The fixing seat 2 includes two, and circular holes 201 are arranged on the two fixing seats 2. The adapter 3 is fixedly connected to the installation shaft 4, and the two ends of the installation shaft 4 are respectively inserted into the corresponding side circular holes 201 and slidably connected to the inner wall thereof. The limit assembly connects the antenna body 1 and the adapter 3, and the limit assembly includes a pin 5, a button A6 and a spline 7. A keyway 202 connected to the circular hole 201 on one side of one of the fixing seats 2 is provided away from the other fixing seat 2. The pin shaft 5 is a non-cylindrical shaft, and the pin shaft 5 is located in the installation shaft 4 and slidably connected thereto. The two ends of the pin shaft 5 are respectively connected to the button A6 and the spline 7, wherein the spline 7 is located in the keyway 202 and meshes therewith. A slide groove is provided in the installation shaft 4, and the button A6 is located in the slide groove and slidably connected thereto. A spring 8 is provided in the slide groove, and the two ends of the spring 8 abut against the inner wall of the slide groove and the button A6, respectively. The angle adjustment and fixation of the antenna body 1 are completed by locking and unlocking the limit assembly. The semi-ring A9 is integrally connected to the adapter 3, one end of the semi-ring A9 is rotatably connected to one end of the semi-ring B10, and the other end of the semi-ring A9 is connected to the other end of the semi-ring B10 through a quick release assembly. The quick release assembly includes an insert rod 11 and a wedge-shaped block 12. A slot 901 is provided on the semi-ring A9, and a slot 902 connected to the slot 901 is provided on the semi-ring A9, and the slot 902 is perpendicular to the slot 901. The insertion rod 11 is connected to the semi-ring B10, and the wedge-shaped block 12 is inserted into the insertion rod 11 and slides therewith, and a tensioning member for pushing the wedge-shaped block 12 outward is provided in the insertion rod 11. When the insertion rod 11 is inserted into the slot 901, the wedge-shaped block 12 is inserted into the slot 902. A button B903 is provided on the semi-ring A9, and the button B903 enters and exits the slot 902 and is slidably connected therewith. One end of the sliding rod 13 is inserted into the interior of the semi-ring B10 along the inner wall thereof and is slidably connected therewith, and the sliding rod 13 is rotatably connected to the movable plate 14, and the distance between the two ends of the movable plate 14 is greater than the thickness of the semi-ring A9. The driving assembly includes a screw 16. A guide rod is set on the semi-ring B10, and one end of the sliding rod 13 away from the movable plate 14 is inserted into the guide rod and slidably connected thereto, one end of the screw rod 16 is connected to the handle and the other end is inserted into the guide rod and rotatably connected thereto, and the screw rod 16 is inserted into the sliding rod 13 and spirally connected thereto, and a flexible anti-skid pad 15 is set on the side of the movable plate 14 away from the sliding rod 13, and the driving component drives the sliding rod 13 and the movable plate 14 to slide.

[0027] In this embodiment, during the actual installation, half ring A9 is clamped on the electric pole or the mounting column, and then half ring B10 is rotated until the insertion rod 11 is inserted into the slot 901 and the wedge-shaped block 12 is clamped into the slot 902. At this time, the openings of half ring A9 and half ring B10 are closed, and then the screw 16 is rotated to drive the sliding rod 13 and the movable plate 14 to approach the mounting column until they are tightly pressed. Since the mounting column may have a certain taper, the movable plate 14 automatically flips when it approaches the mounting column, increasing its contact surface with the mounting column, and at the same time, the sliding friction between it and the mounting column is increased through the flexible anti-skid pad 15 connected to it, thereby effectively preventing the device from sliding up and down or rotating horizontally on the mounting column. When it is necessary to remove the device, the button B903 can be pressed to retract the wedge-shaped block 12 into the insertion rod 11, and the half ring B10 can be opened. When it is necessary to adjust the signal transmission elevation angle of the directional antenna, only the button A6 needs to be pressed. The button A6 pushes the pin shaft 5 and the spline 7 and causes the spline 7 to slide out of the key slot 202. At this time, the pitch angle of the antenna body 1 can be adjusted. After adjustment, the button A6 is released. The spline 7 is re-inserted into the key slot 202 under the tension of the spring, thereby fixing the angle of the antenna body 1.
