[0032] Working principle: When the staff needs to position the porcelain tooth, first place the porcelain tooth on the placement pad 3, then turn on the motor 401, and the output end of the motor 401 will use the screw rod 402 to make the two threaded sleeves 403 drive the two movable plates 404 to move to the opposite side, and then the two fixing frames 409 will drive the two clamping plates 405 to move relative to each other. When the two clamping plates 405 move to a certain position, the compensation pads 406 on their surfaces will contact the porcelain tooth, and the two sides of the porcelain tooth can be clamped and positioned. When the two movable plates 404 move relative to each other, the inclined parts of the two movable plates 404 will contact the extrusion plate 7. At this time, the extrusion plate 7 will be squeezed by the two movable plates 404 and move forward. The clamping plate 10 on the top of the extrusion plate 7 will conflict with the arc-shaped part of the porcelain tooth, thereby achieving a three-way extrusion effect to improve the positioning stability of the porcelain tooth.
