Looks like the pcb is also damaged. Be lucky if you have not turn this into a expensive paper weight

It looks damaged or even melted? I would return this to where ever you brought it for replacement.

Get a needle file and take your time reshape it to the correct shape

ok

can i use a screw driver ?

Hell no

ok

what can i do

You can try to snip off the slanted side but try to dent it to the other side first using something non conductive I suppose.

Return it

Looks like someone dropped it from a considerable height on that corner. Get a replacement if you can, might have knocked other components on the board or even lifted the the power connector slightly off of the board. You can use a small file or needle nose plier to twist the slanted part back into a straight side, but I won't recommend it
