[0002] Many water outlets on the market have flow adjustment functions, and users can control the water output of the water outlets at any time. The push button flow adjustment structure is the most common flow adjustment structure, which is widely used in showerheads. When using it, the user can push the pusher with his thumb to adjust the flow while holding the showerhead. It is a very convenient flow adjustment structure, so it is deeply loved by consumers. At present, the push button flow adjustment structure on the market often adopts the method of driving the pusher to drive the swing rod, and the swing rod carries the flow adjustment shaft. Such a structure is very simple, but there are the following problems: 1. When the swing rod is in the vertical state of the pusher, the flow adjustment state change speed brought by the pusher is the largest, that is, the above-mentioned flow adjustment structure has the problem of uneven adjustment speed, and it is difficult for users to accurately adjust the flow; 2. Due to the uneven flow adjustment speed, the user's force is also uneven during the pushing process of the pusher, which brings a bad experience to the user; 3.
