[0031] In specific implementations, such as Figure 3 and Figure 5 As shown, the partition plate 2 is equipped with an installation component 5. The installation component 5 includes a sliding cavity 51, a guide block 52, a rotating cylinder 55, and a mounting base 59. The sliding cavity 51 is located inside the bottom end of the partition plate 2, and the guide block 52 is slidably connected inside the sliding cavity 51.
