Technical field

The utility model relates to the technical field of animal ear tagging devices, in particular to an ear tagging device for mice.

Background technique

In mouse experiments, ear tagging is a commonly used method to distinguish mice. Faced with mice of different genotypes, many of them have no difference in appearance. By placing ear tags with numbers on any one of the mice, In the middle of the ear, it can be clearly distinguished by the number on the ear tag.

The existing ear tag consists of a triangular iron piece. One corner of the iron piece is not closed. Use ear tag pliers to align the unclosed opening of the triangular ear tag with the middle of the mouse's ear and clamp it firmly. The ear tag will pass through. The mouse ear forms a closed loop with another section to hang the ear tag on the mouse ear. The ear tag produced by this method appears as a rectangular closed loop hanging on the mouse ear. However, this method of ear tagging often causes the ear tag pliers to hit one mouse and change the ear tag. The ear tag needs to be placed on the ear tag pliers in advance before the mouse can be captured, which is inconvenient to operate.
