The invention belongs to the technical field of airplane structural strength tests, and particularly relates to a wedge-shaped support height adjusting device which comprises a lower cushion block, an upper cushion block and an adjusting device body located between the lower cushion block and the upper cushion block, and the adjusting device body comprises an upper sliding block, a lower sliding block and a lead screw. The upper sliding block is provided with a first upper end face and a first lower end face, the lower sliding block is provided with a second upper end face and a second lower end face, the lower sliding block is provided with a lead screw, the axis of the lead screw is parallel to the second upper end face, and the second upper end face is provided with a sliding groove in the circumferential direction of the lead screw. The first lower end face is in lap joint with the second upper end face in an attached mode, the first lower end face is provided with a protruding block inserted into the sliding groove, and the protruding block is provided with an inner threaded hole in threaded connection with the lead screw. The first lower end face and the lower cushion block form an acute included angle relative to the movement direction of the upper cushion block; the lower cushion block is fixedly connected with the lower sliding block, the upper cushion block is in lap joint with the surface of the upper sliding block, the bearing capacity of the device is high, and long-time bearing of bolts is avoided through wedge-shaped supports; the wedge-shaped sliding block and the lead screw can be adjusted in a micro-distance mode, the adjusted device can be fixed through the bolt assembly, and the device is more stable.
