[0053] In the embodiment, the fastener 15 is a screw, a screw or a bolt. When the fastener 15 is a screw, a fixing hole 142 is formed in the end cover 14, and a blind hole 12242 is formed in the rotating column 1224.

[0054] In another embodiment of the present application, in combination with Figure 4 and Figure 5 As shown, the provided end cover 14 of the antenna 10 is provided with a limiting column 141 close to the surface of the rotating column 1224. The limiting column 141 is located on the side of the fastener 15, the rotating column 1224 is provided with a limiting hole 12241, and the limiting column 141 is inserted into the limiting hole 12241.

Specifically, the number of the limiting column 141 can be two, three or more than three, and the specific number can be selected according to actual needs, which is not limited herein. For example, the number of the limiting column 141 is two, and the two limiting columns 141 are respectively located on the opposite sides of the fixing hole 142. In this way, the two limiting columns 141 are respectively inserted into the two limiting holes 12241, so as to ensure the alignment of the fixing hole 142 and the blind hole 12242, and the installation of the fastener 15 is more convenient and fast.
[0056] In another embodiment of this application, combined with Figure 4 and Figure 5 As shown, the base 122 of the provided antenna 10 has a mounting surface 1222 parallel to the axis of the housing 11. A rotating column 1224 is disposed on the mounting surface 1222. The mounting surface 1222 is provided with a plugging protrusion 1223. The fixing seat 13 is provided with at least two plugging grooves 131. The plugging grooves 131 are arranged in a circular array with the axis of the rotating hole 132 as the center.

When the insertion protrusion 1223 is inserted into the insertion groove 131, the rotating column 1224 rotates within the rotating hole 132, thus fixing the angle of the antenna 10 and improving the stability and reliability of the antenna 10. In addition, when the antenna 10 needs to be adjusted, simply loosen the fastener 15 to move the rotating column 1224 out of the rotating hole 132 a certain distance, separating the insertion protrusion 1223 from the insertion groove 131. Then, rotate the antenna 10 to the preset angle, insert the insertion protrusion 1223 back into the corresponding insertion groove 131, and finally lock the fastener 15. This achieves the angle adjustment of the antenna 10.
[0057] In this embodiment, the number of insertion protrusions 1223 can be two, three, four or more, and the insertion protrusions 1223 are also in a circular array.
