clamping assembly of outer sleeve 2 with basin 200: the fastener 4 is slidably assembled on the first limit chute 22 of the outer sleeve 2, specifically, the fastener 4 and the first limit chute 22 can be slidably assembled together through the limit sliding block 41, the fastener 4 is located at the lower part of the first limit chute 22, specifically, the fastener 4 is located on the first limit chute 22 on the outer wall of the extension portion 24, so that the extension portion 24 and the fastener 4 together pass through the assembly hole 201 of the counter basin 200 from top to bottom, the fastening screw 5 passes through the clamping piece 21 and is in threaded connection with the fastener 4, and specifically, when the fixing structure 100 is provided with two fastening screws 5, both fastening screws 5 need to pass through the clamping piece 21 and be in threaded connection with the fastener 4; passing the lower portion of the outer sleeve 2 (i.e., the extension 24) and the fastener 4 together from above down through the mounting hole 201 in the tub 200, allowing the fastener 4 to enter below the tub 200; the outer sleeve 2 is continuously inserted into the assembly hole 201 of the counter basin 200 downwards until the clamping piece 21 at the upper end of the outer sleeve 2 is supported on the upper surface of the counter basin 200, and at the moment, only a small gap is reserved between the outer sleeve 2 and the assembly hole 201 of the counter basin 200, so that the outer sleeve 2 can be well limited, and the outer sleeve 2 cannot horizontally move; rotating the fastening screw 5 to enable the fastening piece 4 to slide upwards along the first limit chute 22 until the clamping piece 21 and the fastening piece 4 clamp the counter basin 200, and stopping rotating the fastening screw 5; similarly, when the fixing structure 100 is provided with two fastening screws 5, both the fastening screws 5 need to be rotated to ensure that the fastening piece 4 can slide upwards along the first limiting chute 22 to achieve clamping; because the clamping piece 21 is matched with the fastening piece 4 to clamp the counter basin 200, the outer sleeve 2 can be limited in the assembly hole 201 of the counter basin 200, and the fastening piece 4 can be limited in the first limiting chute 22, no matter how the tap body 1 is rotated in the use process, the outer sleeve 2 and the counter basin 200 are not easy to loosen;

threaded assembly of the inner sleeve 3 with the tap body 1: the connecting section of the tap body 1 and the inner sleeve 3 is connected together through threads;

assembly of the outer sleeve 2 with the inner sleeve 3: aligning the lower end of the second limit chute 32 of the inner sleeve 3 with the limit protrusion 23 in the outer sleeve 2; the inner sleeve 3 is inserted into the outer sleeve 2 downwards, the connecting section 31 of the inner sleeve 3 is supported at the upper end of the outer sleeve 2, and in particular, the upper end surface of the outer sleeve 2 is flush with the upper surface of the clamping piece 11, so that the connecting section 31 is better supported;

wherein, the clamping assembly of the outer sleeve 2 and the counter basin 200 and the threaded assembly of the inner sleeve 3 and the tap body 1 are not sequential; namely, during the concrete assembly, the outer sleeve 2 and the basin 200 are clamped and assembled together, and then the inner sleeve 3 and the screw thread of the tap body 1 are assembled together; it is also possible to assemble the inner sleeve 3 with the threads of the tap body 1 first and then to clamp the outer sleeve 2 with the basin 200.

In a preferred embodiment of the present utility model, in order to prevent loosening between the tap body 1 and the inner sleeve 3, the threaded assembly of the inner sleeve 3 with the tap body 1 further comprises:

after the tap body 1 and the connecting section of the inner sleeve 3 are connected together through threads, the propping piece 62 of the propping piece 6 is inserted into the extending opening 312, the propping convex part 611 of the locking piece 61 on the propping piece 6 faces the groove wall of the second limiting chute 32, and the locking piece 61 is locked on the groove wall of the second limiting chute 32 through the locking piece 7, so that the free end of the propping piece 62 penetrates through the extending opening 312 and is propped against the inner wall of the lower end of the tap body 1, and the tap body 1 and the inner sleeve 3 can be reliably combined together, and the loose condition can not occur in the using process.

While specific embodiments of the utility model have been described above, it will be appreciated by those skilled in the art that the specific embodiments described are illustrative only and not intended to limit the scope of the utility model, and that equivalent modifications and variations of the utility model in light of the spirit of the utility model will be covered by the claims of the present utility model.
