[0002] As we all know, in the testing of electronic products, traditional fixtures are unstable and easy to loosen, affecting the test accuracy and efficiency. Therefore, fixtures are used to clamp and limit the electronic products. When the object to be tested is placed in the fixture, the locking components inside the fixture are automatically activated through a specific trigger mechanism. These locking components use springs, buckles and other structures to tightly fix the object to be tested to prevent it from moving or falling off during the test. After the test is completed, the lock can be released through the unlocking device to facilitate the removal of the object to be tested.

[0003] At present, a Chinese invention with publication number: CN113406485B discloses a chip test fixture and a chip test fixture combination, wherein the chip test fixture includes: an EVB board with a groove in the center; a group of test interfaces arranged on the EVB board; a data transmission interface arranged on the EVB board; and a group of power supply interfaces arranged on the EVB board. Compared with the traditional three-piece fixture, only one chip test fixture is needed to obtain the de-embedding file, which is more convenient and quick.
