[0078] In this embodiment, before placing the tooth embryo, the locking plate 30 is first removed, and the tooth embryo can be fixed between the locking plate 30 and the baffle 29 by rotating the locking plate 30. When the support rod 24 is driven to rotate by the multifunctional driving component, the lifting plate 9 is in the initial position. At this time, the second spring 41 pushes the fixing block 40 to be inserted into the square hole of the rotating plate 17. The second rotating shaft 26 can be driven to rotate by the first motor 13, and the second sleeve 27 does not rotate with the second rotating shaft 26.

At this time, the locked support rods 24 make the driven gear 38 and the driving gear 33 relatively stationary, so that the driven gear 38 follows the driving gear 33 to rotate around the second rotating shaft 26, thereby driving the rotating plate 17 to rotate. During the rotation of the rotating plate 17, the second rotating shaft 26 follows As the lifting plate 9 slowly moves upward, the first spring 32 pushes the second sleeve 27 to slowly move upward, so that the second spring 41 presses the fixed block 40 to the bottom of the rotating plate 17. When the rotating plate 17 rotates 90 degrees, the fixed block 40 is pushed into the square hole by the second spring 41. At this time, the locking block 35 is separated from the connecting hole 36, so that the support rod 24 can rotate normally, thereby completing the work station switching. The matching setting of the fixed block 40 and the square hole on the rotating plate 17 can prevent the rotating plate 17 from rotating when the work station switching is not in progress.
