     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0039]      FIG. 1  shows an embodiment of the wall hanging bathroom article, which is a towel rack.  FIG. 2  shows another embodiment of the wall hanging bathroom article, which is a towel ring. Both the towel rack and the towel ring are respectively provided with a stabilizer blade  100 . The stabilizer blade  100  is connected to the wall hanging fixing device in accordance with embodiments of the present invention. Structure of the wall hanging fixing device is further described with the towel rack as an example. 
         [0040]    The following description of embodiment 1 is made with reference to  FIGS. 3   a - 10 . 
         [0041]    The present invention provides a wall hanging fixing device that includes a decoration cover  210 . A hanging member  220  is provided inside the decoration cover  210 , and the hanging member  220  is fixed on a supporting seat  260  in the inner side of the decoration cover  210  with screws  250 . The hanging member  220  is provided with a hanging connection groove  222  which is fit with a supporting member. The hanging connection groove  222  is arranged inside the jack  221  of the supporting member. The fixing device is also provided with a movable member  230  that can move towards or away from the hanging connection groove  222 . The movable member  230  and the hanging member  220  can match up and clamp the supporting member in the hanging connection groove  222 . The fixing device is also provided with a bolt  240  fixed axially with a bolt head  242  positioned on an edge of the decoration cover  210  which is provided with an open pore  210  matched to the bolt head  242 . The movable member  230 , subject to a threaded connection to the bolt  240 , moves towards or away from the hanging connection groove  222  when driven by the bolt  240 . A nut  231  is provided inside the movable member  230  and is subject to a threaded connection to the bolt  240 . 
         [0042]    In an embodiment shown in  FIGS. 3   a - 8 , the hanging member  220  is provided with a hanging connection groove  222 . The supporting member clamped by the movable member  230  moves upward. Based on this, the hanging connection groove  222 , instead of at the edge of the decoration cover  210  is arranged on an upper side in the center of inside of the decoration cover  210 . In this way, displacement due to clamping motion of the movable member  230  can be shortened, and interference with connection between a stabilizer blade  100  and the decoration cover  210  can be avoided. 
         [0043]    A clamping part  232  matched between the movable member  230  and the hanging connection groove  222  is wedge-shaped. In this way, the fixing device can be clamped on the supporting member, and the fixing device can also be completely clamped on the supporting member in the axial direction along the decoration cover  210 , thus preventing the fixing device from loosening. 
         [0044]    In the present invention, the wall hanging fixing device is provided with an axially positioning element of the bolt  240 , which is divided in half. One half body  291  is molded on the hanging member  220  or serves as an independent part. The other half body  292  is connected to the half body  291  by screws  293 , constituting an axially positioning element which is connected to the hanging member  220 . In this way, the bolt  240  is axially positioned and matched up with the axially positioning element, and a bulge loop  241  on the bolt  240  is stuck in a locating slot  290  in the axially positioning element. Thus, the bolt  240  is connected with the hanging member  220 , and the movable member  230  is subject to a threaded connection with the bolt  240 . In this way, the hanging member  220 , the bolt  240  and the movable member  230  in the fixing device are connected into a whole, and are used as wildcard units and connected with decoration covers of different wall hanging bathroom articles. This design reduces manufacturing cost of the wall hanging fixing device and of the decoration covers, and further simplifies assembly work. 
         [0045]    The hanging member  220 , shaped like a plate, serves as a cover plate of the open pore inside of the decoration cover  210 . In one embodiment, a flat shape feature of the decoration cover  210  is used, and axial rotation of the movable member  230  is restricted by an inner wall of the cover plate of the decoration cover  210  and by the hanging member  220 . 
         [0046]    Under the technical scheme, the supporting member can directly adopt an expansion bolt  270 , rendering it unnecessary to use other parts as the supporting member. 
         [0047]    Referring to  FIGS. 9-10 , the hanging member  220  is provided with two paratactic hanging connection grooves  222 . The supporting member clamped by the movable member  230  moves upward. Based on this, both the hanging connection grooves  222  are symmetrically arranged on both upper sides in the center of the decoration cover  210 , which not only makes the fixing device more stable during installation but also makes fixation strength higher after installation. Similarly, lifting stroke of the movable member  230  can be shortened, and interference with connection between the stabilizer blade  100  and the decoration cover  210  can be avoided. Accordingly, the movable member  230  is provided with two clamping parts  232  respectively matched to both the hanging connection grooves  222 . Other structures of the embodiment shown in  FIGS. 9-10  are identical to those of the embodiment shown in  FIGS. 3   a - 8 .
