The embodiment of the utility model discloses an anti-oscillation damping spacer rod, which comprises a body frame and a wire clamp connected onto the body frame. The wire clamp at least includes a rotary wire clamp; the rotary wire clamp consists of an outer wire clamp and an inner wire clamp; the outer wire clamp is connected with the body frame; the inner wire clamp is wrapped inside the outer wire clamp and provided with chloroprene rubber on the inner side; and the inner wire clamp is axially fixed inside the outer wire clamp and freely rotates by adopting an center axis of the outer wire clamp as an axle. The anti-oscillation damping spacer rod has the advantages that by adopting the structure that the inner wire clamp is axially fixed inside the outer wire clamp and rotates freely in circumferential manner, a lead wire is enabled to rotate more freely and flexibly and more effectively prevent oscillation; and rotating portion is also enabled not to easily affected by environment to have failure, thereby ensuring work reliability of the damping spacer rod, accordant connection method of the wire clamp and the frame with a method frequently used in China, and needing no special tools for installation.
