[0024] like Figure 1-4 As shown, the arms can be stored and accommodated through the storage seat 2, and the arm body 3 cooperates with the blades 4 to facilitate the flight operation of the flying car. When the arm body 3 needs to be folded, the dual-axis motor 5 is first operated, and the output shaft of the dual-axis motor 5 drives the threaded rod 6 to rotate. Since the threaded rod 6 and the sleeve plate 7 are in a threaded connection state, the threaded rod 6 drives the sleeve plate 7 to move to one side, and the sleeve plate 7 drives the connecting rod 8 to move to one side. One end of the connecting rod 8 drives the T-block 9 to move, so that the T-block 9 pulls the arm body 3 gradually toward the storage seat 2 until it enters the interior of the storage seat 2, thereby realizing the folding and storage of the arm body 3, and the folding is fully automated, which saves time and effort and improves convenience during use.

[0025] Example 2

[0026] Reference Figure 1 ,2 and 4, which are the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, a T-shaped slot 91 is opened on one side of the arm body 3 , and the T-shaped block 9 is located in the inner cavity of the T-shaped slot 91 and is slidably connected with the inner cavity of the T-shaped slot 91 .

[0028] The inner cavity of the storage seat 2 is movably connected to a limit rod 21 through a bearing, and one end of the limit rod 21 away from the storage seat 2 is fixedly connected to the arm body 3.

[0029] like Figure 1 , 2 As shown in FIG. 4 , the T-block 9 is located in the inner cavity of the T-slot 91, so that the T-block 9 can drive the arm body 3 to move when it moves, and the T-block 9 will slide along the inner cavity trajectory of the T-slot 91 during the movement, so as to achieve a limiting effect. The arm body 3 can be limited and supported by the limiting rod 21, and the arm body 3 can move axially with the limiting rod 21 when it moves.

[0030] Example 3

[0031] Reference Figure 3 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0032] In this embodiment, through slots 12 are provided on the front and back sides of the fixing seat 1 , and the connecting rod 8 passes through the inner cavity of the through slot 12 and is slidably connected to the inner cavity of the through slot 12 .

[0033] A limiting groove 11 is provided at the bottom of the inner cavity of the fixing seat 1 , and a limiting block 71 is fixedly connected to the bottom of the sleeve plate 7 . The limiting block 71 is located in the inner cavity of the limiting groove 11 and is slidably connected to the inner cavity of the limiting groove 11 .

The connecting rod 8 will move along the inner cavity trajectory of the through groove 12 during movement, thereby ensuring the stability of the connecting rod 8 during movement. At the same time, the sleeve plate 7 will drive the limit block 71 to slide along the inner cavity of the limit groove 11 during movement, thereby preventing the sleeve plate 7 from rotating during movement.

[0036] When in use, firstly, the dual-axis motor 5 is operated, and the output shaft of the dual-axis motor 5 will drive the threaded rod 6 to rotate forward. Since the threaded rod 6 and the sleeve plate 7 are in a threaded connection state, the threaded rod 6 will drive the sleeve plate 7 to move to one side, and the sleeve plate 7 will drive the connecting rod 8 to move to one side. One end of the connecting rod 8 will drive the T-block 9 to move, so that the T-block 9 pulls the arm body 3 gradually close to the storage seat 2 until it enters the interior of the storage seat 2, thereby realizing the folding and storage of the arm body 3. When the arm body 3 needs to be extended, When on display and in use, the output shaft of the dual-axis motor 5 drives the threaded rod 6 to rotate in the opposite direction, the threaded rod 6 will drive the sleeve plate 7 to move to one side, the sleeve plate 7 will drive the connecting rod 8 to move, and the connecting rod 8 drives the T-block 9 to move, and then the T-block 9 will push the arm body 3 to rotate, so that one end of the arm body 3 gradually separates from the interior of the storage seat 2 and extends to the outside, thereby realizing the extension operation of the arm body 3, facilitating the use of the arm body 3, and saving time and effort through full-process automated folding or extension, thereby improving convenience during use.
