When the female component 1 is threadedly connected with the male component 2, the female component 1 moves toward the inside of the male component 2, driving the tamping rod 6 to move downward. When the tamping rod 6 moves downward, it contacts the top of the moving disk 8, and after continuing to move, the moving disk 8 is pushed downward. The moving disk 8 slides downward inside the base 7. When the moving disk 8 moves downward, it drives the moving rod 12 to move downward. The downward movement of the moving rod 12 drives the left end of the swing rod 11 to move downward, and the left end of the swing rod 11 moves downward. Move its right end upward, driving the bottom end of the vertical rod 13 to tilt outward, and the bottom end of the vertical rod 13 tilts outward to make its top move inward, pushing the cross bar 14 to the left close to the female component 1. When the female component 1 completely enters the male component 2, the limit ring 4 moves to the left side of the cross bar 14, and the cross bar 14 moves to the left to fit the surface of the limit ring 4 and fix it. At the same time, by setting the guide column 5 and the receiving column 15, the docking of the female component 1 and the male component 2 is facilitated, and they can be directly connected without the need for holes, so as to achieve effective fixation of the male head after the docking of the male and female heads is completed, to avoid loosening of the male head during use, resulting in poor contact and damage to the electrical appliance, and to facilitate the use of the user.
