US Patent 10439346 Elastic piece structure and adapter

An elastic piece structure and an adapter are disclosed. The elastic piece structure includes a mounting portion, a T-shaped curved elastic piece and an anti-falling structure. The T-shaped curved elastic piece includes a first elastic portion bending outward and a first abutting portion abutting against a panel. One end of the first elastic portion is connected to the mounting portion and the other end of the first elastic portion is connected to a middle part of the first abutting portion. The anti-falling structure is disposed on a side of the mounting portion. The elastic piece structure uses the T-shaped curved elastic piece and the anti-falling structure and is fixed without screws, alleviating shaking between a product and the panel and ensuring a firm attachment between the product and the panel.
