In the tap that this embodiment provided, adapter sleeve 2 establishes the rigid coupling relation through joint and the mode of spline grafting with pipe body 1, and when adapter sleeve 2 and pipe body 1 rigid coupling target in place, it has the external screw thread 23 that exposes in the first end 11 of pipe body 1, and this external screw thread 23 is used for supplying water subassembly 3 spiro union, and welding process has been avoided in the setting of adapter sleeve 2, and it can enough guarantee the aesthetic property of tap outward appearance, can also reduce the material requirement to the accessory simultaneously to be favorable to controlling manufacturing cost. During the installation, adapter sleeve 2 under the circumstances of rotation stopping protruding 21 and rotation stopping slot 13, from the first end 11 of pipe body 1 insert pipe body 1 until elasticity buckle 22 and joint face 141 form the joint can, simple to operate and operating cost hang down.

The above description of the specification and examples is intended to illustrate the scope of the invention, but should not be construed as limiting the scope of the invention.
