The invention discloses a pre-assembling type jointed drawing and anchoring integrated device for submarine cables. The pre-assembling type jointed drawing and anchoring integrated device comprises a pipe opening, an anchoring base, connecting flanges, a flange, a cushioning plate and a plurality of connecting joints, wherein the connecting joints are connected in an end-to-end manner; the anchoring base is tightly clamped by the flange which is fixedly connected with the pipe opening simultaneously; the connecting joints are fixedly connected with the anchoring base by the connecting flanges; each connecting joint comprises a connecting shaft, a rear conical sleeve, a front conical sleeve and a bearing shaft; the bearing shafts are of spherical structures and are connected with the connecting flanges by threads; the connecting shafts are connected with the rear conical sleeves by threads; and the connecting shafts, the bearing shafts and the rear conical sleeves form a spherical structure with an untwisting function. The pre-assembling type jointed drawing and anchoring integrated device disclosed by the invention has the advantages that due to adoption of the drawing-head and anchoring integrated structure, the main-body part of the whole device is installed in a factory and the marine operation is not needed, so that the efficiency of marine construction is greatly improved.
