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. 3a-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.
