Hi Abdullah
With regard to your qustion, when you say you can't find the fuse holder, do you mean you've pushed it into machine and can recover it? if this is what you mean, you will have to strip down the motor cover and simply screw it back in.
If you are askig where you can find a new replacement, all you need to do is go to eBay and search for a 'panel mount fuse holder' and you will find a large choice.
