[0006] In the technical solution, since the first operation panel and the second operation panel both include mesh plates, the mesh plates can realize the installation and switching of multiple modules and multiple circuit functions of components. Since the upper ends of the first operation panel and the second operation panel are rotatably connected, the lower ends of the first operation panel and the second operation panel are both provided with insulating feet and foldable brackets, and the foldable brackets are provided with universal wheels. When needed, the first operation panel and the second operation panel can be unfolded, and the insulating feet can provide stable support. The universal wheels on the foldable brackets can be unfolded or folded according to the situation. When the foldable brackets are unfolded, the universal wheels are in contact with the ground, which is convenient for the overall movement of the device. When it is not necessary to move, the foldable brackets can lift the universal wheels, and the insulating feet can provide stable support for the device. Since the first operation panel and the second operation panel are respectively provided with foldable limiters on both sides of the entire device, the foldable limiters can provide a limiting effect when the first operation panel and the second operation panel are opened, the tilt angle of opening is selected according to actual needs during use to ensure that the overall stable triangular support structure is presented in the opened state.

[0007] This device adopts a foldable structure design of the first operation panel and the second operation panel. The device is small in size and adopts a folding design. When in use, the tilt angle of opening can be selected according to actual needs to meet different application scenarios. After use, the first operation panel and the second operation panel can be folded, which greatly saves space utilization. The device is equipped with universal wheels at the bottom to facilitate the movement and transportation of the device. The device has rich functions and adopts double-sided independent operation. The panel adopts a mesh plate structure. Both sides of the device can be independently wired and operated. The layout of components is flexible. According to the training needs of trainees, it can be freely combined and can meet the requirements of junior, intermediate and advanced electrician skills training at the same time.

When needed, the first operation panel and the second operation panel can be unfolded, and the insulating feet can provide stable support. The universal wheels on the foldable brackets can be unfolded or folded according to the situation. When the foldable brackets are unfolded, the universal wheels are in contact with the ground, which is convenient for the overall movement of the device. When it is not necessary to move, the foldable brackets can lift the universal wheels, and the insulating feet can provide stable support for the device. Since the first operation panel and the second operation panel are respectively provided with foldable limiters on both sides of the entire device, the foldable limiters can provide a limiting effect when the first operation panel and the second operation panel are opened, the tilt angle of opening is selected according to actual needs during use to ensure that the overall stable triangular support structure is presented in the opened state.
