The operation principle of the fixing mechanism 36 will be described in detail below. Please refer to FIG. 1 , FIG. 3 and FIG. 4 , and FIG. 3 and FIG. 4 respectively illustrate the first bracket 32 , the second bracket 34 and the fixing according to the embodiment of the present invention. The mechanism 36 is in a schematic view of the components in different assembled states. As shown in FIGS. 1 , 3 , and 4 , the first bracket 32 is first inserted into the second bracket 34 from the position shown in FIG. 1 until the first bracket 32 is located as shown in FIG. 3 . So far, the first fixing structure 321 of the first bracket 32 is aligned with the second fixing structure 341 of the second bracket 34. Then, the sleeve member 42 of the fixing mechanism 36 is disposed on the first fixing structure 321 of the first bracket 32 and the second fixing structure 341 of the second bracket 34 until the elastic sleeve 44 of the fixing mechanism 36 is exposed to the first bracket. 32 and the second bracket 34 (as shown in Fig. 4). Thereby, the fixing mechanism 36 can restrict the first bracket 32 from being detached from the second bracket 34.

Referring to FIG. 5 and FIG. 6 , FIG. 5 is a cross-sectional view of the first bracket 32 , the second bracket 34 and the fixing mechanism 36 in an assembled state according to an embodiment of the present invention, and FIG. 6 is a first bracket according to an embodiment of the present invention. 32. A cross-sectional view of the component in which the second bracket 34 and the fixing mechanism 36 are in a fixed state. As shown in FIG. 5 and FIG. 6, when the user wants to fix the first bracket 32 and the second bracket 34 of the antenna device 30, first, the handle portion 485 of the handle member 48 is rotated along one of the ones shown in FIG. The direction R is pulled to drive the rotating shaft portion 481 and the pressing cam 483 to rotate relative to the pivot member 46. Further, during the rotation of the rotating shaft portion 481 and the pressing cam 483 relative to the pivoting member 46, the pressing cam 483 can abut against the stopping portion 423 of the sleeve member 42 and then press down on the sleeve member 42. The stop portion 423, at which time the stop portion 423 of the sleeve member 42 can be pushed against the lower pressing cam 483 of the handle member 48, thereby driving the sleeve portion 421 of the sleeve member 42 along a first direction X1. The elastic bushing 44 is extruded.

On the other hand, when the handle portion 485 of the handle member 48 is pulled in the rotational direction R as shown in FIG. 5, the lower pressing cam 483 of the handle member 48 is slidable along the lower surface of the stopper portion 423 of the sleeve member 42. At this time, by pressing the cam 483 and the relative movement of the stopper portion 423 of the sleeve member 42 under the handle member 48, the pressing cam 483 can drive the rotating shaft portion 481 of the handle member 48 to be opposite to the first direction X1. The second direction X2 moves. In addition, since the rotating shaft portion 481 is pivotally connected to the pivoting member 46, the rotating shaft portion 481 of the handle member 48 can be pulled in the rotational direction R of the handle member 48 in the rotational direction R as shown in FIG. The driving pivot member 46 drives the lever member 38 to move in the second direction X2. At this time, the limiting member 40 can be pulled by the lever member 38 to press the elastic sleeve 44 in the second direction X2.

In other words, during the process of pulling the handle portion 485 of the handle member 48 in the rotational direction R as shown in FIG. 5, the handle member 48 can simultaneously drive the sleeve member 42 to move in the first direction X1 and pull the limit. The member 40 moves in a second direction X2 opposite to the first direction X1. Thereby, the limiting member 40 can co-extrude the elastic sleeve 44 with the sleeve portion 421 of the sleeve member 42 to cause the elastic sleeve 44 to be radially deformed (as shown in FIG. 6). At this time, the elastic sleeve 44 which is radially deformed cannot pass through the first fixing structure 321 of the first bracket 32 and the second fixing structure 341 of the second bracket 34, in other words, the elastic sleeve 44 which is radially deformed is generated. The first fixing structure 321 and the second fixing structure 341 are engageable.

In the process of the above-mentioned handle member 48 driving the sleeve member 42 and the limiting member 40 to press the elastic sleeve 44, the pressing cam 483 of the handle member 48 can push against the sleeve portion of the sleeve member 42. 421, the sleeve portion 421 is pressed down on one side of the first bracket 32 and the second bracket 34, and the limiting member 40 is simultaneously pulled and pressed together with the elastic sleeve 44 to the first bracket 32 and the second The other side of the bracket 34. Thereby, the fixing mechanism 36 can clamp the first bracket 32 and the second bracket 34 to firmly mount the first bracket 32 on the second bracket 34. In this way, the fixing mechanism 36 can fix the first bracket 32 and the second bracket 34 of the antenna device 30 so that the antenna element 33 can be stably disposed on the first bracket 32 and the second bracket 34 to receive the antenna signal.

It is worth mentioning that the application of the fixing mechanism 36 is not limited to the above embodiment.

As shown in FIG. 7 and FIG. 8, the main difference between the antenna device 30' and the antenna device 30 described above is that a bridge structure 323 is formed on one of the first brackets 32' of the antenna device 30' for bridging. One of the antenna devices 30' is a second bracket 34'. Therefore, the first bracket 32' and the second bracket 34' of the antenna device 30' can achieve a pre-positioning effect when assembled, so that the subsequent fixing mechanism 36 fixes the first bracket 32' and the second bracket 34'. The components of the embodiment having the same reference numerals as in the above embodiments have the same structural design and function principle, and are not described herein for brevity.

In addition, referring to FIG. 9, FIG. 9 is a schematic diagram of components of an antenna device 30" according to another embodiment of the present invention. As shown in FIG. 9, the antenna device 30" is different from the antenna device 30 described above. The antenna element 30' has one dish shape, that is, the antenna element 33' of the antenna device 30" is a dish antenna, and the antenna device A 30" receiver bracket 32" can be used to support the antenna element 33'. In this embodiment, the securing mechanism 36 can be used to secure the antenna element 33' and the receiver bracket 32", and the securing mechanism 36 can be used to secure the receiver bracket 32" with the support tube bracket 34. The components of the embodiment having the same reference numerals as in the above embodiments have the same structural design and function principle, and are not described herein for brevity.

Compared with the prior art, the fixing mechanism of the present invention uses the handle member to push against the sleeve member when rotating, and drives the pivot member to drive the rod member, thereby pulling the limiting member to make the limiting member and the sleeve member co-squeeze elastically. The sleeve further causes the elastic sleeve to be radially deformed to be engaged with the first fixing structure of the first bracket and the second fixing structure of the second bracket. In other words, the fixing mechanism of the present invention does not need to use the screw to lock the first bracket and the second bracket, and the fixing mechanism of the present invention can fix the first bracket and the second bracket only by rotating the handle member, and the installation process is relatively simple. It is easy to install and use.
