Fix the fixing plate 13 on the top of the fixing block 2 by bolts. Insert the fixing plate 13 into the fixing card slot 8. The fixing plate 13 presses the clamping block 12 to contract downward. When the fixing plate 13 is installed in place, under the action of the jacking spring 11, the connecting cross bar 9 is pushed to rise, and then the clamping block 12 moves upward to fix the fixing plate 13 in the fixing card slot 8. Place the chip in the positioning hole 6, cover the cover plate 4, so that the contacts at the bottom of the chip are in tight contact with the gold finger 15, which is convenient for detecting the chip and improves the detection efficiency.
