Description

Technical Field

[0001] The utility model relates to the technical field of medical experimental equipment, in particular to an animal fixing device for animal experiments. Background Art

[0002] Veterinary medicine mainly studies the basic knowledge and skills of the occurrence and development of animal diseases, the diagnosis and prevention of animal diseases, and the prevention and treatment of diseases in livestock, companion animals, medical experimental animals and other ornamental animals. At present, in order to better conduct research on veterinary medicine and promote the development of medicine, it is usually necessary to conduct experimental research on animals in the laboratory, such as dissection, injection and drug feeding; and due to the uncertainty of the animals themselves, it is usually necessary to clamp and fix the animals before the experiment to ensure that they will not move or run around during the operation or injection, thereby avoiding inaccuracy in the experiment.

[0003] When clamping and fixing experimental animals, a clamping device is usually required. In order to meet the needs of clamping animals of different sizes, the existing clamping and fixing devices are equipped with an inclined telescopic rod to appropriately adjust the telescopic length of the telescopic rod according to the size of the animal to be clamped, so as to move the clamping assembly to the limbs of the animal to be tested for stable clamping, so as to better conduct the experiment. Although this method can effectively stably clamp the limbs of animals of different sizes, it will also introduce some new problems.

[0004] Because the telescopic rod needs to be adjusted according to the size of the animal to be clamped, and the size of the animal includes the length of the animal's body on the one hand, and the width of the animal, that is, the fatness of the body on the other hand, the connection between the telescopic rod and the base plate must be set as a rotating connection, that is, the telescopic rod can adjust its own angle. At this time, some limiters are inevitably needed to control the appropriate rotation of the telescopic rod. Most of the existing ones directly limit the rotation of the telescopic rod by tightening the limiter to make the limiter close to the base plate. This placement is not only troublesome to adjust, but also if the limiter is not close to the base plate, the telescopic rod will rotate back and forth, which will affect the stable clamping of the experimental animal's limbs, thereby affecting the progress of the experiment. Therefore, it is very necessary to set up a reasonable animal fixing device for animal experiments. Utility Model Content
