AI Technical Summary
Traditional methods of fixing the lens barrel to the camera body use a threaded connection, which is cumbersome and requires skill, especially when frequently changing the lens barrel, which consumes a lot of time and effort.
The lens barrel is installed and removed by means of a combination of locking ring, limiting ring and return spring. The "T" shaped structure and limiting groove are used to ensure the stable fixation of the lens barrel in the axial and circumferential directions.
The installation and disassembly of the scope tube is simple and quick, improving efficiency and ensuring the stability and accuracy of the equipment under vibration or impact, thus avoiding component wear and malfunction.
