[0027] A method for using a testing device, using the above-mentioned AlGaNGaN HEMT device performance testing device, the method of use is as follows: S1. Preparation: Place the device to be tested in the middle of the test table 4, rotate the worm 901 according to the size of the device to be tested, adjust the position of the stabilizing component and the fixture 7 by adjusting the component to match the size of the device, and check the connection of the test mechanism 3; S2, protection: start the protection component, and the first baffle 502 and the second baffle 503 will move forward under the drive of the double-head motor 504. After moving to a certain position, the second baffle 503 is rotated and placed in front of the machine 1, and the protection component encloses and protects the detection platform 4; S3, positioning: start the electric push rod 6 to drive the clamp 7 to clamp the device to be detected, and the stabilizing component stably clamps and positions the device as the clamp 7 runs; S4. Test: Start the test organization 3 to test various data of the device to be tested, and the staff will record the data according to the test.

[0028] The technical solution provided by the present invention is that when testing a product, the product to be tested is placed on the testing table 4, and then the protective component is started. The operation of the protective component will seal the four sides of the product to be tested to achieve a protective effect, and then the expansion size of the adjustment fixture 7 is controlled by the adjustment component according to the size of the product. Then the electric push rod 6 will push the fixture 7 to position the product. During the positioning process, the stabilizing component will assist in positioning and improve the accuracy and stability of positioning. Finally, the testing mechanism 3 is started to test various performances of the product. Since the specific test equipment structure and test method of the test device are prior art well known to those skilled in the art, they will not be elaborated on here. The protective component is divided into two groups symmetrically arranged on both sides of the machine 1, and the double-headed motor 504 is started to drive the transmission rod 505 to rotate. Rod 505 drives gear 1 506 to rotate, gear 1 506 meshes with rack 1 507, gear 1 506 drives rack 1 507 to move and push the first baffle 502 to slide along the positioning slide groove 501, and the second baffle 503 slides accordingly under the action of the connecting shaft 508, and when the slide bar 509 slides to the complete rack 2 511, gear 2 510 meshes with rack 2 511, and then drives gear 2 510 and slide bar 509 to rotate, and synchronously drives the second baffle 503 to rotate, and the second baffles 503 on both sides rotate toward the middle of the machine 1, and the enclosure formed by the second baffle 503 and the first baffle 502 closes the periphery of the product to be tested, so as to achieve the effect of protection, avoid accidental injury caused by splashing objects due to collapse during the detection process, and improve the safety of detection; When the electric push rod 6 drives the clamp 7 to clamp and position the product, the push rod 807 will first abut the outer surface of the product. As the clamp 7 approaches, the push rod 807 will slide along the support 806 toward the inside of the U-shaped plate 801. During the sliding of the push rod 807, the limit rod 808 will slide in the limit groove 805 and push the push plate 804 to drive the shaft rod 802 to rotate, and at the same time, it will squeeze the spring 809. The rotation of the shaft rod 802 will drive the side to rotate toward the product. After the push rod 807 is completely retracted into the interior of the U-shaped plate 801, the side plate 803 will be clamped on the side of the product, and the clamp 7 will be used to position and clamp the product. Clamping the product in four directions can ensure that the product is located at the center of the test table 4. At the same time, it also improves the stability of clamping during product testing. When the product needs to be released, the electric push rod 6 drives the clamp 7 away from the product, the spring 809 rebounds and pushes the push rod 807 out of the U-shaped plate 801, and at the same time the limit rod 808 pushes the push plate 804 to drive the shaft rod 802 to rotate, and the side plate 803 moves away from the product, which is convenient for the next use. When clamping products of different sizes, the worm 901 is manually rotated, and the worm wheel 902 is driven to rotate during the rotation of the worm 901. Since the threaded sleeves 904 are fixed on both sides of the worm 901, and the threaded sleeves 904 are movably inserted in the middle of the vertical plate 903, the worm wheel 902 will drive the threaded sleeves 904 to rotate synchronously, and the threaded rod 905 will slide out of the threaded sleeves 904 as the threaded sleeves 904 rotate, and then the U-shaped plates 801 on both sides can be pushed away from or close to the clamp 7, thereby achieving the effect of adjusting the size and improving the applicability of the device.
