The upper end surface of the supporting seat 15 is provided with a slot, and the specifications of the slot match the antenna 6, so that the supporting seat 15 is compatible with the structure of the antenna 6 to avoid deviation.

[0031] like Figure 3-Figure 5As shown, the slide 8 is of a U-shaped structure, and the slide 8 is slidably connected to the slide rail 7 to ensure that the connection effect between the slide 8 and the bearing rod 4 is stable; a concave cavity 9 is opened in the middle of the slide 8, and a gear 10 is arranged in the middle of the concave cavity 9. A driving motor 11 is fixedly installed on one side of the gear 10 of the slide 8, and a bearing seat 12 is installed on the other side of the gear 10 of the slide 8 through a slot. The driving motor 11 can drive the gear 10 to rotate, thereby driving the slide 8 to perform displacement operations; the driving motor 11 is fixedly connected to the gear 10, and the bearing seat 12 is rotationally connected to the gear 10, and the bearing seat 12 can provide a stable support effect for the rotational movement of the gear 10; a tooth groove 16 is opened at the lower end of the bearing rod 4 corresponding to the gear 10, and the tooth groove 16 matches the specifications of the gear 10 and meshes with it, ensuring that the power transmission effect of the gear 10 is stable.
