[0039] Reference Figure 1 , Figure 6 and Figure 7The utility model provides a dental medical teaching appliance, the joint mechanism includes joint board 20, first joint block 21, second joint block 22, limiting plate 23, pull rod 24, spring 25 and first fixed plate 26, the bottom of dental model 8 is fixed with joint board 20, joint board 20 is slidably connected with first connecting plate 7, one side of joint board 20 one end is fixed with first joint block 21, first joint block 21 is slidably connected with first connecting plate 7, the inner side of first connecting plate 7 near first joint block 21 one end is slidably connected with second joint block 22, the top and bottom of second joint block 22 are all fixed with limiting plate 23, two limiting plate 23 are slidably connected with first connecting plate 7, one end of second joint block 22 is fixed with pull rod 24, the outer side of pull rod 24 is sleeved with spring 25, and spring 25 is located in the inside of first connecting plate 7;

[0040] Through the design of the joint mechanism, different types of dental models 8 can be replaced at any time according to the teaching needs, so as to show more complex oral structures or pathological changes, and help students better understand and learn.

[0041] One end of the placement plate 5 is fixed with a controller 27, and the controller 27 is electrically connected with the electric push rod 3 and the first motor 14. The controller 27 is arranged to better control the electric push rod 3 and the first motor 14. The top of the base 1 is fixed with a power supply 28, and the power supply 28 is electrically connected with the electric push rod 3, the first motor 14 and the controller 27. The power supply 28 provides power for the electric push rod 3, the first motor 14 and the controller 27.

[0042] The use process of the dental medical teaching appliance is as follows: in order to enable more people to better observe the dental model 8, the first motor 14 is started by the controller 27, the output end of the first motor 14 drives the bidirectional threaded rod 15 to rotate, and since the bidirectional threaded rod 15 is threadedly connected with the first sliding plate 16 and the first sliding plate 16 is slidably connected with the base 1, the rotation of the bidirectional threaded rod 15 drives the first sliding plate 16 to move, the two first sliding plates 16 move towards each other, and since the first sliding plate 16 is rotationally connected with the second connecting plate 17 and the second connecting plate 17 is rotationally connected with the second sliding plate 18, the movement of the first sliding plate 16 drives the second sliding plate 18 to move downwards, so that the movable wheels 19 fixedly connected with the second sliding plate 18 move, the movable wheels 19 are in contact with the ground, thereby facilitating the overall movement of the teaching appliance.

[0043] The design of the moving mechanism enables the dental model 8 to be easily moved to the middle of the students, enabling the students to have the opportunity to observe, touch and discuss the dental model 8 at close range. Such interactivity helps to stimulate the learning interest and enthusiasm of the students and improves their participation.

[0044] In order to more conveniently observe the teeth on the tooth model 8, the worm 13 is rotated, since the worm 13 is in meshing connection with the worm wheel 12, the worm wheel 12 is fixedly connected with the transmission rod 10 and the transmission rod 10 is rotatably connected with the placement plate 5, so that the rotation of the worm 13 drives the transmission rod 10 to rotate, and since the transmission rod 10 is fixedly connected with the second bevel gear 11, the rotation of the transmission rod 10 drives the second bevel gear 11 to rotate, so that the first bevel gear 9 in meshing connection with the second bevel gear 11 also rotates, and since the first bevel gear 9 is fixedly connected with the connecting rod 6, the rotation of the first bevel gear 9 drives the connecting rod 6 to rotate, so that the first connecting plate 7 fixedly connected with the connecting rod 6 also rotates, and since the tooth model 8 is fixedly connected with the clamping plate 20 and the first connecting plate 7 is clamped with the clamping plate 20 through the clamping mechanism, the rotation of the first connecting plate 7 drives the tooth model 8 to rotate, so that the display angle of the tooth model 8 is changed;
