[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a visual teaching device for embedded development, which has the following beneficial effects:

[0019] 1. The visual teaching equipment for embedded development provides support and stability through the base. The support frame realizes the lifting and adjustment of the display table through the lifting plate, so as to adjust the display angle and height of the display screen. The design between the display screen and the cover plate makes the screen and the cover plate match in size, ensuring that the display screen is well protected when hidden. The stabilizing component ensures the stability of the equipment during use to avoid tilting or shaking due to vibration or external force. The hidden component hides the display screen safely when it is not in use, saving space and protecting the equipment. The extension component can adjust the length of the display screen according to needs to meet the needs of different teaching scenarios; based on multiple adjustable functions, the flexibility and stability of the equipment in the teaching process are improved. Through the adjustable lifting, hiding and extension functions, the diversity and flexibility in teaching are improved. The cooperation of the lifting plate and the extension component not only improves the operability of the equipment, but also meets different teaching needs and adapts to the requirements of different students and teaching environments. The stabilizing component ensures that the equipment is stable and reliable during use, reducing unnecessary failures caused by improper operation of the equipment. The hidden component allows the display screen to be safely stored when not in use, saving space, while protecting the equipment and extending its service life, effectively improving the practicality, durability and space utilization of the teaching equipment.

[0020] 2. The visual teaching device for embedded development, when using the device, by pulling the drive plate, the meshing drive teeth are driven to rotate through the drive plate, and the drive column can be driven to rotate synchronously, thereby driving the synchronous disk to deflect, and the guide groove provided on the synchronous disk can be rotated at the same time, thereby enabling the limit rod to drive the sliding plate to slide in the sliding sleeve, and in this process, the distance between the sliding plate and the sliding sleeve can be changed, so that the sliding plate can be extended from the inside to the outside of the base, and the guide rod can be separated from the trigger rod, and under the influence of gravity, the contact plate can be made to contact the ground first, and at the same time, the elastic force of the buffer spring can ensure that the contact plate is always in contact with the ground under the guidance of the guide rod, and at the same time, the bottom of the contact plate is made of rubber material, so that the contact plate can achieve a stable contact effect when contacting the ground of different materials, thereby ensuring that when the device is located in different environments, it can achieve a stable effect, enhance the overall stability of the device, ensure safety and comfort during use, and avoid device damage caused by shaking and collision.

[0021] 3. The visualization teaching equipment for embedded development, when using the equipment, firstly, by turning the driving handle, the deflection rod can be rotated, at this time, the rotating wheel is driven to rotate by the first synchronous wheel, and at the same time, the synchronous gear ring on the first synchronous rod can be driven to rotate synchronously, so that the lifting and lowering gear plate meshing with the synchronous gear ring can be synchronously moved on the support frame, and when the lifting and lowering gear plate moves, the lifting and lowering plate can be driven to move synchronously, and when the lifting and lowering plate moves, the bottom of the display screen can be rotated along the axis of the rotating seat, and at the same time, the rotating rods on both sides of the display screen can assist the display screen to deflect on the display table board, and the display screen can be unfolded at this time, which effectively ensures that the lifting and lowering process of the display screen is smooth and efficient, avoids vibration or damage of the equipment caused by improper operation, and makes the display screen convenient to hide or display when needed, thereby improving the flexibility of the equipment.

[0022] 4. This visual teaching device for embedded development ensures that the rotation angle of the deflection rod is accurately limited by cooperating with the ratchet ring and the limit teeth. The limit handle further controls the movement of the ratchet ring to ensure the accurate operation of hiding and displaying actions, improving the stability and safety of the device. The setting of the limit teeth and the limit handle effectively prevents excessive rotation and misoperation, further improving the convenience and accuracy of operation, and enhancing the functionality and user experience of the device.

[0023] 5. The visualization teaching device for embedded development, when the device is used, can realize the expansion function of the display screen according to different situations. First, by pulling and rotating the second rotating ring, the synchronous gear can be driven to rotate synchronously. While the synchronous gear rotates, the first movable plate and the second movable plate can be driven to move in opposite directions respectively. In this process, the first limit plate and the second limit plate can respectively drive the extended screen to move on one side of the display screen, thereby achieving the effect of screen expansion of the display screen. With the help of the limit spring, it is ensured that the extended screen is controlled and stable during the extension and retraction process. When the extended screen is extended to the corresponding position, it is only necessary to press the second rotating ring so that the positioning rod contacts the positioning groove, thereby ensuring the stability of the position of the second rotating ring, making the position of the expansion process stable and accurate, and at the same time ensuring that the extended screen can be flexibly adjusted according to teaching needs, and the adjustment process is accurate and reliable, thereby enhancing the flexibility and adaptability of the device.
