I don't think that there is an easy way of fixing that it looks like the entire area where you would clamp your lead has been broken. Without two clamps you're not going to be able to use your atomizer it has to have connection points into places one in the positive one in the negative at a minimum. I don't know If there's a way to solder it or something cuz I don't know that much about that stuff I don't know how that would work. There's a possibility also that I'm seeing something missing on the picture that isn't actually as bad as it seems but it looks pretty bad
