A catenary post base device according to claim 8, characterized in that By adjusting the position of the positioning bolt (4) in the slot through hole (3) of the electric railway contact network double-wrist-arm base correction device, the telescopic frame (6) is driven to extend or retract, so as to correct the spatial installation posture of the upper base (17) and the lower base (18) of the contact network double-wrist-arm. The equal-diameter round column (20) or the transverse abdominal column (21), the adjusting frame (2), the two telescopic frames (6), the upper base (17) and the lower base (18) of the contact network double-wrist-arm jointly constitute two rotationally symmetrical triangular stable structures.
