The rear end of the horn antenna body 1 is provided with a mounting sleeve 5. The rear end of the upper bracket 2 is fixedly connected to the upper end of the mounting sleeve 5, and the bottom end of the lower bracket 3 is fixedly connected to the bottom end of the mounting sleeve 5. The coplanar waveguide-fed horn antenna body 1 is a prior art structure, and this part will not be described in detail here. Through the arrangement and cooperation of the upper bracket 2, the lower bracket 3 and the mounting sleeve 5, the coplanar waveguide-fed horn antenna body 1 can be stably supported, and the mounting sleeve 5 can be fitted and connected to the external antenna rod.

[0026] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, furthermore, the upper and lower left sides of the mounting sleeve 5 are integrally formed with fixed clamps 6, and the upper and lower ends of the front and rear sides of the mounting sleeve 5 are provided with guide grooves 7. The right side of the fixed clamps 6 is provided with movable clamps 8. Both the fixed clamps 6 and the movable clamps 8 are semi-circular structures, and the inner surface of the movable clamps 8 is integrally formed with several anti-slip protrusions 9. The upper and lower ends of the left front and rear sides of the movable clamps 8 are fixedly connected with guide strips 10, and the guide strips 10 are slidably connected to the guide grooves 7. The outer perimeter of the middle position of the movable clamps 8 is fixedly connected with a pull ring 11, and the middle left position of the pull ring 11 is fixedly connected with a connecting button 12. The left end of the connecting button 12 has a connecting groove 13. The middle left position of the fixed clamps 6 is fixedly connected with a fixing bracket 14. The fixing bracket 14 is a "U" shaped structure. The middle left position of the fixing bracket 14 has a screw hole 15, and a screw rod 16 is screwed into the screw hole 15. A knob 17 is fixedly connected to the left end, and a connecting shaft 18 is fixedly connected to the right end of the screw 16. Both the connecting shaft 18 and the connecting groove 13 are "convex" shaped structures, and the connecting shaft 18 and the connecting groove 13 are rotatably connected. The movable slip 8 can move relative to the fixed slip 6 and is guided and limited by the sliding cooperation between the guide strip 10 and the guide groove 7. In the tightened state, the movable slip 8 can cooperate with the fixed slip 6 to further lock and fix the mounting sleeve 5 and the external antenna mast. The anti-slip protrusions 9 on the inner surface of the movable slip 8 can further increase the friction between the movable slip 8 and the antenna mast to improve its locking effect. The pull ring 11 is used for the indirect connection between the movable slip 8 and the screw 16. The right end of the screw 16 and the knob 12 at the left end of the pull ring 11 are rotatably connected by the connecting shaft 18 and the connecting groove 13, so that the rotating screw 16 can drive the pull ring 11 and the movable slip 8 to move, thereby realizing the adjustment of the movable slip 8.

[0027] In this embodiment, the present invention has an upper bracket 2, a mounting sleeve 5, and a lower bracket 3 at the rear of the coplanar waveguide-fed horn antenna body 1. The mounting sleeve 5 has a fixed clip 6 and a movable clip 8 at both the upper and lower ends. During installation, the mounting sleeve 5 can be fitted over the external antenna mast. Then, through the arrangement and cooperation of the fixing bracket 14, screw 16, knob 17, connecting shaft 18, connecting button 12, pull ring 11, and guide strip 10, the anti-slip protrusion 9 can be moved and tightened relative to the movable clip 8, thereby realizing the convenient installation operation of the present invention. Similarly, the movable clip 8 can be moved back, which can realize the convenient disassembly of the present invention relative to the external antenna mast for subsequent maintenance operations. At the same time, the upper bracket 2, lower bracket 3, and fixed clip 6 at the rear end can provide stable support for the coplanar waveguide-fed horn antenna body 1 at the front end, making it more efficient.

[0028] The usage process and working principle of this utility model are as follows: In use, the mounting sleeve 5 at the rear end of the coplanar waveguide-fed horn antenna body 1 is fitted onto the external antenna mast. Then, the screw 16 is rotated to the left by the knob 17. Since the right end of the screw 16 and the left end of the pull ring 11 are connected by the connecting knob 12 through the connecting shaft 18 and the connecting groove 13, the screw 16 rotating to the left can drive the pull ring 11 and the movable clip 8 to move and tighten to the left. The guide bar 10 moves relative to the guide groove 7 for guidance and limitation. Through the cooperation of the tightened movable clip 8 and the fixed clip 6, the mounting sleeve 5 and the external antenna mast can be further locked and fixed, thereby completing the fixed installation of this utility model. After that, the coplanar waveguide-fed horn antenna body 1 is connected to the external wiring for use.

[0029] Similarly, during disassembly, the screw 16 can be rotated to the right by the knob 17. Since the right end of the screw 16 and the left end of the pull ring 11 are connected by the connecting knob 12 through the connecting shaft 18 and the connecting groove 13, the screw 16 rotating to the right can drive the pull ring 11 and the movable latch 8 to move back to the right. The guide bar 10 moves relative to the guide groove 7 to guide and limit the movement, thereby releasing the locking and fixing state of the mounting sleeve 5 relative to the external antenna rod. Then, the mounting sleeve 5, the lower bracket 3, the upper bracket 2, and the coplanar waveguide-fed horn antenna body 1 can be removed from the external antenna rod as a whole, which is convenient and quick.
