[0024] Referring to Figure 1 - Figure 4 As shown in the figure, in the embodiment: the size of plug 9 is matched with the size of insertion hole 11, the surface of plug 9 is matched with the inside of insertion hole 11, through the setting that the size of plug 9 is matched with the size of insertion hole 11, the stability and accuracy of plug 9 in the inside of insertion hole 11 are ensured, in addition, the sliding design of push block 8 makes plug 9 can be flexibly adjusted according to the movement state of protective cover 5, thereby realizing the accurate limiting of protective cover 5, this design not only improves the reliability of the device, but also reduces the maintenance cost caused by mechanical wear.

[0025] Referring to Figure 3 and Figure 4As shown, in the embodiment: the two sides of the adjusting groove 7 are provided with sliding grooves 12, and the two sides of the push block 8 are fixedly connected with sliding blocks 13, and the surface of the sliding block 13 is in sliding connection with the inside of the sliding groove 12. When the push block 8 is moved, the push block 8 drives the sliding block 13 to slide in the inside of the sliding groove 12. Through the above arrangement, when the push block 8 is moved by the worker, the sliding block 13 can be smoothly slid in the inside of the sliding groove 12 through the sliding cooperation between the sliding block 13 and the sliding groove 12.

[0026] Referring to Figure 4 and Figure 5 As shown, in the embodiment: the two sides of the mounting column 2 are fixedly connected with threaded rods 15, and the two sides of the rotating column 3 are provided with threaded grooves 14. The worker rotates the threaded rod 15 to insert the threaded rod 15 into the threaded groove 14. Through the above arrangement, the position of the rotating column 3 is fixed, and the rotation of the rotating column 3 in the inside of the mounting column 2 is avoided to cause unstable contact between the push block 8 and the arc-shaped block 6.

When the worker removes the contact between the arc-shaped block 6 and the plug block 9, the push block 8 moves to the outside of the adjusting groove 7 under the action of the rebound force of the force storage spring 18, and drives the plug block 9 to contact the limit between the plug hole 11, so as to facilitate the worker to disassemble the connecting rod 4 and the protective cover 5.

[0029] Working principle:

[0030] Step one:

[0031] The staff rotates the rotating column 3, which makes the rotating column 3 start to work and generate power or displacement, and the power or displacement further drives the push block 8 and the plug block 9 to move, laying a foundation for the subsequent contact and fixing operation.

[0032] Step two:

[0033] Under the drive of the rotating column 3, the push block 8 contacts the thicker end of the arc-shaped block 6, which makes the arc-shaped block 6 be pressed or pushed, so as to push the push block 8 to continue to move and drive the plug block 9 to move at the same time, and the series of actions make the plug block 9 gradually approach and finally insert into the plug hole 11.

[0034] Step three:

[0035] When the plug block 9 is successfully inserted into the plug hole 11, it realizes the fixing of the connecting rod 4, at this time, the protective cover 5 fixed on the surface of the connecting rod 4 plays its protective role and effectively protects the propeller of the unmanned aerial vehicle body 1.
