The invention provides a blind rivet tensioning device of a blade with a hole. The blind rivet tensioning device comprises a numerical control indexing shaft, a clamping jaw pull rod, a quad blind rivet clamping jaw, a blind rivet seat, a blade blind rivet, a blade seat, a blade, a pull rod piston, a tensioning spring, a rotary oil cylinder, a piston stop block, an oil cylinder rear end cover, a closed plug screw and a device body. The device is used for clamping a mechanically-clamped blade with a positioning hole on the numerical control indexing shaft, complete machining of the periphery of the blade can be achieved, positioning is achieved through the blade positioning hole, the blade blind rivet and the blind rivet seat, compared with positioning through the outer contour of the blade, the position precision of all the edges of the blade relative to a reference incircle is easier to guarantee, complete machining of the periphery of the blade can be completed through one-time clamping, the blade positioni
