Dust buildup not only affects the signal but also heat dissipation. Furthermore, the amplifier requires antenna adjustment to improve its performance, but this adjustment results in poor antenna stability. Existing amplifiers lack components to secure the antenna, further compromising stability.

[0004] Therefore, we propose a highly stable mobile phone signal amplifier to solve the problems mentioned above. Utility Model Content

[0031] In this embodiment: During use, the operator can install the mounting plate 1 in a suitable position using the mounting block 2, and then place the amplifier body 5 on the pad block 4. The fixed frame 3 can limit the position of the amplifier body 5. After placement, the knob 87 can be rotated. When the knob 87 is rotated, it will drive the front threaded rod 84 to rotate. At this time, the belt 86 will drive the front and rear threaded rods 84 to rotate synchronously. When the threaded rod 84 rotates, it will drive the adjacent threaded sleeves 83 to move relative to each other. When the threaded sleeves 83 move relative to each other, they will drive the dustproof frames 81 on both sides to move relative to each other through the adjacent connecting rod 82, thereby achieving dust protection for the amplifier body 5. When the dustproof frames 81 move relative to each other until they fit together, the knob 87 can be stopped.

[0032] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 , Figure 5-6 and Figure 8 The positioning component 7 includes a disc 71 fixedly sleeved on the outside of the antenna 6 and a positioning rod 72 located on the right side of the disc 71.

[0036] In this embodiment, the angle of the antenna 6 can be adjusted as needed. When adjusting, pull the n-shaped handle 761 to the right. When the n-shaped handle 761 moves to the right, it will drive the pull plate 76 to move to the right. When the pull plate 76 moves to the right, it will drive the pull rod 75 to move to the right and squeeze the spring 751. At the same time, it will also drive the movable plate 73 to move to the right. When the movable plate 73 moves to the right, it will drive the positioning rod 72 to move to the right.

[0037] Working principle: During use, the operator can install the mounting plate 1 in a suitable position using the mounting block 2, and then place the amplifier body 5 on the pad block 4. The fixing frame 3 serves to limit the position of the amplifier body 5. After placement, the knob 87 can be turned. When the knob 87 is turned, it will drive the front threaded rod 84 to rotate. At this time, the belt 86 will drive the front and rear threaded rods 84 to rotate synchronously. When the threaded rod 84 rotates, it will drive the adjacent threaded sleeves 83 to move relative to each other. When the threaded sleeves 83 move relative to each other, they will drive the dustproof frames 81 on both sides to move relative to each other through the adjacent connecting rods 82, thus achieving dust protection for the amplifier body 5. When the dustproof frames 81 move relative to each other until they fit together, the knob 87 can be stopped. In addition, when placing... After the main body 5 is placed, the angle of the antenna 6 can be adjusted as needed. When adjusting, pull the n-shaped handle 761 to the right. When the n-shaped handle 761 moves to the right, it will drive the pull plate 76 to move to the right. When the pull plate 76 moves to the right, it will drive the pull rod 75 to move to the right and squeeze the spring 751. At the same time, it will also drive the movable plate 73 to move to the right. When the movable plate 73 moves to the right, it will drive the positioning rod 72 to move to the right. At this time, the locking of the disc 71 can be released. Then, the angle of the antenna 6 can be adjusted. When the signal is good, stop pulling the n-shaped handle 761. At this time, the positioning rod 72 will return to its original position under the action of the spring 751, and then continue to be inserted into the inner cavity of one of the positioning slots 711 to fix the position of the antenna 6.
