[0036] Example

[0037] Reference Figure 1-10 The utility model provides an embodiment: comprising a connecting seat 1 and a supporting arm 6, a rotating mechanism 2 is fixedly arranged at the center of the upper end surface of the connecting seat 1, the design of the rotating mechanism 2 is convenient for adjusting the rotation angle of the main body 5 to prevent the main body 5 from scratching other objects, the rotating mechanism 2 comprises an upper plate 201, a middle plate 203 and a lower plate 205, a fixing frame 3 is fixedly arranged at the center of the upper end surface of the upper plate 201, and a plurality of main bodies 5 are threadedly arranged on both sides of the outer wall of the fixing frame 3;

[0038] A connecting member 4 is threadedly provided on one side of the plurality of main members 5. The design of the connecting member 4 facilitates the connection between the two main members 5. A rotation groove 13 is provided through the center of the front and rear end surfaces of the connecting seat 1. The design of the rotation groove 13 facilitates the connection and fixation of the support arm 6 through the rotating shaft 17. A plurality of rebound grooves 14 are provided at the center of the inner wall of the two rotation grooves 13. The design of the rebound groove 14 facilitates the fixation of the No. 2 spring 15 and the insert 16.

[0039] A No. 2 spring 15 is fixedly provided at the center of the bottom end surface of multiple rebound grooves 14, and an embedding block 16 is fixedly provided at one end of multiple No. 2 springs 15. A flip groove 19 is opened at the center of the lower end of one side of the connecting seat 1. The design of the flip groove 19 facilitates the rotation of the support arm 6. A rotating shaft 17 is fixedly provided at the center of one side of the support arm 6, and multiple embedding grooves 18 are opened at the center of the outer wall of the rotating shaft 17 near both sides. Multiple embedding blocks 16 are respectively embedded in the multiple embedding grooves 18, and a mounting base 7 is fixedly provided on the other side of the support arm 6.

[0040] After the vibrator antenna is disassembled and transported to the installation site, the support arm 6 is first slightly rotated to a suitable position so that the fixing frame 3 is always facing upward during installation. The rotating shaft 17 squeezes the embedded block 16 during the rotation process, so that the embedded block 16 is disengaged from the embedded groove 18 to reduce the rotation resistance of the rotating shaft 17. During the rotation process, when the embedded block 16 and the embedded groove 18 are located on the same horizontal line, the embedded block 16 is embedded in the embedded groove 18 under the action of the second spring 15 to increase the resistance to the rotation of the rotating shaft 17, so that the rotation angle of the support arm 6 can be further limited by inserting the bolts along the screw holes 8 at the corresponding positions on the connecting seat 1 and the support arm 6, and then the symmetrical vibrator antenna is installed on the installation plane through the screw holes 8 on the mounting base 7;

[0041] When the installation space is relatively narrow and long, the main body 5 can be adjusted to face the long side of the narrow and long space by adjusting the rotating mechanism 2 to prevent the main body 5 from scratching the surrounding objects. When adjusting the rotating mechanism 2, first pull the upper plate 201 upward to make the fixing rod 204 disengage from the fixing groove 209 and embed into the through groove 206, then rotate the upper plate 201 to drive the middle plate 203 to rotate with the lower plate 205 as the reference through the bearing 207 and the fixing shaft 208, so that the fixing frame 3 rotates with the upper plate 201, and after adjusting the installation direction of the main body 5 to a relatively wide position, loosen the upper plate 201, so that the fixing rod 204 is embedded in the fixing groove 209 under the action of the No. 1 spring 202 to limit the rotation angle of the upper plate 201;

[0042] Then the main part 5 is threadedly set at the installation positions on both sides of the fixing frame 3, and then the connecting part 4 is threadedly set to the outer wall of the thread head 11 fixedly set on one side of the main part 5 through the thread groove 9 on one side of the connecting part 4, and multiple main parts 5 can be connected and installed through the connecting part 4 as needed. During the thread setting process, the thread groove 9 squeezes the clamping block 12. When the clamping block 12 and the clamping hole 10 are located on the same vertical line, the clamping block 12 is embedded in the clamping hole 10 to fix the position between the connecting part 4 and the main part 5, so as to prevent the thread from being worn by wind and sun, resulting in unstable connection between the main part 5 and the connecting part 4.

[0043] Working principle: By adjusting the direction of the installation points on both sides of the fixing frame 3 by adjusting the rotating mechanism 2, the main body 5 can be installed along the long side of the narrow space to prevent the main body 5 from scratching other objects, and through the design of the embedding block 16 and the embedding groove 18, resistance is generated during the adjustment of the angle of the support arm 6, which is convenient for the preliminary fixation of the rotation angle of the support arm 6, and the further fixation of the rotation angle of the support arm 6 through the connecting seat 1 and the screw hole 8 on the support arm 6, so that the oscillator antenna can adapt to different installation angles of the side wall and the roof through the rotation of the support arm 6, so that the fixing frame 3 is always oriented upward.
