According to the sizes of the MAIN board and the IO board in advance, adjust the positions of each group of the first screws 401 and the second screws 406 on the main control board placing seat 2 and the IO board placing seat 306. After the first screws 401 and the second screws 406 are fixed to the main control board placing seat 2 and the IO board placing seat 306, the clamping sleeves 404 on their outsides can clamp and fix the MAIN board and the IO board. When placing the MAIN board and the IO board, the MAIN board and the IO board first engage with the clamping sleeves 404. At this time, under the support of the inner first spring 403 and the support rod 402, the clamping sleeves 404 tightly clamp the MAIN board and the IO board through the rebounding force, so as to realize the clamping and positioning function.

[0029] Please refer to Figures 4-6, a test device for detecting the MAIN board and the IO board. The reinforcement structure 5 includes a mounting base 501. A clamping groove 502 is formed inside the mounting base 501. A clamping plate 503 is clamped inside the clamping groove 502. A slot 507 is formed at the top of the clamping groove 502. An active block 504 is movably arranged inside the clamping plate 503. One end of the active block 504 is provided with a plug rod 506. The bottom end of the active block 504 is connected with a second spring 505. A threaded rod 508 is movably arranged on the right side of the active block 504.

A suction cup 512 is arranged at the bottom end of the moving block 510. The clamping plate 503 is clamped and connected with the clamping groove 502. The plug rod 506 is clamped and connected with the slot 507. An active groove matching the active block 504 and the second spring 505 is formed inside the clamping plate 503. The active block 504 is movably connected with the active groove through the second spring 505. The clamping plate 503 and the mounting base 501 are clamped and fixed through the clamping groove 502, the plug rod 506 and the slot 507. The support sleeve 509 is fixed at the bottom end of the clamping plate 503. The threaded rod 508 is movably connected with the clamping plate 503 through threads. A chute is formed inside the inner wall of the support sleeve 509. The moving block 510 is movably connected with the support sleeve 509 through the slider 511 and the chute. After placing the test device main body 1 on the tabletop, first hold down the active block 504. After the active block 504 is forced to move downward, it compresses the second spring 505 and drives the plug rod 506 to move downward, so that the plug rod 506 is received into the active groove. Then insert the clamping plate 503 into the inside of the mounting base 501. After being completely inserted, release the active block 504. Then the active block 504 moves upward and resets under the elastic support of the second spring 505, and thus is inserted into the slot 507 at the top of the clamping groove 502, so that the plug rod 506 is clamped and fixed with the slot 507, and the clamping plate 503 and the mounting base 501 are fixed. Finally, rotate the threaded rod 508. The threaded rod 508 rotates inside the clamping plate 503 through threads. When rotating, it presses down the moving block 510. When the moving block 510 moves downward, it compresses the suction cup 512 to expand, so that the suction cup 512 is tightly attached to the tabletop under force. Then the test device main body 1 is fastened to the tabletop through the reinforcement structure 5.

[0030] During use, after placing the main body 1 of the test device on the desktop, first hold down the movable block 504. After the movable block 504 is forced to move downward, it compresses the second spring 505 and drives the insertion rod 506 to move downward, so that the insertion rod 506 is retracted into the movable slot. Then, insert the engaging plate 503 into the inner side of the mounting seat 501. After it is completely inserted, release the movable block 504. Then, under the elastic support of the second spring 505, the movable block 504 moves upward and resets, and thus is inserted into the slot 507 at the top of the engaging slot 502, so that the insertion rod 506 is engaged and fixed with the slot 507, and the engaging plate 503 is fixed with the mounting seat 501. Finally, turn the threaded rod 508. The threaded rod 508 rotates inside the engaging plate 503 through the thread. When rotating, it presses down the moving block 510. When the moving block 510 moves downward, it compresses the suction cup 512 to expand. Thus, the suction cup 512 is tightly attached to the desktop under force, and the main body 1 of the test device is fastened to the desktop through the reinforcement structure 5. Adjust the positions of each set of first screws 401 and second screws 406 on the main control board placement seat 2 and the IO board placement seat 306 in advance according to the sizes of the MAIN board and the IO board. After the first screws 401 and second screws 406 are fixed to the main control board placement seat 2 and the IO board placement seat 306, the clamping sleeves 404 on their outer sides can clamp and fix the MAIN board and the IO board. When placing the MAIN board and the IO board, the MAIN board and the IO board are first engaged with the clamping sleeves 404. At this time, under the support of the first spring 403 and the support rod 402 inside, the clamping sleeves 404 tightly clamp the MAIN board and the IO board through the rebounding force, thus realizing the clamping and positioning function. The first handle 301 and the second handle 303 can be operated simultaneously. The first handle 301 drives the first needle board 302 to move downward through the connecting rod, and detects the MAIN board clamped and fixed on the main control board placement seat 2 through the probe. And the second handle 303 drives the second needle board 304 to move downward through the connecting rod, and detects the IO board clamped and fixed on the IO board placement seat 306 through the probe. The main board and the IO board can be tested simultaneously, which efficiently improves the test efficiency, reduces the working hour loss of the test personnel, and reduces the labor cost. It can also flexibly use one of the needle boards as a supporting test needle board for batch testing of the other needle board, and the operation is simple and convenient.
