The invention discloses an end hydraulic support spray head capable of outputting water stably. The end hydraulic support spray head comprises a shell and an end cap, wherein a water flow channel is arranged in the shell and communicates with the outside by a water spray outlet; the inner wall, close to one end of the water spray outlet, of the water flow channel is a horn-shaped inner surface of which the inner diameter is gradually increased towards the water spray outlet direction; the end cap is provided with a conical outer surface fitting with the horn-shaped inner surface; a diversion ring is fixed in the water flow channel and provided with water flow through holes; one end, close to the diversion ring, of the end cap is connected to the diversion ring by an elastic piece. According to the end hydraulic support spray head capable of outputting water stably disclosed by the invention, improvement on the spray head structure is achieved, and the sprayed water flow is stable in flow rate.
