1. A jet valve spool, comprising: a spool housing provided with a cold water port and a hot water port thereon;a nozzle, disposed within said spool housing and having a cold water inlet communicated with a cold water passage of a valve through said cold water port, and a cold water outlet;a needle, adapted for being configured inside said nozzle, for coordinating with an inner cavity of said nozzle to form a cold water inflow space and coordinating with said cold water outlet to form a cold water jetting outlet; anda rotatable member, rotatably disposed on said spool housing in a sealing manner and forming an axial movable adaptation with said nozzle via an axial movement adjusting means, so as to allow a rotating movement of said rotatable member to be converted to an axial movement of the nozzle;wherein said needle is unmovable in the axial direction of said jet valve spool, and said nozzle is movable in the axial direction of said jet valve spool, and fluid flow rates of said cold water inflow space, said hot water port and said cold water jetting outlet are adjustable simultaneously by axially moving said nozzle;wherein said rotatable member is connected with said needle so as to drive said needle to rotate simultaneously; andwherein said spool housing coordinates with said nozzle via a rotation limiting part to prevent said nozzle from rotating relative to said spool housing, as said rotatable member drives said needle to rotate, and via said movement adjusting means to allow said nozzle to move in the axial direction of said needle relative to said spool housing. 2. The jet valve spool of claim 1, wherein said axial movement adjusting means comprises an internal thread formed on said nozzle, and an external thread formed on said rotatable member and adapted for being engaged with said internal thread; and the distance for which said internal thread is engaged with said external thread is larger than or equal to the distance for which said nozzle is able to move. 3. The jet valve spool of claim 1, wherein said rotation limiting part is a polygonal end portion formed on said nozzle, and the shape of said polygonal end portion matches with the shape of an inner wall of said spool housing. 4. The jet valve spool of claim 1, wherein said rotation limiting part comprises a flange and/or a guide groove circumferentially disposed on an outer circumferential surface of said nozzle, and a guide groove and/or a flange axially disposed on the inner wall of said spool housing and forming a movable adaptation with said flange and/or guide groove. 5. The jet valve spool of claim 1, wherein said cold water inlet and said cold water outlet of said nozzle have a pair of circumferential flanges formed therebetween extending radially outward, and said circumferential flanges allow a sealing element to be disposed therebetween, and a hot water segment of said nozzle located between said circumferential flanges and said cold water outlet is able to be communicated with a hot water passage of the valve. 6. The jet valve spool of claim 5, wherein said hot water segment is cylindrical in shape. 7. The jet valve spool of claim 1, wherein the diameter of said cold water outlet of said nozzle is 4 mm-6 mm. 8. The jet valve spool of claim 1, wherein said needle comprises a needle body, and a conical portion disposed on one end of said needle body and engaged with said cold water outlet of said nozzle, and said needle body is circumferentially provided with a supporting member, so as to allow outer surface of said supporting member to coordinate with the inner cavity of said nozzle, in order to limit the position of said needle body and to form a fluid passage on said supporting member, as said needle is disposed inside said nozzle. 9. The jet valve spool of claim 8, wherein said supporting member comprises a plurality of ribs uniformly and circumferentially arranged around said needle body and extending in the axial direction of said needle body, and each two said ribs have one said fluid passage formed therebetween. 10. The jet valve spool of claim 9, wherein said rib comprises a first rib part and a second rib part; and said first rib part is arranged towards said cold water inlet of said nozzle and has a radial dimension smaller than that of said second rib part, so as to coordinate with said inner wall of said nozzle to form said fluid passage, and an adaptation is formed between an outer surface of said second rib part and said inner cavity of said nozzle. 11. The jet valve spool of claim 10, wherein said nozzle has a groove formed on the inner wall thereof and corresponding to said second rib part, and said second rib part is adapted for being fitted in said groove and sliding in the axial direction of said nozzle. 12. The jet valve spool of claim 9, wherein the number of said ribs is three, four or six; and the sum of the cross section of all fluid passages formed between said ribs is larger than the cross section of said cold water outlet of said nozzle. 13. The jet valve spool of claim 8, wherein said supporting member of said needle body and said conical portion have a water pressurizing and mixing segment formed therebetween, and said water pressurizing and mixing segment is cylindrical in shape. 14. The jet valve spool of claim 13, wherein the diameter of said water pressurizing and mixing segment is larger than, or equal to, or slightly smaller than the diameter of said cold water outlet of said nozzle. 15. The jet valve spool of claim 8, wherein the diameter of said conical portion is larger at a root thereof and smaller at a front end thereof, and the conical degree of said conical portion is 10°-150°, and the length of said conical portion is smaller than or equal to the distance for which said nozzle is movable. 16. The jet valve spool of claim 15, wherein the conical degree of the cold water jetting outlet of said nozzle is larger than or equal to the conical degree of said conical portion. 17. The jet valve spool of claim 16, wherein the diameter of said conical portion is gradually reduced in a linear manner from said root to said front end. 18. The jet valve spool of claim 1, wherein the cold water pressure at said cold water inlet on said nozzle is always consistent with the cold water pressure at said cold water port on said spool housing, as said nozzle is moved in the axial direction of said jet valve spool. 19. A jet valve spool, comprising: a spool housing provided with a cold water port and a hot water port thereon;a nozzle, disposed within said spool housing and having a cold water inlet communicated with a cold water passage of a valve through said cold water port, and a cold water outlet;a needle, adapted for being configured inside said nozzle, for coordinating with an inner cavity of said nozzle to form a cold water inflow space and coordinating with said cold water outlet to form a cold water jetting outlet;wherein said needle is unmovable in the axial direction of said jet valve spool, and said nozzle is movable in the axial direction of said jet valve spool, and fluid flow rates of said cold water inflow space, said hot water port and said cold water jetting outlet are adjustable simultaneously by axially moving said nozzle; andwherein said needle comprises a needle body, and a conical portion disposed on one end of said needle body and engaged with said cold water outlet of said nozzle, and said needle body is circumferentially provided with a supporting member, so as to allow outer surface of said supporting member to coordinate with the inner cavity of said nozzle, in order to limit the position of said needle body and to form a fluid passage on said supporting member, as said needle is disposed inside said nozzle. 20.
