The invention discloses a special platform for manufacturing cable intermediate joints, and relates to the field of cable accessory manufacturing tools. The special platform comprises a left connecting base, a right connecting base and a working frame, wherein the left connecting base is used for clamping left cable joints, and the right connecting base is used for clamping right cable joints; the left connecting base is connected to the left end of the working frame in a sliding manner; the right connecting base is fixedly connected to the right end of the working frame, and the axis of the left connecting base is the same as that of the right connecting base; a substrate is fixed in the axial direction of the working frame; the substrate is movably connected with a lead screw in a penetrating manner in the axial direction; the left connecting base is in connected with the lead screw in the sliding manner through a thread; a first gear is arranged at the left end of the lead screw, and a second gear engaged with the first gear is arranged on the working frame; and the second gear is connected with a handle. The special platform is beneficial for safe and stable operation of the cables, cable accident potentials caused by the fact that the joints and accessories are contaminated by soil in the manufacturing process of the cable intermediate joints are avoided, meanwhile the labor cost is reduced, and the labor efficiency is improved.
