With the cooperation of the fixing block 5, the main fastening layer 6 can change from an I-shape to a V-shape. When the adjusting assembly 8 is rotated, the secondary screw 17 in the adjusting assembly 8 can push the abutment block 19 to move with the cooperation of the base plate 9. The abutment block 19 can push the middle of the secondary fastening layer 7 to move synchronously, so that the secondary fastening layer 7 changes from a planar structure to an arc-shaped convex structure. Then, the precision complete denture body 16 is placed on the surface of the carrier plate 1, and the main screw 14 is rotated. The main screw 14 pushes the push plate 12 to move through the screwed main slider 13. The push plate 12 pushes the base plate 9 and the secondary fastening layer 7 to move synchronously through the fixing rod 10. Then, the main fastening layer 6 and the secondary fastening layer 7 can respectively abut against the two sides of the complete denture body 16. At the same time, the main fastening layer 6 and the secondary fastening layer 7 can respectively fit the arc surfaces on both sides of the complete denture body 16, thereby enhancing the stability of the clamp in positioning and holding the complete denture body 16. This can effectively prevent the complete denture body 16 from accidentally sliding during the positioning and clamping process, and can also effectively reduce the probability of the complete denture body 16 being squeezed and damaged. Furthermore, the clamp can be adjusted according to the changes in the size of the precision complete denture body 16, thereby enhancing the practicality of the positioning clamp and facilitating the subsequent processing of the precision complete denture.
