[0042] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings:

[0043] First, remove the empty magazine body 5 from the launcher, then load the sponge soft bullet 13 into the magazine body 5, and then insert the magazine body 5 with the sponge soft bullet 13 into the magazine seat body 4, and then turn the main locking paddle 15 or the auxiliary locking paddle 16 by finger, so that the main locking paddle 15 enters the paddle slot of the magazine body 5, and the magazine body 5 completes the limit fixation, and at the same time, the main locking paddle 15 and the auxiliary locking paddle 16 enter the self-locking state.

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

[0045] As the force transmission rod 42 moves backward, the supporting transfer roller pin 57, the lower pressing seat 58 of the projectile body and the projectile body push rod 59 will be driven to move backward synchronously until the projectile body push rod 59 moves to the rear of the sponge soft projectile 13. Under the thrust of the projectile body push spring 11, the sponge soft projectile 13 moves upward and presses against the projectile body limit baffle 56. At the same time, as the loading actuator 43 moves backward, the projectile body firing force storage spring 40 is gradually compressed to achieve the accumulation of spring force until the dynamic 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 thrust of the trigger ring reset spring 55, the dynamic trigger ring 54 can stay firmly in the clamping ring groove 47, thereby achieving the grasping of the hollow piston 38.

[0046] When the hollow piston 38 completes the grabbing, it pushes the finger-pull handle 35 forward, driving the slide rod 36 to move forward along the guide slot 62, and then driving the slide sleeve 37 to move forward along the launch tube 10, and the force transmission rod 42 and the loading actuator 43 will move forward synchronously with the slide sleeve 37.

[0047] As the force transmission rod 42 moves forward, the support transfer roller pin 57, the projectile lower pressure seat 58 and the projectile push rod 59 will be driven to move forward synchronously. The projectile push rod 59 moving forward will push the topmost sponge soft bullet 13 forward into the launch tube 10 until the rear end 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 captured hollow piston 38 will move forward with the sliding sleeve 37, and the projectile launch force storage spring 40 in a compressed state will also move forward with the sliding sleeve 37 until the sliding sleeve 37 rests on the front annular limit seat 33, and the dynamic trigger ring 54 is just above the trigger top block 23. At this time, the loading and force storage process are completed synchronously.

[0048] When the loading and charging process is completed, the right index finger releases the finger-pull handle 35, and then presses the safety slide pin 22 from the side to move the trigger release groove 29 on the safety slide pin 22 to just below the safety slide pin slot 26 on the finger buckle pull rod 19. Then the right hand holds the armrest support bracket 21 from below, and the left index finger extends in front of the finger buckle body 18. Then both hands cooperate to adjust the position of the launcher until the front end of the launch tube 10 is aimed at the target.

[0049] When the above-mentioned preparatory action is completed, the left index finger presses the finger button body 18 backward, driving the finger button pull rod 19 to move backward, and the pull rod reset spring 20 is compressed. When the smooth transition inclined surface 25 passes through the anti-friction pin 31, the backward horizontal action of the finger button pull rod 19 will be synchronously converted into the upward rising movement of the anti-friction pin 31 and the trigger top block 23. As the trigger top block 23 rises, the trigger ring 54 will be pushed upward, and the trigger ring reset spring 55 will be compressed until the dynamic trigger ring 54 is completely removed from the clamping ring groove 47, realizing the release of the hollow piston 38. At the same time, the projectile launching force storage spring 40 will quickly extend and The output thrust force further pushes the hollow piston 38 to move backward at high speed along the cylinder sleeve 39. Since the rear end pipe opening of the launch tube 10 has been sealed by the fourth sealing ring 61, the chamber of the cylinder sleeve 39 can only be connected with the inside of the launch tube 10 through the vent hole 51. During the process of the hollow piston 38 moving backward at high speed, the air in the chamber of the cylinder sleeve 39 will be pressed into the launch tube 10 through the vent hole 51 at high speed by the moving hollow piston 38. The generated compressed air force serves as the driving force for pushing the sponge soft bullet 13 to be launched, so that the sponge soft bullet 13 can be ejected at high speed along the launch tube 10, and finally the launch of the sponge soft bullet 13 is realized.

[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 invention. All equivalent implementations or changes that do not deviate from the present invention are included in the protection scope of the present invention.
