The antenna emits radio waves through the operation of the transmitter. When switching is required, the operation of the servo motor 3 can drive the first rotating shaft 4 and the second rotating shaft 6 to rotate, thereby driving the power board 7 to rotate, so that the power board 7 is switched to insert different power socket components 8 to achieve the switching function;

[0044] The power board 7 is an L-shaped structure;

[0045] The shaft coupling component 5 includes a first circular plate 501, a second circular plate 502, a round pin 503, a limit spring 504 and a circular groove 505. The second circular plate 502 is rotatably connected to the first circular plate 501. The second circular plate 502 is provided with an inner cavity, and the round pin 503 is slidably connected to the inner cavity of the second circular plate 502.

The limit spring 504 is in a compressed state. Through the technical solution, the round head pin 503 is pressed against the circular groove 505 through the elastic action of the limit spring 504, so that the first circular plate 501 and the second circular plate 502 are relatively fixed, so that the second rotating shaft 6 can be driven to rotate when the first rotating shaft 4 rotates;

[0049] The auxiliary fixing component 9 includes a fixed cylinder 901, a movable piston 902, a pressure rod 903, a round head 904 and a connecting pipe 905.

[0050] The first rotating shaft 4 is fixedly connected with a pressure plate 11. Through the technical solution, after the servo motor 3 drives the first rotating shaft 4 and the second rotating shaft 6 to rotate, the power board 7 is rotated and inserted into the power socket component 8. After the power board 7 is inserted into the power socket component 8, the position of the power board 7 is fixed due to the limiting effect of the rubber support block 803, and then the second rotating shaft 6 is fixed. Since the second rotating shaft 6 is fixed, the first rotating shaft 4 continues to rotate. Due to the existence of the coupling component 5, the torque of the rotation of the first rotating shaft 4 is transmitted to the second circular plate 502, so that the round head pin 503 is squeezed and retracted into the inner cavity of the second circular plate 502, so that the second circular plate 502 can continue to rotate, and the first rotating shaft 4 It can continue to rotate, thereby driving the pressure plate 11 to rotate, so that the pressure plate 11 rotates and presses down the round head 904, thereby driving the pressure rod 903 to press down, and the downward pressure of the pressure rod 903 drives the movable piston 902 to press down, so that the gas in the inner cavity of the fixed cylinder 901 is pressed into the inner cavity of the fixed airbag 804 through the connecting pipe 905, so that the fixed airbag 804 expands, and then the expanded fixed airbag 804 makes the power connection spring 802 open, so that the fixed airbag 804 further clamps the power connection plate 7, thereby further improving the fixing effect, achieving a better power connection effect, and avoiding the problem of unstable connection caused by looseness.
