This utility model discloses an electrical fitting for cable fixing, belonging to the field of cable fixing technology. It includes an upper arc-shaped frame, with a lower arc-shaped frame located below it. A support rod is fixedly connected to the inner wall of the lower arc-shaped frame, and an adjustment box is fixedly connected to its front. An adjustment block and a limiting rod are slidably connected inside the adjustment box, and a hand-tightening limiting bolt is rotatably connected to the inner wall of the adjustment box. Two guide rods are slidably connected inside both the upper and lower arc-shaped frames. This electrical fitting for cable fixing, through the mutual cooperation of the upper arc-shaped frame, lower arc-shaped frame, support rod, guide rod, arc-shaped clamp, connecting plate, return spring, adjustment box, adjustment block, hand-tightening limiting bolt, limiting rod, fixing rod, and limiting lock block, allows the upper and lower arc-shaped frames to open and close relative to the support rod, wrapping the cable. Furthermore, under the return spring's rebound, the two arc-shaped clamps can tightly clamp cables of different sizes.
