In this embodiment, the water stop plug 400 includes a sleeve 410 and a core 420, the sleeve 410 is a cylindrical structure with two open ends, and the inner cavity of the sleeve 410 is tapered, that is, the bore diameter of the inner cavity gradually increases or decreases from one end to the other end. The core 420 has a tapered structure, that is, the outer diameter of the core 420 gradually increases or decreases from one end to the other end, so that the smaller end of the outer wall of the core 420 enters from the larger end of the inner cavity of the sleeve 410, and during the gradual entry of the core 420, the outer wall of the sleeve 410 is pressed outwards, so that the sleeve 410 expands or expands outwards to achieve the purpose of sealing. The core 420 is connected to the second screw 23 of the inner rod assembly 2 of the stop-cock installation tool 100.

The above is only the optional embodiment of the present invention, and not therefore the limit to the patent scope of the present invention, all the concepts of the present invention utilize the equivalent structure transformation of the content of the specification and the attached drawings, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
