Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 2 , a highly efficient and non-destructive folder in this embodiment includes a syringe body 1. A piston rod 2 is slidably connected to the left side of the syringe body 1. A silicone plug 3 is fixed to the right end of the piston rod 2. A limiting ring 4 is fixed between the inner walls of the syringe body 1. An injection spring 5 is sleeved on the outer peripheral wall of the piston rod 2. The injection spring 5 is arranged inside the syringe body 1 and on the left side of the limiting ring 4. The right end of the syringe body 1 is open. A rectangular groove 6 is opened on the top surface of the syringe body 1 and near the right side. A folder body 7 is inserted into the syringe body 1. Two clips 8 are fixed to the top surface of the folder body 7. The right side of the rectangular groove 6 communicates with the right side of the syringe body 1. The two clips 8 are opposite to each other front and back and penetrate through the rectangular groove 6. A fixing mechanism is provided on the syringe body 1. During use, the intraocular lens is folded and fixed by the folder body 7. The folding is efficient and stable and will not damage the intraocular lens. Then, the folded folder body 7 is inserted into the right end of the syringe body 1, and the clips 8 are inserted into the rectangular groove 6. Further, the fixing mechanism provided can form fixed limitation on the clips 8 inside the rectangular groove 6 to prevent the folder body 7 from falling off and damaging the intraocular lens, and improve the structural stability.

[0023] Please refer to Figure 3 , in this embodiment, installation grooves 10 are opened on the opposite sides of the two clips 8. Magnets 11 are fixed in the installation grooves 10. The opposite sides of the two magnets 11 are different magnetic poles. During use, the intraocular lens is clamped by flipping and folding the folder body 7, and the two clips 8 are fixed by the attraction of the two magnets 11, so as to maintain the folded state of the folder body 7. The folding is efficient and stable and will not damage the intraocular lens.

[0024] Please refer to Figures 1 to 5, the fixing mechanism includes a limiting plate 901 slidably connected to the inside of the rectangular groove 6. A receiving groove 905 is formed in the syringe body 1. A connecting plate 906 is slidably connected to the inside of the receiving groove 905. Two connecting rods 907 are fixed to the back surface of the connecting plate 906, passing through the receiving groove 905 and fixed to the front surface of the limiting plate 901. The receiving groove 905 is arranged on the front side of the rectangular groove 6. Two guiding holes are formed in the syringe body 1 and located between the rectangular groove 6 and the receiving groove 905 for the connecting rods 907 to pass through and be slidably connected thereto. A return spring 908 is fixed to the front surface of the connecting plate 906. Further, the limiting plate 901 is pushed towards the receiving groove 905 side, and it pushes the connecting plate 906 to slide inside the receiving groove 905 and compress the return spring 908 through the connecting rods 907. Two limiting rods 902 are fixed to the back surface of the limiting plate 901. Two limiting holes 903 are formed in the front surface of the clamping piece 8. Two limiting grooves 904 are formed in the syringe body 1. The limiting grooves 904 are arranged on the rear side of the rectangular groove 6 and communicate with it. The two limiting grooves 904 and the two limiting holes 903 are opposite to each other front and back. Further, the clamping piece 8 is inserted into the rectangular groove 6, and then the limiting plate 901 is released. The return spring 908 pushes the limiting plate 901 to reset, so that the limiting rods 902 pass through the limiting holes 903 on the clamping piece 8 and then are inserted into the limiting grooves 904 inside the syringe body 1 to fix the folding device main body 7, preventing the folding device main body 7 from falling off and damaging the intraocular lens, and improving the structural stability. At this time, the piston rod 2 can be pushed to perform the injection operation.

[0025] The limiting rods 902, the limiting holes 903, the limiting grooves 904, and the receiving groove 905 are all arc-shaped structures, and the centers of their arc surfaces are all located on the axis of the syringe body 1. Such a structure facilitates the arc-shaped movement of the limiting plate 901, the connecting rods 907, the connecting plate 906, and the limiting rods 902, and thus it is convenient to insert them into the limiting holes 903 and the limiting grooves 904 for fixing.

[0026] The working principle of the above embodiment is as follows:

[0027] During use, the folding device main body 7 is flipped and folded to clamp the intraocular lens, and the two clamping pieces 8 are fixed by the attraction of the two magnetic blocks 11, thereby maintaining the folded state of the folding device main body 7. Further, the limiting plate 901 is pushed towards the receiving groove 905 side, and it pushes the connecting plate 906 to slide inside the receiving groove 905 and compress the return spring 908 through the connecting rods 907. Further, the clamping piece 8 is inserted into the rectangular groove 6, and then the limiting plate 901 is released. The return spring 908 pushes the limiting plate 901 to reset, so that the limiting rods 902 pass through the limiting holes 903 on the clamping piece 8 and then are inserted into the limiting grooves 904 inside the syringe body 1 to fix the folding device main body 7. At this time, the piston rod 2 can be pushed to perform the injection operation.
