[0046] At the same time, the rotation of the rotating shaft 35 will cause the bevel gear six 48 to rotate. Through the meshing connection between the bevel gear six 48 and the bevel gear seven 50, the bevel gear seven 50 will rotate, and the bevel gear seven 50 will drive the rotating rod 49 to rotate. The rotating rod 49 will drive the threaded block 51 to rotate. Through the threaded connection between the threaded block 51 and the internal thread groove 14 and the sliding connection between the stabilizing block 53 and the stabilizing groove 54, the balancing leaf 52 will slide inside the accommodating groove 2 4, thereby moving the balancing leaf 52 to the inside of the accommodating groove 2 4. Then, the electric push rod 11 is started, which will cause the electric push rod 11 to drive the camera body 12 to move downward, thereby facilitating the camera body 12 to perform monitoring.

[0047] After the monitoring is completed, the drone body 1 needs to fall, thereby reversing the motor 33, and the motor 33 drives the worm 59 to rotate. Through the meshing connection between the worm 59 and the worm gear 34, the worm gear 34 is rotated, and the worm gear 34 drives the rotating shaft 35 to rotate. The rotating shaft 35 drives the bevel gear four 36 to rotate. Through the meshing connection between the bevel gear four 36 and the bevel gear eight 13, the bevel gear eight 13 is rotated, and then the transmission shaft 1 29 is rotated. Through the meshing connection between the bevel gear eight 13 and the bevel gear two 31, the bevel gear The second wheel 31 rotates, and then the bevel gear 2 31 will make the transmission shaft 2 30 rotate, and the transmission shaft 2 30 and the transmission shaft 1 29 will drive the bevel gear 3 32 to rotate. Through the meshing connection between the bevel gear 3 32 and the bevel gear 1 28, the bevel gear 1 28 will rotate, and the bevel gear 1 28 will drive the screw rod 24 to rotate. Through the threaded connection between the screw rod 24 and the internal thread block 23 and the sliding connection between the slider 22 and the slide rod 25, the internal thread block 23 will drive the height adjustment plate 15 to move downward, and the height adjustment plate 15 will drive The fixing cylinder 17, the buffer cylinder 18 and the support column 19 move downward synchronously, and the support column 19 will drive the connecting piece, the buffer piece, the mounting seat 20 and the moving wheel 21 to move downward synchronously, so that the moving wheel 21 can contact the ground, thereby facilitating the landing of the drone body 1. When the rotating shaft 35 rotates, the bevel gear 6 48 will rotate, and the meshing connection relationship between the bevel gear 6 48 and the bevel gear 7 50 will cause the bevel gear 7 50 to rotate, and the bevel gear 7 50 will drive the rotating rod 49 to rotate, and the rotating rod 49 will drive the threaded block 51 to rotate, and the threaded block 51 will rotate. The threaded connection between the block 51 and the internal thread groove 14, and the sliding connection between the stabilizing block 53 and the stabilizing groove 54, allow the balancing leaf 52 to slide inside the receiving groove 24, thereby moving the balancing leaf 52 to the outside of the drone body 1, thereby increasing the side wing size of the drone body 1 and improving the falling stability of the drone body 1. At the same time, when the drone body 1 tilts when landing, the balancing leaf 52 will contact the ground, thereby preventing the side wings of the drone body 1 from contacting the ground, thereby protecting the drone body 1.

[0048] When the moving wheel 21 contacts the ground, the moving wheel 21 will be acted upon by a force, and the moving wheel 21 will push the mounting seat 20 upward, and the mounting seat 20 will push the support column 19 upward, and then the support column 19 will push the buffer cylinder 18 upward, and the buffer groove 44 on the buffer cylinder 18 will slide on the outside of the buffer block 45, which will cause the spring 47 to generate elastic force, and then cooperate with the action of the energy-absorbing rod 46 to alleviate the shaking of the drone body 1, thereby improving the shock absorption performance of the drone body 1. At the same time, when the moving wheel 21 rotates, it will drive the mounting seat 20 to rotate, and the mounting seat 20 will drive the connecting rod 55 to rotate inside the slide rod 25, and then the rotating groove 58 will rotate on the outer wall of the rotating block 57, effectively providing the possibility for the rotation of the moving wheel 21.
