Description

Technical Field

[0001] The utility model relates to the technical field of denture carving, in particular to a fixture for denture carving. Background Art

[0002] Dentures are what people often call "false teeth", just like "false legs" and "false limbs" are called "artificial limbs". "Dentures" means teeth that fulfill "duties" for humans. In medicine, it is a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into removable and fixed. Fixed dentures cannot be removed and put on by the patient himself, while removable dentures can be easily removed and put on by the patient.

[0003] Dentures are made by carving blanks. When carving with an engraving machine, the blank needs to be fixed. The device used to fix the blank is a clamp. Usually, the clamp used to fix the blank includes a fixed shaft and a clamping part connected to the fixed shaft. The fixed shaft and the main shaft of the machine tool are fixedly connected together. The clamping part includes a lower clamping plate fixedly connected to the fixed shaft and an upper clamping plate screwed to the lower clamping plate by bolts. During operation, the denture is clamped between the upper clamping plate and the lower clamping plate. However, the bolt fixing of the clamp in the prior art is cumbersome, and it is not convenient to rotate its position after clamping. Therefore, there is an urgent need for a clamp for denture carving to overcome the above defects. Utility Model Content
