Geometry Question -- Modeling bolt with flange end

Homework Statement

Hi

I attached a picture of bolt call ed hollo bolt, in which the sleeves open when the cone pushed inside,, if i Know all the dimensions,

I ask an expert and he tell me that
However, the
difficulty is recognized for the modelling of the flaring sleeves due to the fact
that the contours of flaring sleeves are irregular in the coordinate system.
Identifying 3D coordinates of the nodes at the bottom of the flaring sleeve
becomes a key point in the configuration. In other words, this requires
knowledge of spatial curves & surface

could anyone help me or at least guide me.

Thanks
