[0027] See also Figure 1-4 The utility model provides a technical solution: a combined small antenna, comprising:

[0028] A small antenna mounting frame 1, the inner wall of which is provided with four sliding grooves 13, a small antenna connecting seat 2 is slidably mounted inside the small antenna mounting frame 1, and a small antenna radiator 4 is fixedly mounted on the top of the small antenna connecting seat 2;

[0029] Antenna mounting structure, the antenna mounting structure is located on the small antenna mounting frame 1;

[0030] The antenna mounting structure includes a mounting block 10, an extruded triangular block 9 and a second spring 7.

[0033] The inner wall of the small antenna mounting frame 1 is provided with four positioning slots 5 , and the outer surface of the small antenna connecting seat 2 is fixedly connected with four positioning sliders 12 , and the four positioning sliders 12 are all slidably connected in the corresponding positioning slots 5 .

[0034] Furthermore, when using the device, the operator inserts the small antenna connector 2 into the small antenna mounting frame 1, so that the four positioning slide blocks 12 slide inside the corresponding positioning slide grooves 5. When the small antenna connector 2 moves downward inside the small antenna mounting frame 1, it will contact the four installation blocks 10, so that the four installation blocks 10 are guided on their inclined surfaces and retracted into the corresponding sliding grooves 13 and compress the corresponding second springs 7.

[0036] Through the cooperation of the third spring 17, the limiting post 18 and the limiting slide groove 16, the limiting post 18 can limit the combined pressure ring 3 to prevent the combined pressure ring 3 from moving downward due to accidental external contact, thereby further ensuring the stability of the small antenna connecting seat 2 after installation.

[0037] Working principle: The operator inserts the small antenna connection seat 2 into the small antenna mounting frame 1, so that the four positioning slide blocks 12 slide inside the corresponding positioning slide grooves 5. When the small antenna connection seat 2 moves downward inside the small antenna mounting frame 1, it will contact the four installation blocks 10, so that the four installation blocks 10 are guided on their inclined surfaces and retracted into the corresponding sliding grooves 13 and compress the corresponding second springs 7. After the small antenna connection seat 2 contacts the inner bottom wall of the small antenna mounting frame 1, the four installation blocks 10 will be reset under the support of the corresponding second springs 7 and be engaged with the corresponding installation slots 11, thereby facilitating the fixation of the small antenna connection seat 2. Installation, when the small antenna connector 2 needs to be disassembled, the operator pulls the limit post 18, so that the limit post 18 moves under the guidance of the limit slide groove 16 and compresses the third spring 17, and then directly presses the combined pressure ring 3 downward, and the combined pressure ring 3 moves downward to drive the four connecting columns 8. The downward movement of the four connecting columns 8 will drive the corresponding extrusion triangle blocks 9 to move downward and stretch the corresponding first spring 6. The downward movement of the four extrusion triangle blocks 9 will drive the corresponding installation blocks 10 to slide under the guidance of the inclined surface of the adjustment groove 19, so that the four installation blocks 10 are disengaged from the corresponding installation slots 11, thereby facilitating the quick disassembly of the small antenna connector 2.
