[0021] The limiting mechanism comprises a movable rod 9, a spring 11, an extension slot 8 and a limiting block 10. The movable rod 9 is movably inserted into the push plate 3, and the bottom end of the movable rod 9 is movably embedded in the top end position of the movable frame 4. The extension slot 8 is provided in the push plate 3, and there are two extension slots 8 symmetrically provided in the positions on both sides of the movable rod 9. The limiting block 10 is welded and fixed outside the movable rod 9, and there are two limiting blocks 10 symmetrically fixed in the positions on both sides of the movable rod 9. The spring 11 is welded and fixed between the movable frame 4 and the push plate 3, and the spring 11 is sleeved outside the movable rod 9. The limiting block 10 is matched with the extension slot 8. In use, the movable rod 9 is rotated, so that the limiting block 10 is aligned with the extension slot 8. Then the movable rod 9 is moved upward, so that the limiting block 10 passes through the extension slot 8, and at this time the spring 11 is compressed.

[0022] Working principle: When moving in use, the experimental box body 1 is moved through the movement wheel 2. When the experimental box body 1 moves to the destination position, the movable frame 4 is moved downward through the limiting mechanism, and then the movable frame 4 is fixed in position. The arc-shaped toothed block 5 is moved downward until it is meshed with the gear 6. In this way, the wheel shaft 12 is fixed in position, so that the movement wheel 2 is in a fixed state. When moving again, the arc-shaped toothed block 5 is moved away from the gear 6 through the limiting mechanism. In this way, the experimental box body 1 can be moved again, which is low in moving cost and simple and convenient to fix. In use, the movable rod 9 is rotated, so that the limiting block 10 is aligned with the extension slot 8. Then the movable rod 9 is moved upward, so that the limiting block 10 passes through the extension slot 8, and at this time the spring 11 is compressed. Then the movable rod 9 is rotated, so that the limiting block 10 is misaligned with the extension slot 8. The spring 11 is elastically deformed, so that the limiting block 10 is tightly attached to the top end of the push plate 3. The movable frame 4 is in a fixed state, and the gear 6 is in a separated state from the arc-shaped toothed block 5. When resetting, the spring 11 is elastically deformed, so that the arc-shaped toothed block 5 is in a meshing state with the gear 6. Thus, the experimental box body 1 can be fixed.
