[0027] Before installing the indoor antenna 18, first install and fix the base 2 and the support rod 3. The base 2 is fixed to the wall or ceiling by fasteners such as screws and bolts, or fixed to the wall or ceiling by bonding, and the support rod 3 is fixed to the base 2. When installing the indoor antenna 18, first insert the insertion rod 4 into the installation hole 301 at the upper end of the support rod 3, then the elastic fastener is buckled in the above-mentioned buckle hole 302 under the action of its own elastic force, and finally tighten the set screw 51, and the indoor antenna 18 can be locked in the axial groove 41, which is convenient and quick; when the insertion rod 4 is inserted into the support rod 3, the above-mentioned axial groove 41 can play a guiding role, so that the elastic fastener is accurately buckled into the buckle hole 302. After the locking set screw 51 is tightened, the cooperation of the axial groove 41 and the set screw 51 can prevent the indoor antenna 18 from rotating relative to the support rod 3, which is conducive to maintaining the stability of the orientation of the indoor antenna 18. When removing the indoor antenna 18, first loosen the set screw 51, then press the elastic fastener to disengage it from the buckle hole 302 on the support rod 3, and then pull the insertion rod 4 on the indoor antenna 18 upwards, which is very convenient.

[0028] There are several solutions for installing the set screw 51 on the support rod 3. First, a nut 52 is provided on the outer wall of the support rod 3. The nut 52 is a kind of nut. The set screw 51 passes through the nut 52 and engages with the nut 52. Second, a screw hole is provided on the outer wall of the support rod 3. The set screw 51 passes through the screw hole and engages with the screw hole.

[0029] Reference Figure 3 In a preferred embodiment of the present invention, a receiving cavity 42 is provided on the insertion rod 4, and a first opening 421 and a second opening 422 communicating with the receiving cavity 42 are provided on the outer wall of the insertion rod 4. The elastic fastener includes a base 61 accommodated in the receiving cavity 42, and an elastic reset member 62 capable of pushing the base 61 upward by elastic force. The base 61 is provided with a buckle 611 extending from the first opening 421 and buckled in the buckle hole 302. The base 61 is also provided with a button 612 extending from the second opening 422. When the button 612 is pressed, the buckle 611 moves downward and disengages from the buckle hole 302.

[0030] In some solutions of the present invention, other structures may be used to replace the above-mentioned elastic fastener, such as a spring top bead or an elastic buckle that can be snapped into the buckle hole 302.

[0031] Furthermore, a limiting step 43 abutting against the upper end surface of the support rod 3 is provided on the outer side wall of the insertion rod 4. With such a design, the maximum insertion depth of the insertion rod 4 can be limited, so that the elastic fastener can be accurately fastened into the buckle hole 302.

When the user uses such a bracket structure to install the indoor antenna 18, there are two installation modes. Mode 1: When conditions permit, try to install the fastening assembly 8 between the second mounting hole 202 and the first mounting hole 306, and then lock the fastening assembly 8, so that the entire bracket structure can remain stable for a long time. Mode 2: When the fastening assembly 8 cannot be installed at the second mounting hole 202, or when installing it at the second mounting hole 202 will make the indoor antenna 18 not in a good direction, the fastening assembly 8 can be installed at the arc hole 201, and the support rod 3 can be rotated to a suitable position, and then the fastening assembly 8 can be locked. In the case of moving, the entire bracket needs to be removed and then reinstalled in another location. At this time, the fastening assembly 8 can be unlocked, and then the support rod 3 can be rotated to make the indoor antenna 18 face in a better direction, and then the fastening assembly 8 can be locked.
