The invention relates to the technical field of blades, in particular to a conveniently-adjusted-type fan blade. The conveniently-adjusted-type fan blade comprises a motor box, a rotating shaft, a first sleeve, a second sleeve, a main body blade, an expanding blade and an end block. According to the conveniently-adjusted-type fan blade, the expanding blade is arranged, sleeve sleeving design is adopted, the wind guiding efficiency can be enhanced when the fan blade is connected with the sleeves of the main body blade to be integrated; meanwhile, rotary inserting connecting matching is achieved, the relative deflection angles of the expanding blade and the main body blade are conveniently changed, and the turbulence effect is adjusted; and when the fan blade is connected with the rear side motor box to be integrated, the fan blade is separated from the rotating shaft and conveniently folded, and blocking for the main body blade is avoided.
