A support frame 4 and a surveying and mapping device 5 are bolted to the belly of the unmanned aerial vehicle body 1, and the surveying and mapping device 5 is located in the support frame 4.

[0033] With reference to Figure 2 The two ends of the connecting block 2 are detachably connected to adjacent arms 11. It can be understood that the four-rotor unmanned aerial vehicle has two connecting blocks 2, and the six-rotor unmanned aerial vehicle has three connecting blocks 2. The detachable connection between the connecting block 2 and the arm 11 can be bolted connection, buckle connection, or ribbon binding, etc. The connecting block 2 of the application adopts the quick disassembly and assembly mode of buckle connection, and the connecting block 2 can be made by 3D printing.

[0034] With reference to Figure 2 Each arm 11 corresponds to a universal shaping pipe 3, and the universal shaping pipe 3 is threadedly connected to the connecting block 2. The connecting block 2 is provided with a plurality of threaded holes 21 along the length direction of the connecting block 2, and the threaded holes 21 are used for threadedly connecting the universal shaping pipe 3. The end of the universal shaping pipe 3 away from the connecting block 2 is threadedly connected with a pointed end 6. The universal shaping pipe 3 is used for supporting the unmanned aerial vehicle body 1 away from the ground, and the pointed end 6 is used for inserting into the ground.

[0035] With reference to Figure 2 It is worth noting that the structure of the universal shaping pipe 3 is related to the weight of the unmanned aerial vehicle body 1. When the unmanned aerial vehicle body 1 is a small or medium-sized unmanned aerial vehicle, the universal shaping pipe 3 can be a plastic universal bamboo joint pipe, or a metal universal pipe, etc. which is light in weight and has certain flexibility and supporting force. When the unmanned aerial vehicle body 1 is a large unmanned aerial vehicle, the structure of the universal shaping pipe 3 comprises a ball-type holder and an extension pipe. The ball-type holder is threadedly connected to the connecting block 2, and the extension pipe is composed of a plurality of joint pipes which are threadedly connected to each other, and the extension pipe is threadedly connected to the ball-type holder. The purpose of such design is that the pressure on the universal shaping pipe 3 is different due to different weights. According to the weight of the unmanned aerial vehicle body 1, the appropriate universal shaping pipe 3 is selected, a plurality of universal shaping pipes 3 are used to support the unmanned aerial vehicle body 1, and the effect of stable and safe landing on different terrains is achieved.

[0036] With reference to Figure 3 and Figure 4, the connecting block 2 is provided with a storage groove 22 and a placing groove 23, a plurality of extension blocks 7 are placed in the storage groove 22 of the connecting block 2, and the two ends of the extension block 7 are respectively connected with the connecting block 2 and the universal shaping pipe 3 through threads. The two ends of the extension block 7 are respectively provided with an inner thread and an outer thread, the inner thread is engaged with the outer thread, and the universal shaping pipe 3 at the required position can be extended alone or in combination by using the extension block 7.
