[0024] The base 1 is provided with a rotating box 7, the rotating shaft 21 is rotationally connected with the base 1 through the rotating box 7, the rotating shaft 21 is fixedly arranged with a first bevel gear 71, the first bevel gear 71 is located inside the rotating box 7, the side wall of the rotating box 7 is rotationally arranged with a connecting shaft 8, one end of the connecting shaft 8 close to the rotating box 7 is provided with a second bevel gear 81, the second bevel gear 81 is meshed with the first bevel gear 71, the other end of the connecting shaft 8 away from the rotating box 7 is provided with a handle 82.

[0025] Rotating the rotating handle 82 drives the connecting shaft 8 to rotate, and the second bevel gear 81 on the connecting shaft 8 rotates accordingly. Since the second bevel gear 81 is in meshing relationship with the first bevel gear 71, the rotation of the second bevel gear 81 drives the first bevel gear 71 to rotate, and then the rotating shaft 21 fixed with the first bevel gear 71 rotates, finally the control box 2 rotates around the rotating shaft 21, and the plate-shaped antenna 3 is adjusted in angle.

[0026] The control box 2 is provided with two groups of mounting mechanisms on the two side walls, and is connected with the plate-shaped antennas 3 on the two sides respectively. The stability and reliability of the installation of the plate-shaped antennas 3 are improved, and it is ensured that the plate-shaped antennas 3 will not be loose or displaced during the working process, and the overall performance of the antenna is improved.

[0027] The control box 2 is provided with a hinged door 22, and the hinged door 22 is provided with a handle 23.
