The positioning column 6 can be used for up and down limiting and guiding of the limiting shell 9. The bottom end of the positioning column 6 is provided with a combined plate 7 which is penetrated through in a threaded manner. The combined plate 7 can be used for arranging the first spring 8 outside the positioning column 6. The first spring 8 can be elastically pushed to contact the bottom end of the limiting shell 9 and the shell 1 by the elastic action of the first spring 8. The front side of the L-shaped limiting shell 9 can be located on the front side of the shell 1 at this time, and can be used for limiting and blocking the antenna main body 4 arranged inside the shell 1.
