[0002] Antennas are essential devices in wireless communication equipment. They convert electromagnetic waves in space into electrical signals, or vice versa, and play an important role in wireless communications.

[0003] In current wireless communication devices, internal antennas are mostly used for portability and aesthetics, but some devices with higher signal requirements, such as vehicle-mounted antennas, walkie-talkie antennas, router antennas, etc., still use external antennas. These devices mostly use whip antennas, or whip antennas in a plastic shell. However, these devices with external antennas take up a large space and are not convenient to carry. Therefore, many devices now use foldable external antennas, that is, the antenna is opened when in use and folded when not in use, which can reduce the space occupied by the device.

[0004] Existing patent documents, such as the Chinese patent document with publication number CN210350062U, are an antenna device for electronic communications, which consists of a base, a bottom antenna and a top antenna. The bottom antenna is rotatably connected to the base via a bottom rotating shaft on the top surface of the base, and the top antenna is rotatably connected to the bottom antenna via a top rotating shaft at the bottom end. The top rotating shaft and the bottom rotating shaft are connected by a pull rope. When the bottom antenna rotates, a part of the pull rope is wound around the bottom rotating shaft, driving the top rotating shaft to rotate, thereby causing the top antenna to rotate toward the bottom antenna. However, the bottom antenna shell and the top antenna shell of the device are both integrated, and it is not convenient to install a wire antenna inside. That is, the prior art has the problem of inconvenient installation of the wire antenna. Utility Model Content
