[0034] like Figure 5-Figure 7 As shown, the teaching seat IV5 is also provided with a clamping shaft assembly 8, and the clamping shaft assembly 8 includes an electric push rod 801, a motor 802, a driving rod 803, a clamping block 804 and a spring 805. An electric push rod 801 is installed on one side of the front of the teaching seat IV5, and the electric push rod 801 is located inside the rotating shaft 702. The push rod of the electric push rod 801 is installed with a motor 802, and the driving rod 803 is fixedly connected to the output shaft of the motor 802. A group of clamping grooves 704 are symmetrically provided on the side wall of each section of the rotating shaft 702, and the driving rod 803 is symmetrically provided with slots with the same number as the clamping grooves 704. The driving rod 803 is connected to the rotating shaft 702. Multiple groups of the slots are symmetrically and slidably installed with blocks 804, and springs 805 are provided between the blocks 804 and the driving rod 803. The blocks 804 are adapted to the corresponding slots on the rotating shaft 702, and the distances between the slots on each section of the rotating shaft 702 and the corresponding blocks 804 inside are different; the diameter of the driving rod 803 is slightly smaller than the inner diameter of the rotating shaft 702, and the blocks 804 are squeezed by the inner wall of the rotating shaft 702, compressing the spring 805 and being located in the slot 704 of the driving rod 803, and the left side of the blocks 804 close to the inner wall of the rotating shaft 702 corresponding to the slot 704 is an inclined surface.

[0035] The device is used to teach obstetrics and gynecology to pregnant women about mental health. Medical staff controls the servo motor 602. The output shaft of the servo motor 602 drives the gear block 603 to rotate. The rotating gear block 603 is engaged with the corresponding tooth plate 601. At this time, since the tooth plate 601 is in a fixed state, the gear block 603 will be pushed upward by the reaction when it is engaged with the tooth plate 601. At this time, the gear block 603 will drive the corresponding teaching seat II3, teaching seat III4 and teaching seat IV5 to rise from the teaching seat I2 in stages. When the teaching seat II3, teaching seat III4 and teaching seat IV5 When both are fully raised and opened, medical staff can post teaching content on teaching seat I2 and carry out corresponding teaching activities on teaching seats II3 and III4. When it is necessary to display the teaching roll 703 on teaching seat IV5, the electric push rod 801 is activated, and the electric push rod 801 pushes the motor 802 and the driving rod 803 to move synchronously through the push rod until a group of blocks 804 on the driving rod 803 are aligned with the slots 704 on the adjacent rotating shaft 702. The blocks 804 will pop outward under the action of the spring 805 and be stuck in the corresponding rotating shaft. The driving rod 803 is connected to the rotating shaft 702 of the section by the card slot 704. At this time, the motor 802 can be activated, and the output shaft of the motor 802 drives the driving rod 803 to rotate. The rotating driving rod 803 drives the rotating shaft 702 of the section clamped by the card block 804 to rotate, thereby realizing the lowering of the teaching roll 703 on the rotating shaft 702 of the section from the corresponding sleeve 701 for medical staff to demonstrate. Similarly, when it is necessary to lower the teaching roll 703 of other sections, the electric push rod 801 continues to push the driving rod 803. The rod 803 moves in the rotating shaft 702, so that the block 804 originally stuck in the slot 704 is elastically squeezed back into the driving rod 803 by the rotating shaft 702, until the next block 804 is aligned with the slot 704 on this section of the rotating shaft 702 again, and then the driving rod 803 can drive the section of the rotating shaft 702 to rotate, and finally put down the teaching roll 703 on this section of the rotating shaft 702. Therefore, the medical staff only needs to control the electric push rod 801 to automatically put down or retract the required teaching roll 703 from the sleeve 701, thereby improving the convenience of the device.

[0036] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 8 and Fig. 9As shown, the teaching seat III4 is provided with a light show component 9, and the light show component 9 includes a mounting plate 901, a fan blade circular plate 902, a rotating plate 903, a fan-shaped transparent plate 904, a gear shaft 905 and an electric gear 906.
