Detailed Description
The technical solutions of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not limited to the present invention.

In the present embodiment, the base station antenna having the phase shift driving mechanism includes a reflection plate 10, a phase shifter unit 20 fixed on the reflection plate 10, and a phase shift driving mechanism 30 driving the phase of the phase shifter unit 20.

In the embodiment, the holder fixing hole 332 is located between the holder pivot hole 331 and the reflective plate 10. Since the arrangement direction of the fixing seat pivot holes 331 and the fixing seat fixing holes 332 is perpendicular to the reflection plate 10, when two or more fixing seats 330 are provided, the structures of the fixing seats 330 can be the same, and further, when the fixing seats 330 are manufactured, a mold can be used for manufacturing, so that the structure is simplified, and the production efficiency is improved.
The pivot base 340 has a pivot hole 341 and a pivot fixing hole 342, and the arrangement direction of the pivot hole 341 and the pivot fixing hole 342 is perpendicular to the reflective plate 10. In the embodiment, the pivot hole 342 is located between the pivot hole 341 and the reflective plate 10. Since the arrangement direction of the pivoting holes 341 and 342 is perpendicular to the reflective plate 10, when two or more pivoting seats 340 are provided, the pivoting seats 340 can have the same structure, and further, when the pivoting seats 340 are manufactured, a mold can be used for manufacturing, thereby simplifying the structure and improving the production efficiency.
Two ends of the screw rod 310 are respectively pivoted in the fixing base pivoting hole 331 of the fixing base 330 and the pivoting base pivoting hole 341 of the pivoting base 340, so as to be pivoted on the fixing base 330 and the pivoting base 340 for driving the connecting base 360 to move.
Two ends of the guide rod 320 are fixed in the fixing base fixing hole 332 of the fixing base 330 and the pivoting base fixing hole 342 of the pivoting base 340, respectively, so as to be fixed on the fixing base 330 and the pivoting base 340 for guiding the connecting base 360 to move.
