[0056] like Figures 1 to 5 As shown;

[0057] A landing gear, comprising a supporting bridge 11, a sliding column 12 is fixedly connected to the supporting bridge 11, a sliding sleeve 21 is slidably connected to the sliding column 12, a connecting bridge 22 is fixedly connected to the sliding sleeve 21, a rotating wheel 23 is rotatably connected to the supporting bridge 11, and a connecting piece is hinged between the supporting bridge 11 and the connecting bridge 22;

When the supporting bridge 11 and the sliding sleeve 21 approach each other, the pressing force increases continuously, and then as the supporting bridge 11 and the sliding sleeve 21 approach each other, the pressing force increases continuously, thereby achieving shock absorption when the supporting bridge 11 and the sliding sleeve 21 approach each other. When the supporting bridge 11 and the sliding sleeve 21 move away from each other, the pressure on the inclined protrusions 36 is gradually released. When the supporting bridge 11 and the sliding sleeve 21 move to the extreme distance away from each other, the vertical surfaces of the multiple inclined protrusions 36 on the two elastic connecting sleeves 33 are pressed against each other, and the extreme movement of the supporting bridge 11 and the sliding sleeve 21 is assisted to be limited, thereby assisting the spring in shock absorption, and the movement distance of the supporting bridge 11 and the sliding sleeve 21 can also be elastically limited.
