引きおろす is a compound verb (引く 'pull' + 降ろす 'lower') — 'pull down.' Compounds with 引き~ emphasize the pulling motion: 引き出す ('pull out, withdraw'), 引き下げる ('pull down, lower'), 引き寄せる ('pull close'). Compared with the simpler 降ろす ('lower'), 引きおろす specifically describes a manual pulling action — a tactile, physical down-motion of the hand. The compound is more vivid: you can almost feel the cord coming down.
