[0024] The adjustment component 9 includes a slide groove 901, which is provided on one side of the body 1, a slider 902 is slidably connected in the slide groove 901, a second fixed plate 904 is provided on the slider 902, a mobile frame 907 is fixedly connected to one side of the second fixed plate 904, a load-bearing plate 7 is fixedly connected to the top of the mobile frame 907, and a load-bearing column 8 is fixedly connected to the top of the load-bearing plate 7. The load-bearing column 8 is driven to move by adjusting the position of the second fixed plate 904, so that the spacing of the load-bearing columns 8 is changed, so as to facilitate the support of helicopters of different sizes.

[0025] The second fixing plate 904 has a connection hole 905 on its surface, the slider 902 has a mounting hole 903 on its surface, and the slider 902 is fixedly connected to the second fixing plate 904 by a second fixing bolt 906. The second fixing plate 904 and the slider 902 are fixed by the cooperation between the connection hole 905 and the mounting hole 903, and the sliding of the slider 902 drives the moving frame 907 to slide.

[0026] Among them, a connecting frame 908 is fixedly connected to one side of the machine body 1, a screw rod 909 is rotatably connected between the fixed frame 3 and the connecting frame 908, and a turntable 910 is fixedly connected to one end of the screw rod 909. The screw rod 909 is rotated by rotating the turntable 910, so that the mobile frame 907 slides along the slide groove 901, and the distance between the two groups of load-bearing columns 8 is adjusted.

[0027] The screw rod 909 is threadedly connected to the mobile frame 907, and the screw rod 909 is arranged at the center of one side of the fixed frame 3. The mobile frame 907 is driven to move by the rotation of the screw rod 909, and the load-bearing column 8 is moved by the movement of the mobile frame 907, thereby changing the spacing between the two groups of load-bearing columns 8, so as to adapt to different types of helicopters, thereby supporting and fixing the helicopter.
