The device is fixed on the existing retaining wall through the angle steel, the structure of the retaining wall is fully utilized, and no additional supporting structure is needed; the gradient of the slope protection can be accurately controlled through the adjusting rod, the rigidity support of the adjusting rod and the slope protection formwork, and the included angle between the adjusting rod and the horizontal direction can be adjusted according to requirements to accurately control the slope gradient; the overall structure is simple and reliable, the device is convenient to install and disassemble, can be repeatedly used in different engineering projects, and the construction cost is reduced.

Embodiments of the present application provide an electronic device and a control method. The electronic device comprises a first shell, a second shell, a driving member, a traction member and a limiting assembly. The second shell is connected to the first shell and can slide relative to the first shell. The driving member is fixedly arranged on the first shell. The traction member is connected to the driving member. The limiting assembly is movably connected to the traction member. The driving member drives the limiting assembly to move through the traction member, so that the limiting assembly limits the first shell and the second shell when the second shell slides to a preset position relative to the first shell. The reliability of the electronic device can be improved.
