A single waterway shaft structure includes a valve housing, a valve cover, a temperature control rod assembly composed of a water stopper and a temperature adjustment rod, a spring, and a gasket. A lower portion of the temperature control rod assembly is formed with an eccentric water hole. The gasket and the spring are placed in an eccentric water inlet of the valve housing in order and confined in the valve housing. The temperature control rod assembly cooperates with a faucet handle. A one-way connecting structure is provided between the valve cover and the valve housing. An upper end of the valve cover is provided with a fan-shaped limit block for limiting the turning angle of the temperature control rod assembly. The shaft is designed to be one-piece.
