The upper three in blue arrow have the nuts to fasten the screw, while the lower three in red arrow have no nuts.
My question is, how to fasten the lower metal arms with screws if no nut inside, only by strong screw-in or other way?

But you have 6 bolts no? Honestly looks like the square nut has fallen or is misaligned. I'm not sure how they are retained my machine is currently in storage so I can't quickly check - you might have better luck on LFF or by emailing Michael @ ScanSolutions.
I also thought at first that a nut had fallen off, but when I shook the top cover, there was no nut shaking sound, and it was unlikely that all three would fall off at the same time.
I have sent an email to Michael, and I am waiting for a reply
