When the trolley needs to be moved, the extension length of the telescopic rods 15 is adjusted, and the pressing plate 14 is pressed on the top of the uppermost Z-shaped plate 3, so that the plurality of Z-shaped plates 3 are more stable during movement, and the trolley is prevented from colliding with other objects during transfer, which may cause the Z-shaped plates 3 to fall.

[0037] In another technical scheme, a hook 16 is arranged on one of the support rods, and a signboard 17 is hung on the hook 16. Specifically, the signboard 17 can be used to record the relevant information of the mother or the mother's egg laying on the trolley, for the operator to identify and obtain, thereby improving the practicability of the trolley.

[0038] In another technical scheme, a handle 7 is arranged on the containing groove 4 to pull the containing groove 4 to slide. Specifically, the containing groove 4 is provided with a first wall of a slide rod 18, a second wall perpendicular to the first wall of the containing groove 4, and a handle 7 arranged on the second wall close to the opening of the long strip-shaped hole 5.
