In the process of treating cattle and sheep in livestock veterinarian, the oral cavity spreader main part 1 is used to open the animal mouth, first, the limiting band 22 is loosened to a certain length in the through-hole block 25, then the limiting band 22 is sleeved on the horn of the cattle and sheep head, then the end of the oral cavity spreader main part 1 is inserted into the animal mouth, when inserted, the end of the limiting band 22 inserted into the through-hole block 25 is held and pulled, in the process of pulling, the first limiting block 26 rotates to one end in the inner wall of the through-hole block 25, the torsion spring 27 is deformed, and the end of the first limiting block 26 jumps in the clamping grooves 23 under the restoring force of the torsion spring 27, when the inner wall of the limiting band 22 is tightly attached to the head of the cattle and sheep, the first limiting block 26 is clamped into the corresponding clamping groove 23, and the other side of the first limiting block 26 is blocked and supported by the stopper 28, the limiting band 22 is fixed and limited on the through-hole block 25, so that the oral cavity spreader main part 1 is limited on the head of the cattle and sheep after being inserted into the animal mouth, avoiding the oral cavity spreader main part 1 from falling off or being unstable during observation and treatment, which can free the hands of the veterinarian, facilitate the veterinarian to observe and treat the animal mouth, improve the efficiency of observation and treatment, and facilitate use.

[0029] Reference Figure 2 and Figure 3As shown, the first limiting block 26 is fixedly connected with a connecting block 29 on one side, and the connecting block 29 is fixedly connected with a pulling block 210 on one side. By setting the connecting block 29 and the pulling block 210, when it is necessary to loosen the limiting band 22 to release the limiting, the limiting band 22 can be pulled to a certain position at one end first, so that the first limiting block 26 is loosened in the clamping groove 23, and then the pulling block 210 is held and pulled to one end, so that the first limiting block 26 can be pulled out of the clamping groove 23 under the driving of the connecting block 29. At this time, the limiting band 22 can be loosened from the through hole block 25 to facilitate the removal of the limiting band 22 from the head of the cattle and sheep.

[0030] Referring to Figure 2 and Figure 3 As shown, the first rotating block 21 and the second rotating block 24 are fixedly connected with a bearing 211 on one side, and the inner ring of the bearing 211 is fixedly connected with the oral cavity dilator main body 1 on one side. By setting the bearing 211, the rotating wear between the first rotating block 21 and the second rotating block 24 and the oral cavity dilator main body 1 can be reduced, and the service life of the two can be improved. One end of the limiting band 22 is fixedly connected with a protruding block 212, and the longitudinal section of the protruding block 212 is trapezoidal. By setting the protruding block 212, the area of one end of the limiting band 22 can be reduced, so that one end of the limiting band 22 can be quickly aligned and inserted into the inner wall of the through hole block 25, and the installation is facilitated.

[0031] Referring to Figure 4 As shown, the auxiliary device 3 comprises a U-shaped block 31, one side of the U-shaped block 31 is fixedly connected with the oral cavity dilator main body 1, one side of the U-shaped block 31 is fixedly connected with a recessed elastic arc block 32, one end of the recessed elastic arc block 32 is rotatably connected with a threaded rod 33, the other end of the threaded rod 33 is inserted into the other end of the recessed elastic arc block 32, the outer surface of the threaded rod 33 is threadedly connected with a threaded hole block 34, and the outer surface size of the threaded hole block 34 is larger than the inner wall size of the recessed elastic sliding block. When the oral cavity dilator main body 1 is used to cooperate with the stomach washing tube to perform stomach washing treatment on the cattle and sheep, the stomach washing tube can be first inserted into the inner wall of the recessed elastic arc block 32, and then inserted into the inner wall of the oral cavity dilator main body 1, so that it enters the stomach of the livestock. After holding the threaded rod 33 and rotating it to a certain position in the one end of the recessed elastic arc block 32, the other end is inserted into the other end of the recessed elastic arc block 32, and then the threaded hole block 34 is screwed to a certain position, so that one side of the threaded hole block 34 abuts on one side of the recessed elastic arc block 32 to extrude it, so that it is contracted and the stomach tube is clamped and fixed on the oral cavity dilator main body 1. In this way, when performing stomach washing treatment, it is not necessary to hold the stomach tube and perform other operations at the same time, which liberates the hands of the veterinarian, facilitates the operation of other steps, improves the treatment effect, and makes the oral cavity dilator main body 1 convenient to use.

[0032] Referring to Figure 4As shown, the embodiment discloses that the outer surface of the screw hole block 34 is fixedly connected with a plurality of screw blocks 35, and the plurality of screw blocks 35 are arranged at equal distances.

The inner wall of the recess elastic arc block 32 is fixedly connected with a plurality of anti-skid blocks 37, and the anti-skid blocks 37 are made of rubber. By arranging the anti-skid blocks 37, the contact friction of the inner wall of the recess elastic arc block 32 can be increased, and when the stomach tube is clamped and limited, it is more firm and stable.

[0033] The working principle is that when the oral cavity expander main body 1 is used to open the animal mouth during the treatment of cattle and sheep livestock by the veterinarian, the limiting belt 22 can be loosened to a certain length in the through hole block 25, and then the limiting belt 22 is sleeved on the horn of the head of the cattle and sheep, at this time, the one end of the oral cavity expander main body 1 is inserted into the animal mouth, when inserted, the one end of the limiting belt 22 inserted into the through hole block 25 is held, and then pulled to one end, in the process of pulling, the first limiting block 26 is driven to rotate to one end in the inner wall of the through hole block 25, and the torsional spring 27 is deformed, and the one end of the first limiting block 26 is continuously driven to jump in the plurality of clamping grooves 23 under the restoring action of the torsional spring 27, when the inner wall of the limiting belt 22 is tightly attached to the head of the cattle and sheep, the first limiting block 26 is clamped into the corresponding clamping groove 23, and the other side of the first limiting block 26 is blocked and supported by the blocking block 28, so that the limiting belt 22 is fixed and limited on the through hole block 25, so that the oral cavity expander main body 1 can be limited on the head of the cattle and sheep after being inserted into the animal mouth, so that the situation that the oral cavity expander main body 1 is dropped or not gripped stably due to the movement of the livestock during observation and treatment is avoided, so that the hands of the veterinarian are freed, the veterinarian can observe and treat the inside of the animal mouth, the efficiency of observation and treatment is improved, and the use is convenient.

[0034] In use, the stomach-washing tube is first inserted into the inner wall of the recessed elastic arc block 32, and then inserted into the inner wall of the oral cavity expander main body 1, so that it enters the stomach of the livestock. After holding the threaded rod 33 and rotating it to a certain position in the inner wall of one end of the recessed elastic arc block 32, the other end is inserted into the inner wall of the other end of the recessed elastic arc block 32. Then hold the knob 35 and rotate the threaded hole block 34 on the threaded rod 33 to a certain position, so that one side abuts against one side of the recessed elastic arc block 32 to extrude it and make it shrink to clamp and fix the stomach tube on the oral cavity expander main body 1. In this way, during the stomach-washing treatment, the veterinarian's hands are freed up for other operations, improving the treatment effect and making the oral cavity expander main body 1 easy to use.
