A high-pressure inflation pump includes a head, a nozzle, a piercing member, and a resilient member. The head includes a compartment, a passageway, and a threaded section. The piercing member includes a base, a piercing portion, and an air guiding hole. The piercing portion includes an annular abutting shoulder for pressing against an end face of a threaded end of a high-pressure gas container engaged with the threaded section of the head, providing an airtight state. The resilient member includes a support end, a pressing end, and a chamber. The piercing member is received and positioned in the chamber without blocking flow of gas in the high-pressure gas container into the air guiding hole, allowing rapid inflation of a tire engaged with the nozzle and allowing the high-pressure gas container to be used many times to save resources.
