[0025] During use, the arc - shaped plates 19 at both ends of the support base 4 can facilitate the flow of air, avoiding an increase in the flight resistance of the support base 4 and the main body 1. The cross - section of the support rod 3 is U - shaped, and the two support rods 3 are arranged in a "V" shape to expand the support area of the two support rods 3. The support base 4 can slide inside the support frame 2, and the earthquake - resistant member is used to buffer the support base 4 against earthquakes, avoiding the main body 1 from being violently shaken or damaged by being knocked. The buffering member outside the support rod 3 can buffer the support rod 3, avoiding the support rod 3 directly contacting the ground and causing violent shaking to the main body 1.

[0026] In one embodiment, specifically, the seismic component includes a fixing frame 5 installed at the inner top of the support frame 2. A support plate 6 is installed at the bottom of the fixing frame 5. A notch 7 is formed at the top of the support seat 4. A plurality of limiting rods 8 arranged evenly penetrate through the inner side of the notch 7. A sliding block 9 is slidably connected to the outer side of the limiting rods 8 and inside the notch 7. A first spring 10 is sleeved on the outer side of the limiting rods 8. The seismic component further includes two groups of fixing rods 11 installed inside the support frame 2. A second spring 12 is sleeved on the outer side of the fixing rods 11. A shock absorber 13 is installed inside the support frame 2 and on one side of the fixing rods 11. A third spring 18 is sleeved on the outer side of the shock absorber 13. The fixing rods 11 penetrate through the support seat 4 and are slidably connected thereto. Two ends of the first spring 10 are fixedly connected to the notch 7 and the sliding block 9 respectively. The limiting rods 8 penetrate through the sliding block 9 and are slidably connected thereto. The sliding block 9 is hinged to the support plate 6. The top of the support plate 6 is hinged to the fixing frame 5.

[0027] Among them, the support plate 6 at the bottom of the fixing frame 5 can squeeze the sliding block 9. The plurality of limiting rods 8 can guide and limit the sliding block 9. The first spring 10 on the outer side of the limiting rods 8 can squeeze the sliding block 9. The plurality of fixing rods 11 can guide and limit the support seat 4. The second spring 12 on the outer side of the fixing rods 11 can press down the support seat 4. The third spring 18 on the outer side of the shock absorber 13 can support the shock absorber 13 to increase the compressive strength of the shock absorber 13 on the support seat 4.

The anti-abrasion pad 15 at the bottom of the buffer sleeve 14 can protect the buffer sleeve 14 and increase the abrasion resistance of the buffer sleeve 14. The elastic members 16 and the elastic sheets 17 can support the buffer sleeve 14 to increase the buffer compressive strength of the buffer sleeve 14.

[0030] The working principle of the present utility model:

[0031] First, when the main body 1 lands, the bottom of the support base 4 contacts the ground, and then the shock absorber 13 and the support plate 6 are squeezed and pushed. At this time, the support base 4 squeezes the first spring 10. At the same time, the support base 4 slides outside the fixed rod 11. At the same time, the support base 4 squeezes the shock absorber 13. Due to the mutual action of forces, the first spring 10 presses down on the support base 4. At the same time, the first spring 10 outside the limit rod 8 squeezes the sliding block 9. Then, the support plate 6 at the top of the sliding block 9 changes its angle at the bottom of the fixed frame 5. At the same time, multiple shock absorbers 13 absorb and dissipate the kinetic potential energy of the support base 4. At the same time, the anti-wear pad 15 at the bottom of the buffer sleeve 14 outside the support rod 3 contacts the ground. At this time, the elastic member 16 and the elastic sheet 17 support the buffer sleeve 14.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
