[0022] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figure 1-Figure 4 An embodiment of the utility model is a 3D printed tooth model, comprising a tooth model 1, a rotating hole is opened on the top surface of the tooth model 1, and a rotating structure 2 is arranged inside the rotating hole, a mounting component 3 is fixed to the bottom surface of the rotating structure 2, and auxiliary structures 4 are axially symmetrically arranged on both sides of the mounting component 3.

[0024] The specific problem addressed by this specific embodiment is to solve the problem that the tooth model is generally installed in the gum model, and when it needs to be taken out for observation and use, the disassembly operation is relatively complicated, and after use, it needs to be firmly installed inside the gum model again, and the installation operation is not convenient enough. This solution has a low disassembly and assembly efficiency for the tooth model. The utility model uses the rotation of the screw rod 31 to make the moving plates 32 connected by threads on its surface approach each other, and squeeze the spring plate 33 to make it deform, squeeze and fix it inside the gum model, which has the effect of facilitating the disassembly and installation of the tooth model 1.

[0025] The mounting assembly 3 includes a screw rod 31 fixedly connected to the bottom surface of the rotating structure 2, and both ends of the screw rod 31 are axially symmetrically threadedly connected to a moving plate 32, and the side of the moving plate 32 is fixedly connected to a spring plate 33. In this specific embodiment, a threaded hole is opened in the middle position of the surface of the moving plate 32, and the inner diameter of the threaded hole matches the outer diameter of the screw rod 31. The rotating rod 22 is inserted into the octagonal block on the top surface of the connecting rod 21, and the screw block 23 is twisted to drive the lower connecting rod 21 to rotate through the rotating rod 22. The connecting rod 21 drives the screw rod 31 fixed on the bottom surface to rotate. The movable plates 32 with axially symmetrical threaded connection at both ends of the screw rod 31 will move closer to each other. When the movable plate 32 moves, it will squeeze the spring plate 33 fixed on the side to cause it to deform. The deformation of the spring plate 33 will squeeze and fix it in the hole opened on the surface of the gum model, and the installation operation of the tooth model 1 is completed. When disassembly is required, it is only necessary to rotate the screw rod 31 in the opposite direction, thereby achieving the purpose of convenient and quick disassembly and installation of the tooth model 1, and convenient for personnel to disassemble, display and store it.

[0026] In this specific embodiment, the auxiliary structure 4 includes a sleeve 41 flexibly connected to the side of the spring plate 33, and a spring 42 is fixed to the side of the sleeve 41, and a slide bar 43 is fixed to the side of the spring 42, the outer diameter of the slide bar 43 matches the inner diameter of the sleeve 41, and the slide bar 43 is slidably connected to the inside of the sleeve 41; the slide bar 43 is pinched to compress the spring 42 and slide into the inside of the sleeve 41, and then the installation component 3 is placed in the hole reserved on the surface of the gum model, and the spring 42 rebounds to drive the slide bar 43 fixed on the side to reset, and squeeze and fix it to the inside of the reserved hole, which prevents the screw rod 31 from idling inside the reserved hole due to the friction between the movable plate 32 and the screw rod 31.

[0027] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
