The invention discloses a vertical rod sliding block device of a wind tunnel gust test vertical rod supporting system, which comprises a vertical rod main body, the middle part of the vertical rod main body is in sliding connection with a sliding block assembly, the sliding block assembly comprises back plates which are positioned on two sides of the vertical rod main body and are in sliding fit with the vertical rod main body, and the two back plates are fixedly connected through a screw rod; mounting seats are fixedly connected to the two back plates respectively, hydraulic brake mechanisms for limiting sliding of the back plates are mounted at the tops of the mounting seats, pitching flanges are rotatably connected to the middles of the mounting seats and fixedly connected with an airplane model, and adjusting parts for providing pitching rigidity of the airplane model are mounted on the back plates. The airplane model suspension device is low in supporting frequency and good in stability, after an airplan
