When the printing correction block 252 is installed, the sealing slide 242 can slide in the inner cavity of the embedded installation cylinder 24 and compress the rubber block 241 at the same time. The rubber block 241 is deformed to buffer the force applied to the tooth by the printing correction block 252 to ensure the safety of the tooth. Through the cooperation of the internal support 245, the elastic member 246, the limiting ring 247 and the sealed bonding plate 248, when the sealing slide 242 slides toward the expansion block 23, the limiting ring 247 can stretch the elastic member 246 to a position away from the sealed bonding plate 248, so that the inner cavity of the one-way cavity 244 is unidirectionally exhausted, realizing the one-way buffering function, and avoiding the problem that the reset of the rubber block 241 will cause a large force on the tooth after the printing correction block 252 is installed.

[0022] As an implementation method in this embodiment, Figure 1 、 Figure 2 、 Figure 3 As shown, the movable sleeve 21 is movably connected to the outer wall of the elastic metal arch wire 1, and the top and bottom of the movable sleeve 21 are detachably connected to the positioning rivet 22. The end of the positioning rivet 22 is movably connected to the outer wall of the elastic metal arch wire 1. The right side of the movable sleeve 21 is fixedly connected to the expansion block 1 23, and the embedded installation cylinder 24 is fixedly installed on the right side of the expansion block 1 23. The left side of the rubber block 241 is fixedly connected to the right side of the expansion block 1 23. A socket 25 is movably inserted into the inner cavity of the embedded installation cylinder 24. The left side of the socket 25 is fixedly connected to the glue layer 251. The left side of the glue layer 251 is fixed to the right side of the sealing slide 242. Connection, the right side of the socket 25 is fixedly connected with a printed correction block 252. The user can slide the movable sleeve 21 on the outer wall of the elastic metal arch wire 1 to adjust the spacing of the printed correction block 252. After adjusting into place, tighten the positioning rivet 22 to complete the positioning of the printed correction block 252. The printed correction block 252 is produced by scanning the user's tooth shape and then using a 3D printer. After the production of the printed correction block 252 is completed, the socket 25 is plugged into the embedded installation cylinder 24. Through the design of the glue layer 251, the socket 25 is fixedly connected to the sealing slide 242, and the assembly of the printed correction block 252 is completed.

[0023] As an implementation method in this embodiment, Figure 1 、 Figure 4 As shown, the left side of the movable sleeve 21 is fixedly connected to the expansion block 26, and the left side of the expansion block 26 is fixedly installed with a connecting block 27. A strip groove 271 is provided on the side of the connecting block 27, and a circular groove 272 is provided on the inner wall of the strip groove 271.

When the plug-in strip 274 is plugged into the inside of the strip groove 271, the soft plastic card 273 will first be elastically deformed and hidden in the circular groove 272. After the plug-in strip 274 is plugged into place, the soft plastic card 273 will be reset and fixed to the inside of the fitting groove 275, thus completing the installation of the finishing block 276. Conversely, the finishing block 276 can be disassembled, which is convenient for users to replace the finishing block 276 and increase the aesthetics.

[0024] Working principle: First scan the shape of the user's teeth, and then use a 3D printer to produce the printed correction block 252. After the production of the printed correction block 252 is completed, the connector 25 is plugged into the embedded installation cylinder 24 to complete the assembly of the printed correction block 252, and then the elastic metal arch wire 1 is installed in the user's mouth, so that the printed correction block 252 fits the user's tooth surface, that is, the correction function is realized. When installing the printed correction block 252, the sealing slide 242 can slide in the inner cavity of the embedded installation cylinder 24, and at the same time compress the rubber block 241, causing the rubber block 241 to deform, thereby buffering the force applied by the printed correction block 252 to the tooth.
