Among the figure: 10 water pistol bodies, 11 handle pipes, 12 outlet pipes, 13 groove seats, 131 side plates, 132 holes, 14 nose bars, 15 bodys, 16 water pipes connect the hole, 17 rooms, 18 waterways, 19 rubber sleeves, 20 push rods, 21 enlarge head end, 22 bodies of rod, 23 conical points, 24 springs, 30 stopcocks, 31 sealing collars, 32 springs, 33 mesh plates, 40 directed buttons, 41 sleeve pipes, 42 hook sheets, 43 tooth row plates, 44 long guide holes, 45 springs, 50 control buttons, 51 plate bodys, 52 projections, 53 horizontal guide grooves, 54 retaining edges, 55 side plates, 56 grades of posts, 57 card edges.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is by water jet column body 10, push rod 20, stopcock 30, directed button 40 and control button 50 are formed, wherein: water spray frame body 10 is communicated with outlet pipe 12 by handle pipe 11 tops and constitutes, there is groove seat 13 handle pipe 11 front sides, specially nose bar 14 is arranged in the groove seat 13 near the top, groove seat 13 inner faces protrude a body 15 near the bottom, body 15 and handle pipe 11 internal communication, handle pipe 11 inside upwards form water pipe successively and connect hole 16 from the bottom, room 17 and aperture are less than the waterway 18 of room 17, and water pistol body 10 outsides are coated with rubber sleeve 19; Push rod 20 1 ends are for enlarging head end 21, and extend the body of rod 22 than minor diameter, its terminal conical points 23 that forms, during assembling, push rod 20 can be penetrated spring 24 inside, the body of rod 20 with push rod 20 is inserted in the body 15 of 13 bottoms, groove chamber from conical points 23 again, and makes spring 24 other ends be enclosed within body 15 outsides; Stopcock 30 is room 17 inside of inserting handle pipe 11, stopcock 30 tops cover encloses a sealing collar 31, the formula of can blockading is opened the junction of room 17 and waterway 18, stopcock 30 tops are near body 15 the inners of handle pipe 11 groove seats 13, spring 32 can be inserted in its bottom, so that water pipe connects the affixed mesh plate 33 in 16 tops, hole and room 17 junctions, and the external diameter that stopcock 30 and spring 32 are positioned at room 17 inside, stopcock 30 is slightly less than the aperture of room 17; Directed button 40 inside protrude out a sleeve pipe 41, and it is relative with the nose bar 14 of groove seat 13, respectively there is a hook sheet 42 two sides of directed button 40, its bottom surface upwards forms the inclined-plane by the outer end gradually to the inner, its central authorities form a tooth row plate 43, directed button 40 bottom surfaces are positioned at tooth row plate 43 both sides and form long guide hole 44, during assembling, can make the sleeve pipe 41 of directed button 40 inside overlap an end that encloses spring 45 earlier, again directed button 40 is inserted handle pipe 11 groove seats 13 inner face tops, so that spring 45 other end covers are trapped among nose bar 14 outsides of groove seat 13 inner faces; The both sides on control button 50 tops upwards respectively form a relative plate body 51, plate body 51 lateral surfaces form projection 52 near the interior angle on top, its medial surface forms horizontal guide groove 53, the horizontal guide groove 53 terminal retainings that seal near the formation of plate body 51 front sides are along 54, connect the front side board 55 inner faces formation shelves post 56 of key 50 in addition in control, form card again on front side board 55 tops along 57, during assembling, control button 50 can be inserted groove seat 13 inside, so that hold location button 40 between two plate bodys 51, and utilize the projection 52 of two plate bodys 51 and the hole 132 of groove seat 13 top biside plates 131 to articulate, the hook sheet 42 of at this moment directed button 40 two sides enters respectively in the guide groove 53 of 50 liang of plate body 51 medial surfaces of control button, the card on control button 50 front side boards 55 tops along 57 with tooth row plate 43 bridle joints, nose bar 14 front ends of groove seat 13 enter in the sleeve pipe 41 of directed button 40, the conical points 23 of the bumping post 56 ejection push rods 20 of control button 50 front side boards 55 inner faces touches with the subsides of handle pipe 11 inner stopcocks 30 tops.

As shown in Figure 3, when the sealing state, directed button 40 and control button 50 all are not pressed into to groove seat 13 inside, therefore, it is downward to the inner interlock stopcock of handle pipe 11 30 that control button 50 can not promote push rod 20, and at this moment, stopcock 30 is subjected to the elastic force of bottom spring 32 and goes up closedtop and close waterway 18, therefore, water can not enter outlet pipe 12.

As shown in Figure 4, when a large amount of water outlet, directed button 40 and control button 50 can be pressed into to groove seat 13 inside simultaneously, because of being horizontal reciprocating displacement operation, control button 50 tops and groove seat 13, directed button articulates, therefore controlling button 50 bottoms is the swing mode and operates, after directed button 40 and control button 50 are pressed into simultaneously, control button 50 utilize front side board 55 top cards along 57 with tooth row plate 43 engagement of directed button 40 bottom surfaces, therefore can make control button 50 and directed button 40 location simultaneously and can not reply.At this moment, the conical points of push rod 20 23 promotes stopcocks 30 fully downwards, and the gap that makes sealing collar 31 amplify waterways 18 can intake in a large number and finishes the control operation of a large amount of water outlets.As shown in Figure 5, when need a small amount of water outlet or fine setting water yield, can earlier control button 50 be pressed into suitable distance slightly to groove seat 13 inside, so that the card on front side board 55 tops keeps appropriate gap with the tooth row plate 43 of directed button 40 bottom surfaces and does not mesh along 57, therefore push rod 20 utilizes terminal tapered clamp 23 inclined-planes can adjust by stopcock distance downward or upward, be scalable or dwindle the water inlet gap of waterway 18, when water yield to be painted is suitable, control button 50 is suppressed motionless, and the front side board 55 top cards of the tooth row plate 43 of the directed button 40 that is pressed into simultaneously and control button 50 end and can not reset along 57 cards, like this, promptly finish operation a large amount of or the fine setting water yield.When the water spray bolt does not use, therefore directed button 40 is subjected to the elastic force of spring 45 and overhanging, and utilizes the hook sheet 42 of two sides to block the retaining of 50 liang of horizontal guide groove 53 ends of plate body 51 inner faces of control button along 54,, directed button 40 can not come off, and can reach the practical function of simple and easy control water pistol water yield.
