After the controller detection is completed, the controller can be quickly pushed out through the ejection mechanism 8, thereby improving the detection efficiency;

[0037] Then, a clamping plate 71 is pulled, and a slider 74 is driven by the clamping plate 71 to slide on the fixed rod 73. At this time, the spring 75 is compressed, and the slider 74 drives a rotating rod 79 to move.
