[0021] Specifically, a multi-band antenna 202 is disposed on the top of the signal device 201 .

[0022] In this embodiment, by setting up a multi-band antenna 202, the multi-band antenna 202 can cover multiple communication frequency bands, thereby improving signal transmission capability and increasing data transmission rate, which helps to improve the performance of the mobile phone body 1. It can also reduce the number of antennas, save the internal space of the mobile phone body 1, and is conducive to realizing a lightweight design of the mobile phone body 1.

[0023] Specifically, a signal amplifier 203 is fixedly disposed on the top of the multi-band antenna 202 .

[0024] In this embodiment, by setting up the signal amplifier 203, during the use of the signal device 201, the signal amplifier 203 can increase the signal strength received by the multi-band antenna 202, increase the communication capability of the system, improve the signal transmission distance, and thus improve the stability and reliability of signal transmission.

[0025] Specifically, a pop-up component 204 is fixedly disposed at the bottom of the signal device 201 .

[0026] In this embodiment, by setting a pop-up component 204, after the restriction of the fixing device 206 on the signal device 201 is released, the pop-up component 204 automatically pops up the signal device 201, so that the signal device 201 extends to the side away from the human body, thereby enhancing the signal and reducing the battery radiation of the mobile phone body 1.

[0027] Specifically, the connection relationship between the positioning rod 306 and the movable plate 305 is a sliding connection.

[0028] In this embodiment, by providing the moving plate 305 and the positioning rod 306 , when the moving plate 305 moves, the positioning rod 306 is provided so that the moving direction of the moving plate 305 always remains horizontal.

[0029] Specifically, a clamping hole 309 adapted to the clamping column 304 is provided in the middle of the sliding block 302 , and the connection relationship between the clamping hole 309 and the clamping column 304 is a clamping connection.

[0030] In this embodiment, by setting a slider 302 and a clamping hole 309, during the movement of the slider 302, one side of the slider 302 squeezes the clamping column 304, so that the reset spring 307 is compressed. When the clamping column 304 is aligned with the clamping hole 309, under the elastic action of the reset spring 307, the clamping column 304 is clamped with the slider 302 to limit the slider 302.

[0031] When in use, the knob 207 is turned to release the restriction on the signal device 201, and the pop-up component 204 will automatically pop up the signal device 201, so that the signal device 201 extends to the side away from the human body, reducing the battery radiation of the mobile phone and the harm of electromagnetic radiation. The operation of the multi-band antenna 202 and the signal amplifier 203 can increase the signal of the mobile phone body 1 and improve the performance of the mobile phone body 1.

[0032] After use, the signal device 201 is inserted into the groove of the mobile phone body 1. The connection between the fixing device 206 and the limiting hole 205 keeps the signal device 201 stable.

The clamping column 304 is pressed with an ejector pin, and the movable plate 305 moves in the installation cavity 308 to the side away from the through hole 311. The setting of the positioning rod 306 keeps the movement of the movable plate 305 in a horizontal state. At the same time, the reset spring 307 is squeezed, and when the clamping column 304 completely enters the through hole 311, the slider 302 continues to slide up. When the clamping hole 309 on the slider 302 is aligned with the clamping column 304, the movable plate 305 drives the clamping column 304 to move out of the through hole 311 under the elastic force of the reset spring 307, and is clamped into the clamping hole 309, thereby limiting the slider 302 and achieving the purpose of fixing the protective shell 301. At this time, the protective shell 301 can protect the knob 207 and improve the stability of the signal device 201.

[0033] In summary, the multi-band mobile phone antenna, by providing a protective shell 301, when the knob 207 is not in use, the protective shell 301 outside the knob 207 can effectively prevent the knob 207 from accidentally touching the knob 207 due to external force, causing the knob 207 to rotate, so as to improve the stability of the signal device 201. At the same time, the protective shell 301 can also provide protection, reduce the physical impact on the knob 207, and reduce the dust, dirt or other contaminants from entering the knob 207, thereby ensuring the normal operation and stable performance of the knob 207, which is conducive to extending the service life of the knob 207. By providing a slider 302, a clamping column 304, a moving plate 305, a reset spring 307, a clamping hole 309 and a through hole 311 The slider 302 moves upward in the slide groove 303 until the top of the slider 302 is close to the upper clamping column 304, and the clamping column 304 is pressed by the ejector pin, and the clamping column 304 moves in the through hole 311. The movable plate 305 moves horizontally with the movement of the movable plate 305 under the restriction of the positioning rod 306, and the reset spring 307 is squeezed at the same time. When the clamping column 304 completely enters the through hole 311, the slider 302 continues to slide. When the clamping column 304 is aligned with the clamping hole 309 on the slider 302, the elastic force of the reset spring 307 makes the clamping column 304 clamped into the clamping hole 309, limiting the slider 302, fixing the protective shell 301, and improving the stability of the protective shell 301.
