The invention discloses a self-adaptive centering tool rest for high-precision girdling of a high-voltage cable. The centering tool rest comprises two sets of outer fixing frames, positive and negative lead screws and an inner floating frame. The outer fixing frames are symmetrically and fixedly arranged on a rotating disc of the cable girdling platform, and the outer fixing frames are axially limited and circumferentially and rotationally connected with forward and reverse lead screws in an inserted mode. The two ends of the positive and negative lead screws are provided with external threads in opposite directions, the middle sections of the positive and negative lead screws are meshed and connected with inner floating frames in a sleeved mode, the distance between the inner floating frames is adjusted in the opposite directions, and the two positive and negative lead screws rotate in the same direction at the same speed. And the inner floating frame performs self-adaptive centering and radially pre-tighten
