External source injection fixer in incubation period of fowls cytula

The utility model relates to an exogenous substance injection and holding device for fertile eggs of avian, comprising an injection needle, a holding part and a soft connecting pipe connected with the injector, characterized in that the front end of the injection needle is provided with a bent part which has an acute included angle with the center axis of the needle, the inner space of the holding part is a guidance cavity for the exogenous substance, the front end is communicated with the inner cavity of the injection needle arranged in the holding part, and the back end is fixed with one end of the soft connecting pipe, which becomes gradually large and turns into a blind end at the other end, which is used as an injection part engaged with injectors. The utility model is characterized in that an injection is done directly without opening multiple injection holes on the fertile egg, which effectively prevents damage and multi-time pollutions towards the fertile egg produced by opening injection holes on the egg for multiple times. Meanwhile, the injection needle is not injected into the content of the fertile egg or the body of the growing avian, which prevents damage made by the injection operation and improves the hatchability and livability of the fertile eggs, so that the operational sequence is greatly simplified, and the efficiency of processing is improved.
