所述拉线600一端连接拉块310末端，另一端最好下垂。
拉线切换水路步骤：
步骤00，分水体200的堵球230密封出水终端130的第二分水孔133，此时机构出水腔体通过一进水孔240对齐接通第一分水孔133，机构第一出水功能出水，请查阅8、9；
步骤10，拉动拉线600，通过拉块310带动棘爪轴300正转；
步骤20，棘爪轴300带动上棘齿320正转，所述上棘齿320的一第一竖直面321作用在下棘齿210的第二竖直面211，带动下棘齿210正转，带动分水体200正转，此时复位体500储能，堵球230离开第二分水孔133；
步骤30，当分水体600转动90度之后，所述止位爪400顶抵止位齿220，以定位分水体600，所述堵球230位于第一分水孔和第二分水孔之间，此时，所述二进水孔240下端分别对齐接通二分水孔，机构第一出水功能和第二出水功能均出水，请查阅图10、图11；
步骤40，用户松释拉线600的拉动，所述复位体500复位，所述上棘齿320的第一倾斜导向面322沿第二倾斜导向面212滑动，当滑动至第二倾斜导向面212顶端，也即是和第三倾斜导向面213连接处时，沿着第三倾斜导向面213向下滑动（此时复位体可能还存在有弹力，所述弹力也作用棘爪轴300），并复位至原位置。
同理，用户能够将第二状态水切换至第三状态水，也即是，第二功能出水。
以上所述，仅为本发明较佳实施例而已，故不能依此限定本发明实施的范围，即依本发明专利范围及说明书内容所作的等效变化与修饰，皆应仍属本发明涵盖的范围内。
