Thanks for the quick reply.

Here is the ad photos.

I just can't trust this photo. The arrows for the screw cap and spring are wrong. And when I opened it, the spring and the fuse switched in position.

Here are my questions:

1. There are two curved copper pieces. It supposed to be connected as negative pole. One of them connecting to the positive pole through an electric resistance and the RED light, one of them is stand alone. Which one should I connect to?

It shouldn't matter. Use whichever one is easier to solder to. One of them is attached to the LED so that whenever the adapter is plugged in, the LED's circuit is completed and it lights up.

2. Should the fuse connect to the "contact head" or the spring connect to the "contact head" ?

Ideally the fuse connects to the contact head first, so when you remove the cap the spring pushes the fuse out so you don't have to shake the fuse out. Otherwise it doesn't matter too much,

Thanks
