I am sorry to inform you, but your picture looks like your hotend has a broken heatbreak. The heatbreak is the screw that connects the heater block with he coldend.
Your first picture clearly shows that the tp 2 or 3 windings of the screw are ripped off. Probably from tightening the nut against the codend carriage and this way applying tremendous force - the lower picture hints that it was tightened far too strong.
You are lucky however, as replacement heatbreaks are easy to come by and cheap.
