Description

Technical Field

[0001] This utility model relates to the field of sampling technology, and in particular to a sampling tool. Background Technology

[0002] Whether in animal husbandry or basic research, feces are an important analytical sample for scientific research. In vitro fecal sample collection typically employs methods such as scooping with a spatula, picking with a toothpick, or dipping with a cotton swab. However, when sampling characteristic fecal samples in small quantities or with abnormally wet and sticky fecal samples, it is difficult to use the conventional spatula sampling method. While toothpicks and cotton swabs can be used, they often result in small, incomplete samples, easily leading to biased results. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application provides a sampling tool.

[0004] This application provides a sampling tool that employs the following technical solution:

[0005] A sampling tool includes two clamping bodies hinged together by a hinge shaft. One end of each clamping body is provided with a clamping head, and the other end is a clamping handle. A sample clamping piece is provided on the clamping head via a connecting component. A connecting seat is provided on the clamping head. One end of the sample clamping piece has an installation hole, and the connecting seat is installed in the installation hole. The connecting seat is provided with a connecting component for connecting to the sample clamping piece. The clamping body is provided with an adjustment component for adjusting its own length, and the clamping handle is provided with a fixing component.

[0006] By adopting the above technical solution, the staff fixes the sample clips to the connecting seat using the connecting component, then adjusts the length of the clamp body using the adjusting component. The staff then inserts their fingers into the clamp handles, positioning the two sample clips on either side of the sample to be sampled. The clamp body is then controlled to move the two sample clips closer together, making it easier to pick up small amounts of wet and sticky fecal samples and place them on top of the sample clips. After sampling, the two clamp handles are fixed together using the fixing component, ensuring the sample is stably placed on the sample clips. The sample is then transferred to a sample bag or sampling tube. The connection between the sample clips and the connecting seat is loosened using the connecting component, facilitating the separation of the sample clips from the clamp.

[0007] Optionally, the connecting assembly includes a drive seat, a first connecting rod, and a second connecting rod. The drive seat has a mounting through hole along its length. A first limiting rod and a second limiting rod are hinged to one end of the drive seat away from the chuck. A drive screw is rotatably mounted in the mounting through hole. The drive seat and the drive screw are threadedly connected. One end of the first connecting rod is hinged to the top of the drive seat and the other end is hinged to the first limiting rod. One end of the second connecting rod is hinged to the bottom of the drive seat and the other end is hinged to the second limiting rod. A limiting groove is formed on the inner wall of the mounting hole. A drive motor is embedded inside the chuck. The output shaft of the drive motor is coaxially connected to the drive screw. A battery is embedded in the chuck.

[0008] By adopting the above technical solution, after the staff slides the connector into the mounting hole, the battery powers the drive motor, which in turn drives the drive screw to move the drive seat, so that one end of the first limit rod and the second limit rod are inserted into the limit groove, thereby allowing the sample clip to be stably installed on the connector.

[0009] Optionally, the adjustment assembly includes an adjustment cylinder, one end of which is connected to a clamping body. An adjustment rod is slidably disposed inside the adjustment cylinder. The end of the adjustment rod away from the adjustment cylinder is connected to a clamping handle. A fixing pin is provided on the adjustment cylinder. A spring is sleeved on the fixing pin. The other end of the spring is connected to the adjustment cylinder. Multiple limiting holes are evenly opened on the adjustment rod along its own length direction. The bottom of the fixing pin is inserted into the limiting holes.

[0010] By adopting the above technical solution, the adjusting rod is slid along the length of the adjusting cylinder to adjust the overall length of the clamp. When it is moved to the appropriate position, the operator releases the fixing pin, thereby driving the bottom of the fixing pin to insert into the limiting hole corresponding to the current position.

[0011] Optionally, the fixing component includes a fixing plate and a mounting plate. One end of the fixing plate is connected to one of the clamps, and one end of the mounting plate is hinged to the other clamp. A permanent magnet is provided on the mounting plate, and the permanent magnet is magnetically fixed to the fixing plate.

[0012] By adopting the above technical solution, when taking samples, the mounting plate is moved onto the fixing plate with a finger, making it difficult for the two clamps to separate.

[0013] Optionally, there is an angle between the clamp and the sample clamp, the angle being 90 degrees to 150 degrees, and the bottom of the sample clamp is in contact with the ground.

[0014] By adopting the above technical solution, the clamp is tilted when the staff holds the clamp, so that there is an angle between the clamp head and the sample clamp, and the bottom of the sample clamp can be in contact with the ground.

[0015] Optionally, the clamp has a mounting groove, the battery is installed in the mounting groove, and a cover plate is provided on the mounting groove, the cover plate being engaged with the clamp.

[0016] By adopting the above technical solution, the battery can be replaced conveniently and quickly.

[0017] Optionally, a flexible protective sleeve is provided on the clamp handle.

[0018] By adopting the above technical solutions, the hands of the staff can be protected to a certain extent.

[0019] Optionally, a switch button is provided on one end of the adjusting rod near the clamp, and the switch button is connected to the battery and the drive motor respectively via wires.

[0020] By adopting the above technical solution and installing a switch button on the clamp, the operator can adjust the forward and reverse rotation of the drive motor.

[0021] This utility model has the following advantages:

[0022] 1. By setting up connecting components and fixing components, the sample clip can be fixedly installed on the connecting seat. After sampling is completed, the two clamps are fixed to each other by the fixing components, so that the sample can be stably placed on the sample clip, so that the staff can transfer the sample.

[0023] 2. By setting adjustment components, the overall length of the clamp can be adjusted to adapt to various clamping requirements;

[0024] 3. By setting a switch button, the forward and reverse rotation of the drive motor can be easily adjusted. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0032] like Figures 1 to 5As shown, a sampling tool includes two clamping bodies 1 hinged together by a hinge shaft. One end of each clamping body 1 has a clamp head 11, and the other end has a handle 12. A sample clamping piece 13 is mounted on the clamp head 11 via a connecting assembly 2. A connecting seat 14 is also mounted on the clamp head 11. One end of the sample clamping piece 13 has a mounting hole 15, and the connecting seat 14 is installed within the mounting hole 15. The size of the connecting seat 14 is smaller than the size of the mounting hole 15, thus creating a certain gap between the connecting seat 14 and the wall of the mounting hole 15. A connecting assembly 2 is mounted on the connecting seat 14 for easy connection with the sample clamping piece 13. An adjusting assembly 3 is mounted on the clamping body 1 for adjusting its own length. A fixing assembly 4 is mounted on the handle 12 for fixing it to the other handle 12. In use, the operator places the sample clamping piece 13 onto the connecting seat 14, then fixes the sample clamping piece 13 to the connecting seat 14 via the connecting assembly 2, and then adjusts the clamping body 1 using the adjusting assembly 3. The length is adjusted to facilitate clamping and operation by the operator. The operator places their fingers inside the clamp handle 12 and controls the clamp body 1 and sample clamp pieces 13, positioning the two sample clamp pieces 13 on either side of the sample to be sampled. Then, by controlling the clamp body 1, the two sample clamp pieces 13 are moved closer to each other, making it easier to clamp small amounts of fecal samples and wet, sticky fecal samples to the top of the sample clamp pieces 13. After sampling, the two clamp handles 12 are fixed together by the fixing component 4, making it difficult for the two clamp handles 12 to separate, and thus also making it difficult for the two sample clamp pieces 13 to separate, allowing the sample to be stably placed on the sample clamp pieces 13. The sample is then transferred to a sample bag or sampling tube. The connection between the sample clamp piece 13 and the connecting seat 14 is loosened by the connecting component 2, allowing the connecting seat 14 to slide freely within the mounting hole 15, thus facilitating the separation of the sample clamp piece 13 from the clamp head 11. By replacing the sample clamp piece 13, it is convenient to sample different samples.

[0033] like Figures 1 to 5As shown, the connecting assembly 2 includes a drive seat 21, a first connecting rod 22, and a second connecting rod 23. A mounting through hole 24 is formed on the connecting seat 14 along its length. A first limiting rod 25 and a second limiting rod 26 are hinged to one end of the connecting seat 14 away from the chuck 11. A drive screw 27 is rotatably installed within the mounting through hole 24. The length of the drive screw 27 is consistent with the length direction of the mounting through hole 24. The drive seat 21 is threadedly connected to the drive screw 27. One end of the first connecting rod 22 is hinged to the top of the drive seat 21, and the other end is hinged to the first limiting rod. 25. The second connecting rod 23 is hinged at one end to the bottom of the drive seat 21 and at the other end to the second limiting rod 26. A limiting groove 28 is provided on the inner wall of the mounting hole 15. A drive motor 29 is embedded inside the chuck 11. The output shaft of the drive motor 29 is coaxially connected to the drive screw 27. A battery is embedded in the chuck 11. In use, when the operator slides the connecting seat 14 into the mounting hole 15, the battery supplies power to the drive motor 29. When the drive motor 29 rotates, it drives the drive screw 27 to rotate synchronously through the output shaft. During rotation, the drive seat 21 will move synchronously. The movement of the drive seat 21 will then drive the first connecting rod 22 and the second connecting rod 23 to move synchronously. As the first connecting rod 22 moves, it will push the first limiting rod 25 to rotate around the end furthest from the drive seat 21, causing the end of the first limiting rod 25 connected to the first connecting rod 22 to extend out of the mounting through hole 24 and insert into the limiting groove 28. Similarly, as the second connecting rod 23 moves, it will push the second limiting rod 26 to rotate around the end furthest from the drive seat 21, causing the second limiting rod 26 to rotate around the end furthest from the drive seat 21. One end of the rod 23 extends out of the mounting through hole 24 and is also inserted into the limiting groove 28, so that the sample clip 13 can be stably installed on the connecting seat 14. When the sample clip 13 is used to take a sample, the sample and the sample clip 13 are put into a sample bag or sampling tube. Then, the drive motor 29 is driven to rotate in the opposite direction, so that the drive seat 21 rotates in the opposite direction, so that the first limiting rod 25 and the second limiting rod 26 are stored in the mounting through hole 24, so that the sample clip 13 can slide freely along the connecting seat 14 and be easily separated from each other.

[0034] like Figures 1 to 5As shown, the adjustment assembly 3 includes an adjustment cylinder 31, one end of which is connected to the clamp 1. An adjustment rod 32 is slidably installed inside the adjustment cylinder 31. The end of the adjustment rod 32 away from the adjustment cylinder 31 is connected to the clamp handle 12. A fixing pin 33 is installed on the adjustment cylinder 31, and a spring 34 is sleeved on the fixing pin 33. The other end of the spring 34 is connected to the adjustment cylinder 31. Multiple limiting holes 35 are evenly opened along the length direction of the adjustment rod 32, and the bottom of the fixing pin 33 is inserted into the limiting holes 35. When it is necessary to adjust the length of the clamp 1 itself... The worker holds the fixing pin 33 and pulls it away from the limiting hole 35. The spring 34 is stretched. At this time, the adjusting rod 32 slides along the length of the adjusting cylinder 31 to adjust the overall length of the clamp 1. When it moves to the appropriate position, the worker releases the fixing pin 33, and the spring 34 moves back to its original length, thereby driving the bottom of the fixing pin 33 to insert into the limiting hole 35 corresponding to the current position, thereby limiting and fixing the adjusting rod 32 and improving the stability during the working process.

[0035] like Figures 1 to 5 As shown, the fixing component 4 includes a fixing plate 41 and a mounting plate 42. One end of the fixing plate 41 is connected to one of the clamping handles 12, and one end of the mounting plate 42 is hinged to the other clamping handle 12. A permanent magnet 43 is mounted on the mounting plate 42, and the permanent magnet 43 is magnetically attracted and fixed to the fixing plate 41. In use, the operator holds the clamping handles 12 and drives the two clamping handles 12 to move towards each other, thereby driving the two sample clamping plates 13 to move towards each other. When the sample collection is completed, the operator uses their fingers to push the mounting plate 42 onto the fixing plate 41, making it difficult for the two clamping handles 12 to separate. Thus, during the process of the operator transferring the sample to the sample bag or sampling tube, the two sample clamping plates 13 are not easy to separate and prevent the sample from spilling, thereby improving the stability during use.

[0036] like Figures 1 to 5 As shown, there is an angle between the clamp 11 and the sample clamp 13, which is 90 degrees to 150 degrees. The bottom of the sample clamp 13 is in contact with the ground. During use, by making an angle between the clamp 11 and the sample clamp 13, the clamp 1 can be tilted while the operator holds the clamp 1, and the bottom of the sample clamp 13 can be in contact with the ground. This makes it easier to clamp small amounts of fecal samples and abnormally wet and sticky fecal samples. In this embodiment, the angle between the sample clamp 13 and the clamp 11 is 120 degrees.

[0037] like Figures 1 to 5As shown, the clamp 11 has an installation groove 5, and the battery is installed in the installation groove 5. The installation groove 5 is provided with a cover plate 51, which is snapped into the clamp 11. When in use, when the battery power is too low, the cover plate 51 is removed, the old battery is removed, the new battery is inserted, and then the cover plate 51 is reinstalled, so as to conveniently and quickly replace the battery.

[0038] like Figures 1 to 5 As shown, a flexible protective sleeve 52 is installed on the handle 12. During use, by installing the flexible protective sleeve 52 on the handle 12, the gripping feel of the staff can be improved, and the staff's hands can be protected to a certain extent.

[0039] like Figures 1 to 5 As shown, a switch button 53 is installed on one end of the adjusting rod 32 near the clamp 12. The switch button 53 is connected to the battery and the drive motor 29 respectively via wires. Since the switch button 53 is existing technology, the specific composition of the switch button 53 will not be described in detail in this embodiment. By installing the switch button 53 on the clamp 1, the operator can adjust the start and stop of the drive motor 29 and the forward and reverse rotation of the motor through the switch button 53.

[0040] The implementation principle of this embodiment is as follows: The operator fixes the sample clip 13 to the connecting seat 14 through the connecting component 2, and then adjusts the length of the clamp body 1 through the adjusting component 3. Then, the operator puts his / her fingers into the clamp handle 12 so that the two sample clips 13 are located on both sides of the sample to be sampled. Then, the operator controls the clamp body 1 to drive the two sample clips 13 to move towards each other, so as to facilitate the clamping of small amounts of fecal samples and wet and sticky fecal samples to the top of the sample clip 13. After the sampling is completed, the two clamp handles 12 are fixed to each other through the fixing component 4 so that the sample can be stably placed on the sample clip 13. Then, the sample is transferred to the sample bag or sampling tube. The connection between the sample clip 13 and the connecting seat 14 is loosened by the connecting component 2, so as to facilitate the separation of the sample clip 13 from the clamp head 11.

[0041] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model.
