[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 In this embodiment of the present invention, a livestock oral cavity opener for animal husbandry and veterinary use includes an opening frame 1, a fixing strip 2 installed at the bottom of the opening frame 1, movable cavities 3 respectively opened inside the fixing strip 2 near both ends, a support member installed on one side of the opening frame 1, and a locking member installed at the bottom of the fixing strip 2. The support member can open the oral cavity of the livestock to different degrees, and the locking member can prevent the support member from being bitten by the animal and pressed down.

[0025] When in use, the support frame 1 has a U-shaped cross section, and the support frame 1 and the bottom fixing strip 2 form a square shape. The support can provide different degrees of external support to the animal's mouth, and the locking fastener can lock and fix the support to prevent the support from being closed by the bite of a large animal. It can also prevent the animal's mouth from closing and causing damage to the arms, fingers or medical equipment of medical personnel.

[0026] In one embodiment, the support includes a rotating rod 4 passing through the inner side of the fixing strip 2. Fixing grooves 5 are respectively opened on both sides of the support frame 1. A screw 6 passes through the inner side of the fixing groove 5. Two first bevel gears 7 are fitted on the outer side of the rotating rod 4. A second bevel gear 8 is fitted on the bottom of the screw 6. A driving block 9 is fitted on the outer side of the screw 6. A base plate 10 is connected to the other side of the fixing strip 2. An upper plate 11 is connected between the two driving blocks 9. Gaskets 20 are respectively laid on the outer side of the base plate 10 and the outer side of the upper plate 11. Limiting parts 21 are respectively provided at both ends of the screw 6. An extension plate 22 is respectively connected to one side of the base plate 10 and the upper plate 11. The limiting part 21 is rotatably connected to the support frame 1. The screw 6 passes through the driving block 9 and is screwed to it. The first bevel gear 7 meshes with the second bevel gear 8.

[0027] The upper plate 11 and the bottom plate 10 have curved cross sections, which better fit the animal's mouth. The pads 20 on the outside of the upper plate 11 and the bottom plate 10 are mainly made of rubber, which can protect the animal's mouth and teeth and prevent damage to the animal's mouth. The extension plate 22 on one side of the bottom plate 10 and the upper plate 11 can improve the adaptability of the bottom plate 10 and the upper plate 11 to adapt to the mouths of different livestock animals. The rotating rod 4 can drive the two first bevel gears 7 to rotate simultaneously. The first bevel gears 7 can drive the screw 6 to rotate through the second bevel gear 8. The two limiting parts 21 can limit and support the screw 6 to prevent the screw 6 from deviating. The screw 6 can drive the driving block 9 to slide in the fixed groove 5. The driving block 9 can drive the upper plate 11 to move closer to or away from the bottom plate 10 so that the upper plate 11 and the bottom plate 10 can provide different degrees of support for the animal's mouth.

[0028] Furthermore, the locking component includes a fixing part 12 fitted on the outside of the rotating rod 4 and located at the center. The bottom of the fixing bar 2 has two movable grooves 13. The outer side of the fixing part 12 has two sets of locking grooves 14 arranged in a circle. The inner side of the movable groove 13 is connected to a pad 15. The bottom of the pad 15 is connected to a pull rod 16. The bottom of the two pull rods 16 is connected to a connecting plate 17. One side of the connecting plate 17 is connected to two locking pins 18. The outer side of the pull rod 16 is fitted with a spring 19. The pad 15 is slidably connected to the movable groove 13.

[0029] In one embodiment, the fixing part 12 is cylindrical and can limit the rotation rod 4. The spring 19 can support the pad 15 upward, so that the pad 15 drives the connecting plate 17 close to the bottom of the fixing strip 2 through the pull rod 16, so that the locking post 18 at the bottom of the connecting plate 17 is inserted into the locking groove 14 on the outside of the fixing part 12, which can lock and fix the rotation rod 4, preventing the animal from biting and squeezing the upper plate 11 downward, causing the rotation rod 4 to reverse.

[0030] The working principle of this utility model:

[0031] First, insert the extension plate 22 on one side of the base plate 10 and the upper plate 11 into the animal's mouth. Then, pull the connection, causing the connecting plate 17 to drive the pads 15 at one end of the two pull rods 16 to compress the spring 19. Then, the connecting plate 17 drives the locking pin 18 to disengage from the locking groove 14. Then, the rotating rod 4 drives the fixing part 12 to rotate within the fixing strip 2. At the same time, the rotating rod 4 drives the two first bevel gears 7 to rotate simultaneously. At this time, the first bevel gears 7 drive the screw 6 to rotate through the second bevel gear 8. Then, the screw 6 drives the driving block 9 to slide within the fixing groove 5. At the same time, the driving block 9 drives the upper plate 11 away from the base plate 10, thereby causing the upper plate 11 and the base plate 10 to open the animal's mouth to different degrees. Then, medical personnel use the opening frame 1 and the animal's mouth to perform treatment on the animal.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
