This is an existing well-known technology and will not be elaborated here.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the female head 11 has a cavity, and a resistance structure for limiting the male head 12 is provided in the cavity of the female head 11, and the resistance structure includes a guide body 20 and a covering member 21, and the covering member 21 is detachably mounted on the inner wall of the female head 11, and the guide body 20 is fixedly connected to the female head 11, and the guide body 20 can guide the male head 12 to be inserted into the belly of the covering member 21, and the wall surface of the covering member 21 forms a plurality of petal-like structures, and the male head 12 can push the covering member 21 to expand and deform, and the male head 12 forms a cylindrical structure, and the female head 11 is tubular, and the inner diameter of the female head 11 is larger than the diameter of the male head 12, and the covering member 21 forms a funnel-shaped structure, and the smaller port of the covering member 21 is fixedly connected to the upper end surface of the female head 11, and the guide body 20 is relatively large. The large port faces the male head 12. In the present solution, a covering member 21 is provided in the cavity of the female head 11, which cooperates with the guide body 20 on the top surface of the female head 11. When the male head 12 is plugged into the female head 11, the male head 12 is guided into the cavity of the covering member 21 through the cavity of the guide body 20. Due to the petal structure of the covering member 21, the covering member 21 has a certain deformation and expansion ability. When the male head 12 is inserted into the cavity of the female head 11, the covering member 21 can better cover the male head 12, with a higher degree of fit and a larger contact surface.
