As you can see from the image below the twisting mechanism which holds the longer stick to adjust the angle of the blind as broken.
Any ideas on how this can be fixed, either by fitting a new twisting mechanism in or a DIY hack?

I would repair this by fitting a short piece of aluminum, copper or brass tubing over the nubbin of the shaft. This can be glued in place using epoxy. Before installation the end of the tubing can be worked to make a new end to engage the wand. The simplest (working with copper is especially nice) way would be to squeeze the end of the tubing flat. Then trim the corners of the flattened section to a rounded end profile. Finally make a hole in the end that can take a ring linkage from the adjustment wand.
I was going to draw a picture of the idea but it was faster to just make a sample of the proposal. Just choose the tubing with an inner diameter that is close to the size of the nubbin. The hole for the linkage gets drilled through the flattened end. Before trying to apply the epoxy in the tube do use a Q-Tip dipped in isopropyl alcohol to clean away any possible oil film left from the manufacturing of the tubing.
If these are slatted miniblinds, each of the vertical strings goes down through the bottom rail and is held in place by a little button. Once you pop out those buttons with a small screwdriver, the strings are free and you can remove the bottom rail. Then you can un-thread the extra slats and re-thread the bottom rail back on, cut the strings and replace the buttons.
This happened to one of our cordless blinds (made by Bali), they were stuck and would not raise or lower. I'm not certain that all types are made the same, but in the Bali blinds at least you can remove the top cover and there are one or more spring tensioned cylinders (for lack of a better term), and the blind cord may be wrapped around one of them incorrectly.
It's not fun, but I had to unspool and respool all of the blind cords until all were wound correctly around their cylinders, which required a surprising amount of force. I'm sure this makes little sense as typed, so here's a youtube video that helped. Your blinds may be a little different if they're from a different manufacturer.
