Scaffold safe operating assembly

The invention relates to a scaffold safe operating assembly. The scaffold safe operating assembly includes steel pipes, a safety belt and a hook, wherein the steel pipes are installed on cross bars ofa scaffold through fasteners and located under the cross bars, and the hook is located at the tail end of the safety belt. The steel pipes are located above an operating range and connected with thecross bars only at the ends, the hook is provided with a plurality of steel balls in a penetrating mode, and the steel balls can only rotate but cannot move on the hook. When the hook is arranged on the corresponding steel pipe in a sleeving mode, the steel balls are in contact with the top and two sides of the corresponding steel pipe, and the fasteners enable certain gaps to exist between the corresponding steel pipe and the cross bars, so that the hook can pass through the gaps when the hook slides along the corresponding steel pipe without interference with the cross bars. According to thescaffold safe operating as
