The connecting shell is a hollow structure. The cavity inside the connecting shell is connected to the third mounting cavity. One end of the mounting shell of the first connector is rotatably connected to the connecting shell and located in the first mounting cavity.

5. The quick-release antenna according to claim 4, characterized in that, The mounting shell includes a mounting sleeve and an inner core. The mounting sleeve is a hollow structure. The connecting shell is sleeved on the outer side of the mounting sleeve and rotatably connected to the mounting sleeve. The first port of the mounting sleeve is connected to the inner core through an elastic element. A second mounting cavity for mounting a crown spring is formed between the mounting sleeve and the outer side of the inner core. The second port of the mounting sleeve is used to connect to a second connector. The inner core has a hollow structure and is inserted into the internal cavity of the connecting shell and fixedly connected to the inner wall of the connecting shell.
