After launch, the elastic force of the unfolding spring 623 pushes the rotor head 620 and the rotor blades 621 to be immediately unfolded and locked, thereby ensuring that the flight unit can fly in time.

[0047] Working principle:

[0048] When storing, push the dust shield slide plate 627 to retract the positioning lock tongue 626, then rotate the rotor head 620 to fold the rotor head 620 and the rotor blades 621, and at the same time ensure that the folded rotor blades 621 are located inside the rotor storage slot 504, then start the electric telescopic cylinder 202, the electric telescopic cylinder 202 contracts to drive the sliding plate to slide down, the launching spring 203 is stretched to the longest and the elastic force is the lowest, then the flying part is slid into the gear guide 301, and the depression between the locking hook plate 305 is aligned with the protrusion on the surface of the casing 501. At this time, the folded rotor blades 621 are also inserted into the gap between the rotor storage slot 504 and the locking hook plate 305, and then the casing is pressed down. 501, at this time, the locking ring 506 is in contact with the lifting seat 405, and the anti-drop hook 407 is in an open state. As the housing 501 slides down, the extrusion block 408 slides through the clearance dropout slot 306 and drops out of the clearance dropout slot 306. At this time, the extrusion block 408 is pressed inwardly and closely adheres to the inner wall of the lock hook plate 305. The opened anti-dropout hook 407 closes inwardly and hooks into the locking slot 507. Then, as the lifting seat 405 slides to the end of the position, the lock ring 403 passes through the lower through hole 304, and then the electromagnetic lock 404 is started. The electromagnetic lock 404 extends the lock tongue to lock the lock ring 403, and at the same time the launch spring 203 contracts. At this time, the flight unit is stored and ready to be launched at any time;

[0049] During launch, the electric telescopic cylinder 202 is started, and the electric telescopic cylinder 202 extends to push the sliding plate upward, and the telescopic length of the electric telescopic cylinder 202 is adjusted according to demand, so as to control the contraction degree of the launching spring 203, and control the launching force of the launching spring 203, so as to adjust the launching length of the launching part, and then the angle adjustment motor 102 is started, and the angle adjustment motor 102 drives the angle adjustment shaft 103, and the angle adjustment shaft 103 drives the connecting ring 104 to rotate, so as to adjust the elevation angle of the launching tube 201. When the launch elevation angle parameters and the launch force parameters are adjusted, the electromagnetic lock 404 is started, and the lock tongue of the electromagnetic lock 404 is contracted, and the lock position of the lock ring 403 is released. The launching spring 203 extends to push the extension slider 402 upward, so that the locking seat 401 and the lifting seat 405 drive the flight part to push outward instantly. After reaching one side of the yielding and disengaging slot 306, the limit on the side of the squeezing block 408 is released, the disengaging spring 409 squeezes the anti-disengagement hook 407, the anti-disengagement hook 407 is pressed and opened, and the squeezing block 408 slides into the yielding and disengaging slot 306. At the same time, the anti-disengagement hook 407 releases the hooking of the locking collar 506 until the extending slider 402 slides to the end of the locking alignment guide slot 303, the locking seat 401 and the lifting seat 405 stop, and the flight unit continues to move and pops out due to its own inertia. After popping out, the limit of the rotor blade 621 is released, and the unfolding spring 623 pushes the rotor head 620 to rotate ninety degrees, and the rotor blade 621 is unfolded. At the same time, the positioning lock tongue 626 is snapped into the slot 622 to lock the unfolded rotor head 620, and then the rotor motor 601 is started to make the rotor blade 621 rotate, and the flight unit starts to fly by itself, thereby achieving launch.
