The user checks the value of the display to make a qualified or unqualified judgment, so that the person can operate independently with both hands, which improves the convenience of operation. When the display blocks the eyes of the person and hinders walking, the display mounting plate is rotated along the connecting component to one side, and then turned back when in use. The stabilizing column is inserted into the stabilizing column groove along the opening, and a rubber pad is installed on the inner wall of the stabilizing column groove. The stabilizing column is fixed by friction, which solves the problem that the existing silicon carbide substrate surface flaw detector is to take the instrument with one hand and take the detection head with the other hand, and the single-handed operation is inconvenient. The detection head often needs to be put down for two-handed operation, and the position of the hand and the eye is not uniform, and the head often needs to be turned back and forth to check, resulting in inconvenience in use.

[0026] 2. The display mounting plate is connected to the adjustment frame through a connecting assembly, and the rotating column of the connecting assembly passes through the rotating groove and is rotatably connected to the rotating groove. The threaded column is threadedly fixed to the rotating column through the threaded groove, which has a traction and fixing effect on the rotating column. When the display mounting plate needs to be removed, the threaded column is rotated to remove it. After the rotating column loses traction, it slides along the rotating groove, thereby removing the display mounting plate. The hand passes through the anti-drop finger belt to grab the controller, and the detection effect is performed with one hand to take it with the other hand. The removed display mounting plate can also be tilted on the ground by relying on the tilt support seat, thereby realizing multi-mode operation and improving flexibility and convenience.
