[0030] The specific working process of this utility model:

[0031] Before clamping the water inlet pipe, first screw the elbow pipe into the threaded hole of the water inlet pipe, and control the height and pre-installation angle. Place the water inlet pipe with the elbow pipe horizontally on the cushion block 13. The design thickness of the cushion block 13 makes the water inlet pipe installation hole and the positioning pin 16 and the positioning pin 2 17 on the support plate 2 align respectively. Push the water inlet pipe to be installed on the support plate 2 so that the positioning pin 16 and the positioning pin 2 17 pass through the water inlet pipe installation hole respectively, and then install the pressing plate 5 on the pull rod 4. At this time, the support plate 2 and the pressing plate 5 clamp the water inlet pipe, and then tighten the locking nut 1 3 at one end of the pull rod 4, so that the pressing plate 5, the water inlet pipe and the support plate 2 are tightly connected, and the water pipe is pressed and fixed.

[0032] At this time, continue to turn the elbow pipe by hand until it is close to the adjusting sleeve 8, and adjust it until the positioning surface of the elbow pipe is basically parallel to one end of the adjusting sleeve 8. At this time, rotate the adjusting sleeve 8 until the elbow pipe contacts the adjusting sleeve 8, and then rely on the locking nut 3 10 to fix the adjusting sleeve 8. That is, the angle size of the elbow pipe relative to the water inlet pipe is determined. Even if the relative positions of the two mounting holes at one place on the water inlet pipe and the elbow pipe mounting holes at another place are inconsistent, or the deviation is large, the product angle design requirements can be met through the adjusting sleeve.

[0033] After the elbow pipe is tightened, loosen the locking nut 3, move the pull rod 4 backward, pull out the pressure plate 4, and the water inlet pipe can be quickly removed.

[0034] In order to simplify the design, the water inlet pipe and elbow pipe are no longer marked in the attached drawings. Please note this.
