In addition to the basic function of fixing various small electronic components, its more important function is to provide mutual connection between the above electronic components. Before using the PCB, it is necessary to check whether the surface welding of the PCB is defective to ensure that the PCB can be used normally. In order to ensure the fixing effect of the PCB during the inspection, the board body detection and adjustment structure will be used during the fixing.

[0004] However, this device still has some shortcomings. Since the PCB board has two sides, both sides need to be tested when it is tested. Since the clamping structure on the device cannot turn the PCB board over, when the back of the PCB board needs to be tested, the user needs to disassemble it and turn it over. After turning over, it needs to be clamped and fixed again before testing can be performed, which reduces the testing efficiency of the PCB board. Utility Model Content
