Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element to which the reference is made must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "connected," and the like are to be construed broadly, and for example, "connected" may be either fixedly connected or detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-3, the present invention provides an embodiment: an ophthalmic drug delivery device comprises a mounting plate 3, wherein a first connecting block 5 is mounted on the outer wall of the mounting plate 3 and is connected with an eyelid opening arm 7 through a movable pin shaft 6, a second connecting block 8 is mounted on the lower surface of the eyelid opening arm 7, the number of the second connecting blocks 8 is two, the two second connecting blocks 8 are connected through an elastic arc-shaped plate 10, a circular push-pull plate 1 is arranged on one side of the mounting plate 3, the circular push-pull plate 1 is mounted on one end of a push-pull rod 2, a piston 12 is mounted at the other end of the push-pull rod 2 and is positioned inside an injection cylinder 4, one end of the injection cylinder 4 penetrates through a first through hole 13 and is connected with a nipple 11, the other end of the nipple 11 penetrates through a second through hole 14 on the elastic arc-shaped plate 10, the number of the first connecting blocks 5 is four, the four connecting blocks are respectively mounted at the upper end, the lower end, the front end and the rear end, the first through hole 13 is opened at the center of the outer wall of the mounting plate 3, the inside of the nipple 11 is communicated with the inside of the injection cylinder 4, and the second through hole 14 is opened at the center of the elastic arc-shaped plate 10.
