[0031] See also Figure 1-3 As shown, this embodiment is a special clip for ophthalmic foreign bodies, comprising:

[0032] A foreign body clamp body, the foreign body clamp body comprises a forceps arm 11;

[0033] The movable assembly includes a slide 21, a pulley 22, a positioning column 23, a fixing nut 24 and a fixing plate 25;

[0034] The slide groove 21 is opened at one side of the upper end of the forceps arm 11, the pulley 22 is placed at the bottom end of the slide groove 21, the positioning column 23 is fixedly connected to the upper end of the pulley 22, the fixing nut 24 is threadedly connected to the outer surface of the positioning column 23, and the fixing plate 25 is fixedly connected to the top end of the positioning column 23;

[0035] The slide groove 21 is used to guide the movement of the pulley 22, the pulley 22 is used to drive the positioning column 23 to move, the positioning column 23 is used to fix the position of the pulley 22 and support the fixing plate 25, the fixing nut 24 is used to fix the positioning column 23 in the inner position of the slide groove 21, and the fixing plate 25 is used to keep the two groups of positioning columns 23 at the same distance at all times;

[0036] The foreign body clamp body also includes a silicone clamp head 12;

[0037] The silicone chuck 12 is fixedly connected to the outer end of the tweezer arm 11;

[0038] The tweezer arm 11 is used to drive the silicone chuck 12 to move, and the silicone chuck 12 is used to clamp foreign matter;

[0039] The slide groove 21 is a T-shaped structure, and the positioning column 23 passes through the slide groove 21 and extends outward;

[0040] When the fixing plate 25 is moved, the positioning column 23 is moved under the drive of the fixing plate 25, and the positioning column 23 drives the pulley 22 to rotate inside the slide groove 21;

[0041] The outer surface of the positioning column 23 has a thread structure opened relative to the fixing nut 24, and the fixing nut 24 is located below the fixing plate 25;

[0042] The fixing nut 24 is screwed upward to separate the fixing nut 24 from the top of the forceps arm 11, so that the fixing nut 24 does not fix the positioning column 23. The fixing nut 24 is screwed downward to make the bottom end of the fixing nut 24 contact with the top of the forceps arm 11, so that the fixing nut 24 fixes the positioning column 23 inside the slide groove 21.

[0043] Working principle: when the opening size of the silicone chuck 12 needs to be adjusted, the fixing nut 24 is screwed upwards to separate the bottom end of the fixing nut 24 from the top end of the tweezer arm 11, and the fixing nut 24 does not fix the positioning column 23, and then an outward force is applied to the fixing plate 25, and the fixing plate 25 moves outwards to drive the positioning column 23 to move outwards, and the positioning column 23 moves outwards to drive the pulley 22 to move outwards inside the slide groove 21. At this time, under the limitation of the fixing plate 25, the spacing between the two groups of positioning columns 23 is kept constant, so that the positioning column 23 applies an inward force to the tweezer arm 11, and the tweezer arm 11 moves inwards to drive the silicone chuck 12 to move inwards, so that the opening of the silicone chuck 12 can be reduced, and then the fixing nut 24 is screwed downwards to fix the positioning column 23;

[0044] When the opening of the silicone chuck 12 needs to be enlarged, the above steps can be performed in reverse.

[0045] See also Figure 4 As shown, this embodiment is based on the above embodiment and also includes:

[0046] A fixing assembly, the fixing assembly includes a fixing slot 31, a movable block 32, a telescopic spring 33, a support plate 34 and a collar 35;

[0047] The fixed groove 31 is opened at one end of the outer side of the forceps arm 11, the movable block 32 is placed at both ends of the inner position of the fixed groove 31, the telescopic spring 33 is fixedly connected to the inner side of the movable block 32, the support plate 34 is fixedly connected to the outer end of the movable block 32, and the collar 35 is fixedly connected to the outer end of the support plate 34;

[0048] The fixing groove 31 is used to place the movable block 32, the movable block 32 is used to support the support plate 34, the telescopic spring 33 is used to drive the movable block 32 to reset, the support plate 34 is used to fix the ring 35, and the ring 35 is used to be sleeved on the outer surface of the finger;

[0049] The fixing groove 31 is a convex structure, and the movable block 32 is an L-shaped structure;

[0050] When the outer end of the movable block 32 is in contact with the inner end of the fixed groove 31, the telescopic spring 33 is in a compressed state;

[0051] Working principle: when it is necessary to use the ring 35 to cover the finger, an inward force is applied to the movable block 32, and the movable block 32 moves inward to compress the telescopic spring 33, and then the movable block 32 is placed in the fixed groove 31. Under the elastic force of the telescopic spring 33, the movable block 32 moves outward until the outer end of the movable block 32 contacts the inner side of the fixed groove 31. At this time, the telescopic spring 33 is still in a compressed state to generate elastic force, so that the movable block 32 is fixed in the fixed groove 31. The movable block 32 fixes the support plate 34 and the ring 35 at the outer position of the tweezers arm 11, and the finger can be put into the ring 35, so that it will not slide when the foreign body clamp body is used.
