The utility model relates to a fixed support for an intermediate joint of a hand-operated cable. Two sides of the middle part of a pedestal are symmetrically hinged with one ends of lower support rods, and the other ends of the lower support rods are hinged to one ends of upper support rods; the other ends of the upper support rods are hinged to a lower part of a wiring board. Positioning plates are fixedly installed in the middle of hinged axes between the lower support rods and the upper support rods. Concentric threaded holes are arranged in the centers of the positioning plates and a screw rod transversely passes through the threaded holes. One end of the screw rod projects out of the positioning plate and a rotary handle is fixedly installed on the end of the screw rod. The rotary handle possesses a bending part which is easy for holding by hands. The height of the fixed support for the intermediate joint of the hand-operated cable can be adjusted by successively rotating the rotary handle. The fixed support for the intermediate joint of the hand-operated cable is equipped with a rotary handle which can be adjusted by rotation, so that the height of the fixed support can be adjusted by manually rotating the rotary handle. Furthermore, the fixed support for the intermediate joint of the hand-operated cable also can be used for fixing cables, which brings convenience to construction sites, saves time and labor, and increases processing efficiency.
