The utility model discloses an efficient electric pole number spraying device. The efficient electric pole number spraying device comprises a mounting plate and a plurality of hollowed-out letter press plates, the edges of the hollowed-out letter press plates extend outwards to form supporting lugs, the mounting plate is provided with window holes and strip-shaped holes, the strip-shaped hole are matched with the supporting lugs and used for fixing the hollowed-out letter press plates, and the mounting plate and the hollowed-out letter press plates are flexible plastic plates. By adopting the plastic hollowed-out letter press plates capable of being used repeatedly, the defect that paper hollowed-out plates need to be replaced frequently is overcome, the preparation time of the electric pole number spraying device is greatly shortened, and the labor intensity of workers is greatly relieved; due to the fixing structure that the hollowed-out letter press plates are inserted into the strip-shaped holes through the supporting lugs, no gaps are formed between the hollowed-out letter press plates and an electric pole, and efficient spraying and clear sprayed words are guaranteed. Besides, the whole device is simple in structure, convenient to operate, low in cost and suitable for popularization.
