[0002] Early recoilless guns were not equipped with advanced fire control systems, so there was no special mechanism for disassembling fire control aiming devices. With the advancement of technology and the improvement of military needs, recoilless guns have gradually been equipped with more accurate sights and fire control systems to achieve rapidity and accuracy in aiming and shooting. The connection mechanism between the recoilless gun and the fire control aiming device is an important guarantee for ensuring the effectiveness of the system.

[0003] The design of the quick-release connection mechanism stems from the need for rapid deployment and efficient combat on the battlefield. Traditional connection methods often require cumbersome steps and a long time to make precise adjustments in a safe environment, which is obviously disadvantageous in the ever-changing battlefield environment. In contrast, the design of the quick-release connection mechanism greatly simplifies the installation and disassembly process of the fire control aiming device, which can be completed quickly in a short time, allowing the recoilless gun to be put into combat more quickly, improving the flexibility and response speed of combat, and greatly improving combat efficiency.

[0004] Traditional connection methods may be limited to specific fire control and aiming device models and specifications, while quick-release connection mechanisms are usually more versatile and interchangeable, which means that it can be adapted to multiple types of fire control and aiming devices, improving the flexibility and battlefield adaptability of recoilless guns.

[0005] Although the quick-release connection mechanism focuses on speed, it does not sacrifice stability and accuracy. Through precise design and advanced manufacturing processes, the connection mechanism takes into account factors such as vibration and impact in the battlefield environment, ensuring that the fire control aiming device can remain stable during use and improve shooting accuracy.
