Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, the ophthalmic forceps comprises a first forceps handle 1 and a second forceps handle 2, the tail of the first forceps handle 1 is fixedly connected with the tail of the second forceps handle 2, the head of the first forceps handle 1 is provided with a first cross part 5, the head of the second forceps handle 2 is provided with a second cross part 6, and the first cross part 5 and the second cross part 6 are mutually and reversely crossed; the first intersection 5 is connected with the first clamping part 3, the second intersection 6 is connected with the second clamping part 4, and the first clamping part 3 and the second clamping part 4 are in mirror symmetry.

It can be seen that, in the natural state of the forceps for eyes, the first holding part 3 and the second holding part 4 are combined together, and when a user holds an object through the forceps for eyes, the user needs to press the first forceps handle 1 and the second forceps handle 2 to open the first holding part 3 and the second holding part 4 and then hold the object; after the clamping is finished, the user does not need to continuously extrude the first forceps handle 1 and the second forceps handle 2, the first clamping part 3 and the second clamping part 4 naturally fold and stably clamp objects, and the counter-force type structure is beneficial to saving manpower.
