DESCRIPTION OF THE EMBODIMENT AND IMPLEMENTATION OF THE METHOD

[0032] In the embodiment shown in FIGS. 1 and 2, the diameter of the top of the T-shaped flange 1 is larger than the diameter of the faucet fixing hole of the sink. The two sides of the T-shaped flange 1 are provided with guide grooves 11 and screw holes 16 respectively. The first step 12, the second step 13 can be installed in the guide grooves 11 on both sides of the T-shaped flange 1 respectively to install tightening components, the lower end of the T-shaped flange 1 is provided with a first step 12 and a second step 13. The first step 12 is lower than the second step 13, and the tightening component can be rotated and unfolded from the first step 12 of the T-shaped flange 1, or rotated and collapsed into the T-shaped flange 1.

[0033] In the embodiment shown in FIGS. 3 to 5, the T-shaped flange 1 is equipped with a tightening screw 23 and a tightening part, and the tightening part is in the T-shaped flange 1 in a closed static state, which can be rotated out of the first step 12 of the T-shaped flange 1 from the folded state, and when the tightening screw 23 rotates, the tightening member is driven to rotate synchronously with the tightening screw 23 as the axis.

[0034] The tightening component is provided with an outer shoulder 21 and a threaded connecting portion 22. The outer shoulder 21 is larger than the guide groove 11, and the threaded connecting portion 22 is smaller than the outer shoulder 21. It can be fitted into the guide groove to fit, and tighten the screw 23. Under the occlusal pull, the threaded connection part 22 can move in the guide groove 11, and the outer shoulder 21 can only move against the outer wall of the T-shaped flange 1.

[0035] The T-shaped flange 1 is provided with two screw holes 16 symmetrical to each other. A tightening screw 23 can be installed in the screw hole 16, and the tightening screw 23 is installed into the screw hole 16 for damping and clamping, by static friction. The tightening screw 23 can only be rotated when the tightening screw 23 is rotated under the action of the external force of the screwdriver. When the tightening screw 23 is not rotated, the tightening screw 23 is statically clamped in the screw hole 16. Alternatively, you can add viscous damping glue to the screw hole 16, so that the tightening screw 23 can be installed into the screw hole 16 to be stationary, and the rotation force of the tightening screw 23 is greater than the viscous force when the tightening screw 23 is rotated under the action of the external force of the screwdriver, which makes the tightening screw 23 to rotate.

[0036] The advantage of installing the tightening screw 23 into the screw hole 16 as a damping card is that the tightening screw 23 can be stationary in the screw hole 16 without rotating when the tightening screw 23 is not rotated by an external force.

[0037] The lower end of the tightening screw 23 is connected with the threaded hole of the threaded connecting portion 22 of the tightening component, and the tightening screw 23 is connected with the threaded hole of the threaded connecting portion 22 for damping fit and clamping, (i.e., static friction fits clamping tightening, when the tightening screw moves relative to the thread hole and overcomes the static friction force, the threads of the threaded connection part bite into the tightening screw thread movement), the tightening screw 23 can drive the tightening part to tighten the screw when the tightening screw 23 rotates in the synchronous rotation of the shaft. In one embodiment, it also includes dripping viscous damping glue into the threaded holes of the threaded connecting portion 22, so that the threaded connecting portion 22 is installed on the lower end of the tightening screw 23 to be statically connected, and the tightening screw is rotated under the action of the external force of the screwdriver. When the rotation force of 23 is greater than the viscous force, the threads of the threaded connection portion 22 bite into the threads of the tightening screw 23 to move relative to each other.

[0038] The advantage of the tightening screw 23 and the threaded connecting portion 22 threaded hole is damping fit and clamping, so that the tightening screw 23 and the tightening part can be statically connected as a whole when not rotated by external force, and no mutual rotation occurs. The tightening part can be installed in the T-shaped flange 1 to stand still. When the tightening screw 23 rotates, the tightening part is controlled to rotate synchronously with the tightening screw 23 as the axis, and the tightening part is caused by the second step 13 when the side stops rotating, the synchronous motion is transformed into the mutual biting motion of the screw teeth, which realizes that the tightening part is installed in the T-flange 1 to stand still, and the tightening screw 23 is turned to unfold, and then tightens upwards.

[0039] In the embodiment shown in FIGS. 4 and 5, the first step 12 and the second step 13 are provided on both sides of the T-shaped flange 1. The advantage is that the tightening part is retracted inside the T-shaped flange 1. In the static state, the tightening screw 23 rotates in the positive direction to drive the tightening part to rotate out of the first step 12 from the inside of the T-shaped flange 1 with the tightening screw 23 as the axis, until the tightening part is unfolded. When the threaded connection 22 touches the side of the second step 13, the tightening part stops rotating, and the tightening screw 23 continues to rotate to overcome the damping of the tightening screw 23 and the threaded hole. At this time, the threaded connection 22 is tightening the screw 23. The thread starts to bite and move upwards, the threaded connection portion 23 enters the guide groove, and the outer shoulder 21 of the tightening component fits the outer wall of the T-flange and tightens upwardly.

[0040] The connecting portion at the top of the T-shaped flange 1 is provided with a connecting concave latching position 14, which can be matched with the connecting convex latching position 32 of the faucet connecting part 3, to connect the faucet connecting part 3 with the T-shaped flange 1.
