Corner protection sleeve for laying special cable

The utility model discloses a corner protection sleeve for laying a special cable, which relates to the technical field of cables, and is characterized in that a rotating block rotates to drive a bevel gear II to rotate so as to drive a bevel gear I to rotate, so that a driving rod is driven to rotate; external threads of the driving rods are matched with internal threads in the sleeving columns to drive the two sets of sleeving columns to move at the same time so as to drive the rack to move, the rack and the gear can drive the gear to rotate so as to drive the rotating shaft to rotate, and therefore the connecting base is driven to rotate, and bending of the special cable at different angles can be achieved; the special cable can be kept at the angle, damage to an internal cable core caused by repeated bending is prevented, the bending position of the special cable is sleeved with the sleeve and the telescopic hose, the bending position is protected, and the risk that the bending position of the special cab
