Power supply cable installation equipment convenient to adjust

The invention discloses a power supply cable installation device convenient to adjust, and particularly relates to the technical field of power supply construction, the power supply cable installation device comprises an annular cavity, the top of the annular cavity is detachably provided with an annular cover through a bolt, and a cable penetrates through the annular cavity; a driving mechanism is installed in the annular cavity in a hidden mode, three pressing mechanisms are arranged on the periphery of the annular cavity in a circular array mode, and the three pressing mechanisms are all in linkage with the driving mechanism. According to the cable conveying device, cables of different sizes can be adjusted and conveyed, the multiple limiting rollers on the three pressing mechanisms make contact with the cables and apply certain pressure to press the cables, the limiting rollers limit the rotation direction through the ratchet wheel and pawl assemblies, in other words, when the cables are pulled forwards,
