At the same time, the rubber material is soft, which can reduce the harm to the animal's oral cavity, avoid discomfort or injury during sampling. When sampling oral fluid, by moving the top guard, part of the field of vision can be blocked, reducing the animal's perception of the external environment, alleviating its nervousness, thereby reducing the stress response and making the animal more cooperative during sampling. At the same time, the use of the top guard can reduce the need for additional fixation of the animal, simplify the operation steps, and save time and manpower.

[0015] (2) In this invention, by moving the clamping rod, the movement of the animal's head can be effectively controlled, preventing it from struggling or swinging, ensuring the smooth progress of the sampling process. At the same time, after the head is fixed, the operator can use the sampling device more precisely, reducing the operation time and improving the efficiency. After the animal is fixed, by moving the collection drawer, the collection drawer can be pushed out to accurately collect oral fluid, avoiding sample contamination or omission caused by the movement of the animal, improving the detection accuracy. At the same time, after fixing the animal, the operator can focus more on sampling without being distracted by controlling the animal, thereby improving the efficiency.

[0016] (3) In this invention, the process of gradually pushing out and opening the collection drawer is smoother, avoiding sudden movements that may startle the animal and reducing its stress response. At the same time, the operation of pushing out and opening the collection drawer is more orderly, reducing the possibility of operation errors and repeated sampling, and improving the overall efficiency.

[0017] (4) In this invention, the contact between the inclined plane rod and the limiting block restricts the collection box, ensuring that the sampling device remains stable during the operation process next time, avoiding sampling errors caused by shaking or deviation. At the same time, preventing the excessive movement of the collection box can reduce the risk of accidental collisions or equipment damage during the operation process, protecting the safety of the operator and the animal.

By moving the clamping rod 128, the movement of the animal's head can be effectively controlled, preventing it from struggling or swinging, ensuring the smooth progress of the sampling process. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reducing the operation time and improving the efficiency.

[0025] The stabilizing device also includes a push rod 129, an elastic telescopic rod 1210, a collecting drawer 1211 and an inclined block 1212.

The movement of the clamping rod 128 can effectively control the movement of the animal's head, prevent it from struggling or swinging, and ensure the smooth progress of the sampling process. At the same time, after the head is fixed, the operator can use the sampling device more accurately, reduce the operation time, and improve the efficiency. While the clamping rod 128 is moving, it drives the push rod 129 to start moving. The movement of the push rod 129 contacts and pushes the first inclined plane block 1212 to start moving. The movement of the first inclined plane block 1212 drives the collection drawer 1211 to start moving forward. After the animal is fixed and the collection drawer 1211 moves, pushing out the collection drawer 1211 can accurately collect oral fluid, avoid sample contamination or omission caused by the movement of the animal, improve the detection accuracy. At the same time, after the animal is fixed, the operator can focus more on sampling without being distracted to control the animal, thereby improving the efficiency.

[0031] While the collection drawer 1211 moves, it drives the baffle 134 to start moving. The movement of the baffle 134 drives the fixed block 135 to start moving. The movement of the fixed block 135 contacts the second inclined block 132 and pushes the baffle 134 to move towards the limiting plate 133. The movement of the baffle 134 opens the collection drawer 1211. The process of gradually pushing out and opening the collection drawer 1211 is smoother, avoiding sudden movements that may startle the animal and reducing its stress response. At the same time, the operation of pushing out and opening the collection drawer 1211 is more orderly, reducing the possibility of operation errors and repeated sampling, and improving the overall efficiency. After collection, the baffle 134 completely shields the collection drawer 1211. At this time, the staff manually presses the button 138. The button 138 contacts and pushes the inclined rod 139 to start moving downward. The inclined rod 139 moves away from the contact with the limiting block 1310. Subsequently, the staff manually pulls the handle 137 to pull out the collection box 136 from the inside of the collection drawer 1211. After pulling out, the staff can take out the oral liquid from the collection box 136 for testing. After cleaning the collection box 136, it is put back into the collection drawer 1211. At this time, the inclined rod 139 contacts the limiting block 1310 to limit the collection box 136, ensuring that the sampling device remains stable during the next operation, avoiding sampling errors caused by shaking or deviation, and at the same time preventing excessive movement of the collection box 136, which can reduce the risk of accidental collisions or equipment damage during the operation and protect the safety of the operator and the animal.
