[0002] With the continuous advancement of science and technology, people have higher and higher requirements on the performance of electronic equipment and electronic devices, especially the requirements on test fixtures are becoming more and more stringent, which indirectly increases the difficulty of the fixture testing industry; in many test occasions, the number of plug-in test interfaces of the board under test is increasing. In recent years, with the continuous deepening of research, a set of fixtures that can meet the plug-in function test of all interfaces of the PCB board under test has a good development prospect.

[0003] When testing PCB with a rising fixture, more than two mechanical movements are required to achieve full plug-in of the test interfaces of the PCB board. However, not all fixtures can be operated in any order. When most fixtures are tested, when mechanical movement 1 achieves partial plug-in, all mechanical movements after mechanical movement 1 must be launched in the corresponding order after all the plug-ins of the PCB board under test are completed. Otherwise, the PCB board under test and the fixture will go bankrupt. This makes it inconvenient to achieve long-distance mechanical movement anti-foolproofing, and the current anti-foolproofing mechanism occupies a large space, is complex to operate, and is not convenient enough.
