The invention discloses a fixing mechanism, which is characterized in that a mounting seat is used for fixing a circuit board to be tested, and the mounting seat can be fixed with a vibration mechanism; the first base and the second base are arranged on the mounting seat, and the first base and the second base can be fixed with the vibrating mechanism; when the mounting seat and the vibration mechanism are fixed, the circuit board is in a first posture; when the first base and the vibration mechanism are fixed, the circuit board is in a second posture; and when the second base and the vibration mechanism are fixed, the circuit board is in a third posture. Compared with the traditional means, the device can complete the vibration test of the circuit board in different directions without re-installing the circuit board, thereby shortening the preparation period in the earlier stage of the test, and improving the installation efficiency of the test sample; the integrated structure is adopted, the structure is si
