Problems solved by technology
[0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject Boost drones below 50 kg, and drones weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport

Embodiment Construction
[0004] The trigger buckle of the catapult with a double joint and spring structure, the main structure includes a fixed box, an exciting shaft, a magnetic ring and a semicircular extrusion structure with a handle; in a fixed box, an exciting shaft is installed. Put two magnetic rings on the shaft, and the magnetic ring at the back is an extrusion magnetic ring, which is in contact with the semicircular extrusion structure with a handle. When the semicircular extrusion structure with a handle is moved more than one third; squeeze The pressure magnetic ring will push the excitation magnetic ring to slide quickly on the excitation shaft to achieve the purpose of excitation.

The invention relates to an ejector excitation fastener taking a permanent magnet ring as a contact structure. The ejector excitation fastener mainly structurally comprises a fixed box, an excitation shaft, magnet rings, a semicircular squeezing structure with a handle and the like; one excitation shaft is mounted in one fixed box, the excitation shaft is sleeved with the two magnet rings, the rear magnet ring is a squeezing magnet ring and is in contact with the semicircular squeezing structure with the handle, and when the semicircular squeezing structure with the handle is moved by more than one third, the squeezing magnet ring pushes the excitation magnet ring to quickly slide on the excitation shaft so as to achieve the purpose of excitation.
Description
Technical field [0001] The invention relates to an activation button of an ejector with a permanent magnet ring as a contact structure, in particular to an activation button with both a mechanical structure and a permanent magnet ejection structure. It belongs to the technical field of unmanned aerial vehicle catapults. Background technique [0002] In the field of ejection of small UAVs weighing more than 50 kg, there is no electromagnetic catapult suitable for such UAVs in China. According to reports, only the United States and Israel have similar UAV boosters. Domestically produced rubber band catapults can only eject UAVs under 50 kg can be boosted, and UAVs weighing more than 50 kg can only be boosted by solid explosive rockets, which is very dangerous and very difficult to carry and transport. Contents of the invention [0003] The trigger buckle of the catapult with a double joint and spring structure, the main structure includes a fixed box, an exciting shaft, a m...
