Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of animal husbandry and veterinary medicine, especially a kind of anti-break needle injector for animal husbandry and veterinary medicine. BACKGROUND

[0002] Animal husbandry is the physiological function of animals such as livestock and poultry that have been domesticated by people, or wild animals such as deer, mink and quail, through artificial feeding and breeding, so that they can convert plant energy such as forage and feed into animal energy to obtain livestock products such as meat, eggs, milk and silk. In the process of animal husbandry, animals will inevitably get sick, and need to inject medicine through an injector to improve the immunity of animals. In real life, when animal husbandry uses an injector for injection treatment of livestock and poultry, the injector needs to be injected into the body of livestock and poultry. Since most injectors are provided with a needle breaking prevention mechanism, the animal will move around during injection, which can easily cause the injector to break.
