A mounting device for easy mounting of a wireless device includes a clamping structure configured to clamp a support frame. The clamping structure includes a base including an upper surface and a lower surface, a first clamping part rotatably connected to the base, a second clamping part rotatably connected to the base, and a connection portion connected to the lower surface of the base. The wireless device is thus supported. The support frame is clamped between the upper surface and the first clamping part, and the support frame is clamped between the upper surface and the second clamping part.
