[0021] like Figure 2 As shown, in the present invention, the transmission shaft 11 and the rotating shaft 23 are both rotatably connected to the cradle head 3 via the bearing 28 .

[0022] like Figure 2 As shown, in the utility model, a large synchronous wheel tension adjustment plate 7 is fixedly connected to the connection between the motor cover 6 and the cradle head 3, and a small synchronous wheel tension adjustment plate 8 is fixedly connected to the top end of the cradle head 3.

[0023] like Figure 2 As shown, in the utility model, the transmission shaft 11 passes through the large synchronous wheel tension adjustment plate 7 and the small synchronous wheel tension adjustment plate 8, and both the large synchronous wheel tension adjustment plate 7 and the small synchronous wheel tension adjustment plate 8 are provided with through holes for the transmission shaft 11 to pass through.

[0026] Working principle: When the utility model is implemented, the myopic lens is first placed on the lens clamping and adjusting head 29, and then the cylinder driving seat 16 is controlled to start, so that the telescopic piston rod 21 is extended, and the lens clamping and adjusting head 29 is driven to move upward until the myopic lens contacts the lens pasting sheet 27. At this time, the myopic lens is clamped and fixed by the lens clamping and adjusting head 29 and the lens pasting sheet 27, and then the driving motor 9 is controlled to start, and the transmission shaft 11 is driven to rotate through the reducer 10. The rotation of the transmission shaft 11 drives the large synchronous wheel 12 and the micro synchronous wheel 13 set on the outside thereof to rotate. The large synchronous wheel 12 is connected to the large synchronous wheel 2 19 through a large synchronous belt 20. Therefore, when the large synchronous wheel 12 rotates, the large synchronous wheel 2 19 will be driven to rotate. Similarly, when the micro synchronous wheel 13 rotates, the micro synchronous wheel 2 24 will be driven to rotate. Since the large synchronous wheel 2 19 is fixedly sleeved on the outside of the cover mouth 18, and the cylinder cover body 17 is fixedly connected to the cylinder drive seat 16, when the large synchronous wheel 2 19 rotates, it will drive the cylinder drive seat 16 to rotate on the swing tail cover 14, thereby rotating the clamped and fixed myopic lens, thereby adjusting the angle of the myopic lens for easy processing.
