[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this embodiment can be combined with each other. The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 As shown, the purpose of this embodiment is to reduce the space occupied by the drone when not in use without affecting the stability when in use. In view of this, a drone rotor installation structure is provided, including a frame 1, and the four sides of the frame 1 are threadedly mounted with rotors 2, and the rotor 2 includes a first rod 21, and a second rod 22 is slidably inserted in the first rod 21. Among them, a groove 214 is opened through the inside of the first rod 21, and two slide grooves 211 are symmetrically opened on both sides of the inner wall of the groove 214. In order to prevent the second rod 22 from sliding off, the end of the slide groove 211 away from the frame 1 is in a closed state, and a first screw hole 213 is opened through the top of one side of the first rod 21, and a screw 5 is screwed in the first screw hole 213. Two symmetrical slide bars 221 are fixedly installed on both sides of the second rod 22. When the second rod 22 is slidably inserted in the groove 214, the slide bar 221 can be slidably inserted in the slide groove 211. A second screw hole 222 is provided at the top of the second rod 22. When the second rod 22 is fixed, the first screw hole 213 corresponds to the second screw hole 222, and the screw hole diameter is adapted to the screw 5. The end of the screw 5 is threaded through the first screw hole 213 and inserted into the second screw hole 222, thereby fixing the extension length of the second rod 22. Furthermore, a fixing member 23 is fixedly installed on the outer side of the first rod 21, and a support rod 24 is rotatably installed inside the bottom of the fixing member 23. The support rod 24 can drive the second rod 22 to slide inside the first rod 21, so that the end of the support rod 24 can be extended and retracted.

[0030] A slot 212 is provided through the bottom of the first rod body 21, a sawtooth bar 223 is fixedly installed on the bottom side of the second rod body 22, the fixing piece 23 is U-shaped, the first rod body 21 is passed through the inner side of the fixing piece 23, a first fixing rod 232 is fixedly installed on the inner side of the fixing piece 23, a gear 231 is rotatably installed in the middle of the first fixing rod 232, the top of the gear 231 is inserted into the slot 212 and meshed with the sawtooth bar 223; a half gear 241 is fixedly provided on the top of the support rod 24, a second fixing rod 242 is rotatably installed in the middle of the half gear 241, both ends of the second fixing rod 242 are fixedly connected to the two inner side walls of the fixing piece 23, and the top of the half gear 241 is meshed with the bottom of the gear 231.

[0031] In order to prevent the sawtooth bar 223 from rubbing against the inner wall of the groove 214, the diameter of the second rod body 22 is smaller than the diameter of the groove 214, and the top side portion of the gear 231 protrudes to the top outer side of the slot 212, the sawtooth bar 223 meshes with the gear 231, and the height of the second rod body 22 is supported by the slide groove 211 and the slide bar 221, so that it will not touch the bottom of the groove 214. When the support rod 24 is pulled outward, the half gear 241 will drive the gear 231 to rotate, and the gear 231 will drive the sawtooth bar 223 and the second rod body 22 to move; at the same time. Furthermore, the end of the second rod body 22 is threadedly installed with a drive plate 3, and a motor is installed in the drive plate 3, and the output shaft of the motor is connected to the blade 4. When the support rod 24 rotates to fit the bottom side of the first support rod 24, the second rod body 22 shrinks into the first rod body 21, and the end face of the first rod body 21 abuts against the side of the drive plate 3.

[0032] When the utility model is used, when not in use, the screw 5 is loosened, the support rod 24 is pulled, and the second rod body 22 is driven by the gear 231 to move toward the inside of the first rod body 21. When the support rod 24 is in contact with the bottom side of the first rod body 21, the second rod body 22 is retracted into the first rod body 21, and the end face of the first rod body 21 is in contact with the side face of the driving plate 3. When it is needed to be used, the support rod 24 is pulled downward, and the second rod body 22 is driven by the gear 231 to move toward the outside of the first rod body 21. When the support rod 24 is perpendicular to the ground, the second rod body 22 is fully extended and just blocked by one end of the slide slot 211, and finally tightened and fixed with the screw 5.
