At the same time, appropriate limitation and fixation can make the animal feel safer. Compared with the completely free state, the fixed posture can reduce unnecessary movement, reduce adverse reactions such as rapid heartbeat and body temperature rise caused by stress, and move into the driving plate 9 by moving the telescopic plate 14, preventing the telescopic plate 14 from blocking the movement of the limiting plate 166, so that the limiting plate 166 cannot limit the animal firmly enough.

[0026] The surface of the push rod 167 and the inclined block one 164 in contact with each other is provided with an inclined surface. The limiting plate 166 is in contact with the inner wall of the epidemic prevention room 1. By arranging the inclined surface, it is ensured that the push rod 167 can smoothly push the inclined block one 164 during movement. By contacting, it is ensured that the limiting plate 166 can not occupy the internal space of the epidemic prevention room 1.

[0027] A sliding groove is formed in the top of the fixed plate 161. The inclined block one 164 is in contact with the fixed plate 161.

When the driving plate 9 moves, the rotating rod 10 starts to move, the rotating rod 10 moves to drive the gear 11 to start to move, the gear 11 moves to contact the rack 12, then the gear 11 starts to rotate under the continuous movement, the rotating rod 10 starts to rotate under the rotation of the gear 11, the rotating rod 10 rotates to drive the transmission belt one 13 to start to rotate around the rotating rod 10, the transmission belt one 13 rotates to drive the telescopic plate 14 to start to move, the telescopic plate 14 moves into the driving plate 9, to prevent the telescopic plate 14 from blocking the movement of the limiting plate 166, to cause the limiting plate 166 to be not firm enough in limiting the animal.

[0032] When the limiting plate 166 moves, the top rod 171 starts to move, and the top rod 171 moves away from the contact with the inclined block two 175. Then, the sliding plate 173 starts to move under the driving of the movable end of the elastic telescopic rod 174, and the sliding plate 173 moves to open the ventilation opening on the roof 3. The air quality in the experimental environment can be improved, the air is fresh, the stress reaction of the animals is reduced, the pressure of the animals is reduced, the animals are more calm to accept the experimental operation, and a better working environment for the experimental personnel to perform the inspection, sampling or treatment operation is ensured.
