[0008] The frame connector has a concave second arc segment and a third arc segment. The first base is connected to the arc transition segment through the second arc segment, and the fourth base is connected to the arc transition segment through the third arc segment. The second arc segment and the third arc segment further reduce the weight of the frame connector.

[0009] The weight-reducing groove includes a first groove and a second groove that are smoothly connected. The first groove has a gradually changing groove width structure, with the groove width being the smallest at the end of the first groove near the first arc segment and the groove width being the largest at the end of the first groove near the arc transition segment.
