It still appears something like a ball/bullet extractor to me, but I'm no expert!
It looks like the bit in the centre could be reversed and screwed into the handle part.
If the 'tweezers' are spring-loaded, (made of spring steel) they will expand as the centre tube is slid upwards towards the threaded part, and as the tube is slid back down to-wards the tweezer tips, the spring pressure is increased and they will grip an object securely.
Best,
Richard.
