Description

Technical Field

[0001] The utility model belongs to the technical field of animal husbandry, in particular to an oral cavity opener for animal husbandry. Background Art

[0002] Livestock and poultry include traditional livestock and poultry, mainly referring to wild animals that have been artificially domesticated and raised, can reproduce offspring normally, and have certain economic value to humans. Livestock: Pigs, sheep, etc. are generally called small livestock, and horses, donkeys, cattle, buffaloes and camels are called large livestock. The mouth opener, also known as the mouth opener, is an instrument used to hold open the mouth when breathing is difficult or the person is unconscious and needs gastric lavage.

[0003] Patent publication number CN 220655734 U discloses an animal oral retractor for animal husbandry and veterinary medicine. Its technical solution includes a housing, a knob 1 disposed on the front side of the housing, and a connecting shaft disposed on one side of the knob 1. The utility model facilitates adjustment of the adjustment frame toward or away from each other by providing the knob 1, a connecting shaft, a gear, an upper rack, a lower rack, an upper connecting block, a lower connecting block, a short connecting rod, and a long connecting rod, thereby enabling the device to retract the left and right sides of the animal's oral cavity to an appropriate size. The adjustment frame, knob 2, a bidirectional screw, and an upper support rod facilitate retracting the upper and lower sides of the animal's oral cavity to an appropriate size. The upper and lower support rods are located on either side of the animal's oral cavity, thereby not hindering the veterinarian's frontal examination of the animal's oral cavity. Furthermore, the support rods and lighting provide increased illumination, making observation more convenient.

[0004] However, during the implementation of related technologies, it was discovered that the above-mentioned solution has the following problems: the existing technology has poor automation effect during use, requiring veterinarians to frequently manually adjust the positions of the adjustment frame, upper support rod, and lower support rod, which is both time-consuming and labor-intensive, and affects the efficiency and effectiveness of animal treatment. Therefore, a livestock oral retractor is proposed to solve the above-mentioned problems. Utility Model Content
