[0002] PCB board will be tested before being put into use and after being used for a period of time to ensure that the performance of the PCB meets the requirements. There is also a PCB test box in the prior art. For example, a patent with application number 2015202368268 discloses a drawable PCB board test device, which comprises a test box and a support frame for placing the test box. The test box comprises an openable front door and a side door. The top of the support frame comprises a bottom plate for carrying the PCB board and front and rear side plates located at the front and rear ends of the bottom plate, respectively. The bottom of the test box is provided with an opening. The support frame can be pulled out along the opening direction of the front door and inserted into the opening at the bottom of the test box. The above-mentioned drawable PCB board test device can conveniently take and place the PCB board, and has high work efficiency. However, the structure only provides a simple platform. When the staff tests the PCB board, the support frame needs to be pushed out and then the PCB board is placed. After the PCB board is placed, the support frame needs to be pushed in again, which makes the PCB board testing work tedious.

The lifting plate is threadedly sleeved on the two screws. The driving mechanism is arranged on the top of the test box. The plurality of connecting mechanisms are arranged on the bottom of the lifting plate. The high-temperature-resistant test mechanism is arranged on the bottom of the lifting plate. The PCB board test device has the advantages of convenient aging test of the PCB board, convenient operation, and strong practicality. However, when the device is tested, the lifting plate needs to be moved by the driving mechanism, so that the PCB board can be electrically connected with the tester, which prolongs the time spent in the test preparation process.
