[

The height h2 of the left guard member 24 increases from the front end of the second fixing clip 25 to the opposite rear end thereof so that the height of the rear end portion coincides with the height of the locking protrusion 212, Two guide rods 242 and 243 and a bolt hole 244 are formed so that the bolt hole 244 is disposed between the rods 242 and 243 and the guide rods 242 and 243 and the bolt hole 244 The guide holes 217b and 218b and the fastening holes 219b are formed in the left side surface 214 of the main body 21 correspondingly so that the guide rods 242 and 243 are fitted in the guide holes 217b and 218b, (245) is fastened to the fastening hole (219b) of the main body (21) through the bolt hole (244).

The model base 81 of the mandibular tooth model 80 placed on the upper surface of the main body 21 is inserted into the main body 21 as shown in Fig. The guide rods 222, 223, 242, and 243 in the guide holes 217a, 218a, 217b, and 218b of the main body 21 by the protruded clearance t1 of FIG. The right guard member 22 and the left guard member 24 are adjusted to be brought into close contact with the side surfaces of the model base 81 of the mandibular tooth model 80 respectively and then the bolts 225 and 245 are tightened, So that the member 22 and the left guard member 24 are kept in close contact with each other.

Referring to FIG. 3 again, the up-and-down block 40 has two holes 41 and 42 through which the guide posts 30 are inserted up and down, and fastening holes 43 and 44 are formed in the side portions, And 42, respectively, and the compression bolts 45 and 46 are fastened to the fastening holes 43 and 44, respectively.

Thereby, after the height of the ascending / descending block 40 fitted to the guide post 30 is adjusted, the clamping bolts 45 and 46 are tightened to fix the ascending / descending block 40 to the guide post 30 do.

3 and 5, the angle regulating member 50 has a right side portion 52 and a left side portion 53 bent at both ends of the front portion 51 and formed in a diagonal shape, and the front portion 51 Down block 40 is disposed between the right side face portion 52 and the left side face portion 53 and the shaft pin 54 is disposed between the right side face portion 52 and the ascending / The front face portion 51 can be rotated up and down about the shaft pin 54 by being inserted into the left side face portion 53 of the right side face portion 52 through the through hole 40, A first groove 522 is formed in the upper and lower sides and a second groove 532 in the form of an arc is formed in the upper and lower portions at the rear end of the left side face 53 corresponding to the first groove 522, The long nut 55 is fitted in the bolt hole 48 of the ascending / descending block 40 and the pressing ring 555 attached to the end of the long nut 55 is caught around the first groove 522 , The long nut (532) through the second groove (532) The head portion 565 of the bolt 56 is caught around the second grooves 532. As a result,

With this arrangement, the bolt 56 is loosely fastened to the first nut 522 and the long nut 55 disposed in the second long groove 532, The placement angle is adjusted so that the upper tooth model 85 for the mandibular tooth model 80 determines the opening angle. At this time, the long nut 55 and the bolt 56 disposed in the first groove 522 and the second groove 532 relatively move from the lower end of the first groove 522 and the upper end of the second groove 532 to the upper end, . Thereafter, when the bolt 56 fastened to the long nut 55 is tightened, the compression ring 555 of the long nut 55 presses the right side face portion 52, and the head portion 565 of the bolt 56 moves to the left The right side face portion 52 and the left side face portion 53 are pressed and fixed to the both side faces of the ascending and descending block 40 by pressing the face portion 53 so that the protrusion of the upper dental model 85 against the lower dental model 80 State is maintained.

5 to 7, the connection structure of the angle regulating member 50 and the upper model supporting block 60 will be described.

The front portion 51 of the angle regulating member 50 and the main body 61 of the upper model supporting block 60 are connected by a connecting shaft 70. The connecting shaft 70 is connected to the first hexahedron 71, A first disk 73 and a spring 74 and a second disk 75 are fitted to the connecting shaft 70 and the first disk 73 and the second disk 75 The first hexahedron 71 is fitted into the rectangular groove 68 formed at the center of the rear end of the main body 61 of the upper model supporting block 60, The first hexahedron 71 is engaged with the engaging step 682 formed on the bottom surface and the cover 69 is mounted on the square groove 68 so as to cover the first hexahedron 71 and the second hexahedron 72 Is inserted into a square hole 515 formed in the front face portion 51 of the angle regulating member 50 and the first original plate 73 is brought into close contact with the inner face of the front face portion 51.

Thus, when the user pulls the main body 61 of the upper model supporting block 60 in the direction of the arrow 91 shown in FIG. 7 (b), the spring 74 is compressed, The second hexahedron 72 is pulled out from the square hole 515 of the front face portion 51 of the angle adjusting member 50 so that the user can see the upper face The upper model supporting block 60 may be rotated 180 degrees such that the lower mounting surface 611 of the main body 61 of the upper model supporting block 60 on which the tooth model 85 is disposed is raised to the upper side.
