When the shift lever 102 is inserted into the fixing groove 212, the shift lever 102 is prevented from being inserted into the connecting groove 211 by the action of the return spring 29, so that the spline shaft 91 can be axially retained in the holding portion 2.

In this embodiment, in order to facilitate a user to toggle the toggle lever 102, an end of the toggle lever 102 away from the limiting portion 101 is connected to a toggle button 103 through a snap connection.

When the spline shaft 91 is disengaged from the rotating ring 7, the rotating ring 7 may rotate by the action of external force. Also, the spline shaft 91 may rotate circumferentially under the self-vibration of the water gun. Further, it may happen that when the spline shaft 91 approaches to the side of the valve stem 514, the spline shaft 91 cannot be properly slid into the rotary ring 7 or cannot be properly fitted over the valve stem 514.

Therefore, the above problems can be solved by the following method and structure adjustments: referring to fig. 4, the axial position relationship among the spline shaft 91, the rotating ring 7 and the valve rod 514 is adjusted, specifically, when the spline shaft 91 slides to the end far away from the ball valve core 51, the spline shaft 91 is sequentially separated from the valve rod 514 and the rotating ring 7, that is, when the spline shaft 91 is re-assembled, the spline shaft 91 is firstly contacted with the rotating ring 7. The spline shaft 91 is pushed to abut against the valve rod 514 by shifting the shifting lever 102, and then the rotating ring 7 is rotated to carry out fine adjustment so that the spline shaft 91 can be sleeved on the valve rod 514.

Because rivers can impact the ball valve, if do not carry on spacingly to valve stem 514, can lead to ball valve case 51 to take place to rotate under the impact of rivers after integral key shaft 91 and valve stem 514 break away from each other. Therefore, referring to fig. 12, the elastic fixing member 11 is correspondingly disposed on the inner sidewall of the connection section 21, and the elastic fixing member 11 is disposed on the inner sidewall of the connection section 21. The elastic fixing member 11 includes a fastening portion 111, an elastic inclined portion 112 and a fixing portion 113 integrally connected in sequence, and the fixing portion 113 is fixedly connected to the inner side wall of the connecting section 21 by bolts.

Referring to fig. 12 and 13, when the spline shaft 91 and the valve rod 514 are separated from each other and are far away from each other, the elastic inclined portion 112 inclines to one side near the valve rod 514 along the direction from the fixing portion 113 to the direction near the ball valve element 51, and the elastic inclined portion 112 makes the clamping portion 111 always have a tendency of penetrating through the external spline of the valve rod 514, so that the circumferential limit of the valve rod 514 is realized, and the limit of the ball valve element 51 is further realized. When the spline shaft 91 is connected to the valve stem 514, the outer peripheral wall of the spline shaft 91 abuts against the elastic inclined portion 112 and deforms the elastic inclined portion 112 as the spline shaft 91 advances, so that the engaging portion 111 and the valve stem 514 are disengaged from each other. In this embodiment, the elastic fixing member 11 is preferably made of spring steel.

The implementation principle of the embodiment is as follows:

when the water yield of the water gun does not need to be adjusted for a long time (for example, the water gun is turned off for a long time or watered for a long time), the shifting knob 103 is shifted to one end far away from the spray head 3, and then the shifting knob moves along the directions of the connecting groove 211 and the fixed groove 212 until the shifting lever 102 is limited in the fixed groove 212, and at this time, no matter how the rotating ring 7 rotates, the valve rod 514 cannot rotate.

When the water yield of the water gun needs to be adjusted, firstly, the shifting lever 102 is shifted into the sliding groove 27, secondly, the rotating ring 7 is rotated to be finely adjusted so as to ensure the key connection between the spline shaft 91 and the rotating ring 7, then the spline shaft 91 is pushed to be mutually abutted against the valve rod 514 by shifting the shifting lever 102, and finally, the rotating ring 7 is rotated to be finely adjusted so that the spline shaft 91 can be sleeved on the valve rod 514, and at the moment, the rotating ring 7 is rotated to drive the valve rod 514 to be linked.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
