[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] When the support rod 3 is in the deployed state, it will be placed horizontally. To ensure the stability of the support rod 3. By passing the knob column 6 through the fixed seat 2 and inserting it into the limit sleeve 5 and the support rod 3, the support rod 3 can be effectively fixed to prevent unnecessary bouncing or displacement during use. This knob column is designed very tightly and has good self-locking performance. When the support rod 3 is loosened, the knob column 6 can be reset, and it can remain fixed on the fixed seat 2 without falling off easily even under frequent disassembly and assembly.

[0021] When it is necessary to retract the support rod 3, only need to loosen the knob column 6 on the fixing base 2, and then the support rod 3 can be rotated to the required storage position. At this time, the support piece 7 installed on the support rod 3 will cooperate with the corresponding part on the fixing plate 9. In order to further fix this state, the connection with the support piece 7 can be achieved by locking the stud on the fixing plate 9, so as to ensure the stability and safety of the support rod 3 in the non-use state.

[0022] Please refer to Figures 1-5 In the embodiment of the present utility model, an omnidirectional antenna fixing device includes a base 1. A plurality of rotatable support rods 3 are provided on the outer peripheral surface of the base 1. The number of the support rods 3 is not limited. In this embodiment, preferably, the number of the support rods 3 is five, and the five support rods 3 are equally spaced on the outer peripheral surface of the base 1. The support rods 3 are connected to 1 through hinges, and the hinges limit the moving direction of the support rods 3 so that they can only move in the vertical direction. Secondly, in order to ensure that the support rods 3 can be firmly fixed at the required positions, fixing seats 2 with the same number as the support rods 3 are provided on the outer peripheral surface of the base 1. An upper fixing plate 9 is provided above the base 1. Studs for fixing the support piece 7 are provided on the fixing plate 9. The support piece 7 is fixed on the outer peripheral surface of the support rod 3. A plurality of studs with the same number as the support pieces 7 are installed on the fixing plate 9. Through holes for the studs to pass through are provided on the plurality of support pieces 7, which are configured to when the support rods 3 are fully retracted, the support pieces 7 will be combined with the fixing plate 9, so as to complete the locking of the support rods 3 and ensure the stability and reliability of the whole structure.

[0023] Please refer to Figure 1 and Figure 5 In an embodiment, preferably, a U-shaped groove is reserved on the upper end surface of the fixing seat 2. A limit sleeve 5 matching the U-shaped groove is installed on the outer peripheral surface of the support rod 3. A hinge support connected to the fixing seat 2 is installed at the end of the support rod 3 near the limit sleeve 5. A knob column 6 with an end that can be inserted into the limit sleeve 5 is installed on the fixing seat 2. Further, the fixing seat 2 not only has a U-shaped groove for restricting the support rod 3, but also has a hinge support for realizing the rotation function in cooperation with the support rod 3. During the assembly process, first, the end of the support rod 3 needs to be aligned and combined with the hinge support on the fixing seat 2, and then the two are locked with the knob column 6, so as to establish a rotating mechanism that only allows the support rod 3 to move in a single direction, ensuring the free movement and accurate positioning of the support rod in the vertical direction.

[0024] Please refer to Figures 1-4 In an embodiment, preferably, the fixing plate 9 is sleeved on the outer peripheral surface of the support rod 8, and the support rod 8 is installed on the upper end surface of the base 1.
