[0002] Medical research generally refers to a series of activities, including medical research, medical experiments, and medical analysis, that involve identifying problems in the medical field, analyzing research subjects (mostly live laboratory mice) to find possible solutions, and using medical research experiments and analyses to explore the inherent nature and laws of related medical problems. These activities provide theoretical basis for clinical problems in the medical field. When medical researchers study medical problems, they often use rats to test clinical drugs and clinical treatment methods.

[0003] Rats are one of the most commonly used laboratory animals in the field of medical research. Firmly and accurately fixing unanesthetized rats is a prerequisite for a series of experimental procedures, including: gavage, intraperitoneal injection, tail vein injection, and tail vein blood collection.

[0004] There are two main methods for fixing rats: trunk fixation and limb fixation. Currently, limb fixation involves laying the rat flat and fixing its limbs with plaster or wire.

The head can be adjusted separately when a head test is required without affecting the overall fixation effect. The limb fixing mechanism 4 and the tail fixing structure 5 are linked together. The gaps in the limb fitting grooves 11 allow the rat's limbs to be easily engaged in the arc-shaped locking plate 45. The concave plate 53 and convex plate 54 design facilitate the quick engagement of the rat's tail. By pulling the U-shaped plate 55, the rat's limbs are unfolded under the action of the arc-shaped locking plate 45, which facilitates the exposure of the rat's abdomen and prevents the limbs from being straightened and not securely fixed. By rotating the threaded rod 58, the threaded rod 58 is pressed into contact with the resistance plate 59, ensuring the relative position of the U-shaped plate 55.
