[0002] Experimental mice are currently the most widely used experimental animals and play a very important role in exploring the basic functions of genes, the pathogenesis of diseases, and the pre-clinical screening of drugs. The reason is that the genes of mice and humans have a very high similarity. Compared with experimental animals such as monkeys and pigs, due to the small size of mice, they are convenient to raise and manage, easy to control, grow and reproduce quickly. Therefore, a large number of closed colonies and inbred lines have been obtained, making them the experimental animals with the largest usage, the widest application, the most varieties, and the most clearly studied at present. However, before conducting experiments such as brain trauma experiments or brain virus injections on mice, it is necessary to first fix the heads of the mice.

[0003] For example, Chinese Patent CN213941053U discloses a mouse head fixing device, which includes a base. Two ear fixing mechanisms for fixing the ears of the mouse and a mouth fixing mechanism for fixing the bridge of the nose of the mouse are successively arranged on the base. The mouth fixing mechanism includes a U-shaped bracket, a vertical adjustment component, a horizontal adjustment component, and a nose pressing component. The vertical adjustment component is arranged on the U-shaped bracket, the horizontal adjustment component is arranged on the vertical adjustment component, and the distal end of the horizontal adjustment component is provided with the nose pressing component, and the nose pressing component is used for clamping and fixing the bridge of the mouse's nose to fix the mouse's mouth.
