When the limit value (corresponding to the rotation range in the above embodiment) of the grab clip 1 is checked, the grab clip 1 continuously transmits radar waves, and simultaneously can receive radar waves reflected by the wall body (corresponding to the fixing surface in the above embodiment) in real time, calculate the distance between the screen equipment and the wall body, stop moving after reaching the limit distance, and complete the check of the grab clip 1 after storing the limit distance of the grab clip 1 in the current direction and the maximum rotation angle of the center pillar. And each grabbing clip performs the above process, and the adaptation of the corresponding size and the rotation range of the screen-carrying equipment is completed, so that the maximum range value of the screen-carrying equipment, which allows rotation, is obtained.
