It is not clear from your image the size of the battery that the clip is intended for. The Eagle library battery.lib contains some coin cell battery clips. You might be able to find a suitable component from this library, or you could create your own library for the part you are interested in.
thanks for your reply. It’s a triangular metal dome key but i still can’t find it under dome-key.lib . I am not quite experienced with eagle in creating a lib.
