[0002] Transmitting or receiving antennas working in the wave bands of meter waves, centimeter waves, millimeter waves, etc. are collectively referred to as microwave antennas. Microwaves are mainly propagated by space waves. In order to increase the communication distance, the antenna is set up higher. The Chinese utility model patent, authorization announcement number "CN212083273U", discloses a moisture content measurement device based on the microwave antenna method, including a moisture content measurement body, a connecting line, a fixed shell and two pins, one end of the two pins are fixedly connected to the top of the fixed shell, one end of the connecting line is plugged into the middle of the top of the moisture content measurement body through a connector, and the other end of the connecting line is electrically connected to the two pins inside the fixed shell through the connector. An annular wire collection groove is provided in the middle of the outer wall of the fixed shell, and a limiting mechanism for limiting the connecting line is provided on one side of the top of the fixed shell.

[0003] The above technical scheme, when using the moisture content measuring body, allows the staff to place four fingers in the inner cavities of the four finger grooves respectively, hold the U-shaped plate tightly with their hands, and pull the protective cover hard to separate the two card plates from the two card grooves. At the same time, the two pins are pulled out from the inner cavities of the two needle grooves respectively, thereby bringing the moisture content measuring body into contact with the object, making it easier for the staff to hold the fixed shell tightly, and improving the efficiency of moisture content measurement. However, the above technical scheme still has certain defects. For example, the above device pulls out the two pins from the inner cavities of the two needle grooves respectively, thereby bringing the moisture content measuring body into contact with the object, and improving the efficiency of moisture content measurement. However, when the moisture content measuring body needs to be disassembled for maintenance, the staff needs to use tools to disassemble it, which greatly reduces the disassembly efficiency of the equipment and increases the workload of the staff.
