The utility model relates to a self -adaptation angle regulation's damper belongs to overhead transmission line gold utensil technical field. Technical scheme is: solar charging formula protective case (2) is disposed under the line clamp (1), detection module (3), information sensing module (4), self -adaptation adjusting module (6) are connected with solar charging formula protective case (2) respectively, detection module (3) interconnect through information sensing module (4) and self -adaptation adjusting module (6), hammer block (7), steel strand wires (8) interconnect with self -adaptation adjusting module (6), mode switch key (5) interconnect with self -adaptation adjusting module (6). The beneficial effects of the utility model are that: through adopt self -adaptation adjusting module can the automatically regulated hammer block with the angle of steel strand wires.
