The nozzle adjustment member, as recited in claim 2, further comprising a seat, at least one water inlet arranged at least one side of said seat for connecting with a water source, a pivot connecting said hollow pipe with said seat to enable said hollow pipe to rotate at reversibly rotational manner, a fine adjustment knob operatively coupled with said pivot for controlling outlet water flow extending outward from said pivot, and a control button operatively coupled at said hollow pipe for angle adjustment of forward and backward movement of said hollow pipe via said pivot. 5. The nozzle adjustment member, as recited in claim 1, wherein each of said adjustment pieces further comprises a Pivot bushing formed at said end of said adjustment piece to form said pivot hole within said pivot bushing, wherein said pivot bushing is pivoted at said pivot support, wherein at least one pin is arranged at a bottom of said adjustment piece, wherein said pivot bushing and said pin have the same height to lean against said top stage. 6. The nozzle adjustment member, as recited in claim 4, wherein each of said adjustment pieces further comprises a Pivot bushing formed at said end of said adjustment piece to form said pivot hole within said pivot bushing, wherein said pivot bushing is pivoted at said pivot support, wherein at least one pin is arranged at a bottom of said adjustment piece, wherein said Divot bushing and said pin have the same height to lean against said too stage. 7. The nozzle adjustment member, as recited in claim 1, wherein said pivot support is arranged at each diagonal corner of said two rows of said plurality of holes, around said farthest hole. 8. The nozzle adjustment member, as recited in claim 6, wherein said pivot support is arranged at each diagonal corner of said two rows of said plurality of holes, around said farthest hole. 9. The nozzle adjustment member, as recited in claim 1, wherein said pivot support is arranged at an outer end of the farthest hole. 10. The nozzle adjustment member, as recited in claim 1, wherein bottoms of said plurality of nozzle tubes are connected into one piece or connected into two independent nozzle sets. 11. The nozzle adjustment member, as recited in claim 6, wherein bottoms of said plurality of nozzle tubes are connected into one piece or connected into two independent nozzle sets. 12. The nozzle adjustment member, as recited in claim 1, wherein at least two receiving spaces for receiving said control part are arranged at said nozzle cover. 13. The nozzle adjustment member, as recited in claim 4, wherein two receiving spaces for receiving said two control part are arranged at two opposite sides of said nozzle cover. 14. The nozzle adjustment member, as recited in claim 1, wherein each of said adjustment pieces is integrated with each of said control parts. 15. The nozzle adjustment member, as recited in claim 4, wherein each of said adjustment pieces is integrated with each of said control parts. 16. The nozzle adjustment member, as recited in claim 1, wherein each row of said long through holes of said nozzle cover is integrated into an integral slot. 17. The nozzle adjustment member, as recited in claim 1, wherein some of said long through holes are longer than other said long through holes. 18. The nozzle adjustment member, as recited in claim 1, wherein said pivot support is mounted with or without said nozzle tube therein optionally. 19. The nozzle adjustment member, as recited in claim 1, further comprising at least one belt connecting bottoms of said plurality of nozzle tubes. 20. The nozzle adjustment member, as recited in claim 1, further comprising at least one shaft tube extending downward arranged at an edge of an inner side of each row of said long through holes so as to mount into said pivot hole of said adjustment piece. 21.
