The protective shell 219 is displaced downward by the positioning plate 216, and the arc block 222 is displaced by the displacement of the protective shell 219. The arc block 222 is reset by the elastic force of the compression spring 221. Because the shape of the arc block 222 is set to be an arc, when the arc block 222 is reset, the deceleration block 224 will limit the arc block 222 to achieve the deceleration effect, thereby increasing the shock absorption effect, thereby protecting the water tank 205 from damage or influence.
