[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Please see Figures 1-4 In this embodiment of the present invention, an adjustment device for rapid propagation of agricultural tissue culture seedlings includes a support base plate 1. Two sets of uprights 2 are symmetrically welded to the top of the support base plate 1. A rotating bracket is hinged to the top of each set of uprights 2. Multiple sets of equally spaced placement racks 3 are rotatably installed between the two sets of rotating brackets. A buckle assembly for positioning the rotating bracket is installed on the uprights 2. The bottom of the two sets of buckle assemblies is connected to the same lifting assembly through a hinged movable rod 4. A sliding groove 5 is provided inside the uprights 2 for the lifting assembly to move up and down.

[0024] When using the adjustment device for rapid propagation of agricultural tissue culture seedlings, the interior of the placement rack 3 can be used to place the seedlings for rapid propagation. When the operator pulls up the lifting component, the lifting component can drive two sets of buckle components to open synchronously through the movable rods 4 at both ends. Rotating the rotating component can drive multiple sets of placement racks 3 to rotate synchronously, which can easily unfold multiple sets of placement racks 3 laterally, so that the seedlings placed inside each set of placement racks 3 can receive good light. After the rotating bracket is rotated to a suitable angle, the buckle components can automatically reset and fix it. When the device needs to be moved or stored, the rotating bracket can be rotated to rotate multiple sets of placement racks 3 to the same vertical line, reducing the overall space occupied by the adjustment device.

[0025] In one embodiment, the rotating support includes a frame rod 6 hinged to the top of the upright 2 at its middle. A semi-circular positioning ring 7 is integrally formed on the frame rod 6. A connecting post 8 rotatably connected to the placement frame 3 is welded to one side of the frame rod 6. The positioning ring 7 has multiple sets of round holes 9 that match the buckle assembly. The buckle assembly includes a first slide rod 10 that is slidably connected to the upright 2. The first slide rod 10 slides through one set of round holes 9 in the positioning ring 7. A push-pull plate 11 connected to the movable rod 4 is welded to the end of the first slide rod 10. A first spring 12 sleeved on the outside of the first slide rod 10 is installed between the push-pull plate 11 and the upright 2.

[0026] The movable rod 4 pulls the push-pull plate 11 to move left and right. The push-pull plate 11 can drive the first slide rod 10 to move and the first spring 12 to extend and retract, moving the first slide rod 10 to the outside of the positioning ring 7. The operator can rotate the frame rod 6 to drive the positioning ring 7 and the placement frame 3 to rotate. After the placement frame 3 has rotated to the appropriate position, the external force on the lifting assembly is removed. The first spring 12 resets the first slide rod 10, the push-pull plate 11 and other structures to reset. The first slide rod 10 is embedded in the corresponding round hole 9, which can facilitate the quick adjustment of the device.

[0027] Furthermore, a second slide rod 13 is welded onto the push-pull plate 11 and slides through the upright rod 2. A baffle 14 is detachably installed at the end of the second slide rod 13 away from the push-pull plate 11. A second spring 15 is installed between the push-pull plate 11 and the upright rod 2 and sleeved on the outside of the second slide rod 13. The movement of the push-pull plate 11 can simultaneously drive the second slide rod 13 and the baffle 14 to move, which can improve the stability of the movement of the buckle assembly and limit the range of motion of the first slide rod 10 and other structures. The push-pull plate 11 drives the second spring 15 to extend and retract, which can conveniently assist the quick reset of the first slide rod 10.

[0028] Based on the above embodiments, specifically, the lifting assembly includes a lifting plate 16 that is slidably installed inside two sets of sliding grooves 5. A limiting rod 17 that slides through the lifting plate 16 is welded between the upright 2 and the supporting base plate 1. The operator can pull up the lifting plate 16. The lifting plate 16 can simultaneously drive the two sets of buckle assemblies to move through the movable rods 4 at both ends, improving the convenience of device adjustment. The limiting rod 17 can also improve the stability of the lifting plate 16 moving up and down.

[0029] Furthermore, the lifting assembly also includes a third spring 18 installed between the lifting plate 16 and the support base plate 1. The third spring 18 is sleeved on the outside of the limiting rod 17. The lifting plate 16 can drive the third spring 18 to extend and retract, which facilitates the rapid reset of the auxiliary lifting plate 16, the movable rod 4 and the push-pull plate 11 and other structures.

[0030] The bottom of the support base plate 1 is equipped with casters 19 at the four corners, which makes it easy for staff to move the device. The uprights 2 are welded to the support base plate 1 with two sets of diagonal braces 20, which can improve the overall support strength of the device. The bottom of the placement rack 3 has multiple sets of equidistant drainage holes 21 to facilitate drainage of the seedlings inside the placement rack 3.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
