[0053] In the embodiment of the present utility model, the positioning mechanism 3 is arranged on the lifting mechanism 2, so that the positioning mechanism can move up and down following the lifting mechanism 2. And the positioning mechanism 3 is movably arranged on the lifting mechanism 2, which is convenient for finely adjusting the position of the positioning mechanism, further aligning the positioning pin with the structure to be positioned, and increasing the positioning accuracy; by arranging the positioning arm, it is also convenient to align the positioning pin with the structure to be positioned, and reduce the floor area and weight of the mechanism, further saving space.
[0054] Please refer to Figure 3 , in the embodiment of the present utility model, optionally, a positioning hole 32 is arranged on the positioning arm 31, and the positioning pin 4 is placed in the positioning hole 32.
[0055] In the embodiment of the present utility model, by arranging the positioning hole 32, the positioning pin 4 becomes a movable mechanism, and the parts can be easily taken after the operation is completed, ensuring the convenience of the operation, improving the durability of the mechanism, and reducing the cost.

[0060] Please refer to Figure 6 , the main positioning pin 41 includes: a first positioning region 411 and a second positioning region 412. The cross-sections of both the first positioning region 411 and the second positioning region 412 are circular, and the diameter of the first positioning region 411 is smaller than the diameter of the second positioning region 412.

The positioning pin 4 cooperates with the corresponding through holes on the first structure to be positioned 100 and the second structure to be positioned 200 for positioning. Since the diameter of the through hole of the second structure to be positioned 200 is smaller than the diameter of the through hole of the first structure to be positioned 100, the diameter of the first positioning area 411 is smaller than the diameter of the second positioning area 412; the diameter of the first positioning area 411 cooperates with the corresponding through hole on the second structure to be positioned 200; the diameter of the second positioning area 412 cooperates with the corresponding through hole on the first structure to be positioned 100; the diameter of the third positioning area 421 is smaller than the diameter of the fourth positioning area 422; the diameter of the third positioning area 421 cooperates with the corresponding through hole on the second structure to be positioned 200; the diameter of the fourth positioning area 422 cooperates with the corresponding through hole on the first structure to be positioned 100, so that the thicker lower part positions the small gasket, and the thinner upper part passes through the small holes of the large frame, ensuring the accuracy and avoiding the phenomenon of non-concentricity of the two parts resulting in a double eyelid.
