[0015] 2. The non-woven fabric fixing band or the elastic bandage is used to be wound and bound on the head of the small animals, is more close to the head of the small animals, the small animals feel more gentle and comfortable, and the resistance of the small animals during the test is reduced.

[0016] 3. The magic tape is installed at the end of the fixing band, as the animal grows, the size gradually increases, the tightness degree of the fixing band can be adjusted by adjusting the position of the magic tape, the fixing band does not need to be replaced and disassembled, the test process is not interrupted, and the efficiency is convenient.
