During the rotation of the adjustment disk 202, the movable ring 210 is driven to rotate inside the movable groove 208, thereby improving the stability of the rotation process of the adjustment disk 202, and when the movable ring 210 rotates, it drives the limiting ring 207 to rotate inside the limiting groove 209, thereby supporting the position of the adjustment disk 202 and preventing the adjustment disk 202 from rotating during the rotation process.
