[0001] The utility model relates to the technical field of fundus mirrors, in particular to a convenient observation mirror for fundus treatment. Background Art

[0002] Using an ophthalmoscope, doctors can clearly see the blood vessels and optic nerve on the retina behind the eyeball. When doctors use an ophthalmoscope to examine patients, the ophthalmoscope can emit a very thin beam of light into the eye. The magnifying glass it has allows doctors to see the part of the retina that the beam reaches. The body of the ophthalmoscope is usually fixed on the handle and exposed to the outside. When the ophthalmoscope is not in use or placed, it is easily damaged by external collisions and other accidents.

[0003] In the prior art, for example, authorization announcement number CN 215017198 U discloses a “dust-proof ophthalmoscope” and specifically discloses that: by installing a push rod in a second fixed rod, the push rod can be limited so that the push rod does not deviate, and then the outer end of the connecting rod is movably sleeved on the surface of the first fixed rod and the inner side of the connecting rod is movably sleeved on the third fixed rod, so that the push rod can be pushed and pulled to drive the cover plate to move up and down to cover and protect the ophthalmoscope body to prevent dust; however, in the above technology, this cover clamping structure does not provide comprehensive protection and has limited protection performance. Moreover, when operating, one hand is required to hold the handle of the body and the other hand to push and pull the push rod, which is not convenient. Therefore, the present invention proposes a portable fundus treatment observation mirror to solve the problems existing in the prior art. Utility Model Content
