two opposite top beads are arranged in the rear swing arm support plate fixing block (104), and a necking is formed by the two top beads so as to fix the rear swing arm support plate (200).
6. The unmanned aerial vehicle ejector launcher emitter carriage of claim 4,
the opening device (400) comprises a rotating shaft (410) and at least one torsion spring (420) mounted on the rotating shaft (410);
one end of the rotating shaft (410) extends into the front fixed seat (310) to connect the front base and the front rotating part (312), and the other end of the rotating shaft (410) extends into the rear fixed seat (320) to connect the rear base (321) and the rear rotating part (322);
one side of the torsion spring (420) abuts against a transverse plate (102) of the front swing arm support plate (100) and is in a force accumulation state in the takeoff process of the unmanned aerial vehicle so as to drive the front swing arm support plate (100) to turn outwards.
7. The unmanned aerial vehicle ejector launcher launch vehicle of claim 1, wherein said launch vehicle further comprises a planar support frame (500), said planar support frame (500) comprising a front crash pad (510), a swing arm crash pad (520), and a locking bar arrangement (530);
the front anti-collision pad (510) is arranged at the front end of the plane support frame (500) and is used for preventing the launching trolley from directly impacting brake rubber arranged on the launching rack in the sliding process on the launching rack;
the swing arm anti-collision pads (520) are arranged on two sides of the plane support frame (500) and used for preventing the support body from being damaged due to collision in the process of turning outwards;
the locking rod device (530) is arranged at the rear part of the plane support frame (500), is clamped into a locking mechanism of the ejection frame when the launch vehicle is in a non-launch state to prevent the launch vehicle from being ejected, and is separated from the locking mechanism in the launch process of the launch vehicle.
8. A method of launching an unmanned aerial vehicle using the unmanned aerial vehicle launcher launching trolley of claim 1, comprising:
a locking bar means (530);
laying down a rear swing arm support plate (200) and enabling the rear swing arm support plate (200) to be clamped into the rear swing arm support plate fixing block (104);
clamping a front ejection shaft at the bottom of the unmanned aerial vehicle to a first notch (110) at the top of a front swing arm support plate (100);
the rear swing arm support plate (200) in a laid state is pulled up, and a rear ejection shaft at the bottom of the unmanned aerial vehicle is clamped to a second notch (210) of the rear swing arm support plate (200);
the bottom of the rear swing arm support plate (200) is clamped into a bottom groove of a rear base (321), so that the front swing arm support plate (100) and the rear swing arm support plate (200) are prevented from turning outwards;
the traction rubber of the ejection rack accumulates force, the lock rod device (530) is opened to release the launching trolley, and the launching trolley slides on the ejection rack rail until the front anti-collision pad (510) at the front end of the launching trolley impacts the brake rubber of the launching trolley and then stops sliding;
the unmanned aerial vehicle continues to slide under the action of inertia force, and a rear ejection shaft at the bottom of the unmanned aerial vehicle pulls forwards and opens the constraint of the rear swing arm support plate (200) in the rear fixed seat (320);
the opening device (400) drives the front swing arm support plate (100) and the rear swing arm support plate (200) to outwards turn around the installation shaft of the opening device (400), so that the unmanned aerial vehicle can take off smoothly.
