Damping air flow damping mechanical structure stable in operation

The utility model relates to the technical field of damping air flow shock absorption, in particular to a damping air flow shock absorption mechanical structure stable in operation, which comprises a protective shell and a hemispherical shell, the universal bead is located on the inner side of the hemispherical shell and abuts against the inner wall of the hemispherical shell; the universal bead is limited and rotated on the inner wall of the hemispherical shell; the hemispherical shell and the universal bead are additionally arranged at the top end of the protective shell and located on the upper side of the fixing column, when the protective shell is connected with an outer object, the protective shell can be connected with the outer object through the universal bead, and in the using process, the protective shell is not prone to falling off. And even if the damping air flow shock absorption mechanism is contracted, any shearing force cannot be generated between the protective shell and the outside object,
