[0025] like Figures 2 to 8 As shown, in another embodiment of the utility model, a guide groove 404 is provided between the support frame 401 and the guide frame 2, the partition plate 402 is snap-fitted and installed inside the guide groove 404, and slide grooves 405 are respectively provided at both ends of the front surface of the guide frame 2. Both ends of the floating plate 406 are movably installed inside the slide groove 405, and guide rods 407 are respectively installed inside the slide groove 405, and the rod bodies of the guide rods 407 are movably installed inside the floating plate 406, and connecting plates 410 are respectively installed at both ends of the placement box 409, and bolts 411 are installed between the connecting plates 410 and the guide frame 2, and a water storage tank 415 is provided at the lower end of the placement box 409, and the water storage tank 415 and the placement tank 412 are connected through each other, and the water storage tank 415 is connected to the placement tank 412.
