[0027] Among them, as shown in Figure 3 And Figure 4 , one end of each inductor one 10 is connected with lead-in wire 11, and these lead-in wires 11 are connected with controller 7 at the end, and the end of inductor two 12 is connected with controller 7 by a lead-in wire 11;Tooth is simulated by inductor one 10, and gum bed is simulated by fixed ring 9.

[0028] Among them, as shown in Figure 3 , both ends of upper and lower two groups of sensing mechanism are equipped with a group of rotating frames 13, and sleeve 14 is arranged on the rotating frame 13 at the two ends of upper sensing mechanism, and sleeve 14 is arranged in the rotating frame 13 at the two ends of lower sensing mechanism to form rotating connection;Two groups of sensing mechanism can rotate a certain angle around sleeve 14, and simulate mouth opening.

[0029] Among them, as shown inFigure 6 As shown, each set of fixing positions on the fixing ring 9 has a flange on its inner side, such as... Figure 7 As shown, the sensor 10 has a groove on its outer side, and the flange of the fixing ring 9 is inserted into the groove of the sensor 10 to form a releasable fixed connection; the sensor 10 is pulled out from the fixing position of the fixing ring 9 to simulate the tooth extraction process.

[0030] Among them, such as Figure 2 As shown, the controller 7 located on the upper side is fixedly connected to the cover 4 via two connecting rods 6, and the controller 7 located on the lower side is fixedly connected to the spherical shell 3 via two connecting rods 6; the sleeve 14 is fitted onto the sleeve rod 5 to form a rotatable connection; the spherical shell 3 and the cover 4 shield the sensing mechanism to simulate the dark environment inside the oral cavity during tooth extraction; by moving the cover 4, the upper and lower sets of sensing mechanisms can be separated from each other to simulate the opening of the oral cavity.

[0032] The specific usage and function of this embodiment are as follows:

Sensor 10 simulates teeth, and the fixing ring 9 simulates the jawbone; the two sets of sensing mechanisms represent the upper and lower jaws respectively. Sensor 10 is pulled out of its fixed position from the fixing ring 9, simulating a tooth extraction process. The guide wire 11 is of sufficient length to not hinder the removal of sensor 10 from the fixing ring 9. Sensor 10 is then grasped with tweezers and pulled outwards. Under normal circumstances, only the sensor 10 being pulled receives significant pressure, while the other sensors 10 receive less pressure. The two nearest sensors 10 may receive relatively small pressure. If other sensors 10 also receive large pressure, it means that other teeth were mistakenly extracted during the extraction process, and the simulation is unqualified. If sensor 12 receives large pressure, it means that the tweezers poked the gum during the extraction process, and the simulation is also unqualified. Regardless of which unqualified situation occurs, the signal will be transmitted to the controller 7 through the input line 11. The controller 7 controls the buzzer 16 to sound intermittently through the output line 15, and the frequency of the sound emitted by the buzzer 16 is different in the two unqualified situations.
