption ring 607 will become wet. At this time, the gun head is pulled out, and the rubber sheet 608 will be closed first to form the first sealing protection and the placement tube 10 will return to the initial position through the rebound force of the spring 609. When testing is needed in the later stage, the sealing film 8 will be covered on the top ring 604. The moist top ring 604 and the sealing film 8 with a flat surface will form a secondary seal between the rubber sheet 608 and the sealing film 8 through surface tension. In addition to forming a seal, the surface tension can also prevent the wind force caused by the rapid opening of the pressure cover 3 from driving the sealing film 8 to move, causing aerosol infection. Finally, during the test, the pressure cover 3 is rotated to close, and after closing, it is firmly fastened by the movable buckle 9. Then the movable cover 1 can be closed to start the detection machine 2 to perform genetic testing on the original liquid. When the test liquid is less and a lot of placement tubes 10 are not needed, the placement tube 10 can also be slid out of the fixed plate 401 according to actual needs, and then put back when used.

The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
