It should be explained that when the first screw rod 21 rotates, the rotation of the first transmission nut 22 should be limited, so that the first transmission nut 22 cannot rotate with the first screw rod 21, so that the first screw rod 21 and the first transmission nut 22 rotate relatively, and the threaded connection relationship between the first screw rod 21 and the first transmission nut 22 enables the first transmission nut 22 to move linearly on the first screw rod 21. As for how to limit the rotation of the first transmission nut 22, a sliding track for the first sliding block to slide can be arranged on the denture carving machine 10, and the first transmission nut 22 is embedded in the first sliding block, so that the rotation of the first transmission nut 22 is limited by the first sliding block. It should be explained that the application does not limit the rotation limiting method or structure of the first transmission nut 22, and other limiting means can also be used in other embodiments.

[0043] Further, the output shaft of the driving part 13 of the third synchronous belt transmission mechanism 30 and the driving end of the screw block assembly of the third synchronous belt transmission mechanism 30 are both upward along the vertical direction.

[0044] Further, the synchronous belt wheel assembly of the third synchronous belt transmission mechanism 30 includes the second driving wheel 33, the second driven wheel 34 and the second synchronous belt 35 located in the same horizontal plane, the output shaft of the driving part 13 of the third synchronous belt transmission mechanism 30 is connected to the second driving wheel 33, the driving end of the screw block assembly of the third synchronous belt transmission mechanism 30 is connected to the second driven wheel 34, and the second driving wheel 33 and the second driven wheel 34 are drivingly connected through the second synchronous belt 35.

It should be explained that when the second screw rod 31 rotates, the rotation of the second transmission nut 32 should be limited, so that the second transmission nut 32 cannot rotate with the second screw rod 31, so that the second screw rod 31 and the second transmission nut 32 rotate relatively, and the threaded connection relationship between the second screw rod 31 and the second transmission nut 32 enables the second transmission nut 32 to move linearly on the second screw rod 31. As for how to limit the rotation of the second transmission nut 32, the sliding track for the second sliding block to slide can be arranged on the false tooth carving machine 10 or the first sliding block, and the second transmission nut 32 is embedded in the second sliding block, so that the rotation of the second transmission nut 32 is limited by the second sliding block.
