Description

Anti-hanging ear ear clamp Technical field

The invention relates to the technical field of ear tag clamps, and in particular to an anti-hanging ear tag clamp.

Background technique

At present, ear tagging for livestock and poultry requires operation with ear tag clamps. The conventional ear tag tongs of the market are provided with springs, and after the ear tag operation is completed, the caliper handles are separated by spring resetting, thereby separating the main standard and the sub standard. Because the painful animals are easily reacted when the ear tag is hit, the animal quickly escapes, and the design of the traditional ear tag clamp itself has limitations, that is, the speed of the separation of the two pliers is slow, and the animal is easy to escape when the pain is felt. Tearing to the ear of an animal not only makes it easy to smash the ear of the animal, but also causes a lot of bleeding, and the ear tag clamp is easily driven off and damaged by the animal. The design of the traditional ear tag pliers is more problematic for operators who are inflexible and slow to respond. In addition, there are now available automatic rebound ear clips on the market, such as the application number CN201420747721.4, the name of the "automatic rebound ear clips" invention patent, by setting the rebound self-locking on the movable handle The mechanism realizes the automatic rebound of the ear tag clamp. However, such ear tag clamps also have some problems, such as the reaction time required in the back mark; in addition, the structure of such ear tags is too complicated, and the small parts are difficult to use, and it is not easy to repair when the ear tag clamps fall down.

In summary, the existing ear tag pliers have the problem of slow backing speed, easy tearing of the animal's ear or damage to the ear tag pliers after the ear tag operation is completed. Therefore, it is necessary to design a simple and easy-to-operate anti-hanging ear tag clamp to solve the existing problems. In addition, according to the same principle, the double-hole ear tag which may appear in the future can be made into a double-needle ear tag or a single-needle or double-needle dual-use ear tag pliers, which can meet various needs of operation.
