A fishing cone for fishing sundries in a directional drill hole comprises a drill rod connector threaded rod connected with a drill rod, a mud hole connected with the drill rod connector threaded rodand a fishing threaded rod connected with the mud hole, and a plurality of discharge grooves are formed in the fishing threaded rod from the head to the tail of the fishing threaded rod. According tothe directional drilling device, stones, scrap iron, abraded parts, mud motors and the like in a directional drilling hole can be fished out of the hole, the problem of fishing sundries falling in thedirectional drilling hole is solved, and the drilling efficiency is greatly improved; moreover, the submarine pipeline anti-corrosion layer can be prevented from being damaged by sundries in the dragging process of the submarine pipeline, and the integrity of the anti-corrosion layer when the submarine pipeline lands is guaranteed.
