[0035] The installation groove 3 provides an installation space for the installation rod 4, so that the contact rod 5 can be inserted on the support rod 2.

[0036] In a preferred embodiment, as shown in Figure 8 and Figure 9 The protection assembly 6 comprises a rubber pad 61 sleeved on the outside lower side of the contact rod 5, two clamping pieces one 62 are fixedly connected to one side of the rubber pad 61, two clamping pieces two 63 are fixedly connected to the other side of the rubber pad 61, and the rubber pad 61 is clamped with the clamping pieces one 62.

[0038] When the unmanned aerial vehicle lands at a high speed or falls at a low altitude, the rubber pad 61 first contacts the ground, increasing the contact area of the contact rod 5 with the ground, so as to disperse the impact force to a larger area, avoiding excessive local stress on the contact rod 5 and causing damage to the contact rod 5 and the support rod 2, and when the ground is uneven or contains small stones and other impurities, the rubber pad 61 can avoid direct contact between the ground or small stones and other impurities and the contact rod 5, so that the contact rod 5 will not be rubbed and damaged, and the service life of the contact rod 5 will be longer.

[0039] In a preferred embodiment, as shown in Figure 3 、 4 , 5, 6, the limiting assembly 7 includes limiting slot one 72 respectively provided on both sides of the support rod 2 and two limiting slot two 73 provided on the upper side of the contact rod 5, the inner lower side of the limiting slot one 72 is hingedly connected with a limiting plate 71, the side of the limiting plate 71 close to the mounting rod 4 is fixedly connected with a connecting block 74, and the side of the mounting rod 4 close to the limiting plate 71 is provided with a connecting slot 75.

[0040] In this embodiment, when the contact rod 5 is not installed, the limiting plate 71 is placed in the limiting slot one 72, and when the contact rod 5 and the protection assembly 6 need to be installed, the protection assembly 6 is installed on the contact rod 5, and then the mounting rod 4 is inserted into the mounting slot 3, at this time the upper side of the contact rod 5 is in contact with the bottom end of the support rod 2, thereby the limiting plate 71 is buckled, so that the lower side of the limiting plate 71 in the vertical state can be rotated, and when the limiting plate 71 remains in the horizontal state, the limiting plate 71 can enter the inside of the limiting slot two 73, at this time the limiting plate 71 can clamp the clamping piece one 62 and the clamping piece two 63 at the plane between the limiting slot two 73 and the contact rod 5.

[0041] In a preferred embodiment, as shown in Figure 4 , the clamping assembly 8 includes a slot 81 provided in the inner bottom wall of the limiting slot two 73, the inner wall of the slot 81 is provided with a clamping slot 83 on both sides, the inside of the slot 81 is inserted with a plug rod 82, the inside of the plug rod 82 is provided with a placing slot 84 in parallel with the clamping slot 83, the inside of the clamping slot 83 is clamped with a clamping block 85, the side of the clamping block 85 away from the clamping slot 83 is fixedly connected with a pull rope 87, and the outside of the pull rope 87 is sleeved with an elastic piece 86.

[0046] In a preferred embodiment, as shown in Figure 4 , the connecting block 74 is rotatably connected in the inside of the contact rod 5, and the connecting block 74 is clamped in the inside of the connecting slot 75. When the contact rod 5 needs to be disassembled, the limiting plate 71 is rotated away from the limiting slot two 73, so that the limiting plate 71 is accommodated in the inside of the limiting slot one 72. At this time, the connecting block 74 is not in contact with the connecting slot 75, so that the mounting rod 4 is not limited, and the contact rod 5 can be disassembled and replaced. The limiting plate 71 not only limits the mounting rod 4, but also limits the protection assembly 6, achieving the effect of one thing serving multiple purposes.

[0047] In a preferred embodiment, as shown in Figure 4 , the top end of the plug rod 82 is fixedly connected to the bottom end of the limiting plate 71, the clamping block 85 is a “T”-shaped block structure, and is slidably connected in the inside of the placing slot 84.
