Description

Technical Field

[0001] The invention relates to the technical field of sampling and detection, and in particular to a device for collecting and processing animal epidemic disease samples. Background Art

[0002] The main purpose of sampling and testing feces of diseased livestock is to detect pathogens in animals, including viruses, bacteria, parasites, etc., so as to timely discover and control the spread of animal diseases. Through testing, we can understand the occurrence, epidemic trends and pathogen types of diseases, and provide a scientific basis for the formulation of targeted prevention and control measures.

[0003] The existing Chinese patent with publication number CN117213913B discloses a hot air circulation drying device, but the device and the prior art also have the following defects:

[0004] First, when the hollow sampling rod is inserted into the feces, a cylindrical cavity will be formed in the feces. Then, when the hollow sampling rod rotates, it is difficult for the feces to fall into the sampling slot on the central control sampling rod, which will eventually cause the central control sampling rod to be unable to sample the feces;

[0005] Secondly, in the above patent, even if the central control sampling rod takes out the feces through the sampling slot, the feces in the sampling slot needs to be taken out and put into the sample tube again. During the feces transportation process, the feces will be more or less exposed to external bacteria, causing secondary contamination, which will eventually affect the pathogen detection of the feces itself;

[0006] Third, the feces of diseased livestock are mostly viscous. After sampling the feces, the feces need to be placed in a sample tube. During this process, the feces will adhere to the mouth of the sample tube, which will contaminate the sample tube and is not conducive to the storage of the sample tube. Summary of the invention

Then, the slide plate is slid downward, and the slide plate drives the flap to move downward. When the limit block is separated from the strip limit groove, the flap will be immediately driven by the torsion spring to flip into the square insert. At this time, the inwardly flipped flap will block the lower end of the square insert, and the feces in the square insert cannot leak out from the lower end of the square insert, thereby completing the normal feces sampling operation;

[0018] Secondly, when the feces enters the square insert, the square insert is immediately inverted, and then the feces in the square insert is pressed into the sample tube on the discharge nozzle by pressing down the flap. In the process from sampling to placing the feces in the sample tube, the feces will not come into contact with external bacteria, ultimately ensuring that the pathogens of the disease itself can be detected when testing the feces;

[0019] Thirdly, since the mouth of the sample tube is covered on the discharge nozzle during the process of pressing the feces into the sample tube, when the feces enters the sample tube, the feces will not adhere to the mouth of the sample tube, thereby ultimately preventing the mouth of the sample tube from being contaminated.

DETAILED DESCRIPTION

[0045] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0046] refer to Figures 1 to 24 The animal husbandry disease sample collection and processing device shown in the figure comprises a vertical square insert tube 1, a conical tube 2 is provided at the upper end of the square insert tube 1, a discharge nozzle 3 is provided at the top of the conical tube 2, and a strip opening 4 is provided on one side of the square insert tube 1 (combined with Figure 4 and Figure 5 ), a vertical slide plate 5 is slidably provided on the strip opening 4, the slide plate 5 covers the strip opening 4, a flap 6 is hinged at the lower end of the slide plate 5, a torsion spring 7 is provided between the flap 6 and the slide plate 5, a limit block 8 is provided on the flap 6, a strip limit groove 9 matching with the limit block 8 is provided on the square insert 1, and a notch 10 (such as Figure 1 As shown in the figure, a group of No. 1 resistance blocks and a group of No. 2 resistance blocks are arranged in the square plug 1, the No. 1 resistance block is close to the lower end of the square plug 1, and the No. 2 resistance block is close to the conical tube 2. A slider 11 is slidably arranged on the slide 5, and a flip arm 12 is arranged on the slider 11. A lifting extrusion member is arranged on the flip arm 12. A flap reset member is arranged on the side of the square plug 1 away from the strip opening 4, and the flap reset member includes a rotating frame and a sliding pin 13. One end of the rotating frame is hinged to the outer wall of the square plug 1, and the sliding pin 13 slides on the rotating frame. A through hole 14 corresponding to the sliding pin 13 is opened on the outer wall of the square plug 1 (as shown in the figure). Fig.13 As shown in FIG. 1 ), a sealing sliding cover 15 is provided on the through hole 14.

[0047] In the initial state, the torsion spring 7 releases the elastic force to drive the flap 6 to rotate. At this time, the flap 6 will be horizontal and perpendicular to the slide plate 5. Before collecting feces from diseased livestock, the flap 6 is first flipped vertically, and then the slide plate 5 is slid to make the limit block 8 on the flap 6 inserted into the strip limit groove 9. At this time, the torsion spring 7 is compressed by the flap 6 to generate elastic force, but the flap 6 will not be driven to rotate by the torsion spring 7 through the cooperation of the limit block 8 and the strip limit groove 9. Then the flap 6 will always remain in a vertical state. When collecting feces from diseased livestock, the conical tube 2 arranged on the square insert 1 is first facing upwards, and then the lower end of the entire square insert 1 is inserted into the feces. In this process, the lower end of the square insert 1, the lower end of the slide plate 5 and the flap 6 are all inserted into the feces. At this time, the feces will enter the cavity formed between the square insert 1, the slide plate 5 and the flap 6. Thereafter, the slide plate 5 is slid downward. 5 will drive the flap 6 to move downward. When the limit block 8 is separated from the strip limit groove 9, the flap 6 will be immediately driven by the torsion spring 7 to flip into the square insert tube 1. However, at this time, the square insert tube 1 contains feces, and the flap 6 cannot be completely flipped to a horizontal position due to the resistance of the feces. Therefore, when the flap 6 is flipped, it continues to slide downward on the slide plate 5. Thereafter, the tilted flap 6 will conflict with the No. 1 conflicting block downward. Through the action of the No. 1 conflicting block, the flap 6 is flipped to a level approaching level. When the flap 6 conflicts with the No. 1 conflicting block, the entire square insert tube 1 is pulled out upward. At this time, the inwardly flipped flap 6 will block the lower end of the square insert tube 1, and the feces in the square insert tube 1 cannot leak out from the lower end of the square insert tube 1. When the lower end of the square insert tube 1 is pulled out from the feces, the sample tube is inserted into the discharge nozzle 3, and then the entire square insert tube 1 is inverted. When the square insert tube 1 is inverted (such as Fig.18 As shown in the figure, slide the slide plate 5 downward, the slide plate 5 will drive the flap 6 to descend, during this process, align the limit block 8 with the strip limit groove 9 to ensure that when the slide plate 5 is lowered, the limit block 8 can slide into the strip limit groove 9, so that the flap 6 will always remain in a horizontal state during the descent process, and the feces in the square insert tube 1 will be pressed into the conical tube 2 through the flap 6, and the feces that finally falls into the conical tube 2 will be discharged into the sample tube through the discharge nozzle 3. When the flap 6 descends to near the second resistance block, the limit block 8 slides to the notch 10, and then the flap 6 is turned from a horizontal state to an inclined state through the resistance of the second resistance block. At the same time, the sliding sealing slide cover 15 is slid to open the through hole 14, and the sliding pin 13 is rotated to a horizontal state through the rotating frame (as shown in the figure). Fig. 22 As shown), the sliding pin 13 is then inserted into the square cannula 1 from the through hole 14, and the flap 6 is driven to rotate to a vertical state through the resistance of the sliding pin 13. During this process, the flap 6 will compress the torsion spring 7. When the flap 6 rotates vertically, the sliding plate 5 is slid so that the limit block 8 slides from the notch 10 into the strip limit groove 9. Finally, the flip will remain in a vertical state again. When the flap 6 is vertical, the lifting and extruding member is driven into the square cannula 1 through the flip arm 12, and finally the remaining feces in the square cannula 1 is pressed into the sample tube by the lifting and extruding member (as shown in FIG. Fig.24 As shown), the feces in the square insert tube 1 can be collected by multiple sample tubes. When the sample tube is full, the empty sample tube can be replaced.

[0048] In order to specifically show how the flip is mounted on the slide 5, the following features are provided:

[0049] The bottom of the slide plate 5 is provided with two symmetrical No. 1 circular sleeves 16 (such as Figure 7 As shown in the figure, two symmetrical No. 2 circular sleeves 17 are provided on the top of the flap 6, and the two No. 2 circular sleeves 17 are located between the two No. 1 circular sleeves 16. A horizontal rotating shaft 18 is provided between the slide plate 5 and the flap 6, and the rotating shaft 18 passes through the two No. 1 circular sleeves 16 and the two No. 2 circular sleeves 17, and the rotating shaft 18 is fixedly connected to the two No. 2 circular sleeves 17. The torsion spring 7 is sleeved on the rotating shaft 18, and the torsion spring 7 is located between the two No. 2 circular sleeves 17. The two ends of the torsion spring 7 are respectively in conflict with the slide plate 5 and the flap 6. The number of the limit blocks 8 and the strip limit groove 9 are both two. The two limit blocks 8 are respectively fixedly connected to the two ends of the rotating shaft 18, and each limit block 8 is square. The two strip limit grooves 9 correspond to the two limit blocks 8, and each strip limit groove 9 is vertical.

[0050] When the limit block 8 slides out of the corresponding strip limit groove 9, the shaft 18 is not restricted. At this time, the flap 6 will be driven to rotate horizontally through the elastic force of the torsion spring 7. At this time, the flap 6 is perpendicular to the slide plate 5. When collecting feces samples, the flap 6 needs to be kept vertical. At this time, the rotating flap 6 is vertical. When the flap 6 rotates, it will drive the shaft 18 to rotate together. When the flap 6 is vertical, the limit blocks 8 at both ends of the shaft 18 are inserted into the corresponding strip limit grooves 9, so as to prevent the flap 6 from rotating by itself through the restriction of the strip limit grooves 9, and finally ensure When the square insert tube 1 is inserted downward into the feces, the flap 6 can always remain in a vertical state, wherein the slide plate 5 is inserted into the feces together with the square insert tube 1. Before the square insert tube 1 is pulled out, the slide plate 5 is slid downward so that the limit blocks 8 at both ends of the rotating shaft 18 slide out from the corresponding strip limit grooves 9, thereby driving the flap 6 to flip from vertical to horizontal through the torsion spring 7. Finally, when the square insert tube 1 is pulled out, the flap 6 rotating into the square insert tube 1 can block the lower end of the square insert tube 1 to prevent the feces entering the square insert tube 1 from leaking out from the lower end of the square insert tube 1.

[0051] In order to facilitate the disassembly and assembly of the torsion spring 7, the following features are provided:

[0052] A mounting block 19 is formed on each No. 2 circular sleeve 17, and two mounting grooves 20 are provided on the outer wall of the upper end of each flap 6. The two mounting blocks 19 are respectively fixed in the two mounting grooves 20. The two ends of the rotating shaft 18 pass through the two No. 2 circular sleeves 17 respectively. An annular boss 21 located between the two No. 2 circular sleeves 17 is formed in the middle of the rotating shaft 18. The two ends of the annular boss 21 are respectively in contact with the two No. 2 circular sleeves 17. The torsion spring 7 is sleeved on the annular boss 21. The parts of the two ends of the rotating shaft 18 close to the No. 2 circular sleeve 17 are both threaded. A screw cap 22 that is tightly pressed against the corresponding No. 2 circular sleeve 17 is screwed on each threaded portion of the rotating shaft 18. Each No. 1 circular sleeve 16 is provided with an elastic opening 23 along its axial direction for the end of the rotating shaft 18 to be inserted.

[0053] When installing the flap 6 to the lower end of the slide plate 5, first, the torsion spring 7 is sleeved on the annular boss 21, and then the two No. 2 circular sleeves 17 are respectively sleeved on the two ends of the rotating shaft 18. In this process, one side of each No. 2 circular sleeve 17 is in conflict with one end of the annular boss 21, and then the screw cap 22 is screwed into the threaded portion of the rotating shaft 18, and the rotating shaft 18 is fixedly connected to the two No. 2 circular sleeves 17 through the screw cap 22. When the rotating shaft 18 is fixed to the two No. 2 circular sleeves 17, each mounting block 19 is fixed in the corresponding mounting groove 20. At this time, the rotating shaft 18 is fixedly connected to the flap 6 through the two No. 2 circular sleeves 17, and finally, the two ends of the rotating shaft 18 are respectively inserted into the two No. 1 circular sleeves 16 through the elastic openings 23. The two ends of the rotating shaft 18 can rotate in the two No. 1 circular sleeves 16 respectively, so that the entire flap 6 can rotate with the rotating shaft 18 at the lower end of the slide plate 5.

[0054] In order to show that the slide plate 5 is slidably connected to the square cannula 1, the following features are provided:

[0055] Two strip-shaped limiting grooves 9 are formed on the outer wall of the square insert tube 1 with a strip-shaped opening 4, each notch 10 is close to the conical tube 2, and guide slides 24 are formed on both sides of the slide plate 5. The two guide slides 24 slide in the two strip-shaped limiting grooves 9 respectively, and an end plate 25 connected to the square insert tube 1 is formed on one end of the strip opening 4 close to the conical tube 2, and the end plate 25 covers the end of the strip opening 4 close to the conical tube 2, and the lower end of the end plate 25 is formed with an inclined surface 26 (such as Fig.12 As shown in FIG. 1 ), the slide plate 5 slides on the end plate 25 near one end of the tapered tube 2.

[0056] The slide plate 5 slides on the strip-shaped opening 4 through the guide strips 24 on both sides thereof. Figure 1As shown, the lower end of the square insert tube 1 exceeds the lower end of the slide plate 5, so as to ensure that after the slide plate 5 is lowered, the flip plate 6 flipped into the square insert tube 1 can block the lower end of the square insert tube 1. When the slide plate 5 is slid downward, the lower end of the slide plate 5 is lowered. At this time, the upper end of the strip opening 4 is closed by the end plate 25. When the square insert tube 1 is inverted, feces falls downward into the conical tube 2. At this time, the inclined surface 26 provided on the end plate 25 is used to ensure that the feces can slide down smoothly. Rubber pads (not shown in the figure) are provided between the end plate 25 and the slide plate 5 and between the guide slide bar 24 and the strip limit groove 9. The rubber pads are used to increase the sliding friction of the slide plate 5 to prevent the slide plate 5 from sliding downward by itself due to gravity.

[0057] To demonstrate the detailed structure of the lifting extrusion, the following features are set:

[0058] A strip-shaped groove 27 is provided on the outer wall of the slide plate 5, and the length direction of the strip-shaped groove 27 is parallel to the length direction of the slide plate 5. The slide block 11 slides in the strip-shaped groove 27. The flip arm 12 includes a rotating rod 28 and a support rod 29. One end of the rotating rod 28 is hinged to the slide block 11, and the support rod 29 is perpendicular to the rotating rod 28. The lifting and lowering extrusion component includes a push-pull rod 30 and a rubber plate 31. A limiting sleeve 32 is formed at one end of the support rod 29 away from the rotating rod 28. The axial direction of the limiting sleeve 32 is parallel to the sliding direction of the slide block 11. A rubber ring 33 is embedded in the limiting sleeve 32. The push-pull rod 30 coaxially passes through the rubber ring 33. The rubber plate 31 is fixed to one end of the push-pull rod 30. Two elastic plates 34 close to the conical tube 2 are provided on the outer wall of the slide plate 5. The rotating rod 28 can be stuck between the two elastic plates 34 after rotating to vertical.

[0059] When the feces is extracted, the lifting and extruding member does not work. At this time, the lifting and extruding member needs to be stored. The specific process is as follows: first slide the slider 11 upward to be close to the conical tube 2, then rotate the rotating rod 28 to be vertical, and then insert the vertical rotating rod 28 between the two elastic plates 34. The rotating rod 28 is clamped by the two elastic plates 34 to fix the rotating rod 28. Figure 1 The figure shows the state of the lifting and extruding member in the storage state. When feces enter the square insert tube 1, the square insert tube 1 is inverted. Thereafter, the feces in the square insert tube 1 needs to be pressed into the conical tube 2 through the flap 6. At this time, in order to better drive the flap 6 to press down, the slider 11 is slid close to the flap 6, and then the rotating rod 28 is rotated 180°. At this time, the rubber plate 31 provided on the push-pull rod 30 will be rotated into the square insert tube 1, and the rubber plate 31 will be located directly above the flap 6, as shown in FIG. Fig.16 and Fig.18As shown, the push-pull rod 30 is then pressed down to drive the flap 6 to be pressed down by the push-pull rod 30. When the flap 6 is pressed down to near the end plate 25, the flap 6 can no longer be pressed down. At this time, the flap 6 is first driven to be reset to the vertical position by the flap reset member. When the flap 6 is reset from the horizontal to the vertical position, the slider 11 is slid up, so that the rotating rod 28 avoids the reset of the flap 6. When the flap 6 is reset to the vertical position, the slider 11 is pressed (the slider 11 cannot slide at this time, otherwise it will cause the flap 6 to fall), and then the push-pull rod 30 is pressed down. Thereafter, the rubber plate 31 is driven by the push-pull rod 30 to slide toward the conical tube 2 in the direction insertion tube, and finally the remaining feces in the direction insertion tube is pressed out from the discharge nozzle 3 by the rubber plate 31. Among them, the material of the rubber plate 31 is hard rubber. After the rubber plate 31 enters the conical tube 2, the rubber plate 31 will be deformed, so the feces in the conical tube 2 can also be pressed out from the discharge nozzle 3 by the rubber plate 31.

[0060] In order to show how the slide pin 13 is mounted on the rotating frame, the following features are provided:

[0061] The rotating frame includes two symmetrical strip plates 35 (such as Fig. 20 As shown in the figure, one end of each strip plate 35 is hinged to the outer wall of the square insert tube 1, and each strip plate 35 is provided with a strip through groove 36, the length direction of the strip through groove 36 is translated with the length direction of the strip plate 35, the sliding pin 13 is arranged between the two strip plates 35, the axial direction of the sliding pin 13 is parallel to the length direction of the strip through groove 36, one end of the sliding pin 13 is fixed with a transverse pin 37, and the two ends of the transverse pin 37 pass through the two strip through grooves 36 respectively, the outer wall of the square insert tube 1 is formed with a second strip slide groove 38 corresponding to the through hole 14, the sealing slide cover 15 slides in the second strip slide groove 38, and the outer wall of the square insert tube 1 is fixed with an elastic buckle 39 close to the sliding pin 13.

[0062] When the sliding pin 13 is not in use, it is necessary to store the sliding pin 13. At this time, the two strip plates 35 need to be rotated, and the two strip plates 35 will drive the sliding pin 13 to rotate together. When the sliding pin 13 is rotated to a vertical position, one end of the sliding pin 13 will be stuck in the elastic buckle 39, such as Figure 4 As shown, the sliding pin 13 is fixed by the elastic buckle 39; when the sliding pin 13 is needed, the two strip plates 35 are rotated to be horizontal, and then the sliding pin 13 is slid. During this process, the horizontal sliding pin 13 will pass through the through hole 14 into the square insert 1, and finally the flap 6 that has been in a tilted state will be completely pushed to the vertical through the sliding pin 13.

[0063] In order to show the specific structure of the No. 1 conflict block, the following features are set:

[0064] The first abutment block includes four first protrusions 40 arranged in a matrix (eg Fig. 9As shown in FIG. 1 , each No. 1 protrusion 40 is formed on the inner wall of the lower end of the square insert 1, and two No. 2 protrusions 41 are formed on the side of the slide plate 5 facing the strip opening 4 in a symmetrical state, and the two No. 2 protrusions 41 are close to the flap 6 (as shown in FIG. Fig.15 as shown).

[0065] When the square cannula 1 is inserted into the feces, the slide plate 5 is slid downward, and then the limit block 8 will slide out of the strip limit groove 9, and the flap 6 will be immediately driven by the torsion spring 7 to flip into the square cannula 1. However, at this time, since the square cannula 1 contains feces, the flap 6 cannot be completely flipped to a horizontal state. Therefore, after the flap 6 rotates, it is necessary to continue to slide the slide plate 5 downward. The slide plate 5 will drive the flap 6 downward to collide with the four No. 1 protrusions 40. When the flap 6 conflicts with the four No. 1 protrusions 40, the flap 6 will gradually flip to a horizontal state, and finally the flap 6 will conflict with the two No. 2 protrusions 41 upward. Fig.15 As shown, the second protrusion 41 is used to ensure that the flap 6 remains horizontal and does not flip over excessively.

[0066] In order to show the specific structure of the second conflict block, the following features are set:

[0067] The second abutment block includes two symmetrical third protrusions 42 (such as Fig.10 As shown in the figure, each No. 3 protrusion 42 is formed on the inner wall of the square insert 1 near one end of the conical tube 2, and an elastic membrane 43 is provided between the flap 6 and the slide plate 5. The elastic membrane 43 is located on the side of the slide plate 5 and the flap 6 facing the strip opening 4. The two ends of the elastic membrane 43 are respectively fixedly connected to the flap 6 and the slide plate 5, and the elastic membrane 43 blocks the gap between the flap 6 and the slide plate 5.

[0068] When it is necessary to reset the horizontal flap 6 to a vertical position, first slide the slide plate 5 downward. When the flap 6 is pressed down to be close to the two No. 3 protrusions 42, the limit blocks 8 provided at both ends of the rotating shaft 18 will slide to the notch 10 on the strip limit groove 9. At this time, the flap 6 can rotate and is no longer restricted. When the flap 6 is pressed downward against the two No. 3 protrusions 42, the two No. 3 protrusions 42 will contact the free end of the flap 6. In this way, during the gradual descent of the flap 6, the flap 6 will gradually turn from horizontal to inclined. At the same time, the two strip plates 35 are turned horizontally and then slide. Sliding pin 13, during this process, the horizontal sliding pin 13 will penetrate into the square insert tube 1 through the through hole 14, and finally the flap 6 that has been in an inclined state will be completely pushed to the vertical through the sliding pin 13. When the flap 6 is rotated to be completely vertical, the limit blocks 8 at both ends of the rotating shaft 18 are aligned with the corresponding strip limit grooves 9, and then the limit blocks 8 are driven by the sliding slide 5 to slide into the strip limit grooves 9. Finally, the flap 6 will always remain in a vertical state. When the feces in the square insert tube 1 is pressed down, the elastic membrane 43 is used to prevent the feces from flowing out of the gap between the flap 6 and the slide 5.

[0069] Working principle:

[0070] In the initial state, the torsion spring 7 releases the elastic force to drive the flap 6 to rotate. At this time, the flap 6 will be horizontal and perpendicular to the slide plate 5. Before collecting feces from diseased livestock, the flap 6 is first flipped vertically, and then the slide plate 5 is slid to make the limit block 8 on the flap 6 insert into the strip limit groove 9. At this time, the torsion spring 7 is compressed by the flap 6 to generate elastic force, but the flap 6 will not be driven to rotate by the torsion spring 7 through the cooperation of the limit block 8 and the strip limit groove 9. Then the flap 6 will always remain in a vertical state. When collecting feces from diseased livestock, the conical tube 2 arranged on the square insert tube 1 is first facing upwards, and then the lower end of the entire square insert tube 1 is inserted into the feces. In this process, the lower end of the square insert tube 1, the lower end of the slide plate 5 and the flap 6 are all inserted into the feces. At this time, the feces will enter the square insert tube. When the sliding plate 5 is turned over by the torsion spring 7, the sliding plate 5 will be turned over to the square tube 1. However, at this time, the square tube 1 contains feces, and the flap 6 cannot be completely turned over to the horizontal position due to the resistance of the feces. Therefore, when the flap 6 is turned over, the sliding plate 5 continues to slide downward. The flap 6 in the inclined state will then contact with the first resistance block downward. Through the action of the first resistance block, the flap 6 is turned over to be close to the horizontal position. When the flap 6 contacts the first resistance block, the entire square tube 1 is pulled out upward. At this time, the inwardly turned flap 6 will block the lower end of the square tube 1, and the feces in the square tube 1 cannot be pulled out from the square tube 1. The lower end of the square cannula 1 leaks out. When the lower end of the square cannula 1 is pulled out from the feces, the sample tube is inserted into the discharge nozzle 3, and then the entire square cannula 1 is inverted. When the square cannula 1 is inverted, the slide plate 5 is slid downward, and the slide plate 5 will drive the flap 6 to descend. In this process, the limit block 8 is aligned with the strip limit groove 9 to ensure that when the slide plate 5 is lowered, the limit block 8 can slide into the strip limit groove 9. In this way, the flap 6 will always remain in a horizontal state during the descent process, and the feces in the square cannula 1 is pressed into the conical tube 2 through the flap 6. Finally, the feces falling into the conical tube 2 will be discharged into the sample tube through the discharge nozzle 3. When the flap 6 descends to near the second resistance block, the limit block 8 slides to the notch 10. Thereafter, the flap 6 is turned from horizontal to inclined through the resistance of the second resistance block. State, at the same time, slide the sealing slide cover 15 to open the through hole 14, rotate the sliding pin 13 to the horizontal through the rotating frame, and then insert the sliding pin 13 into the square insert tube 1, and drive the flap 6 to rotate to the vertical state through the resistance of the sliding pin 13. In this process, the flap 6 will compress the torsion spring 7. When the flap 6 rotates to the vertical state, slide the slide plate 5 to make the limit block 8 slide from the notch 10 into the strip limit groove 9. Finally, the flip will maintain the vertical state again. When the flap 6 is vertical, the lifting and extruding member is driven into the square insert tube 1 by the flip arm 12. Finally, the remaining feces in the square insert tube 1 is pressed into the sample tube by the lifting and extruding member, wherein the feces in the square insert tube 1 can be stored in multiple sample tubes. When the sample tube is full, the empty sample tube can be replaced.
