PURPOSE: An injection nozzle is provided to prevent the leakage of injection fluid using a ball or a packer, to install easily, to be recyclable several times, and to be capable of injecting the injection fluid using a hydro piston pump using an elastic packing. CONSTITUTION: An injection nozzle(1) comprises; a nipple(10) having a circular plate(4) unified to the end of a ball inserting part(3) of a circular pipe divided into an injection pipe(2) and the ball inserting part, wherein the inside and outside diameters of the ball spigot are larger than the injection pipe, and the circular plate has a contact hole(9) corresponded to the inside diameter of the ball inserting part and unified with the end of the ball spigot; a ball(5) inserted to the ball inserting part through the contact hole of the circular plate; a spring(6) inserted to the ball inserting part through the hole of the circular plate and supporting the ball to make the ball stop up the hole of the injection pipe; a stopper(7) stopping up the hole of the circular plate after the spring(6) is inserted into the hole of the circular plate.
