The surface of the reversing guard 6 is provided with anti-slip texture, and the inner wall of the reversing guard 6 is fixedly connected to the second rack 27 and the third rack 28. The second rack 27 and the third rack 28 are symmetrically distributed, and the second rack 27 and the third rack 28 have the same size.However, teeth are provided on the inner side of the second rack 27, while teeth are not provided on the third rack 28. The device can realize driving while realizing guiding activities through the other side by providing teeth on one side of the second rack 27 and the third rack 28. The anti-slip texture provided on the surface of the reversing guard 6 can improve the grip texture during the use of the device. A wire pulling sleeve 19, a wire pulling block 20, a first rack 21, a second gear 22, a collection jacket 23, and a second spring 24 are installed on the left side of the reversing guard 6. The second rack 27 is meshed and connected with the third gear 25. The third gear 25 is composed of a double gear distributed in parallel, and a locking frame 15 is installed above the third gear 25.

A wire hole 26 is provided above the locking frame 15. A belt 17 is provided above the third gear 25. Teeth are provided on the inner side of the belt 17. The left side of the belt 17 is meshed and connected with the first gear 18. The first gear 18 is meshed and connected with the sampling head 8. The sampling head 8 is rotatably connected with the extension tube 1, and a rubber sleeve 7 is provided at the connection between the sampling head 8 and the extension tube 1. When the collection jacket 23 needs to work, the trigger 5 is pulled, and the trigger 5 pulls the wire block 20 through the wire, and the wire block 20 drives the first rack 21 to move, and the first rack 21 is meshed with the second gear 22. The second gear 22 rotates, and the second gear 22 drives the left and right parts of the collection jacket 23 to move relative to each other. The clamping claw structure is closed to grab the sample to prevent the sample from falling during the collection and transfer process, and further avoid the sample from being contaminated. The second rack 27 and the third rack 28 are arranged on the inner side of the reversing guard 6. The inner wall of the extension tube 1 above the locking frame 15 is fixedly connected to a pair of guide rollers 16. The connection between the sampling head 8 and the extension tube 1 is engaged with the drawing sleeve 19. The drawing block 20 on the left side of the drawing sleeve 19 is bolted to the side of the first rack 21. The drawing wire is installed in the drawing block 20. The drawing wire passes through the drawing sleeve 19 and passes through the guide roller 16 on the left side of the locking frame 15 from the drawing sleeve 19. It passes through the wire hole 26 of the locking frame 15 and passes through the locking hole 26. The device passes the wire through the wire sleeve 19, passes through the wire sleeve 19, passes through the guide roller 16 on the left side of the locking frame 15, passes through the wire hole 26 of the locking frame 15, and passes through the wire hole 26 to the right side of the locking frame 15, until it is sleeved in the wire hole 14 on the left side of the perpendicular bisector of the wire hole 14 to form a triangular traction line. After the wire is stressed, under the action of the guide roller 16, the cable is triangular as a whole, or is straightened, thereby pulling the locking frame 15 upward, and the pulled locking frame 15 will jam the third gear 25, so that the sampling head 8 cannot be deflected, thereby improving the sampling accuracy of the equipment.The first rack 21 is configured as a rack structure, and the first rack 21 is meshed with the second gear 22, and the second gear 22 is meshed with the collection jacket 23. The collection jacket 23 is divided into two parts, the left part of the collection jacket 23 is a clamping claw structure, and the right side of the collection jacket 23 is a double-sided rack structure. The first protective cover 9 and the second protective cover 10 are hinged on the left side of the sampling head 8, and the first protective cover 9 and the second protective cover 10 are fixedly connected to the right side of the second spring 24, and a circular hole is provided at the center of the first protective cover 9 and the second protective cover 10. The first protective cover 9 and the second protective cover 10 are made of transparent antibacterial plastic material. The first protective cover 9 and the second protective cover 10 are made of transparent antibacterial plastic material, which protects the sample from contamination while facilitating the staff to observe the sampling process. When no sampling is performed, the first protective cover 9 and the second protective cover 10 are in a closed state under the elastic force of the second spring 24, protecting the sampling head 8 from contamination. When the sampling head 8 contacts the animal for sampling, the protective cover is squeezed open. After the sampling is completed, it automatically closes under the action of the second spring 24, isolating the collected sample from the outside world, effectively preventing the sample from being contaminated during subsequent operations.

[0049] Working principle: When using a sampling device for animal epidemic prevention and random inspection to prevent pollution, if you want to open the storage cover 2, push the trigger 5 forward. At this time, the pull wire connected to the trigger 5 pulls the limit pin 13, so that the limit pin 13 overcomes the elastic force of the first spring 12 and moves to the right, unlocking the storage cover 2, and then the storage cover 2 can be opened, and the required collection equipment, such as sampling cotton swabs, can be taken out from the storage tray 3. After taking out the equipment, release the trigger 5, the first spring 12 recovers its deformation, pushes the limit pin 13 to move to the left, reinserts it into the small hole of the storage cover 2, and locks the storage cover 2.

[0050] When sampling is required, the position of the sampling head 8 is adjusted according to the position of the animal by sliding the reversing guard 6 in the guide groove 11. The movement of the reversing guard 6 drives the second rack 27 and the third rack 28 to move, and since the second rack 27 is meshed with the third gear 25, the third gear 25 rotates accordingly. When the third gear 25 rotates, it drives the belt 17 mounted on it to rotate, and the belt 17 drives the first gear 18 to rotate, so that the sampling head 8 rotates to sample the animal.

[0051] During the sampling process, if it is necessary to grab a sample, the trigger 5 is pulled again. The trigger 5 pulls the pull-wire block 20 through the pull wire, and the pull-wire block 20 drives the first rack 21 to move, and the first rack 21 meshes with the second gear 22, so that the second gear 22 rotates, and the second gear 22 drives the collection jacket 23 to be pushed outward, and pushes open the first protective cover 9 and the second protective cover 10, and the collection jacket 23 pushes out the disposable sampling cotton swab to grab and dip the sample.

[0052] After the sampling is completed, the first protective cover 9 and the second protective cover 10 are automatically closed under the elastic force of the second spring 24, isolating the collected sample from the outside world to prevent the sample from being contaminated. At this time, the collected sample can be placed in a corresponding sample storage container for subsequent processing.

[0053] During the entire operation process, the rubber sleeve 7 can increase the comfort of hand holding and prevent the hand from slipping; the design of the guide roller 16 and the wire hole 26 ensures the smooth movement of the pull wire inside the device, avoids the pull wire from being entangled or stuck, and ensures that all components of the device can work normally. At the same time, when the pull wire is subjected to force under the action of the guide roller 16, the cable is triangular as a whole, or is straightened, thereby pulling the locking frame 15 upward. The pulled locking frame 15 will jam the third gear 25, making the sampling head 8 unable to deflect, thereby improving the accuracy of the equipment sampling.

[0054] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
