Abstract

The eyepiece sleeve, the eyepiece and the eyepiece device comprise the eyepiece sleeve, an annular groove is formed in the eyepiece sleeve, and an elastic check ring is arranged in the annular groove. During installation, the elastic force of the elastic check ring is applied to one side of the reticle, so that the reticle is fixed in the eyepiece sleeve; when the reticle needs to be disassembled, the elastic check ring deforms due to external force and is separated from the annular groove by means of the annular groove, then the reticle is disassembled, the disassembling process is convenient, and the disassembled reticle is kept complete and can be continuously used.
