Spacing-adjustable electric power fitting

The invention discloses a spacing-adjustable electric power fitting, which comprises a limiting ring, a plurality of adjustable limiting rods are arranged on the limiting ring, a plurality of adjusting assemblies are arranged on the plurality of limiting rods in a penetrating manner, and two limiting assemblies are connected to each of the plurality of adjusting assemblies. According to the device, a worker can directly press the two limiting columns, so that the limiting rod can be separated from limiting, the worker can conveniently detach the limiting rod, meanwhile, due to the fact that the multiple limiting columns are arranged on the limiting rod, according to the operation mode, the device also facilitates the worker to adjust the positions of the limiting columns, and the working efficiency is improved. In this way, the device not only can adjust the position of the limiting rod, but also can facilitate a worker to detach the limiting rod, so that the device can adapt to different cables, the worker d
