In addition, during the movement of the connecting male end 7, the slider 24 also slides in the slide groove, and during the sliding process of the slider 24 in the slide groove, the friction force is small, and no large rotational force will be formed on the slider 24, and even if there is a certain friction force, the abutment block 25 will gradually approach the gear ring 14, and the force on the gear ring 14 will gradually increase;

[0052] Through the cooperation between the arc plate 22 and the annular baffle 19, the cooperation between the square block 21 and the groove 20, and the cooperation between the triangular block on the abutment block 25 and the toothed ring 14, an effective limit can be formed for the connection between the male end 7 and the female end 6 to prevent the abnormal separation of the female end 6 and the male end 7; in addition, the slider 24 can also play an auxiliary movement effect. The whole structure has a high degree of coordination, a simple structure, and is easy to use. It effectively improves the connection stability between the female end 6 and the male end 7. When the female end 6 needs to be separated from the male end 7, insert the screwdriver into the through hole again, rotate the screwdriver in the opposite direction, and then rotate the slider 24 in the opposite direction together.
