After the opening is completed, the rotating plate 6 is driven to rotate under the torsion of the torsion spring 7, so that the rotating plate 6 protrudes from the inside of the rotating groove 5. At this time, the rotating plate 6 is in contact with the inner wall of the rotating groove 5 and cannot continue to rotate. The upper end of the rotating plate 6 is inserted into the gap between the teeth of the animal. When the animal breaks free during the oral inspection and causes the opener to detach, the teeth in the mouth will apply force to the rotating plate 6 to push the rotating plate 6 to rotate further. At this time, the rotating groove 5 blocks the rotating plate 6 from continuing to rotate, thereby blocking the opener from detaching from the animal's mouth, making the installation of the opener more secure. A handle 8 is provided at the lower end of the U-shaped frame 1 for convenient grasping of the entire device. The handle 8 is an externally threaded tube handle. A swivel 9 is threadedly connected to the outer arc surface of the handle 8. A connecting plate 10 is rotatably connected in a rotating groove on the outer arc surface of the swivel 9. The lower ends of the guide columns 3 are fixedly connected to the connecting plate 10. The swivel 9 is rotated, and the swivel 9 and the connecting plate 10 are relatively rotated. The swivel 9 is threadedly connected to the handle 8, which drives the guide column 3 and the upper support plate 4 to move upward. The upper end of the handle 8 is vertically slidably connected to a rectangular plate 11. A limit plate 12 is provided at the upper end of the rectangular plate 11. The limit plate 12 is V-shaped The lower end of the rectangular plate 11 is provided with a sleeve 13, and the lower end of the handle 8 is rotatably connected with a screw 14, which is threadedly connected to the lower end of the sleeve 13.

[0022] The working principle of an animal oral dilator for veterinary use in animal husbandry provided by the present utility model is as follows: During the process of animal husbandry, when a veterinarian needs to examine an animal's oral cavity, move the upper support plate 4 and the lower support plate 2 into the animal's oral cavity. Rotate the rotating ring 9. Through the relative rotation of the rotating ring 9 and the connecting plate 10, and the threaded connection between the rotating ring 9 and the handle 8, drive the guide post 3 and the upper support plate 4 to move upward, so that the upper support plate 4 and the lower support plate 2 are separated relatively, and the animal's oral cavity is dilated. After the dilation is completed, under the torsion force of the torsion spring 7, drive the rotating plate 6 to rotate, so that the rotating plate 6 protrudes from the inside of the rotating groove 5. At this time, the rotating plate 6 fits against the inner wall of the rotating groove 5 and cannot rotate continuously. The end of the rotating plate 6 is inserted into the gap between the animal's teeth. When the dilator disengages due to the animal's struggle during the oral cavity examination, the teeth in the oral cavity will exert a force on the rotating plate 6, pushing the rotating plate 6 to rotate further. At this time, the rotating groove 5 blocks the rotating plate 6 from continuing to rotate, thereby blocking the dilator from disengaging from the animal's oral cavity, making the installation of the dilator more secure. At the same time, rotate the screw 14 through the knob 15. Through the threaded connection between the screw 14 and the sleeve 13, the sleeve 13 drives the rectangular plate 11 and the handle 8 to move upward. Use the V-shaped limiting plate 12 to limit the left and right of the animal's lower jaw, and use the cooperation between the limiting plate 12 and the lower support plate 2 to clamp the animal's lower jaw up and down, making the installation of the dilator more secure.
