[0031] The first connecting plate 100, the second connecting plate 200, and the third connecting plate 300 are stacked sequentially from top to bottom, with a gap between the first connecting plate 100 and the second connecting plate 200, and a gap between the second connecting plate 200 and the third connecting plate 300; such that the flight controller (not shown) is located on a side of the first connecting plate 100 away from the second connecting plate 200;

[0035] The third connecting plate 300 includes a third body 310 and a third body extension portion 320 and a third body bending portion 330 integrally formed with the third body 310 .

[0039] The first connecting plate 100 includes a first body 110 and a first body extension portion 120 and a first body bending portion 130 integrally formed with the first body 110 . The first body bending portion 130 is located on a side of the first body extension portion 120 away from the first body 110 .

[0040] The first body extension portion 120 is flush with the first body 110 , and an included angle (a preset angle) is formed between the first body bending portion 130 and the first body 110 .

[0041] Among them, the shock-absorbing ball 400 is provided with a first hemispherical portion 410 and a first contraction portion 420 and a first expansion portion 430 integrally formed with the first hemispherical portion 410. The shock-absorbing ball 400 is also provided with a second hemispherical portion 440 and a second contraction portion 450 and a second expansion portion 460 integrally formed with the second hemispherical portion 440.

[0044] Among them, the first connecting plate 100, the second connecting plate 200 and the third connecting plate 300 are all made of elastic material; so that when the shock-absorbing ball 400 transmits external force, each bending part produces more obvious deformation, which helps to better dissipate the external force.

[0045] Example 2.
