[0034] During testing, multiple products 7 are placed into the positioning slots 205 on the positioning plate 204. The output shaft of the first cylinder 601 pushes the moving seat 603 forward, which in turn moves the mounting cover 605 and the lower pressure plate 3 forward. Once the lower pressure plate 3 is directly above the positioning platform 201, the output shaft of the second cylinder 604 moves the mounting cover 605 and the lower pressure plate 3 downward. The inclined surface of the driving wedge-shaped pressure block 5 on the lower pressure plate 3 matches the guide inclined surface 20342 on the driving protrusion 20341. The first return spring 2036 compresses and pushes the guide clamping block 2033. When the guide clamping block 2033 is about to contact the product 7, the second return spring 2037 is forced to prevent the guide clamping block 2033 from advancing rapidly, thus buffering the impact force when the guide clamping block 2033 contacts the product 7. After contacting product 7, cylinder 2033 slowly advances and fixes product 7 on both sides, positioning product 7 horizontally. At the same time, pressure component 4 presses down to fix product 7 vertically. After pressure component 4 is fixed in the positioning slot 205, multiple products 7 are accurately positioned inside the positioning slot and testing begins. After the test is completed, cylinder 604 raises mounting cover 605 and lower cover 3. At this time, pressure component 4 and drive wedge-shaped pressure block 5 also rise together.
