A method for installing an auxiliary installation mechanism for a flight data collector, based on the auxiliary installation mechanism for a flight data collector according to any one of claims 1 to 8, characterized in that: The following steps are involved: S1: Align the anti-drop hook (22) of the U-shaped connecting bracket (2) with the outside of the mounting frame (1), rotate the support rod (25) to lock it with the supporting beam (6), and adjust the hexagonal round head bolt (23) to fix it in the second threaded hole in the middle of the supporting beam (6); S2: Push the U-shaped connecting bracket (2) along the outside of the mounting frame (1) until the hooks (22) of the first fixing rod (4) and the second fixing rod (5) are hooked into the inside of the mounting frame (1), and stop pushing when the protective pad (20) contacts the front panel of the flight data collector (3); S3: Rotate the support rod (25) to the locking position, drive the support rods (25) of the left-turn block (10) and the right-turn block (11) to compress the spring (15) in the second fixing hole (13), insert the support rods (25) of the left-turn block (10) and the right-turn block (11) into the first threaded holes at both ends of the support beam (6), and lock and fix them with nuts (24); S4: Turn the handle (18) to drive the runner (9) to rotate, and the hexagonal round head bolt (23) and the hexagonal hole in the runner (9) are matched to prevent slipping, so as to push the movable pressure plate (8) to move linearly, and the movable pressure plate (8) applies pressure to the flight data collector (3) through the protective pad (20); S5: Continue to rotate the handle (18) until the end surface of the hook (22) is tightly fitted with the mounting frame (1), and the tail connector of the flight data collector (3) is fully connected with the connector of the mounting frame (1).
