During testing, the displacement mechanism 2 can drive the detection component 4 to move, achieving multi-point movement along the X, Y, and Z axes. During testing, it is only necessary to monitor the change in current to determine whether the brake shoe is flat. Specifically, the spring 47 pushes the slider 44 and the detection rod to contact the brake shoe. If the brake shoe bends, the detection rod 45 at the corresponding position will move, causing the slider 46 to slide and change the magnitude of the current, making it relatively easy to detect whether it is bent.
