The guide module 11 includes two arc-shaped guide grooves 11a corresponding to the two sliders 12, respectively. The two guide grooves 11a are symmetrically arranged and the centers of the two coincide with each other. The two sliders 12 are respectively slidably arranged in the two guide grooves 11a. Among them, the inner wall of the box body 1 is provided with a plurality of arc-shaped guide blocks, and the plurality of guide grooves 11a are opened on the plurality of guide blocks one by one.

[0039] When the shelf 4 rotates, the slider 12 at its end can be accommodated in the guide groove 11a and slide along the guide groove 11a, which effectively improves the rotation stability of the shelf 4; at the same time, the end of the guide groove 11a can block the slider 12 and limit the slider 12 to prevent the shelf 4 from rotating excessively and causing the culture on the shelf 4 to fall off.
