[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an adjustable-size veterinary mouth opener, comprising a U-shaped rod 1. Both ends of the U-shaped rod 1 are narrowed inward to form annular connecting grooves 14. Connecting sleeves 2 are fitted onto the connecting grooves 14. Metal plates are installed on the opposite surfaces of the connecting sleeves 2. Rubber posts 3 are installed on the outside of the metal plates. A blocking plate 4 is provided at one end of the opening of the U-shaped rod 1. A gear 7 is provided on the outside of the blocking plate 4. One end of the connecting sleeve 2 is narrowed inward to form annular grooves. Multiple protruding teeth 6 are installed in annular structure on the annular grooves, which mesh with the gear 7. A drive mechanism is installed on the outside of the gear 7 to drive the gear 7, the protruding teeth 6, the connecting sleeves 2, and the rubber posts 3 to rotate.

[0021] In this embodiment, the drive mechanism includes a motor 9, a worm gear 13, a worm 12, and multiple supports 8. Each support 8 is mounted on one open end of the U-shaped rod 1. The worm gear 13 is mounted on the outer surface of the gear 7. The worm 12 is located below the worm gear 13 and is meshed with the worm gear 13. Each support 8 has a first bearing embedded in it at the position opposite to the worm 12. Both ends of the worm 12 are mounted with shafts, and the other end of each shaft is mounted in the inner ring of the first bearing. The motor 9 is mounted on one side of the support 8, and the shaft of the motor 9 is fixedly connected to the shaft on one side.

[0022] In this embodiment, a fixing plate 15 is installed between the brackets 8. A second bearing is embedded in the fixing plate 15. A central shaft is installed in the inner ring of the second bearing. The other end of the central shaft is fixedly connected to the gear 7 and the worm gear 13. The fixing plate, the second bearing and the central shaft can position the gear and the worm gear so that the gear and the worm gear can only rotate along the central shaft.

[0023] In this embodiment, multiple connecting parts 5 are protruding on the outer ring surface of the baffle plate 4. Each connecting part 5 is provided with a through hole. The connecting parts 5 are all sleeved on the U-shaped rod 1 through the through holes. The baffle plate can be sleeved on the U-shaped rod through the connecting parts.

[0024] In this embodiment, a fixing frame 10 is installed on the outside of the U-shaped rod 1, and a handle 11 is installed on the fixing frame 10.

[0025] In this embodiment, the outer surface of the metal sleeve is flush with the outer surface of the U-shaped rod 1, which increases flatness and avoids unevenness that would affect insertion into the oral cavity.

[0026] In this embodiment, the protruding teeth 6 do not protrude beyond the outer ring of the metal sleeve, thus avoiding interference with the insertion of the U-shaped rod into the oral cavity. The baffle plate can prevent the oral cavity from interfering with the gear during insertion, and the components outside the baffle ring need to be located outside the oral cavity.

[0027] In use, hold the handle and insert the U-shaped rod into the mouth. As the U-shaped rod enters, the motor is activated. The motor drives the worm gear, which in turn drives the worm wheel and gears. The gears then drive the convex teeth and connecting sleeve, which in turn drives the metal plate and rubber column. The outward rotation of the rubber column opens the mouth and replaces the U-shaped rod. The flexibility and diameter of the rubber column reduce the probability of injury, and the rotation of the rubber column allows for adjustment of the degree of mouth opening, increasing adaptability. Furthermore, the worm wheel and worm gear position the rotated connecting sleeve, metal plate, and rubber column.
