[0042] The following describes a usage process of the present utility model with reference to the drawings:

[0043] First, remove the empty magazine body 5 from the launcher, then load the sponge soft projectile 13 into the magazine body 5, and then insert the magazine body 5 loaded with the sponge soft projectile 13 into the magazine seat body 4. Then, turn the main locking flap 15 or the secondary locking flap 16 with fingers, so that the main locking flap 15 enters the flap card slot of the magazine body 5, and the magazine body 5 is completed with limit fixation. At the same time, the main locking flap 15 and the secondary locking flap 16 enter the self-locking state.

[0044] Next, hold the grip 7 of the launcher with the left hand, hook the finger-pulling handle 35 with the right index finger, and then pull the finger-pulling handle 35 backward with force, driving the sliding rod 36 to move backward along the guiding chute 62, and then driving the sliding sleeve 37 to move backward along the launch tube 10. The force transmission rod 42 and the loading actuator 43 will move backward synchronously with the sliding sleeve 37.

[0045] With the backward movement of the force transmission rod 42, the support transfer roller pin 57, the projectile pressing seat 58 and the projectile push rod 59 will move backward synchronously until the projectile push rod 59 moves to the rear of the sponge soft projectile 13. Under the thrust of the projectile top-pushing spring 11, the sponge soft projectile 13 moves upward and abuts against the projectile limiting baffle 56. At the same time, with the backward movement of the loading actuator 43, the projectile launch energy storage spring 40 is gradually compressed to realize the accumulation of spring force until the moving trigger ring 54 in the loading actuator 43 enters the clamping ring groove 47 on the clamping section 44 of the hollow piston 38. Under the top thrust of the trigger ring return spring 55, the moving trigger ring 54 can stay firmly in the clamping ring groove 47, thereby realizing the grasping of the hollow piston 38.

[0046] After the hollow piston 38 completes the grasping, push the finger-pull handle 35 forward, driving the sliding rod 36 to move forward along the guiding chute 62, and then driving the sliding sleeve 37 to move forward along the launch tube 10. The force-transfer rod 42 and the loading actuator 43 will move forward synchronously with the sliding sleeve 37.

[0047] As the force-transfer rod 42 moves forward, it will drive the support transfer roller pin 57, the projectile pressing seat 58, and the projectile push rod 59 to move forward synchronously. The forward-moving projectile push rod 59 will push the top sponge soft projectile 13 forward into the launch tube 10 until the rear end nozzle of the launch tube 10 is sealed by the fourth sealing ring 61. At the same time, as the sliding sleeve 37 moves forward, the grasped hollow piston 38 will move forward together with the sliding sleeve 37, and the projectile launch energy storage spring 40 in the compressed state will also move forward together with the sliding sleeve 37 until the sliding sleeve 37 abuts against the front annular limit seat 33, and at the same time, the moving trigger ring 54 is exactly above the trigger top block 23. At this time, the loading and energy storage processes are completed synchronously.

[0048] After the loading and energy storage processes are completed, release the finger-pull handle 35 with the right index finger, and then press the safety sliding pin 22 from the side, so that the trigger unlocking groove 29 on the safety sliding pin 22 moves to directly below the safety sliding pin slot 26 on the finger-pull rod 19. Then hold the armrest support bracket 21 with the right hand from below, and at the same time, insert the left index finger in front of the finger-pull body 18. Subsequently, cooperate with both hands to adjust the position of the launcher until the front end nozzle of the launch tube 10 is aligned with the target.

[0049] After the above preparatory actions are completed, press the finger-pull body 18 backward with the left index finger, driving the finger-pull rod 19 to move backward, and the pull rod return spring 20 is compressed. When the smooth transition inclined surface 25 passes the antifriction pin post 31, the backward horizontal movement of the finger-pull rod 19 will be synchronously converted into the upward rising movement of the antifriction pin post 31 and the trigger top block 23. As the trigger top block 23 rises, it will push the moving trigger ring 54 upward, and the trigger ring return spring 55 is compressed until the moving trigger ring 54 completely moves out of the clamping ring groove 47, realizing the release of the hollow piston 38. At the same moment, the projectile launch energy storage spring 40 will quickly elongate and output a top thrust, thereby driving the hollow piston 38 to move backward at high speed along the cylinder sleeve 39. Since the rear end nozzle of the launch tube 10 has been sealed by the fourth sealing ring 61, the chamber of the cylinder sleeve 39 can only communicate with the inside of the launch tube 10 through the vent hole 51. During the backward high-speed movement of the hollow piston 38, the air in the chamber of the cylinder sleeve 39 will be rapidly pressed into the launch tube 10 by the moving hollow piston 38 through the vent hole 51, and the generated compressed air power serves as the driving force to push the sponge soft projectile 13 to be launched, enabling the sponge soft projectile 13 to be shot out at high speed along the launch tube 10, finally realizing the launch of the sponge soft projectile 13.

[0050] After the sponge soft bullet 13 is launched from the launch tube 10, the pressure of the left index finger on the finger button body 18 can be released, the pull rod reset spring 20 is extended, pushing the finger button pull rod 19 and the finger button body 18 to reset, the anti-friction pin 31 is out of contact with the smooth transition slope 25, and the triggering top block 23 automatically descends under the action of gravity until the anti-friction pin 31 falls back into the trigger limit groove 24. At the same time, the projectile launch storage spring 40 is extended to the initial state, and under the top thrust of the projectile launch storage spring 40, the hollow piston 38 is pressed against the rear annular limit seat 34 again.

[0051] When it is necessary to continue the firing action of the sponge soft bullet 13, the finger-pull handle 35 is repeatedly pulled back and pushed forward, and the finger-button body 18 is pressed, so that the loading, power storage, and firing of the sponge soft bullet 13 can be realized. When the firing action of the sponge soft bullet 13 is not to be continued, the safety slide pin 22 only needs to be pressed in the reverse direction, so that the trigger release groove 29 on the safety slide pin 22 is moved away from the safety slide pin slot 26 on the finger-button pull rod 19, and the complete pin body part of the safety slide pin 22 is moved into the safety slide pin slot 26 on the finger-button pull rod 19, so as to realize the limit fixation of the finger-button pull rod 19, and the finger-button body 18 is also simultaneously limited and fixed.

[0052] The solutions in the embodiments are not intended to limit the protection scope of the present utility model. All equivalent implementations or changes that do not deviate from the protection scope of the present utility model are included in the protection scope of the present utility model.
