The powder feeding nozzle comprises a conical main body, a connecting section is arranged in the middle of the end face of the large-diameter end of the conical main body in an upward extending mode, external threads are arranged on the outer wall of the connecting section, and the connecting section is connected with internal threads of a handheld laser cladding gun barrel through the external threads. A light emitting cavity is formed in the middle of the conical body and the middle of the connecting section in a full-length mode, three powder feeding hole channels are evenly formed in the conical body at intervals in the same circumferential direction, each powder feeding hole channel is formed by connecting a threaded hole channel and an unthreaded hole channel in the powder outflow direction, the diameter of the threaded hole channel is larger than that of the unthreaded hole channel, and the diameter of the unthreaded hole channel is larger than that of the unthreaded hole channel. And the central axes
