At this time, a surgical simulation operation can be performed. When the operation is completed, the user places the 3D model in the storage cabinet 15, and the servo motor 57 is started at this time. The servo motor 57 drives the rotating shaft 51 to rotate, and at the same time, the rotating shaft 51 drives the seventh sprocket 62 to rotate, and the seventh sprocket 62 drives the eighth sprocket 64 to rotate through the fourth chain 63, and the eighth sprocket 64 drives the third transmission shaft 59 to rotate, and the third transmission shaft 59 drives the third bevel gear 60 to rotate The third bevel gear 60 drives the fourth bevel gear 61 to rotate, and the fourth bevel gear 61 drives one of the two second screw rods 54 to rotate, and one of the two second screw rods 54 drives the ninth sprocket 65 to rotate, and the ninth sprocket 65 drives the tenth sprocket 52 to rotate through the fifth chain 66, and the tenth sprocket 52 drives the other second screw rod 54 of the two second screw rods 54 to rotate, and the two second screw rods 54 respectively drive the two third moving blocks 55 to move, and the two third moving blocks 55 drive the rolling door to move.

After disinfection is completed, the heating plate is started to generate heat. At the same time, the rotating shaft 40 drives the multiple fan blades to rotate, blowing the heat generated by the heating plate toward the 3D model, which facilitates drying the 3D model. When using it next time, the user can search the storage cabinet 15 for a 3D model with a matching height. If there is an existing 3D model that matches the current height, it can be taken out of the storage cabinet 15 and used directly, reducing resource waste.

The four clamping blocks are slidably installed on the workbench 4. When the four electric telescopic rods are started at the same time, the four electric telescopic rods respectively drive the four clamping blocks to move relative to each other. The four clamping blocks facilitate the clamping and fixing of the 3D model, thereby preventing the 3D model from falling under the workbench 4 during use.
