FIG. 10 is a schematic flow chart showing a method 900 for operating the dental clamping device according to an embodiment of the present invention. As shown, the method 900 of operating the dental clamping device includes a clamping member tightening step S12 and a replacement member replacing step S14, wherein the clamping member releasing step S12 is axially displaced and clamped relative to the pivoting rotating member 300 and the body 200. The member 400 is biased against the inclined slope 414 to abut the annular inclined surface 210, thereby changing the aperture D3. In detail, the clamping member tightening step S12 includes a clamping member relaxing step S122 and a clamping member clamping step S124, and the clamping member relaxing step S122 drives the clamping member relative to the pivoting rotating member 300 and the body 200. 400 is displaced along the positive X-axis direction. At this time, the aperture D3 becomes large, and the holder 400 can loosen the replacement member 830. In addition, the clamping member clamping step S124 drives the clamping member 400 to move in the negative X-axis direction relative to the pivoting rotating member 300 and the body 200. At this time, the aperture D3 becomes smaller, the holding member 400 can clamp the replacement member 830, and the replacement member 830 can detachably connect the abutment tooth assembly. The abutment tooth assembly includes abutment teeth and a plastic member, wherein the abutment teeth are screwed onto the replacement member 830, and the plastic member is tightly engaged with the abutment teeth, and the abutment teeth are located between the replacement member 830 and the plastic member. The plastic parts can be made of polymethylmethacrylate (PMMA) or polyetheretherketone (PEEK). The hardness of the plastic is softer than that of metal. It is very suitable for cutting or grinding by special tools made of metal. And quickly processed into the desired shape. The hardness of the tool is higher than that of the plastic part, and the tool can be in the form of a blade or a grinding drill. Further, the replacement part replacing step S14 separates the replacement seat assembly 800 from the rotating member 300, and takes out the replacement member 830 located in the replacement seat assembly 800 and replaces it with the holder 400. The sequence in which the foregoing steps are performed is the grip member relaxing step S122, the replacement member replacing step S14, and the gripping member clamping step S124. In other words, under the condition that the clamping member 400 does not grip the replacement member 830, when the user wants to install a replacement member 830, the replacement seat assembly 800 can be unscrewed through the hand-held rotating portion 810 to make the replacement seat assembly. The 800 is separated from the rotating member 300, and then the replacement member 830 required in the receiving groove 822 is taken out, and then the removed replacement member 830 is placed in the annular passage 4122 of the clamping member 400, and finally the rotating member 300 is rotated to reduce the aperture. D3, in turn, causes the holder 400 to stably grip the replacement member 830. In addition, a replacement member 830a has been gripped in the clamping member 400. Under the condition, when the user wants to install another replacement member 830b, the rotating member 300 can be rotated first to enlarge the aperture D3, and then the replacement member 830a on the clamping member 400 is taken out, and then the replacement seat is firstly transmitted through the hand-held rotating portion 810. After the assembly 800 is unscrewed, the replacement member 830b required in the accommodating groove 822 is taken out and exchanged with the replacement member 830a on the original clamping member 400. Finally, the removed replacement member 830b is placed on the clamping member 400 and the rotating member is rotated. The hole diameter D3 is reduced by 300, and the holder 400 is stably gripped by the replacement member 830b. Thereby, the user can freely replace the required abutment tooth assembly and the replacement members 830a, 830b by the removable dental clamping device 100. In addition, the replacement seat assembly 800 can be loaded with a plurality of different sizes of replacement members 830a, 830b in combination with the structure of the rotating member 300, and the rotating member 300 combined with the clamping member 400 can change the aperture D3 of the clamping member to clamp or relax different sizes. The replacement parts 830a, 830b solve the cumbersome and inconvenient use problem that the conventional clamping hand tool can only hold the single-sized abutment tooth assembly and replace the various specifications of the abutment tooth assembly.
