The working process of the invention is as follows:

when the signal lamp post is used daily, when the signal lamp post 1 shakes and swings due to the influence of slight external force collision or severe windy weather, when the signal lamp post 1 shakes under the action of external force, the elastic supporting piece 32 in the tuning damping ball head 3 moves in the direction opposite to the swinging direction of the signal lamp post 1 through inertia all the time, traction force in the opposite shaking direction is provided for the signal lamp post 1 through the traction of the mass ball block 33, so that the shaking amplitude of the signal lamp post 1 is reduced, the amount of exercise of the signal lamp post 1 is tuned until the signal lamp post 1 stops shaking, and therefore structural strain caused by the overlarge movement amplitude of the signal lamp post 1 and falling damage of a connecting piece are prevented;
