A rolling ball telescopic fan blade comprises rolling balls, a rolling ball frame, a plurality of contact sliding blocks and at least two stages of limiting clamping buckles. The rolling ball telescopic fan blade is characterized in that the rolling ball walks along slideway of the telescopic fan blade to be in sliding contact with the fan blade; a rolling ball frame fixed shaft is connected withand supports the rolling balls to walk along the slideway of the telescopic fan blade; or a rolling ball frame shaftless frame sleeve supports the rolling balls to move along the slideway of the telescopic fan blade; the limiting clamping buckles are fixedly connected to the inner sides of one ends of slideways on the two sides of each section of telescopic fan blade and the outer sides of the other ends of the slideways on the two sides of each section of telescopic fan blade, and at least two limiting clamping buckles are arranged in a linear array mode to form at least one first-stage buckle second-stage disengagement prevention; the contact sliding blocks are arranged on the surface of the fan blade and the slideways; the cross section of one end of the sleeve is plugged to strengthenan anti-tripping buckle; friction and bending resistance of the fan blade are reduced through the rolling balls, piers, pits or T-shaped ribs, friction between the contact sliding blocks and the fan blade is reduced through graphite, and the strip-shaped contact sliding blocks protrude outwards or protrude inwards to make contact with the fan blade in a sliding mode and clean the fan blade. The fan blade is connected with an anti-falling fuse, and a power supply is turned off automatically by a multi-stage buckle anti-falling device, a safety rope anti-falling device and a tripping device, sothat the diameter of the fan blade is conveniently increased and decorative lighting is flexibly matched.
