Technical Field

[0001] The utility model relates to the field of microphone brackets, in particular to a microphone connecting device with adjustable length. Background Art

[0002] When using a microphone for recording and picking up sound, in order to free the speaker's hands and improve the quality of the recording, the microphone is usually fixed on a bracket for use. In the Chinese utility model patent with the announcement number CN213818105U, a microphone bracket that is easy to adjust is disclosed. The distance between the microphone clamping mechanism and the mouth can be adjusted at will through a metal shaping hose. In this process, the telescopic rod is extended or contracted to support the metal shaping hose, and then the height is adjusted by the lifting rod, which can meet the use requirements of people of different heights. When adjusting, it is necessary to move the lifting rod up and down and fix it by adjusting the lock. When changing the length of the microphone and the distance between the mouth, it is necessary to adjust and lock the metal hose and the telescopic rod. The adjustment process is complicated, the adjustment time is long, and it is not convenient to use. For this reason, we designed a microphone connection device with adjustable length.
