the third step is that the upper swinging body is connected with the lower swinging body
Aligning a column hole at the lower end of an upper swinging body with a second curved-surface tetrafluoro slide plate on the top surface with a column head at the upper part of the spherical hinge body, and connecting the column head with the column hole through threads;

When the support bears the pressure to change and move, the included angle between the axes of the upper swinging body and the lower swinging body changes along with the change of displacement, and the pressure borne by the upper support plate always points downwards to the circle center of the sliding lining plate, so that the normal work of the support is ensured.
When an earthquake occurs, a pulling force is generated, the pulling force is transmitted to the inner wall of the spherical hinge cover plate by the upper part of the spherical body, and the spherical head can swing randomly in the through hole because the spherical body on the upper part of the spherical hinge body is in spherical contact with the inner wall of the spherical hinge cover plate and the upper part of the spherical body and the inner wall of the spherical hinge cover plate form a rotating spherical surface, and the top of the spherical hinge cover plate is provided with a through hole larger than the diameter of the head.
