The first shaft portion  33  of the first adjustable unit  3   a  is put around the first shaft receiving portion  32  of the second adjustable unit  3   b , the second shaft portion  31  o the second adjustable unit  3   b  is put around the second shaft receiving portions  221   a ,  221   b  of the connecting member  2 . 
     A combined first adjustable unit  3   a  and second adjustable unit  3   b  is shown in  FIG. 4 . The first shaft portion  33  of the first adjustable unit  3   a  is a conical entity having a wedge  331  around its circumference, and end of the threading portion  34  shapes into a first expansion portion  321 . The first shaft receiving portion  32  of the second adjustable unit  3   b  is equipped with a wedge bar  321  across its inside diameter and a spacer  322 . After the conical body of the first shaft portion  33  is inserted smoothly into the first shaft receiving portion  32 , the wedge  331  operates to hinge on the wedge bar  321 , whereas the first expanding portion  341  operates to press onto the spacer  322  to establish a blocking position; 
     The second shaft portion  31  of the second adjustable unit  3   b  is a conical entity having a wedge  331  around its circumference, an end of the second shaft portion has a second expanding portion  312 . A joiner  222  and a wedge bar  321  are disposed on the inner diameter of the second shaft receiving portions  221   a ,  221   b  of the connecting member  2 . After the conical body of the second shaft portion  31  is inserted smoothly into the second shaft receiving portions  221   a ,  221   b , the wedge  311  operates to hinge on the wedge bar  223 , whereas the second expanding portion  312  works to press onto the second shaft receiving portions to establish a blocking position; 
     The sprinkle head  35  is generally set out to have a substantially cylindrical outer surface, comprising a first reservoir  251 , a second reservoir  352 , and slotted plate  37  plug  38  appropriate for insertion into the reservoir. The aperture located at the center of the outer surface of the sprinkle head is a nozzle  353 , which are used for locking the protruded portion  371  of the slotted plate  37 . A second reservoir  352  is installed at the bottom part of the first reservoir  351 . The first reservoir  351  has an inner threading, and the second reservoir  352  has an inner pressing surface, for which an aperture passing through the sprinkle head  35  of the inner pressing surface is a nozzle  353 ; 
     The plug  38  has a first section and a second section, the diameter of the first section is larger than that of the second section, the cylindrical part of the first section extends to reach the second section, a water inlet channel  381  is disposed on the first section that is close to the second section. There is at least one water inlet channel  381 , and is evenly distributed in a circling fashion, the second section has more than one water outlet channel  382 . In the current embodiment, two channels are set out to pass by each other, and the distal end surface extending to the second section is bent to form two staggered lateral channels  382   a    382   b , the lateral channels  382   a ,  382   b , the terminal ends of the lateral channels  382   a ,  382   b  stop at the outer diameter of the recess of the slotted plate  37 , the width of the water channel of the water outlet channel  382  is smaller than the water inlet channel, so that the decrease in space can make the water flow entering into the reservoir turn from large to small in such a way to create high water pressure. Whereby, water flow passes through the hole  372  of the slotted plate  37  before passing though the nozzle  353  to instantly release water pressure, so as to finally create drizzle type water splash; 
     The slotted plate  37  is a circular plate, which has on an edge a protruded portion, the protruded portion  371  is a circular protrusion, the maximum outer diameter of the protruded portion  371  is larger than the aperture width of the nozzle  353 , the circular outer diameter of the highest point of the protruded portion  371  is smaller than the aperture of the nozzle  353  for pressing against the aperture edge of the nozzle  353 , an opposite back surface of the protruded portion  371  is a recess, a center of the recess  371  is a fine-sized hole  372 , the outer diameter of the slotted plate  37  is minorly smaller than the inner diameter of the second reservoir  352 , which is configured to allow the slotted plate  37  to press on the inner top surface before letting the plug  38  to hold after the slotted plate  37  is placed inside the second reservoir  352 . The fine-sized hole  372  works to make water passing therefrom form into drizzle type water splash, the distal end of the first section of the plug  38  presses on the flanged portion  343  of the inner diameter of the threaded portion  34  of the first adjustable unit  3   a , so as to stabilize the plug  38  to prevent it from detachment from the first reservoir  351 ; 
     By the above disclosure of the units and parts, the adjustment movement thereof can be realized as shown in  FIG. 5  and  FIG. 6 . The first adjustable unit  3   a  can move in a radial direction that is relative to the second adjustable unit  3   b , the second adjustable unit  3   b  can move in a radial direction that is relative to the connecting member, also, multiple angle spray direction is possible with the relative disposition of the sprinkle head of the first adjustable unit  3   a.    
     The adjustable member  3  of the current invention is not particularly limited to the drawings for the current invention&#39;s embodiments, ball valves can be used as the adjustable unit, or the connecting member  2  and the second adjustable unit  3   b  can be combined into a single body part, and the first receiving portion  21  of the connecting member  2  is an adjustable shaft receiving pipe, the adjustable unit can be one or more than one in terms of quantity.
