[0011] (1) A vehicle-mounted mobile communication antenna device, when disassembling the device, the sealing cover is removed by rotating the sealing cover, thereby exposing the limit groove, and the limit block inside the limit groove is rotated so that the bottom of the limit block can be aligned with the rectangular hole inside the limit groove. Under the push of the spring, the shell pops up, and the limit block passes through the hole on the surface of the limit groove, so that the shell can be opened without the aid of external tools, thereby facilitating the disassembly of the shell of the antenna device.

[0012] (2) The vehicle-mounted mobile communication antenna device has connecting blocks installed on both sides of the antenna body, and the suction cup is fixed to the bottom of the connecting block by bolts and nuts, so that the antenna body can be fixed to the top surface of the vehicle by the suction cup. Since it is connected by the suction cup, it is more convenient to disassemble and replace the antenna body.

[0013] Therefore, the problem that the existing vehicle-mounted antenna shells are all connected by fixed connection or by screws, but the shells are not easy to be quickly disassembled during disassembly and maintenance is solved. BRIEF DESCRIPTION OF THE DRAWINGS
