By designing the ball bearing 85, the movement of the sliding rod 84 can be guided. A fixed rod 86 is slidably sleeved inside the sliding rod 84. The fixed rod 86 is fixedly connected to the connecting seat 5. A first spring 87 is provided on the outside of the fixed rod 86.

By designing the first spring 87, the force of the first spring 87 can act on the sliding rod 84. By designing the connecting mechanism 8, it is convenient to disassemble the main body 6.

[0024] Please see Figure 1 , Figure 2 , Figure 4The rotating mechanism 9 includes a protrusion 91. The protrusion 91 is fixedly connected inside the fixed seat 3. A ball 92 contacts the outside of the protrusion 91. The ball 92 is movably connected to the rotating seat 4. A slider 93 is movably sleeved on the outside of the ball 92. The slider 93 is slidably connected to the rotating seat 4. A guide rod 94 is fixedly connected on the outside of the slider 93. The guide rod 94 is slidably connected to the rotating seat 4.

[0025] The specific implementation process of this utility model is as follows: In use, the body 6 enhances the wireless communication signal. The antenna 10 is rotatably mounted on the body 6 and can rotate freely. When the body 6 is rotated, the body 6 drives the connecting seat 5 and the rotating seat 4 to rotate. The rotating seat 4 rotates inside the fixed seat 3, and the rotating seat 4 drives the ball 92 to rotate. The ball 92 rotates and rolls along the protrusion 91. The ball 92 is squeezed into the rotating seat 4 and rolls. The ball 92 drives the slider 93 and the guide rod 94 to move. The slider 93 squeezes the second spring 95, allowing the ball 92 to roll through the protrusion 91. Then, under the elastic action of the second spring 95, a reverse thrust is given to the slider 93, which pushes the ball 92 back to its original position. The ball 92 rolls into the groove between two adjacent protrusions 91. At this time, the ball 92 and the rotating seat 4 can be limited, thus completing the rotation adjustment of the rotating seat 4. This facilitates the flexible rotation adjustment of the body 6. Combined with the rotation of the antenna 10, the direction of use of the antenna 10 can be flexibly adjusted, which can improve the signal enhancement effect.

[0026] When it is necessary to disassemble the main body 6, simply pull the main body 6 upwards. The main body 6 will move the connecting block 7, which in turn will move the connecting column 81. The connecting column 81 will slide along the arc-shaped block 83. The arc surface of the arc groove 82 inside the connecting column 81 will press and push the arc block 83. The arc block 83 will move the sliding rod 84, which will move the ball bearing 85 along the connecting seat 5. The sliding rod 84 will slide along the fixed rod 86 and press the first spring 87. Finally, the arc block 83 can be separated from the arc groove 82, and the connecting column 81 can be pulled out from the connecting seat 5. This will facilitate the disassembly of the main body 6 after its installation and use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
