In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0027] Example 1

[0028] like Figure 1-4As shown, the utility model provides a technical solution: a portable signal amplifier, comprising: a portable mechanism 1, an auxiliary mechanism 2 is arranged inside the portable mechanism 1, the portable mechanism 1 comprises a rectangular box 11, a device body 117 is arranged inside the rectangular box 11, a back plate 12 is arranged at one end of the device body 117, a limit rod 13 is arranged inside the back plate 12, a fixing block 14 is arranged at one end of the limit rod 13, a knob 15 is arranged at one end of the fixing block 14, a check rod 18 is arranged on one side of the knob 15, and a protrusion 111 is arranged on the inner side of one end of the check rod 18 An outer ring 113 is provided at one end of the protrusion 111, a rectangular box 11 is provided at the bottom of the outer ring 113, a guide rail 16 is provided inside the rectangular box 11, a slider 17 is provided on the inner surface of the guide rail 16, a limit rod 13 is provided at one end of the slider 17, a side plate 110 is provided on one side of the knob 15, a spring 19 is provided on one side of the side plate 110, a check rod 18 is provided at one end of the spring 19, a battery 114 and a gain controller 115 are respectively provided inside the rectangular box 11, and the inside of the rectangular box 11 is fixedly connected to the side of the heat exhaust fan 116.

[0029] In this embodiment, when the modified device is in use, the signal amplifier is fitted along the path of the rectangular box 11. At this time, the back plate 12 is pressed against one end of the device body 117. Then, the knob 15 is rotated so that the fixing block 14 contacts the bottom point on the knob 15. The fixing block 14 is subjected to the pressure of rotation, so that the limiting rod 13 enters the back plate 12 to limit the back plate 12. In this way, the back plate 12 can be fixed to one end of the device body 117 and its movement in the rectangular box 11 is limited. The entry of the limiting rod 13 can prevent the back plate 12 from sliding or shaking, ensuring that the position of the device body 117 is stable and fixed during the carrying process. In order to prevent the knob 15 from rotating at will, a protrusion 111 is installed around the knob 15. When the knob 15 is rotated, the check rod 18 will continuously contact the protrusion 111. When it is rotated to the required position, the check rod 18 will automatically engage with the protrusion 111, thereby preventing the knob 15 from rotating at will.

[0030] Secondly, by connecting the gain controller 115 in the rectangular box 11 with the device body 117, the gain level of the amplifier can be automatically adjusted according to the strength and quality of the signal to ensure stable signal transmission. The battery 114 and the heat exhaust fan 116 installed in the rectangular box 11, the battery 114 can provide backup power support for the device. When the power supply of the power grid is unstable or fails, the battery 114 can provide a continuous power supply to ensure that the normal operation of the device is not affected. The installation of the heat exhaust fan 116 can effectively dissipate the heat inside the rectangular box 11 to prevent the device from overheating and damage.

[0031] Example 2

[0032] like Figure 1-4As shown, the auxiliary mechanism 2 includes a handle 21, the inner wall of the handle 21 is in sliding contact with one side of a fixed column 24, the other side of the fixed column 24 is fixedly connected to one side of a magnetic block 22, the other side of the magnetic block 1 is in contact with one side of a magnetic block 23, the other side of the magnetic block 23 is fixedly connected to the inner wall of the handle 21, one end of the handle 21 is slidably connected to the interior of the rectangular box 11, and the inner wall of the rectangular box 11 is fixedly connected to one end of the fixed column 24.

[0033] In this embodiment, the handle 21 is pulled out from the rectangular box 11, which makes it more convenient to carry without the need for additional tools or brackets, thereby saving space and strength for carrying. When the handle 21 needs to be pushed back into the rectangular box 11, a magnetic block 23 is installed on the inner wall of the handle 21. Therefore, during this process, the magnetic block 23 will gradually fit with the magnetic block 1 22 on the fixed column 24. This magnetic effect can help ensure that the handle 21 is firmly fixed in the rectangular box 11, thereby preventing the handle 21 from accidentally moving or swinging during transportation or carrying, thereby improving the safety and stability of the device.

[0034] Working principle:

[0035] like Figure 1-4 As shown, the signal amplifier is fitted along the path of the rectangular box 11. At this time, the back panel 12 is pressed against one end of the device body 117. Then, the knob 15 is turned to make the fixing block 14 contact the bottom point on the knob 15. The fixing block 14 is subjected to the pressure of rotation, so that the limit rod 13 enters the back panel 12 to limit the back panel 12. In this way, the back panel 12 can be fixed to one end of the device body 117 and its movement in the rectangular box 11 can be limited. A protrusion 111 is installed around the knob 15. When the knob 15 is rotated, the check rod 18 will continuously contact the protrusion 111. When it is rotated to the required position, the check rod 18 will automatically engage with the protrusion 111. Secondly, by connecting the gain controller 115 in the rectangular box 11 with the device body 117, the gain level of the amplifier can be automatically adjusted according to the strength and quality of the signal to ensure stable signal transmission.
