As shown in fig. 1-2, a pneumatic catapult is hung at the front end of a gun barrel 100 and arranged along the front and back of the gun barrel 100, and comprises a firing device, wherein the firing device comprises an air storage cabin 1, the rear part of the air storage cabin 1 is communicated with an air guide cabin 2 through an air guide port 10, the rear part of the air guide cabin 2 is communicated with an air outlet channel 3 arranged up and down through an air outlet 20, and the rear part of the air outlet channel 3 is communicated with a firing cabin 4 through a driving port 30.

The air guide cabin 2 is internally provided with a movable sealing head 21, the movable sealing head 21 can move back and forth in the air guide cabin 2, the front side of the movable sealing head 21 is fixedly provided with a push assisting rod 211 which is arranged back and forth, the rear side of the movable sealing head 21 is fixedly provided with a push-out rod 212 which is arranged back and forth, the push assisting rod 211 is sleeved with a push assisting spring 2111, one end of the push assisting spring 2111 abuts against the air guide opening 10, the other end of the push assisting rod abuts against the front side surface of the movable sealing head 21 to enable the movable sealing head 21 to seal the air outlet 20, and the diameter of the push; the push-out rod 212 passes through the air outlet channel 3 and the driving port 30 to enter the interior of the firing chamber 4, and has a diameter smaller than that of the air outlet 20 and the same as that of the driving port 30.

The inside of the firing cabin 4 comprises a rear fixed block 41 and a front push-out block 42, the fixed block 41 is connected with the push-out block 42 through a telescopic spring 43, the push-out block 42 can move back and forth in the firing cabin 4, an excitation block 421 is fixed at the bottom of the push-out block 42, an excitation groove 420 for accommodating the motion of the excitation block 421 is formed at the bottom of the firing cabin 4, when the push-out block 42 moves to be close to the fixed block 41, the telescopic spring 43 is in a compressed state, and the excitation block 421 is abutted by a trigger mechanism 5.

Still including throwing device and throwing pipe 7, throw the device and fix in the percussion device top, including the bore pole 6 that sets up from beginning to end, the central authorities of bore pole 6 front portion are hollowed and are formed air push pipeline 60, air inlet 601 has been seted up to air push pipeline 60's lower part, air inlet 601 is the same and the area equals with gas outlet channel 3's shape, the below of bore pole 6 is fixed with the boosting piece 61, the upper portion of pushing piece 42 is fixed with the removal arch 422 that is located boosting piece 61 rear, percussion cabin 4 top is seted up and is held boosting piece 61 and removal arch 422 seesaw's boosting track hole 423. The projecting tube 7 is sleeved outside the chamber rod 6, the outer wall of the projecting tube 7 is communicated with a bullet inlet 70, and a gun hanging device 8 is fixed above the gun barrel 100.

The catapult 1000 injects gas into the gas storage tank 1 through the high pressure gas tank for storage before use, and since the gas guide port 10 is provided between the gas storage tank 1 and the gas guide tank 2 and the diameter of the push-aid rod 211 is smaller than the diameter of the gas guide port 10, the gas storage tank 1 and the gas guide tank 2 are filled with the initial gas. In use the ejector 1000 is hung from the barrel 100 and the bore 6 is slid rearwardly so that ammunition enters the barrel 7 from the feed port 70, in front of the bore 6. When the bore rod 6 slides backwards, the boosting block 61 slides backwards along with the bore rod and pushes the rear moving protrusion 422 to move backwards, the moving protrusion 422 is fixed on the pushing block 42, so that the pushing block 42 contacts with the fixed block 41 backwards, the extension spring 43 between the pushing block and the fixed block is compressed, and the excitation block 421 below the pushing block 42 is propped by the trigger mechanism 5, so that the whole system is fixed.

When the ejector 1000 is fired, the trigger mechanism 5 is pulled to ensure that the trigger mechanism no longer supports against the excitation block 421, so that the push-out block 42 can be popped by the compressed expansion spring 43 to move forwards, and the movable protrusion 422 and the boosting block 61 drive the hearth rod 6 to move forwards until the air inlet 601 below the hearth rod 6 is coincided and communicated with the air outlet channel 3 arranged up and down; meanwhile, the ejector block 42 also impacts the front ejector rod 212 to move the ejector rod 212 forward, so that the moving seal head 21 is caused to leave the air outlet 20, the air guide cabin 2 and the air outlet channel 3 are communicated with air to enter the air outlet channel 3 and then enter the air push pipeline 60 in front of the chamber rod 6 through the air inlet 601 which is overlapped with the air outlet channel, and high-pressure air rushes out the air push pipeline 60 to impact ammunition in front of the chamber rod 6 to eject the ammunition. When the pushing rod 212 moves forward, the moving seal head 21 drives the push rod 211 to compress the push spring 2111 forward, so that after ammunition is fired, the push spring 2111 returns backward to drive the moving seal head 21 to close the air outlet 20 again, and further the system is reset.

Through the pneumatic mode, promote the bullet and throw from the projection tube 7, sound is less, is convenient for conceal. And this catapult 1000 can hang on barrel 100, combines together with current rifle, and light in weight can not influence the weight and the trajectory trend of rifle, and is small simultaneously, is convenient for change and selects, adopts different bullet types with the rifle, reaches the purpose of wonderfully defeating. The catapult 1000 has extremely strong inclusion property, is not limited by the shape characteristics of the projectile seeds, can throw reconnaissance balls, anesthetic needle projectiles, combustion projectiles, toxin needle projectiles, lead projectiles and the like besides common projectile seeds, and is suitable for flexible application in various combat environments. The clamping groove 602 is formed in the air-pushing pipeline 60 of the catapult 1000, injection with a soft base can be clamped by the clamping groove 602 except for the types of bullets, the soft base is clamped into the clamping groove 602 through deformation rotation, the base is deformed again through high-pressure gas during percussion so as to push out the injection in front, the variety of the types of bullets is realized, various different conditions during combat can be better met, and different targets are hidden and hit.

Meanwhile, an air quantity regulating valve 11 is communicated with the air inlet 601 of the air storage chamber 1. The gas storage concentration and the pressure of the gas storage cabin 1 can be controlled and adjusted, so that the distance and the times of ammunition firing are changed, and the ammunition firing distance can be adaptively changed and adjusted according to various different combat environments.

In addition, a silencing device 9 is fixed at the front end of the ejection pipe 7, so that the volume of the ejector 1000 is further reduced, and the aim of concealment is fulfilled. The adopted silencing device 9 comprises an inner pipe sleeved on the projecting pipe 7 and an outer pipe sleeved on the outer layer of the inner pipe, and a plurality of silencing grooves are formed in the inner wall of the inner pipe.

The gun-mounted device 8 comprises a dovetail groove arranged below the gun barrel 100 and a dovetail lug 71 fixed above the ejection tube 7 and matched with the dovetail groove. Or can be combined with various existing firearms by using devices such as a Picatinny guide rail and the like. In order to prevent the original firearm from being disturbed and to prevent the self-action from being affected, the bullet inlet 70 is opened at the side of the ejection tube 7 to feed the bullet at the side, thereby preventing the interference of the upper and lower gun hanging elements.

The above is only the preferred embodiment of the present invention, and any person can make some simple modifications, deformations and equivalent replacements according to the present invention, all fall into the protection scope of the present invention.
