[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example

[0031] Reference Figures 1 to 5, is an embodiment of the utility model, which provides a radio frequency combiner control device, mainly including a combiner body 1 and a plurality of resonant cavities 3 arranged at equal intervals in the combiner body 1. One side of the resonant cavity 3 is connected to the outside world for the convenience of user maintenance. When leaving the factory, one side of the combiner body 1 is also fixed with screws to an outer cover 2 that closes the resonant cavity 3. An axial-rotating resonator 4 is placed in the resonant cavity 3, and the axial-rotating resonator 4 can be a coaxial resonator / helical resonator / a combination of the two resonators. One end of the axial-rotating resonator 4 is fixed to the inner wall of the resonant cavity 3, and a first spring 5 is fixed to the upper end of the axial-rotating resonator 4, and one end of the first spring 5 is in conflict with the top wall / bottom wall of the resonant cavity 3.

[0032] In addition, the outer wall of the combiner body 1 is also attached with a plurality of torsion bars 6 and limit bars 7 corresponding to each resonant cavity 3, and one end of the torsion bar 6 extends into the resonant cavity 3 and is fixed to one end of the first spring 5. The rotation of the torsion bar 6 drives the first spring 5 to rotate and adjusts the stiffness of the first spring 5, so as to adapt to different systems.

[0033] In addition, in order to limit the position of the torsion bar 6 after twisting, as shown in FIG. Figure 2 As shown, the side wall of the torsion bar 6 at one end located outside is provided with notches at equal intervals to form a first convex tooth 61 , and the side wall of the limit rod 7 at one end located outside is also provided with notches at equal intervals to form a second convex tooth 71 meshing with the first convex tooth 61 .

[0034] It should be noted that a first torsion bar 72 is fixed through the middle of the limit rod 7, one end of the first torsion bar 72 extends to the inner cavity of the combiner body 1, and is connected to the combiner body 1 through the annular groove and the moving block, so that the first torsion bar 72 can drive the limit rod 7 to rotate, and the other end of the first torsion bar 72 is located outside and has an uneven friction pattern on its surface. The friction pattern makes it convenient for the user to rotate the first torsion bar 72 by pinching it.

[0035] like Figure 3 As shown, a socket 721 is provided through the middle of the first torsion bar 72, and a clamping groove 722 is provided on one side of the socket 721 located at the port of the inner cavity of the combiner body 1. A second torsion bar 73 is inserted into the socket 721, and the second torsion bar 73 is longer than the socket 721, and a clamping block 731 inserted into the clamping groove 722 is fixed to the side wall of the contact end of the second torsion bar 73 and the clamping groove 722.

[0036] It should be noted that when the second torsion bar 73 moves into the engaging groove 722 , the engaging block 731 is separated from the engaging groove 722 , and the first torsion bar 72 becomes rotatable from being locked without a limit.

[0037] like Figure 4As shown, both sides of the inner wall of the socket 721 are provided with a slide groove 723, a positioning rod 724 is fixed in the middle of the inner cavity of the slide groove 723, a second spring 725 with one end fixed to the bottom wall of the slide groove 723 is sleeved on the positioning rod 724, and a moving block 726 is fixed to the other end of the second spring 725, and the moving block 726 sleeves the positioning rod 724, and one side is fixed to the side wall of the second torsion bar 73. When the second torsion bar 72 lacks external force to squeeze, the moving block 726 drives the second torsion bar 72 to move upward under the elastic reset of the second spring 725, so that the clamping block 731 is inserted into the clamping groove 722 to lock the first torsion bar 72.

[0038] It should be noted that, due to the meshing of the first protruding teeth 61 and the second protruding teeth 71 , the torsion bar 6 and the limiting rod 7 rotate in the same amount each time, which makes it easier for the user to grasp the degree of torsion of the first spring 5 .

[0039] Working principle: By setting a meshing limit rod 7 next to the frequency resonance rod composed of the first spring 5 and the torsion bar 6, the limit rod 7 can be determined by the insertion and disengagement of its internal clamping block 731 and the clamping groove 722 to determine whether the limit rod 7 can rotate, so that the frequency resonance rod will not move after the adjustment is completed, so as to avoid being unable to adapt to different systems and forming resonance.

[0040] Importantly, it should be noted that the construction and arrangement of the present application shown in a number of different exemplary embodiments are only exemplary. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, directional changes, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in the application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete element may be changed or changed.
