Wheelchair Drink Holder

I bought a ultra light carbon folding wheelchair which is fab. But the cycle !!!! Cup holder won't fit on anywhere. Just found out my husband has terminal cancer , so returning it is the least of my problems .I was going to visit my husband using the cup holder . If you could send me a photo of were it should be placed

It moves a little too much despite being tightened. Also the screw has scratched me and torn my clothes a couple of times

Did what it said .. held my can easily and easy to fit
