Bracket structure and antenna fixing device
A bracket structure includes a body, two retaining walls, at least one first stop part, and at least one second stop part. The two retaining walls are respectively connected to two ends of the body, and respectively form an accommodating groove with the body, and a virtual connection line is extended between the two accommodating grooves. At least one first stop part protrudes from the body towards the virtual connection line. At least one second stop part protrudes from at least one of the two retaining walls towards the virtual connection line, and at least one first stop part and the at least one second stop part are separated by a clamping space in a direction. Thus, the bracket structure fix the antenna module without using any fixing components.
