Those skilled in the art can also connect the LED1 indicator light group and the LED2 indicator light group by wireless connection.

[0030] In this embodiment, the LED1 indicator light and the LED2 indicator light both emit red light and have a warning function, and are both provided with a diffuser mask on their surfaces for uniform and soft light emission. The surface of the LED2 indicator light group (102) is arc-shaped and smooth to prevent it from being scratched and falling off. The surface of the LED1 indicator light group (109) is arc-shaped and smooth to reduce wind resistance and prevent it from being scratched and falling off.

[0031] like Figure 4As shown, the circuit principle of the present invention is as follows: the power module is a DC power supply that can be powered by dry batteries and is easy to replace. It is used to provide working power for the device and is electrically connected to the touch chip 1, touch chip 2, microprocessor, LED1 indicator light, and LED2 indicator light through a power switch.
