[0002] In a physiological laboratory, small animals such as rabbits are often used for various experiments. Generally, such experiments require fixing the rabbits and then performing blood collection or skin tests, etc. When fixing the rabbits, it is necessary to fix the rabbit legs to avoid the influence of the swinging of the rabbit legs on the experiment.

[0003] The utility model with the publication number of CN214342767U discloses a fixing frame for rabbit legs, including an extension plate and a bottom fixing seat. A fastening bolt is threadedly connected to the upper surface of the extension plate. One side of the extension plate is fixedly connected to the bottom fixing seat. An inner card slot is opened at the top of the bottom fixing seat, and a waste liquid box is slidably connected inside the inner card slot.

[0004] In the above technical solution, through the settings of the adjusting bolt and the leg ring frame, the leg ring frame and the arc guide plate are adjusted adaptively, and the adjusting bolt clamps and fixes both sides of them, so as to limit the contact activities of the legs of the experimental rabbit, ensuring the safe operation of the experimental personnel on the experimental rabbit during the experiment. Through the setting of the waste liquid box, the waste liquid box corresponds to the lower body position of the experimental rabbit, so that when the experimental rabbit is frightened and urinates frequently, it can provide a centralized collection effect for the urine, reducing the problem that the urine of the experimental rabbit contaminates the outer desktop too much, and indirectly ensuring the hygiene of the experimental environment. However, the leg fixing frame is not convenient for tightly bundling and fixing rabbit legs of different sizes, and it is not convenient to adjust the opening angle of the rabbit legs after fixing.
