The base 12 is in a disc shape and abuts against the wall surface. The diameter of the base 12 is larger than the diameter of the sleeved section 11. The base 12 functions to limit the sleeved section 11 and can prevent the sleeved section 11 from shaking relative to the water outlet pipe 6 and the like.

[0030] Two protrusions 111 are provided on the outer wall of the sleeved section 11 of the base 1. The protrusions 111 are arranged at an interval of 180° along the circumferential direction of the sleeved section 11. A fitting 112 is provided through one of the protrusions 111. In this embodiment, the fitting 112 is a threaded hole integrally formed or machined on the protrusion 111. The connection structure further includes a fastener 3. In this embodiment, the fastener 3 is a screw, and the screw is threadedly connected to the threaded hole. After the base 1 is sleeved on the water outlet pipe 6, the base 1 axially moves along the water outlet pipe 6 until the base 12 abuts against the wall surface. The positions of the two protrusions 111 are adjusted so that the protrusion 111 provided with the fitting 112 is vertically upward and the other protrusion 111 is vertically downward. The fastener 3 is operably moved on the fitting 112 to press and fix on the water outlet pipe 6 to achieve the fixed connection between the base 1 and the water outlet pipe 6. The fastener 3 is tightened so that the end of the fastener 3 is fixedly abutted against the outer wall of the water outlet pipe 6. At this time, the base 1 is fixedly arranged on the water outlet pipe 6.
