The device includes: a housing, an inoculation loop container, a spring-loaded assembly, and a central rod; a spring-loaded hole is formed on the top surface of the housing; the inoculation loop container is disposed inside the housing with its bottom surface inclined; the spring-loaded assembly includes a spring-loaded button, a metal rod, an inoculation loop clamp, and a spring; the spring-loaded button is located on the top surface of the housing; the metal rod is connected to the spring-loaded button and the inoculation loop clamp; the inoculation loop clamp passes through the inoculation loop container and has a gripping structure at one end, and is movably connected to the central rod at the other end; the spring is connected to the outside of the inoculation loop container and the inoculation loop clamp; the central rod is located at the bottom of the housing. When the spring-loaded button is pressed, the inoculation loop clamp moves downwards; when the spring-loaded button is released, the spring drives the inoculation loop clamp to reset, and simultaneously, the gripping structure of the inoculation loop clamps the disposable inoculation loop inside the inoculation loop container and ejects it through the spring-loaded hole. This disposable inoculation loop ejection device has a simple structure, is easy to operate, and avoids contamination.
