[0026] In order to enable those skilled in the art in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0027] Since most current sampling clips adopt the form of clamping an object when a force is applied to the handle, during sampling, the sampling personnel need to continuously apply a force to clamp the gauze. Long-term sampling will increase the labor intensity of the sampling personnel, make the sampling personnel feel tired, and affect the sampling efficiency. However, the auxiliary sampling tool provided by the present invention adopts the form of loosening the object when a force is applied and clamping the object when no force is applied. During sampling, the sampling personnel do not need to apply a force to clamp the gauze, which can reduce the labor intensity of the sampling personnel and will not feel tired even during long-term sampling, and can effectively improve the sampling efficiency. The auxiliary sampling tool provided by the present invention is as follows:

[0028] Please refer to together Figures 1 to 3, the present utility model provides an auxiliary sampling tool, mainly used for regularly sampling and detecting the pigsty environment. The auxiliary sampling tool includes a clamping assembly 10, a handle assembly 30, and a connecting assembly 20. The clamping assembly 10 includes a fixing member 11 and two clamping jaws 12. The two clamping jaws 12 are fixedly installed on the fixing member 11. The two clamping jaws 12 are arranged oppositely. A clamping portion 121 is provided on the clamping jaws 12. The two clamping jaws 12 can approach each other to clamp an object or move away from each other to clamp or release the object; the handle assembly 30 is configured to drive the two clamping jaws 12 to move away from each other to release the object when a force is applied, and drive the two clamping jaws 12 to approach each other to clamp the object when no force is applied; the connecting assembly 20 is used to connect the handle assembly 30 and the clamping assembly 10.

[0029] Please refer to Figures 1 to 3 , in the auxiliary sampling tool provided by the present utility model, the clamping assembly 10 further includes a first pin shaft 13. The two clamping jaws 12 can rotate around the first pin shaft 13 so that the two clamping jaws 12 move away from each other or approach each other.

[0030] Specifically, a movable hole 122 is provided on the clamping jaw 12. The first pin shaft 13 passes through the movable holes 122 on the two clamping jaws 12. The two clamping jaws 12 can rotate around the first pin shaft 13 so that the two clamping jaws 12 move away from each other or approach each other. In this embodiment, the movable hole 122 is a kidney-shaped hole. In other embodiments, the movable hole 122 can be strip-shaped, and no specific limitation is made.

[0031] Please refer to Figures 1 to 3 , the connecting assembly 20 includes a connecting member 21 and a connecting rope 22. The connecting assembly 20 is used to connect the clamping assembly 10 and the handle assembly 30 together. A cavity 211 is formed inside the connecting member 21. The two ends of the connecting member 21 are respectively connected to the handle assembly 30 and the fixing member 11. Specifically, in this embodiment, the connecting member 21 is a straight tubular structure; the connecting rope 22 is accommodated in the cavity 211 of the connecting member 21. The two ends of the connecting rope 22 respectively extend out from the two ends of the connecting member 21. The two ends of the connecting rope 22 are respectively connected to the first pin shaft 13 and the handle assembly 30 in the clamping assembly 10. In this embodiment, the connecting rope 22 can be made of steel wire rope, etc.

[0032] Please refer to Figures 1 to 3, the auxiliary sampling tool provided by the present utility model further includes a reset assembly 40. The reset assembly 40 includes a reset spring 41 and a pushing member 42. Both the reset spring 41 and the pushing member 42 are arranged inside the fixing member 11. The pushing member 42 is provided with a through hole (not marked in the figure) along the axis. The cross-section of the pushing member 42 is generally in a "convex" shape. The pushing member 42 abuts against the end of the clamping jaw 12 away from the clamping portion 121. The reset spring 41 abuts against the pushing member 42 and the inner wall surface of the fixing member 11 respectively. Through the pushing member 42, the clamping jaw 12 and the reset spring 41 can exert forces on each other. In other embodiments, the pushing member 42 can be cylindrical, prismatic, frustum-shaped, etc., as long as it can exert forces on the clamping jaw 12 and the reset spring 41 on each other, and no specific limitation is made.

[0033] One end of the connecting rope 22 is connected to the release handle 32, and the other end of the connecting rope 22 passes through the pushing member 42 through the through hole and is connected to the first pin shaft 13. When the sampling personnel apply a force to the release handle 32 to make the release handle 32 rotate, the connecting rope 22 can drive the first pin shaft 13 to move along the movable hole 122, so that the clamping jaw 12 rotates relative to the first pin shaft 13, driving the two clamping jaws 12 to move away from and / or close to each other.

[0034] Please refer to Figures 1 to 3 , the handle assembly 30 includes a fixed handle 31, a release handle 32 and a second pin shaft 33. The fixed handle 31 is fixedly connected to the fixing member 11. The release handle 32 is configured to be able to rotate relative to the fixed handle 31 along the second pin shaft 33. When a force is applied during use, the release handle 32 can be driven to rotate relative to the fixed handle 31. The release handle 32 drives the two clamping jaws 12 in the clamping assembly 10 to move away from each other to loosen the item through the connecting rope 22.

[0035] The handle assembly 30 further includes a clamping spring 34. The clamping spring 34 is arranged inside the fixed handle 31. The two ends of the clamping spring 34 respectively abut against the release handle 32 and the inner wall of the fixed handle 31. When the release handle 32 rotates relative to the fixed handle 31, the release handle 32 can compress the clamping spring 34. When the sampling personnel apply a force to the release handle 32, the release handle 32 rotates relative to the fixed handle 31 around the second pin shaft 33, and the release handle 32 compresses the clamping spring 34 when rotating.

[0036] In this embodiment, the elastic coefficient of the clamping spring 34 is greater than that of the reset spring 41, so that the elastic force of the clamping spring 34 is greater than that of the reset spring 41. Through such a setting, it can be ensured that the auxiliary sampling tool has a large enough clamping force to ensure that the two clamping jaws 12 in the clamping assembly 10 can clamp the item and prevent the item from falling during the clamping process.

[0037] The working principle of the auxiliary sampling tool provided by the present utility model is as follows: When not in use, the two jaws 12 of the auxiliary sampling tool are in a clamped state. When sampling and detecting the pigsty environment, the sampling personnel hold the handle assembly 30, and apply force with their hands to the release handle 32. The release handle 32 rotates around the second pin shaft 33 relative to the fixed handle 31 under the action of the force. One end of the release handle 32 connected to the connecting rope 22 approaches one end of the jaws 12. The release handle 32 rotates to compress the clamping spring 34, and the connecting rope 22 is in a relaxed state. The two jaws 12 in the clamping assembly 10 move away from each other and open, and the gauze is placed at the jaws 12, and the two jaws 12 clamp the gauze.

[0038] After the jaws 12 clamp the gauze, the sampling personnel stop applying force to the release handle 32. The clamping spring 34 resets under its own elastic force. Since the clamping spring 34 abuts against the handle, the clamping spring 34 pushes the end of the release handle 32 connected to the connecting rope 22 to rotate away from the jaws 12, thereby tightening the connecting rope 22. One end of the connecting rope 22 connected to the first pin shaft 13 pulls the first pin shaft 13 to move towards the fixed handle 31, and the first pin shaft 13 moves along the movable hole 122 on the jaws 12, thereby driving the two jaws 12 to approach each other and clamp the gauze.

[0039] Since most of the current sampling clips adopt the form of clamping an object when applying force to the handle, when sampling, the sampling personnel need to continuously apply force to clamp the gauze. Long-term sampling will increase the labor intensity of the sampling personnel, make the sampling personnel feel tired, and affect the sampling efficiency. However, the auxiliary sampling tool provided by the present utility model adopts the form of loosening the object when applying force and clamping the object when not applying force. When sampling, the sampling personnel do not need to apply force to clamp the gauze, which can reduce the labor intensity of the sampling personnel, and will not feel tired during long-term sampling, and can effectively improve the sampling efficiency.

[0040] It should be noted that in this specification, relational terms such as first and second are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0041] Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the present utility model.
