The water flow control structure of a water gun includes a movable control tube, stepwise positioning unit, oblique guide and resilient component. When the control tube is moved by the control component, it is turned by the oblique guide and stepwise positioning unit. Each time the first guide of the control tube coordinates with the position of the stepwise positioning unit, it makes the space between the stopper head of the control tube and the water control outlet of the water holder close or open in different degrees to control water flow. The entire control structure is hidden inside the water gun. The repeated movements of the control component can switch the water flow mode, which is convenient and practical.

I claim: 1. A water flow control structure of a water gun, said water flow control structure being placed on a predetermined part of said water gun to control on and off features and an amount of water flow, said water gun being comprised of a water inlet, a water outlet, a water holder between said water inlet and said water outlet, and a control component placed on a predetermined part of said water gun; said water flow control structure comprising: a control tube, being placed inside said water holder of said water gun, and being rotatable and moveable, said control tube being moved by said control component of said water gun and being moveable down from a first location to a second location, said control tube having a water channel placed inside thereof, said control tube facing an end of said water outlet, said end having a stopper head to stop a water control outlet inside said water holder to shut water flow off, said control tube having a first guide and a second guide placed on an outside thereof; a stepwise positioning unit, being placed inside said water holder, said stepwise positioning unit being comprised of sets of positioning slots having different heights and an oblique surface of said positioning unit, wherein said first guide of said control tube corresponds to said stepwise positioning unit, when said control tube is at said first location; an oblique guide, having sets of rings placed inside said water holder, wherein said second guide is guided by said oblique guide when said control tube is moved to a second positioning, making said control tube of said second guide turn to a predetermined angle; and a resilient component, restoring said control tube from a second position to a first position. 2. The structure defined in claim 1, wherein said control component of said water gun comprises a press handle and a linkage lever, said press handle having a top end thereof placed on a top end of a front side of said water gun, a bottom end of said press handle being pressed, said linkage lever being connected to a through hole in a middle of said water gun, said linkage lever being comprised of a vertical rod and two horizontal bars, a middle of said water gun having a through hole for a horizontal bar of said linkage lever to insert, a shoulder being placed on an outside of said control tube for the horizontal bar to place on, said vertical rod moving the horizontal bar when a bottom of said press handle is pressed in, said control tube being moveable from the first position to the second position. 3. The structure defined in claim 1, wherein said control component of said water gun is comprised of a press handle, said press handle being placed on a top of said water gun and being connected with said stopper head of said control tube by going through said water holder of said water gun, said press handle moving said control tube downward when said press handle is lowered. 4. The structure defined in claim 1, wherein said first guide is comprised of two protruding blocks at a 180-degree angle. 5. The structure defined in claim 1, wherein said second guide is comprised of protruding blocks in a circular fashion, a bottom of each block having an oblique surface corresponding to said oblique guide. 6. The structure defined in claim 1, wherein said oblique guide is comprised of a ring base, said ring base being positioned in said water holder. 7. The structure defined in claim 1, wherein said resilient component is comprised of a spring.
