[0002] In the process of raising livestock, in order to ensure the health of the livestock, the health status of the livestock is checked regularly. The inspection is generally carried out by taking samples from the livestock's mouth. In order to ensure the normal sampling, a mouth opener is generally used to open the livestock's mouth.

[0003] The Chinese patent application number CN202023096299.5 discloses a livestock oral cavity opener, comprising a base, a first mounting hole is provided on the front side of the base, an internal threaded barrel is fixedly installed in the first mounting hole, a threaded rod is connected to the internal thread of the internal threaded barrel, a smooth rod is fixedly connected to the right side of the threaded rod, two groups of limiting bosses are fixedly connected to the surface of the smooth rod, and a connecting sleeve is sleeved on the smooth rod and located between the two groups of limiting bosses. The utility model extends two groups of opening plates into the animal's mouth, so that the two groups of opening plates are respectively located at the upper and lower positions in the animal's mouth, and the knob is rotated to make the threaded rod rotate in the internal threaded barrel, driving the smooth rod to rotate and move to the right, so that the connecting sleeve moves to the right under the restriction of the guide rod, thereby driving the right side of the opening arm to open through the force of the connecting rod, thereby driving the two groups of opening plates to move away from each other, opening the animal's mouth, and facilitating veterinary inspection.

[0004] However, when the above device is actually used, the veterinarian needs to fix the device with one hand and insert it into the livestock's mouth, and use the other hand to turn the knob to drive the expansion plate to expand the livestock's mouth. At this time, it is not convenient to fix the livestock's head. If the livestock resists and shakes its head, the device will be detached from the livestock's mouth, which is not convenient for the veterinarian to use for inspection.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0027] See also Figure 1-4 As shown, in this embodiment, a mouth spreader for livestock inspection is provided, comprising a support plate 1, a square rod 2 is slidably fitted in the support plate 1, a threaded rod 5 is rotatably fitted in the square rod 2, a spreader arm 6 is rotatably fitted at the top and bottom of the square rod 2, and a spreader plate 7 is mounted at one end of the spreader arm 6;

[0028] A limiting groove 8 is provided in the square rod 2, and a moving block 9 threadably matched with the threaded rod 5 is slidably fitted in the limiting groove 8. The top and bottom of the moving block 9 are rotatably matched with connecting rods 10. The ends of the two connecting rods 10 away from the moving block 9 are respectively rotatably matched with the two support plates 7. A support rod 3 is installed at the bottom of the support plate 1, and a fixing component 4 is installed on one side of the support rod 3.

[0029] One aspect of the application of this embodiment is as follows: first, the device is fixed to a suitable position by means of the fixing assembly 4, and then the veterinarian can fix the livestock head with one hand and push the square rod 2 with the other hand to move, so that the square rod 2 drives the expansion arm 6 and the expansion plate 7 to enter the livestock's mouth. At the same time, the veterinarian can control the position of the expansion arm 6 and the expansion plate 7 entering the livestock's mouth. After the expansion plate 7 is in a suitable position, the veterinarian rotates the threaded rod 5, and the rotation of the threaded rod 5 drives the moving block 9 to move, and the movement of the moving block 9 drives the two connecting rods 10 to rotate, and the rotation of the connecting rod 10 drives the expansion arm 6 and the expansion plate 7 to rotate, so that the expansion plate 7 supports the livestock's mouth.

[0030] By means of the fixed component 4, the fixed component 4 can be installed and fixed on the device, so that the veterinarian can push the square rod 2 to move the expansion arm 6 and the expansion plate 7 into the livestock's oral cavity, thereby facilitating the veterinarian to fix the livestock's head for oral cavity inspection. By means of the square rod 2, the square rod 2 can be pushed to move the expansion arm 6 and the expansion plate 7, so that the veterinarian can control the position of the expansion arm 6 and the expansion plate 7 entering the livestock's oral cavity, thereby facilitating adaptation to the oral cavity support of different livestock and facilitating veterinary inspection and use. By means of the threaded rod 5, the threaded rod 5 can be rotated to drive the moving block 9 to move, so that the moving block 9 drives the two connecting rods 10 to rotate, and the connecting rod 10 rotates to drive the expansion arm 6 and the expansion plate 7 to rotate, thereby facilitating adjustment of the opening angle of the expansion plate 7 to support the livestock's oral cavity.

[0031] like Figure 4 As shown, the support rod 3 of this embodiment includes a first rod body 301 and a second rod body 302. The first rod body 301 is installed at the bottom of the support plate 1 and is slidably fitted in the second rod body 302. The second rod body 302 is matched with the fixing assembly 4. A fixing bolt 303 is threadedly fitted on one side of the second rod body 302, and the fixing bolt 303 is matched with the first rod body 301. By setting the first rod body 301 and the second rod body 302, the first rod body 301 and the second rod body 302 can be pulled to make the first rod body 301 extend and retract in the second rod body 302, so as to adjust the height of the support plate 1. By setting the fixing bolt 303, the fixing bolt 303 can fix the adjusted first rod body 301.

[0032] like Figure 4As shown, the fixing assembly 4 of this embodiment includes a U-shaped plate 401 installed on one side of the support rod 3, a screw rod 402 threadedly engaged in the U-shaped plate 401, and a gasket 403 installed at one end of the screw rod 402, and the gasket 403 is located in the U-shaped plate 401. By setting the screw rod 402, the screw rod 402 can be rotated to drive the gasket 403 to move, so that the gasket 403 and the U-shaped plate 401 are clamped and fixed.

[0033] like Figure 1-2 As shown, the two opening plates 7 of this embodiment are both provided with a rubber pad 11 on the side away from each other, and the rubber pad 11 is an arc-shaped surface with a rubber protrusion. The rubber pad 11 can be fitted with the livestock mouth, reducing the damage caused when biting, and can better fix and support the livestock mouth.

[0034] like Figure 2 As shown, in this embodiment, a rotating wheel 12 is installed at one end of the threaded rod 5 that passes through the square rod 2. By means of the rotating wheel 12, the rotating wheel 12 can be rotated to drive the threaded rod 5. The threaded rod 5 rotates to drive the moving block 9 to move, so that the moving block 9 drives the connecting rod 10 to rotate, and the connecting rod 10 rotates to drive the spreading arm 6 and the spreading plate 7 to spread the livestock cavity.

[0035] like Figure 2-3 As shown, in the present embodiment, a plug rod 13 is slidably matched in the support plate 1, a plurality of slots 14 are provided on the top of the square rod 2, and the plug rod 13 is matched with the plurality of slots 14 respectively, a spring 15 is installed between the plug rod 13 and the top of the support plate 1, and a rounded corner 16 is provided at one end of the plug rod 13 that matches with the slot 14. Through the provided plug rod 13, the plug rod 13 can be inserted into the slot 14 to fix the square rod 2, so that the square rod 2 can be moved after the plug rod 13 is moved out of the slot 14, and through the provided rounded corner 16, when the square rod 2 and the opening plate 7 are pushed into the animal husbandry mouth, the square rod 2 moves forward to squeeze the rounded corner of the plug rod 13, so that the plug rod 13 squeezes the spring 15 to contract, so that it is convenient for the square rod 2 to drive the opening plate 7 into the animal husbandry mouth, and after the opening plate 7 enters the animal husbandry mouth, the spring 15 drives the plug rod 13 into the slot 14 through elastic force, so that the square rod 2 cannot be pulled backward.
