[0031] Working principle: The staff places the circuit board that needs strength testing on the top of the strength testing workbench 1. At this time, the first spring 14 will push the sliding block 12, thereby driving the sliding block 12 to slide along the first sliding groove 11, and then driving the fixing plate 16 to fit the side wall of the circuit board to fix the circuit board. When the staff places the circuit board in the middle of the strength testing workbench 1, the top of the fixing seat 22 will first contact the bottom of the circuit board. When the staff continues to press, the second support shaft 21 will slide downward along the second sliding groove 2. At this time, the second spring 23 will push the fixing seat 22 to make the fixing seat 22 move smoothly into the second sliding groove 2. When the fixing seat 22 completely enters the second sliding groove 2, the fixing assembly will fix the fixing seat 22.

When the staff brings the circuit board into contact with the top of the fixing seat 22, the suction cup 4 will first contact with the pressing rod 43. At this time, the pressing rod 43 will push the exhaust plate 42 to move downward along the exhaust groove 41. When the circuit board contacts the top of the suction cup 4, a closed space will be formed between the circuit board and the suction cup 4. When the pressing rod 43 continues to push the exhaust plate 42 to move downward along the exhaust groove 41, the space between the circuit board and the suction cup 4 will become larger, but the total amount of gas between the circuit board and the suction cup 4 remains unchanged, thereby forming a negative pressure space between the circuit board and the suction cup 4.
