The restoring spring 44 provided on the protruding structure 43 can have a certain restoring force in a stretched state, so that the free end 42 can apply a certain extrusion force to the limiting groove 321, and thus a better fixing effect on the spray head 3 can be achieved.
Fig. 5 is a schematic diagram of a button shown in accordance with an exemplary embodiment. As shown in fig. 5, the button 2 includes a button cap 11, a hollow cavity 12, and an elastic member 121. Wherein, the first end of the hollow cavity 12 is connected with the button cap 11, and the second end of the hollow cavity 12 is an opening.

As shown in fig. 4, an inclined surface 47 is provided at a position of the stopper holder 4 that contacts the button 2. The shape of the inclined surface 47 is adapted to the conical surface of the hollow cavity 12 of the push button 2.
When the button 2 is pressed, the conical surface of the hollow cavity 12 of the button 2 is in contact with the inclined surface 47 on the limit bracket 4, and since the hollow cavity 12 has the conical surface, when the button 2 is pressed downwards, the limit bracket 4 is subjected to outward pressure, the limit bracket 4 is forced to be spread outwards, at this time, the fixed end 41 of the limit bracket 4 rotates around the rotating shaft 22, and the free end 42 of the fixed end rotates out of the limit groove 321, thereby releasing the fixing effect on the spray head 3, and the spray head 3 can be released.
When the button 2 is released, the button 2 is reset by the rebound of the pressed elastic member 121, thereby releasing the outward pressure applied to the stopper bracket 4. Simultaneously, the free end 42 moves towards the direction approaching the through hole 21 under the rebound action of the reset spring 44 on the protruding structure 43 of the limiting support 4, and is blocked by the reset limiting structure 23 in the moving process, so that the free end 42 stops moving, and the free end 42 is prevented from overlapping.
In the disclosed embodiment, the button 2 is provided with a button stop feature 111. Pressing the button 2, the wedge or conical surface end of the button 2 expands the spacing bracket 4, thereby moving the free end 42 of the spacing bracket 4. The elastic member 121 in the hollow chamber 12 is deformed by contraction. When the push button 2 is released, the hollow elastic member 121 is deformed and restored due to its own characteristics, thereby rebounding the push button 2. The free end 42 of the limit bracket 4 moves in the opposite direction. The reset purpose of the button 2 is achieved by the button limiting feature 111 on the button 2 forcing the button 2 in rebound to stop under the blocking action of the body 1.
In the embodiment of the present disclosure, the elastic member 121 may be a spring or a spring plate, for the purpose of achieving the rebound and return of the button 2, and is not limited to the spring or the spring plate.

The release and securement of the spray head of embodiments of the present disclosure may also be achieved.
Further, in the embodiment of the present disclosure, the return spring 44 may be replaced by a spring plate or a rubber band, etc., so long as the limit bracket 4 can rebound and achieve fixing and releasing of the spray head 3.
Further, in the embodiment of the present disclosure, the return limiting structure 23 is disposed on the body 1, and it is understood that the location of the return limiting structure 23 is not limited to the location illustrated by the schematic diagram in the embodiment of the present disclosure, and the schematic diagram is only a schematic symbol. The return limiting structure 23 can also be arranged on the free ends 42 of the limiting brackets 4, and mainly plays a role in limiting the closing of the two free ends 42 of the limiting brackets 4, avoiding covering up the through holes 21, thereby ensuring that the bottom end of the spray head 3 passes through the through holes 21, and further enabling the free ends 42 to enter the limiting grooves 321 of the spray head 3, and playing a role in fixing the spray head 3.

In the embodiment of the disclosure, the limiting support 4 is of a V-shaped elastic structure, the fixed end 41 is fixed on the body 1, and the button 2 is also arranged on the fixed end 41 side. By setting the V-shaped included angle of the limiting support 4, the free end 42 of the limiting support 4 enters the limiting groove 321 of the spray head 3 and fixes the spray head 3 in a state that the limiting support 4 is not affected by any external force. When the head 3 is released, by pressing the button 2, an outward pressure is applied to the spacing bracket 4, whereby the free end 42 of the spacing bracket 4 moves outward, so that the head 3 can be released. When the pressure from the button 2 is withdrawn, the free end 42 of the limit bracket 4 returns to the original position by the restoring property of the limit bracket 4, and the fixing effect on the spray head 3 can be realized again. In the embodiment of the present disclosure, the return limiting structure 23 is not required to be added to limit the free end of the limit bracket 4. In addition, the free end 42 can be reset by the deformation recovery characteristic of the limiting support 4, the fixing and the pressing of the spray head 3 can be realized, and the structure is further simplified without additionally arranging a reset spring 44.
