The outer peripheral wall of the water inlet body 1 at the notch groove is sleeved with a reset unit that cooperates with the limit unit and is used to limit the assembly ring sleeve 2 from sliding too deep and can reset it. The reset unit is a reset spring 3. One end of the reset spring 3 conflicts with the stepped surface in the water inlet body 1, and the other end of the reset spring 3 conflicts with the assembly ring sleeve 2. The inner wall of the assembly ring sleeve 2 at the notch groove is provided with a radially outward protrusion, which is for the reset spring 3 to conflict with, and is slidably fitted with the wall surface of the water inlet body 1 at the notch groove. The convex ring portion 4 conflicts with the stepped surface in the water inlet body 1, and the stepped surface conflicting with the convex ring portion 4 is used In order to limit the sliding depth of the assembly ring sleeve 2 and to limit the position and activity space of the reset spring 3 after assembly, an annular groove for installing the reset spring 3 is provided on the inner wall surface of the assembly ring sleeve 2 located at the reset spring 3. The clamping unit is composed of a plurality of balls 7. A plurality of assembly holes for installing the corresponding balls 7 are provided on the outer peripheral wall of the water inlet pipe fitting located at the notch groove. The inner wall of the assembly hole is arranged in an inclined structure, and the minimum inner diameter of the assembly hole is smaller than the diameter of the ball 7, so that the ball 7 partially extends into the water inlet. When other pipe fittings extend in, they are clamped by cooperating with the assembly ring sleeve 2. Other pipe fittings also need to be opened on the outer peripheral wall. The annular groove is convenient for the partial insertion of the ball 7. The outer peripheral wall of the assembly ring sleeve 2 at the convex ring portion 4 is provided with a plurality of assembly grooves for the corresponding balls 7 to be installed in the assembly hole. A sealing cover can be provided at the assembly groove of the assembly ring sleeve 2, which can not only play a sealing role but also limit the ball 7. The ball 7 can also be assembled in other ways.
