       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0015]    According to the  FIG. 1  and  FIG. 2 , the connecting and fixing structure for a shower head in the present invention comprises a connector  1 , a main joint  2  and a movable fixing structure  3  to connect both above; 
         [0016]    The connector  1  is a cylinder forming on the back of the shower head A, communicating with the intake cavity A 1  of the shower head A; the connector  1  comprising an upper cylinder  11  and a lower cylinder  12  is a two-step stage column with thick above and thin down, thereinto a neck  111  is disposed in the middle of the upper cylinder  11 , and both of the upper edge and the lower edge of the neck  111  form a inclined leading face. The upper cylinder  11  above the neck  111  is disposed with a groove  13  to embed the airproof ring  4 ; 
         [0017]    The main joint  2  is connected with the outlet on the top of the wall to be a water passage, the inner diameter of the main joint  2  adapts to the outer diameter of the upper cylinder  1  of the connector  1 . The outer edge of the main joint  2  forms three steps of ladder growing thin, which are the upper  21 , middle  22  and lower  23  cylinder. The three cylinder turns to be a stage. Some symmetrical position holes  231 , whose bottom portion disposes an inclined face  232 , are disposed close to the middle of the lower cylinder  23  and a limit step  233  is disposed at the bottom of the lower cylinder  23 . 
         [0018]    The movable fixing structure  3  comprises a snap-fit  31 , a spring  32  and a sliding sleeve  33 ; 
         [0019]    The snap-fit  31  is a sleeve ring, and plurality of convex feet  311  are extended inwardly and upwardly from the bottom of the snap-fit. The convex feet  311  have an equal amount to the position holes  231 . The inner diameter surrounded by the end of the convex feet  311  is smaller than the outer diameter of the upper cylinder  11  of the connector  1 , and the outer edge of the bottom of the convex feet has steps. The snap-fit  31  hitches the top of the lower cylinder  23  of the main joint  2 , and the top of the snap-fit  31  abut against the step formed by the middle cylinder  22  and the lower cylinder  23 . Especially the convex foot  311  stretches inside to the position hole  231  of the lower cylinder  23  of the main joint  2  to be an elastic hook. Because of the plurality of the convex feet  311  the snap-fit  31  has, all of the convex feet  311  stretch inside to the position holes  231  of the lower cylinder  23  of the main joint  2  to be elastic hooks, so that the affect of the position is well; 
         [0020]    The sliding sleeve  33  is a cover column, whose inner diameter adapts to the upper cylinder of the main joint  2 . The bottom of the inner is disposed with flange ring  331 , whose inner diameter adapts to the outer diameter of the bottom of the snap-fit  31 . A plurality of position convex ribs  332  extends inside and downside from the flange ring  331 . As showed in the  FIG. 1 , the spring  32  place in the sliding sleeve  33  downwards, the bottom of the spring  32  abut against the flange ring  331 , and the sliding sleeve  33  hitches to the main joint  2  with the spring  32  from the bottom of the main joint  2  upwards; the position convex ribs  332  abut against the limit step  233  at the bottom of the main joint  2 , preventing the sliding sleeve  33  from shedding off the main joint  2 . And the top of the spring  32  push against the step formed by the upper  21  and middle  22  cylinders of the main joint  2 , so that the sliding bush  33  is movable in the main joint  2 . The convex feet  311  of the snap-fit  31  support alongside against the neck  111  of the connector  1 , and the side wall of the flange ring  331  of the sliding sleeve  33  abut against the outer edge at the bottom of the snap-fit  31  making it a fixation. 
         [0000]    As showed in the  FIG. 1  and  FIG. 3 , when going to fix the shower head to the main joint which connects to the outlet on the top of the wall, stick the connector  1  of the shower head directly to the inner cavity of the main joint  2 . As the convex feet  311  of the snap-fit  31  is disposed upwards from inner sidelong, the connector  1  can push the convex feet  311  transmute outwards when the connector  1  goes upwards. While the neck  111  of the connector  1  moves up to the position of the snap-fit  31 , the convex feet  311  of a hook is enclosing to the neck  111  and hanging the connector to be a fixation. That is the shower head A connecting to the outlet. Because of the airproof loop  4  disposed in the connector  1 , the cavity between the connector  1  and the main joint  2  is sealed avoiding leaking. 
         [0021]    As showed in the  FIG. 2  and  FIG. 3 , when going to remove the shower head A out of the main joint  2 , push the sliding sleeve  33  of the movable fixing structure  3  upwards comparatively to the main joint  2 , at the time the spring  32  is compressed energy. Pull the shower head at the same time, making the connector  1  moves down comparatively to the main joint  2 , the connector  1  would move down with the snap-fit  31 . With the two-way force, the flange ring  331  of the sliding sleeve  33  will abut against the interspace of the snap-fit  31 . The disposing of the step  312  could avoid the snap-fit  31  falling away from the sliding bush  33 . At the process of the connector  1  force upwards, the inclined face in the neck  11  of the connector  1  will push against the convex feet  311  of the snap-fit  31 . So that the convex feet  311  moves outwards sidelong back to the position holes  231  along the inclined plane  232  at the bottom of the position holes  231 , losing the hanging fixation of the connector  1 . Then the shower head removes out of the main joint. 
         [0000]    Stated thus, the present invention has a movable clipping structure by the coordination of a movable fixing structure  3  and a main joint  2  connecting to the outlet on the top of the wall. A neck  111  is disposed in the connector  1  which molds in the shower head A. When the connector  1  stretch to the main joint  2 , the movable fixing structure hangs on the main joint in a fixation. The configuration and the remove of the shower head would be more convenient and quickly.
