[0063] The limiting device 400 is set to rise after the extrusion force disappears, and limits the rotation of the driving device 500, so as to prevent the placement rack 600 from rotating or swinging when placing the culture dish and adding the nutrient solution, thereby facilitating the operation of the staff;

[0064] When the limiting device 400 is squeezed, it will release the restriction on the driving device 500, so that the driving device 500 can be started normally, and the driving device 500 is prevented from being triggered when the culture dish is placed and the nutrient solution is added;

[0065] The telescopic rod 300 is arranged to drive the local structure of the mounting platform assembly 200 to rotate through telescoping, so that the mounting platform assembly 200 is rotated and opened, which is convenient for placing the culture dish.

[0071] The lower frame 210 is fixed to the U-shaped frame 220 and provides space for the installation of the constant temperature device, the driving device 500 and the placement rack 600;

[0072] The arrangement of the polygonal through holes 230 provides space for the sliding and installation of the limiting device 400 , while limiting the rotation of the limiting device 400 .

[0076] The L-shaped plate 241 is driven to rotate on the telescopic rod 300, so that the mounting platform assembly 200 is opened to expose the placement rack 600. At the same time, when the L-shaped plate 241 contacts the U-shaped rack 220, the limiting device 400 is squeezed to release the restriction on the driving device 500, so that the driving device 500 can be started normally.

[0077] The sealing of both sides of the L-shaped plate 241 can be ensured by the sealing plate 242 .

[0087] The trigger head 450 is equipped with a sensor. When the sensor is squeezed, a control system releases the restriction on the driving device 500, so that the driving device 500 can be normally started. The control system can adopt an existing known system, and when the trigger head 450 is squeezed, the polygonal plug 410 is driven down. After the squeezing force on the sensor disappears, the driving device 500 is restricted from starting, so that the driving device 500 cannot be started.

[0093] Among them, a reducer is provided on the driving motor 510 to reduce the rotation speed of the main shaft 520 driven by the driving motor 510. When the driving motor 510 is started, it will drive the main shaft 520 to rotate back and forth. At the same time, the rotation angle of the main shaft 520 is less than 180°. The driving motor 510 can drive the main shaft 520 to rotate forward and reversely, and the culture dish is driven to swing back and forth through the back and forth rotation of the main shaft 520.

[0094] In some embodiments of the present invention, the anti-rotation device 530 includes:

[0095] A first arc-shaped plate 531, wherein a plurality of first arc-shaped plates 531 are provided and are evenly distributed in a circular array and fixed on the inner wall of the insertion hole 440;

[0097] In the state where the polygonal plug post 410 is in the ascending state, the first arc plate 531 and the second arc plate 532 are all at the same horizontal height, so that the rotation of the main shaft is restricted and interfered, and the main shaft 520 is prevented from rotating relative to the driving motor 510 when the driving motor 510 is in the closed state. In the state where the polygonal plug post 410 is in the descending state, the first arc plate 531 and the second arc plate 532 are at different horizontal heights and do not interfere with each other, so that the main shaft can rotate freely, and the driving motor 510 can be driven at the same time, so that the driving motor 510 can drive the main shaft 520 to rotate normally after starting;

[0098] in, Figure 1 The first arc plate 531 and the second arc plate 532 are all at the same level, and the spring 430 is in a non-forced state. Figure 4 The first curved plate 531 and the second curved plate 532 are at different levels, and the spring 430 is in a stretched state;

[0099] When the polygonal plug post 410 is in the ascending state, the ends of the first arc plate 531 and the second arc plate 532 that are close to each other are set in a triangular state, so that the first arc plate 531 and the second arc plate 532 can be normally staggered under extrusion.

[0100] In some embodiments of the present invention, the placement rack 600 includes:

[0101] A placement plate 610, which is detachably fixed on the outer side of the main shaft 520;

[0102] The placement through holes 620 are provided in plurality and are evenly arranged on the placement plate 610 in a circular array.

[0103] The placement plate 610 is arranged so that the culture dish is driven to rotate normally when the main shaft 520 rotates, and the placement through hole 620 is arranged so as to provide space for placing the culture dish.

[0104] Working method of the utility model:

At the same time, when the extrusion of the trigger head 450 disappears, the spring 430 drives the polygonal plug column 410 and the limit plate 420 to rise, so that the polygonal plug column 410 drives the first arc plate 531 and the second arc plate 532 to interlace, and the rotation of the main shaft 520 is limited, and then the culture dish is placed in the placement through hole 620;

[0106] When the culture dish is placed, the telescopic rod 300 is started, so that the telescopic rod 300 drives the L-shaped plate 241 to reset, the mounting platform assembly 200 is closed, and the trigger head 450 is squeezed during the reset, so that the sensor releases the restriction on the drive motor 510, so that the drive motor 510 starts normally under the control of the remote control. At the same time, when the trigger head 450 is squeezed, the polygonal plug column 410 and the limit plate 420 are driven to descend, so that the polygonal plug column 410 drives the first arc plate 531 and the second arc plate 532 to stagger, and the L-shaped plate 241 and the sealing plate 242 are squeezed and sealed with the lower frame 210 and the U-shaped frame 220;

[0107] Then, the driving motor 510 is started, so that the driving motor 510 drives the main shaft 520 to rotate, so that the main shaft 520 drives the placement plate 610 to rotate, and so that the placement plate 610 drives the culture dish to rotate back and forth.
