[0023] In this embodiment, when the PCB board needs to be tested, it is first necessary to determine the length of the PCB board, and then adjust the clamping position of the PCB board according to the test range that the test equipment can test. First, during the use of the device, the sliding locker 202 needs to slide on the outer surface of the concave block 208 to drive the connecting block 203, the mounting plate 204, and the support plate 205 to move. During the displacement process, the fitting block 206 will also be driven to move to the appropriate position. After the movement is completed, the sliding locker 202 is locked.
