The invention discloses a rapid joint of a precast concrete pile. The rapid joint comprises a stretching positioning sleeve I and a stretching positioning sleeve II which are both of a sleeve shaped structure; limiting ends for limiting end heads of steel bars inside are arranged at the bottom parts of the stretching positioning sleeve I and the stretching positioning sleeve II. The rapid joint further comprises a guide clamp and a reverse spring buckling pin; the guide clamp is in threaded fitting with the stretching positioning sleeve I; the reverse spring buckling pin comprises a screwing base, and at least three reverse buckling teeth fixed on the screwing base, wherein the reverse buckling teeth are extruded to pass through the guide clamp and then sprung back to be limited on the guide clamp; the screwing base is in threaded fitting with the stretching positioning sleeve II. The rapid joint is high in strength, simple to assemble and abut, free of damage on a connecting part body, flexible to abut, high in sealing after abutting, and high in stretching resistance and corrosion resistance.
