IK end bone to slide along spline

[Anonymous]

Hi all!

I looked around on forums or YT but I'm struggling in finding the right setup for my rigging.

I attach an image to show the problem.

Distance between 1-2 and 2-3 are fixed

Point 2 is children of Dummy 1

Point 2 and 3 are a ball joint do they can rotate freely.

I would like to rotate Dummy 1 and have point 3 to slide along axis AB in order to keep.

Do you have any suggestion?

Many thanks for the help.
