How do I tension my Qiyi Qidi 2x2?

[stormtrooper]

I want to loosen my Qidi without breaking the plastic, I am trying but it is hard for me to understand. How can loosening/tensioning it be done without breaking plastic?

Yes. Just use your screwdriver to loosen the screw on each side. Only do a little at a time.
