In this embodiment, the outer diameter of the second spring 1905 is 3mm-10mm.
When the direction of the insulating cone 17 is adjusted, the second bullet 1903 is pressed, causing the second bullet 1903 to move away from the second detachable gear 331 and compress the second spring 1905; and when the insulating cone 17 rotates to a target position, the second bullet 1903 is released, so that the second bullet 1903 and the second detachable gear 331 are restored to be meshed, and the second bullet 1903 props against the groove of the second detachable gear 331, so that the insulating cone 17 is fixed.
In this embodiment, the specific structure and connection relationship of other components are just described in embodiment 1. Compared with the embodiment 1, the embodiment saves the time for adjusting the angle of the insulation cone on site, and saves time and labor.
