[0034] The limiting part 6 further comprises two groups of circular ends 61, a hand-held frame 62 and two groups of rotating shafts 63;

[0035] The two groups of circular ends 61 are respectively clamped in the corresponding limiting grooves 51 from top to bottom, the hand-held frame 62 is in U shape, the two ends of which are respectively fixed with the two groups of circular ends 61, and the two groups of rotating shafts 63 are respectively rotatably installed in the inner sides of the two groups of corresponding circular ends 61, and the inner sides of the two groups of rotating shafts 63 are fixed with the frame 64.

[0036] Specifically, after the single-side coating of the lens is completed, the operator can rotate the frame 64 through the hand-held frame 62 to make the other side of the lens face the evaporator 2, so as to realize the continuous coating of both sides.

[0037] The rotating shaft 63 is in a squeezed state with the corresponding circular end 61, and needs to be manually driven to rotate, so as to avoid unnecessary rotation.

[0038] The diameter of the frame 64 is smaller than that of the mounting port 5, and the frame 64 can be smoothly rotated in the mounting port 5 without the need to take out the frame 64 for adjustment.
