Ground wire apparatus

The utility model relates to a ground wire apparatus, including electrically conductive end terminal, radiation formula angular adjustment mechanism, insulating bar, insulating bar includes the many unequal insulator spindles of diameter, the every inside cavity of insulator spindle, and the inside at the insulator spindle that the diameter is big is inserted to the one end of the insulator spindle that the diameter is little, be equipped with the locking structure between arbitrary two adjacent insulator spindles, the locking structure is used for locking and unclamping both when the relativerotation is made to two insulator spindles, the lower extreme of electrically conductive end terminal is connected with radiation formula angular adjustment mechanism, and the minimum insulator spindle of diameter is connected with radiation formula angular adjustment mechanism among the insulating bar, and radiation formula angular adjustment mechanism is used for the contained angle between electrically conductive end
