The utility model relates to a device for vertically stretching a ground wire and an optical cable on two sides of an overhead transmission line iron tower, which comprises a clamping seat fixed on angle steel at the top end of the iron tower, a lead screw connecting seat arranged at one end of the clamping seat, a one-way ratchet lead screw movably arranged on the lead screw connecting seat, and a first ratchet rocker arm arranged at one end of the one-way ratchet lead screw. A second ratchet rocker arm and a third ratchet rocker arm are arranged on the two-way ratchet screw rods on the two sides respectively, a U-shaped groove is formed in the other end of each two-way ratchet screw rod, each U-shaped groove is connected with a U-shaped ring, and each U-shaped ring locks a ground wire and an optical cable. By means of the device, the whole lifting process only needs 5 minutes, and the working efficiency is improved by 8 times in a breakthrough mode. And in addition, slipping and falling cannot occur, and pe
