Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of these features. In the description of this application, unless otherwise specified, "a plurality of" means two or more.

[0027] An antenna is an electrical device for transmitting or receiving radio waves and is a key component in a wireless communication system. A higher operating frequency of the antenna indicates higher sensitivity to an angle change. A related adjustment mechanism cannot precisely adjust an antenna angle, and cannot self-lock after adjustment, easily leading to deviation and low adjustment precision. This brings much inconvenience to users and affects use experience and effect. There are also some antenna angle adjustment mechanisms on the market that can support angle fine-tuning. The antenna angle adjustment mechanism usually includes a worm gear structure and a motor, often with a complex structure and high costs.

The first adjustment mechanism 200 includes a first bolt 210 and a first transmission assembly 220 connected to the first bolt 210, and the first transmission assembly 220 is connected to the antenna mounting bracket 100 to cause the first bolt 210 to drive, via the first transmission assembly 220, the antenna mounting bracket 100 to rotate around the first rotating shaft 230. The second adjustment mechanism 300 includes a second bolt 310 and a second transmission assembly 320 connected to the second bolt 310, and the second transmission assembly 320 is connected to the antenna mounting bracket 100 to cause the second bolt 310 to drive, via the second transmission assembly 320, the antenna mounting bracket 100 to rotate around the second rotating shaft 330. An axis of the first rotating shaft 230 and an axis of the second rotating shaft 330 are perpendicular to each other.

[0029] When the adjustment apparatus is in an upright state, an axial direction of the first rotating shaft 230 is a horizontal direction, and the first adjustment mechanism 200 is configured to adjust a pitch angle of the antenna 10; and an axial direction of the second rotating shaft 330 is a vertical direction, and the second adjustment mechanism 300 is configured to adjust a horizontal angle of the antenna 10.

[0030] In some optional embodiments, the adjustment apparatus includes a first mounting bracket 400, and the first mounting bracket 400 is configured for connection to a supporting structure such as a wall or a holding pole.

During rotation of the first bolt 210, the first slider 222 can move along the axial direction of the first bolt 210, but cannot rotate along the axial direction under the limitation of the first sliding slot 221. In addition, the first slider 222 drives the antenna mounting bracket 100 to rotate around the first rotating shaft 230. In the above adjustment process, because the first bolt 210 is threadedly connected to the first slider 222, and has self-locking characteristics, hovering of the antenna mounting bracket 100 at any angle can be achieved.

[0033] In some optional embodiments, the adjustment apparatus includes a second mounting bracket 500, and the second mounting bracket 500 is disposed between the antenna mounting bracket 100 and the first mounting bracket 400.

In addition, one end of the second rotating shaft 330 is fixedly connected to the antenna mounting bracket 100, and the other end of the second rotating shaft 330 is rotatably connected to the second mounting bracket 500, so the antenna mounting bracket 100 rotates around the second rotating shaft 330 relative to the second mounting bracket 500.

During rotation of the second bolt 310, the second slider 322 can move along the axial direction of the second bolt 310, but cannot rotate along the axial direction under the limitation of the second sliding slot 321. In addition, the second slider 322 drives the antenna mounting bracket 100 to rotate around the second rotating shaft 330.
