[0023] The guide rail 1 includes a slide groove 11, and a guide slide plate 12 is slidably arranged in the slide groove 11.

[0024] Specifically, when in use, the nose wheel of the carrier aircraft is clamped on the clamping block 20 on the fixing block 22, and then the nose wheel is placed on the smooth portion 15 on the placing block 13. At this time, the smooth portion 15 swings downward, and the elastic member 10 in the placing groove 100 is subjected to force. At the same time, the fixing block 22 swings slightly and is clamped on the nose wheel of the carrier aircraft. Then, the electromagnetic block 3 is started to push the slide plate 12 to slide in the slide groove 11 on the guide rail 1. After moving to the top point, when the carrier aircraft takes off, the elastic member 10 releases the force, and the smooth portion 15 is reset and swung upward, and the clamping block 20 is reset and detached from the nose wheel of the carrier aircraft.

[0025] In the above scheme, the slide plate 12 is moved by the slider on the slide plate 12, the nose wheel of the carrier aircraft is carried by the smooth portion 15 on the placement block 13, the elastic member 10 is placed by the placement groove 100 in the placement groove 100, and the nose wheel of the carrier aircraft is clamped by the fixing block 22 on the slide plate 12, and the carrier aircraft is driven to move on the deck by the clamped nose wheel.

[0026] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a notch 23 is formed on the fixing block 22 , a first piston rod 24 is rotatably disposed in the notch 23 , and a second piston rod 25 is slidably disposed in the first piston rod 24 .

[0029] Furthermore, it includes a smooth portion 15 , a first rod 17 is arranged on the second rod 18 , and the first rod 17 is arranged on the smooth portion 15 .

[0030] Specifically, when the nose wheel is placed on the smooth part 15 on the placement block 13, and then the smooth part 15 swings downward, the elastic member 10 is subjected to force, and at the same time drives the first rod 17 and the second rod 18 to move synchronously, and drives the block 20 to move through the connecting shaft 19, and at the same time drives the second piston rod 25 to move in the first piston rod 24. At the same time, the second piston rod 25 rotates on the block 20 through the rotating shaft 201 to fix the swing of the block 20.

[0035] Working principle: When in use, the nose wheel of the carrier aircraft is clamped on the clamping block 20 on the fixing block 22, and then the nose wheel is placed on the smooth part 15 on the placing block 13. At this time, the smooth part 15 swings downward, and the elastic member 10 in the placing groove 100 is subjected to force. When the nose wheel is placed on the smooth part 15 on the placing block 13, and then the smooth part 15 swings downward, the elastic member 10 is subjected to force, and at the same time drives the first rod 17 and the second rod 18 to move synchronously, and drives the clamping block 20 to move, and at the same time drives the second piston rod 25 to move in the first piston rod 24. At the same time, the second piston rod 25 rotates on the clamping block 20, fixes the swing of the clamping block 20, and clamps it on the nose wheel of the carrier aircraft, and then starts the electromagnetic block 3 to push the slide plate 12 to slide in the slide groove 11 on the guide rail 1. After moving to the top, when the carrier aircraft takes off, the elastic member 10 releases the force, and the smooth part 15 is reset and swung upward, and the clamping block 20 is reset and detached from the nose wheel of the carrier aircraft.
