[0014] 1. The present invention designs a two-stage high-low pressure structure, the first stage high-low pressure structure is located in the launch assembly, and the second stage high-low pressure structure is located in the projectile assembly. Through the ingenious structural design, a better elastic force and a more consistent exit velocity can be obtained, so that the present invention has better intermediate trajectory and outer trajectory characteristics;

[0015] 2. The present invention sets a range-extending structure in the projectile assembly, by loading propellant in the secondary high-pressure chamber, using the gunpowder gas generated by the combustion of the propellant to be ejected from the tail nozzle at high speed, so as to achieve secondary boosting of the projectile assembly, so that the present invention can be launched by relying on a conventional launcher, but with a greater effective range;

[0016] 3. The present invention ignites the annular explosive by means of a flame delay tube to realize high-speed spraying of kinetic energy projectiles and OC stimulating powder, so that the present invention also has good striking kinetic energy at the end point. By controlling the amount of the annular explosive, non-lethal kinetic strikes on the target can be achieved. At the same time, through the high-speed spraying of the OC stimulating powder, stimulation and dispersal of the target population can be achieved, so that the present invention has the dual non-lethal effects of kinetic strike and stimulation and dispersal;

[0017] 4. The propellant of the present invention adopts smokeless gunpowder, which can obtain a more consistent exit velocity, and at the same time, the amount of muzzle smoke is less, which will not interfere with the normal tactical actions of the user. The present invention does not produce excessive gunpowder residue in the barrel, thereby not affecting repeated shooting and projectile accuracy, thereby making the present invention have higher battlefield applicability;

[0018] 5. The annular explosive expansion charge in the present invention causes the kinetic energy projectile, OC stimulation powder to separate from the outer projectile and the inner projectile, which can reduce the accidental damage of the outer projectile and the inner projectile to living targets, and further improve the safety of the present invention.
