The rotation post 325 may rotate the drive chain. Thus, by driving the rotation post 325 to rotate, the rotation chain 324 can be driven to rotate, and then the driving shaft 311 is driven to rotate.
The workflow of the present invention is described below in conjunction with the above-described structure. When the embryo inserted in the drawer of the case 1 needs to be checked.
The first step, pulling the handle 2261 to guide the reset assembly to start, wherein the limit tenon block 229 limits the fixed tenon block 228, and then the drawer 2 is pulled out of the box 1, so that the embryo in the drawer 2 can be observed; at this time, since the second push rod 216 and the first push rod 215 are not abutted any more, the protection cover 10 is moved downward to close the drawer before the drawer 2 is completely withdrawn from the case 1, so that the embryo can be observed through the transparent protection cover; at the same time, the driving rod 223 is retracted by the first spring 224, and the second push rod 216 is also retracted simultaneously.
In the second step, the drawer 2 is inserted back into the case 1, and at this time, the time for lifting the jack is determined according to the time for withdrawing the drawer 2 from the case 1 in the first step. In detail, the fixed housing 314 is moved by the longitudinal moving device, so that the fixed housing 314 drives the driving gear 312 to move on one side of the driven gear 315, and the driving gear 312 is always abutted against the driven gear 315 under the pushing of the sixth spring.
Third, the fixing frame 323 is moved downward by the triggering device, and the rotating chain 324 and the driving gear 326 are separated from each other, so that the driving shaft 311 can rotate.
Fourth, since the torsion spring is provided on the driving shaft 311, the driving shaft 311 drives the driven gear 318 after the driving shaft 311 is disengaged from the rotating chain 324.
Fifth, after the triggering device pushes the fixing frame 323 to move downwards, the limiting crank 243 is pressed immediately, so that the limiting device does not limit the rotating disc 237 any more, and then the limiting stop 244 passes through the notch 2431, at this time, the rotating disc 237 rotates one circle, and is then limited by the limiting device from the new time.
Sixth, after one rotation of the rotating disc 237, the power disc 235 is pushed, and the unlocking rod 234 pushes the trigger block 2294, so that the limit tongue 229 is retracted, and the limit tongue 229 is separated from the fixed tongue 228.
Seventh, the driving rod 223 is pushed by the driving rod 226 under the pushing of the second spring 227, so that the driving rod 223 pushes the second push rod 216 through the transmission air channel 221, and the push rod 214 is pushed up through the second push rod 216, so that the protective cover 10 is lifted.
Further, when it is necessary to store energy in the torsion spring 316 on the driving shaft 311, the following manner may be adopted, and for this purpose, in this embodiment, the lateral movement device is an energy storage device. The specific manner is that, firstly, through the triggering device, the guiding fixing frame 323 moves upwards to enable the rotating chain 324 to be meshed with the driving gear 326, then the rotating post 325 is rotated, and then the rotating post 325 drives the chain 324 to rotate, so that the driving shaft 311 is driven to slide transversely, and when the driving shaft 311 is abutted against the tail end of the guiding sliding groove 321, the rotating post 325 is continuously rotated, the rotating shaft 311 can be driven to rotate, and therefore energy can be stored for the torsion spring 316. At this time, the driving gear 312 has been pulled out from one side of the driven gear 318.
In summary, the protection cover is automatically closed after the drawer 2 is drawn out from the case 1, so as to prevent the embryo in the drawer 2 from being affected by the outside air, and the protection cover is opened again after the drawer 2 is inserted into the case 1 for a period of time, so that the environment generating device in the case 1 can have enough time to draw the drawer 2 out of the case 1, and the outside air mixed into the case 1 is completely diluted.
