Can't do adjustment in clutch cable in motorcycle

I installed a new clutch cable on my bike but after installation, its adjustment bolt was tighten at last. I don’t understand why it is like that I can’t adjust anymore in new cable. Please suggest me why I can’t get the adjustment space in new clutch cable. It is a sign of worn out clutch plates. Please help me out.
