The assembly groove 2B is disposed in the inner frame 21 and configured to accommodate the driving assembly 3. It should be noted that the assembly groove 2B is provided with an opening communicating with the through hole 2A, and the forming direction of the opening is perpendicular to the axis of the through hole 2A.
The driving assembly 3 includes a moving member 31 and an elastic member 32.
The moving member 31 is accommodated in the assembly groove 2B and cooperates with the assembly groove 2B through inclined surfaces such that the moving member 31 is driven to displace obliquely while facing the through hole 2A and urge against the peripheral wall of the lifting rod. It should be noted that the moving member 31 includes an operating portion 311, a connecting portion 312 and an urging portion 313 that are informed integrally. The operating portion 311 is cylindrical, and a free end 311A thereof is exposed out of the pedestal 2 for a user to press. Of course, the free end 311A can further be flushed with the outer shell 22, and the user can press the free end 311A inwards with a finger. The other end of the moving member 31 is located in the pedestal 2 and urges against the elastic member 32. To guarantee that the elastic member 32 would not deviate in the moving process, the operating portion 311 is internally provided with a hole 311B for accommodating and guiding the elastic member 32. A surface of the pedestal 2 facing the hole 311B is provided with a guide column 23. One end of the elastic member 32 is placed in the hole 311B by urging against an inner bottom wall of the hole 311B and the other end thereof is sleeved on the guide column 23.
A side wall of the connecting portion 312 forms an inclined surface 312A, and the inclined surface 312A is fitted with a guiding surface 2C on the inner wall of the assembly groove 2B. The guiding surface 2C is formed by the inner wall of the assembly groove 2B obliquely extending towards the through hole 2A. As the inclined surface 312A and the guiding surface 2C move relatively, the connecting portion 312 moves back and forth relative to the through hole 2A.
The urging portion 313 moves along with the connecting portion 312 to urge against the periphery of the lifting rod. It should be noted that the urging portion 313 can either directly urge against the outer wall of the lifting rod or urge against the outer wall of the lifting rod by providing with other soft components. In the embodiment, the end of the urging portion 313 facing the lifting rod is internally provided with a cavity 313A. The cavity 313A is configured to accommodate a rubber mat 4. The rubber mat 4 thus moves along with the urging portion 313;

Two ends of the elastic member 32 act on the moving member 31 and the inner frame 21 respectively;
The through hole 2A is provided with a stopping rib 5 on an inner peripheral wall away from the moving member 31. The stopping rib 5 extends along the axial direction of the through hole 2A and cooperates with the moving member 31 to clamp the lifting rod. Several stopping ribs 5 can be arranged, and the stopping ribs 5 are spaced apart along the radial direction of the through hole 2A. In the embodiment, there are six stopping ribs 5, where two stopping ribs are facing the urging portion 313 and the rest four are arranged opposite in pairs and are arranged at angles of 90° relative to the urging portion 313.

The inner frame 21 is assembled to the showerhead base 1 through a connecting structure 6. The connecting structure 6 includes a positioning member 61 and a locking member 62. One end of the locking member 62 successively penetrates through the showerhead base 1 and the positioning member 61 and then is in threaded connection with the inner frame 21. The positioning member 61 and the inner frame 21 are in rotation-stopping fit. In addition, a periphery of the positioning member 61 is evenly provided with several gear teeth 610, and the gear teeth 610 cooperate with position-limiting teeth (not shown in the drawings) annularly arranged on an inner circumferential surface of the showerhead base 1, so as to limit rotation of the showerhead base 1 and enhance the user's sense of gear shifting during rotation.
During assembly, (1) one end of the elastic member 32 is sleeved on the guide column 23 in the inner frame 21; (2) the rubber mat 4 is placed in the cavity 313A of the urging portion 313 of the moving member 31; (3) the moving member 31 is placed in the assembly groove 2B, so that the elastic member 32 is accommodated in the hole 311B of the operating portion 311 and the inclined surface 312A of the connecting portion 312 contacts the guiding surface 2C; (4) the operating portion 311 is pressed, so that the elastic member 32 is compressed, the outer shell 22 is then sleeved on the peripheral wall of the inner frame 21; (5) the through hole 2A in the outer shell 22 is aligned with the through hole 2A of the inner frame 21, and the free end 311A of the operating portion 311 is exposed out of the outer shell 22; (6) the positioning member 61 is sleeved onto a protrusion at the end of the inner frame 21, and then the showerhead base 1 is sleeved onto the end portion of the inner frame 21 and is locked by the locking member 62; (7) the movable holder penetrates through the end of the lifting rod, so that the several stopping ribs 5 in the through hole 2A urge against the peripheral wall of the lifting rod. When the assembly is completed, under the action force of the elastic member 32, the moving member 31 has a tendency of moving obliquely towards the direction of the lifting rod and urges against the lifting rod through the rubber mat 4, so as to cooperate with the stopping ribs 5 to limit the position of the movable holder on the lifting rod.
During use, the user only needs to press the free end 311A of the operating portion 311 of the moving member 31 to adjust the movable holder according to the actually needed height. At the time, the moving member 31 moves obliquely downwards along the guiding surface 2C and compresses the elastic member 32. As the urging portion 313 moves obliquely downwards along the moving member 31, the rubber mat 4 accommodated in the cavity 313A is separated from the lifting rod, the movable holder thus is relieved and can slide up and down on the lifting rod. After being adjusted to a proper position, remove the loading force of the movable holder, the movable holder then can be fixed to the lifting rod again. At the time, under the action force of the elastic member 32, the moving member 31 moves towards the direction of the lifting rod, and the urging portion 313 moves obliquely upwards along the moving member 31, and the rubber mat 4 accommodated in the cavity 313A then urges against the lifting rod. The lifting rod being urged against by the several stopping ribs 5 and the rubber mat 4 is fixed to the position adjusted to.
