The invention discloses a device for pasting an electric power communication cable label. The device comprises a bottom plate, a flag surface compressing assembly, a locking and adjusting assembly and a flagpole flattening assembly, wherein the bottom plate is used for arranging a flag surface; the flag surface compressing assembly is used for arranging and pasting the flag surface; the flagpole flattening assembly is used for flattening a flagpole; the bottom plate is provided with a flag surface arrangement groove for arranging the fixed flag surface, and the licking and adjusting assembly is fixedly connected with groove walls of a flagpole arrangement groove; the flagpole flattening assembly is hinged to the locking and adjusting assembly, the flag surface compressing assembly is hinged to the flag surface arrangement groove walls, and the center line of the flagpole flattening assembly and the center line of the flag surface compressing assembly are located on the same straight line. The flagpole flattening assembly flattens the flagpole, an operator oppositely folds the flagpole to wrap a cable, then the fixed flag surface arranged in the flag surface arrangement groove is well fixed, the phenomena of slippage and displacement are avoided, the flag surface compressing assembly completely pastes the pasted flag surface to the fixed flag surface, and complete attachment is achieved.
