The invention discloses a safe fuel truck nozzle capable of preventing dragging and realizing automatic fuel cut-off. The safe fuel truck nozzle comprises a fuel pipe, a fuel truck nozzle body, a handle, tensile force detecting units, cutting units and a valve unit; the tensile force detecting units are used for detecting whether the tensile force of the fuel truck nozzle body on the part, at thetail end of the handle, of the fuel pipe exceeds a set value or not; the cutting units are close to the part, at the tail end of the handle, of the fuel pipe; the cutting units is controlled to be started by the tensile force detecting units and are used for cutting off the part, at the tail end of the handle, of the fuel pipe when the tensile force value exceeds the set value and further separating the fuel pipe from the fuel truck nozzle body; and the valve unit is located on one side of the fuel pipe separated from the fuel truck nozzle body, is controlled to be closed by the tensile forcedetecting units and is used for closing the fuel pipe after the fuel pipe is separated from the fuel truck nozzle body. The safe fuel truck nozzle has the substantial effects that when an automobile drags a refueling pipe, the tensile force of the fuel truck nozzle body on the part, at the tail end of the handle, of the fuel pipe exceeds the set value, the cutting units automatically cut off the fuel pipe, and meanwhile, the valve unit in the fuel pipe is cut off to close the fuel pipe, and therefore gasoline leakage can be prevented.
