[0008] Preferably, the fixing block is a rectangular block, the wire hole is a circular hole, the wire hole is located at the center of the fixing block, and the diameter of the wire hole is larger than the diameter of the antenna.

During use, the base and the bottom plate are connected by two connecting screws, and the double-sided tape is torn off to adhere the foam to the carrier, which can increase the distance between the base and the carrier, effectively reducing the influence of the antenna by the metal carrier below. The setting of the bottom plate is to facilitate the installation and separation of the base and the foam, achieving the purpose of easy use. Brief Description of the Drawings
