So: You have a hedge trimmer you won't identify, an unidentified spring which has come from an unidentified part of the unidentified hedge trimmer.
The only response is "in an unidentified location"
You COULD, once you have worked out EXACTLY the model of the machine you have, do a simple Google search and see if you can find a manual, service manual, parts diagram or similar. Should only take a few minutes.
