This scheme is convenient for height-adjusting stopper's height, and the pressure spring makes the stopper offset tightly with the top of bolt all the time.
Further, still be equipped with the baffle that is used for preventing the culture solution to splash on the fixed establishment, the both sides of baffle are fixed in respectively on first spacing claw and the second spacing claw.
This scheme can further prevent the mixing in-process, has the condition that the culture solution splashes from the culture dish, has avoided the extravagant condition of culture solution, has improved the utilization ratio of culture solution.
Furthermore, the baffle is provided with an observation port.
The scheme facilitates observation of the mixing condition in the culture dish during the mixing process, and facilitates judgment of whether mixing needs to be continued.
Further, the limiting mechanism is a fan-shaped annular sliding groove, and the central angle corresponding to the fan-shaped annular sliding groove is 10-30 degrees; the driven gear is an incomplete gear, a stop bulge is fixedly welded on the driven gear, and the stop bulge is arranged in the sector annular sliding groove in a sliding mode.
This scheme makes driven gear's rotation range and spacing claw's rotation range be correlated with, has avoided the condition of spacing claw and driven gear interact, and this scheme simple structure is convenient for process moreover.
Further, the rotation range of the stop protrusion in the fan-shaped annular sliding groove is 10 degrees.
The limiting claw in the scheme has a small rotating range, so that when the driving shaft rotates in a reversing mode, the first limiting claw and the second limiting claw can be rapidly switched and fix the culture dish.
Further, a bearing is arranged between the driving shaft and the tray.
The arrangement of the bearing reduces the friction force when the driving shaft and the tray rotate relatively.
