<heading id="h0006"><b>DESCRIPTION OF EMBODIMENTS</b></heading>
<p id="p0025" num="0025">The technical solutions in embodiments of this application are clearly and thoroughly described below with reference to the drawings in embodiments of this application. It is clear that the described embodiments are only some embodiments of this application, rather than all embodiments. Based on embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort fall within the protection scope of this application.</p>
<p id="p0026" num="0026">The terms "first" and "second" are used only for the purpose of description, but cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. 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.</p>
<p id="p0027" num="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<!-- EPO <DP n="8"> --> 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.</p>
<p id="p0028" num="0028">An embodiment of this application provides an apparatus for adjusting an antenna. <figref idref="f0001">FIG. 1</figref> is a schematic diagram of a structure of an apparatus for adjusting an antenna according to an embodiment of this application, <figref idref="f0002">FIG. 2</figref> is a schematic diagram of a structure of an apparatus for adjusting an antenna according to an embodiment of this application, and <figref idref="f0003">FIG. 3</figref> is a cross-sectional view at A-A in <figref idref="f0002">FIG. 2</figref>.

The adjustment apparatus includes an antenna mounting bracket 100, a first rotating shaft 230, a second rotating shaft 330, a first adjustment mechanism 200, and a second adjustment mechanism 300.

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.<!-- EPO <DP n="9"> --></p>
<p id="p0029" num="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.</p>
<p id="p0030" num="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. One end of the first rotating shaft 230 is fixedly connected to the antenna mounting bracket 100, the other end of the first rotating shaft 230 is rotatably connected to the first mounting bracket 400, and the first bolt 210 can drive, via the first transmission assembly 220, the antenna mounting bracket 100 to rotate around the first rotating shaft 230 relative to the first mounting bracket 400.</p>
<p id="p0031" num="0031">It can be understood that the first transmission assembly 220 in embodiments of this application is configured to convert axial motion of the first bolt 210 into rotation of the antenna mounting bracket 100. The first transmission assembly 220 includes but is not limited to a slider and sliding slot assembly, a chain and sprocket assembly, a coupling, a gear, a gearbox, and the like. Optionally, the first transmission assembly 220 is a slider and sliding slot assembly, which has a simple structure and is cost-effective in production and maintenance. An example in which the first transmission assembly 220 is a slider and sliding slot assembly is used for description in the following embodiments.</p>
<p id="p0032" num="0032">Refer to <figref idref="f0001 f0002 f0003">FIGS. 1 to 3</figref>. The first transmission assembly 220 includes a first sliding slot 221 and a first slider 222 provided in the first sliding slot 221, the first sliding slot 221 is provided on the first mounting bracket 400, and the first slider 222 is threadedly connected to the first bolt 210 to cause the first bolt 210 to drive the first slider 222 to move in the first sliding slot 221 along only an axial direction of the first bolt 210. One end of the first rotating shaft 230 is rotatably connected to the first mounting bracket 400, the other end of the first rotating shaft 230 is fixedly connected to the antenna mounting bracket 100, and the antenna mounting bracket 100 is in<!-- EPO <DP n="10"> --> transmission connection to the first slider 222. 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.</p>
<p id="p0033" num="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.
