At the same time, external force is applied to the connecting block, causing the connecting block to drive the threaded rod to rotate relative to the U-shaped frame. When the threaded rod moves to the designated direction, the first, second, and third damping plates are tightened. Then, the adjacent threaded rods are connected by a sleeve, which facilitates the splicing between adjacent control panel bodies and facilitates splicing work in different directions.

[0014] 2. This utility model, by setting a fixing component, allows the positioning bolt and the fourth damping plate to be tightened, causing the positioning bolt to move out of the positioning hole and the fourth damping plate to separate from the mounting frame. An external force is then applied to the movable plate, causing it to move the fixed plate left and right via the mounting frame. Simultaneously, an external force is applied to the L-shaped frame, which, under the action of the slider, moves the fixed plate forward and backward. When the fixed plate reaches the designated position, the positioning bolt and the fourth damping plate are tightened again, causing the positioning bolt to be threaded into the new positioning hole and the fourth damping plate to contact the mounting frame. This allows for adjustment of the fixed plate's position, facilitating the fixing of the control board body to different devices, expanding its applicability, and enhancing its practicality.
