[0028] The diagonal parts at the bottom of the layered rack 1 are rotatably matched with threaded tubes 4, and the four threaded tubes 4 are respectively threadedly matched with four threaded rods 5. A transmission component 7 is installed in the layered rack 1, and the transmission component 7 cooperates with the four threaded tubes 4. A fixed frame 15 is installed on the top of the placement plate 2, and a plurality of limit rods 17 are movably matched in the fixed frame 15.

[0029] The application of one aspect of this embodiment is as follows: first, multiple layer racks 1 are stacked, and one layer rack 1 is placed on another layer rack 1, so that the four fixing blocks 6 enter the corresponding four fixing grooves 3 respectively, and the multiple layer racks 1 are stacked and used in turn. When it is necessary to adjust the distance between the two layer racks 1, the threaded cylinder 4 at the bottom of the layer rack 1 is rotated, and the rotation of the threaded cylinder 4 drives the threaded rod 5 to move, so that the threaded rod 5 drives the fixing block 6 to move and extend out. The rotation of one threaded cylinder 4 will mobilize the transmission component 7, and the transmission component 7 will drive the remaining three threaded cylinders 4 to rotate, and the positions of the fixing blocks 6 on the four threaded rods 5 can be adjusted at the same time, so that the distance between the two layer racks 1 is increased. When it is necessary to place a tissue culture bottle, the placement plate 2 is pulled out to place the tissue culture bottle in the fixing rack 15, and then the limiting rod 17 is used to limit the tissue culture bottle.

[0030] Among them, the placement plate 2 of the device can accommodate tissue culture bottles, cultivation boxes, etc., and can be used for potato tissue culture seedlings. The potato tissue culture bottles can better observe the growth of potato roots, and the potato cultivation boxes can be used to place soil and multiple seedlings for cultivation.

[0031] By means of the provided threaded barrel 4, the threaded barrel 4 can be rotated to drive the threaded rod 5 to move, and the threaded rod 5 drives the fixed block 6 to move, so that the distance between the layered racks can be adjusted as needed, which is convenient for placing tissue culture bottles for growth and cultivation. By means of the provided transmission assembly 7, when the user rotates one of the threaded barrels 4, the threaded barrel 4 can mobilize the transmission assembly 7, so that the transmission assembly 7 can drive the remaining three threaded barrels 4 to rotate, which is convenient for the user to adjust the positions of the fixed blocks 6 on the four threaded rods 5 at the same time. By means of the provided fixed frame 15 and the limiting rod 17, the multiple limiting rods 17 can divide the space in the fixed frame 15, so that the tissue culture bottles are placed in the fixed frame 15 for limited fixing, thereby reducing the situation where the tissue culture bottles fall when the placement plate 2 is moved, which is convenient for users to use.

Through the provided elastic blocks 11, after the fixing block 6 enters the fixing groove 3, the elastic blocks 11 can fix the fixing block 6, and the rounded corners on the top and bottom of the fixing block 6 can squeeze the elastic blocks 11.

[0035] like Figure 2-5 As shown, the bottom of the placement board 2 of this embodiment is provided with two T-shaped slots 12, and the bottom of the inner wall of the layered rack 1 is provided with two T-shaped sliders 13, which are respectively slidably matched with the two T-shaped slots 12, and a handle 14 is provided on one side of the placement board 2. By means of the provided handle 14, the placement board 2 can be pulled out by pulling the handle 14, so that the T-shaped slot 12 at the bottom of the placement board 2 slides along the T-shaped slider 13.

[0036] like Figure 5 As shown, a plurality of slots 16 are provided on the top of the fixing frame 15 of the present embodiment, and the limiting rods 17 are respectively matched with the plurality of slots 16, and limiting blocks 18 are installed at both ends of the limiting rod 17, and a protective pad 19 is sleeved around the limiting rod 17.
