When disassembly is required, it is only necessary to loosen the saddle screw without the need for baking, which has the advantage of convenient disassembly.

[0007] A further solution is that the eyepiece frame is set as a hollow structure, and a mounting groove is opened inside the eyepiece frame; the eyepiece retaining ring is set in the mounting groove, and an annular flange is set on the outer side of the eyepiece retaining ring, and a mounting hole is opened in the annular flange along the axial direction, the mounting hole is connected to the mounting groove, the saddle screw passes through the mounting hole and is connected to the mounting groove, and the thread of the saddle screw is embedded in the groove wall of the mounting groove.

[0008] A further solution is that the thread of the saddle screw is embedded in the peripheral wall of the eyepiece retaining ring.

[0009] A further solution is that the mounting groove extends along the circumference of the eyepiece outer frame, and in the axial direction, the mounting groove includes a small diameter portion, a connecting portion and a large diameter portion in sequence; the end of the eyepiece retaining ring away from the annular flange is arranged in the small diameter portion, the annular flange is arranged on the side of the large diameter portion facing away from the connecting portion, and the thread of the saddle screw is embedded in the groove wall of the large diameter portion.

[0010] A further solution is that one end of the eyepiece retaining ring provided with an annular flange protrudes from the end of the lens body, and the wall thickness of the end of the eyepiece retaining ring provided with the annular flange is smaller than the wall thickness of the other end thereof.

[0011] A further solution is that a first positioning portion is provided on one end of the lens body close to the eyepiece frame, and a second positioning portion is provided on the eyepiece frame. The second positioning portion and the first positioning portion cooperate in a concave-convex manner to limit the eyepiece frame from rotating relative to the lens body along its axis.

[0012] It can be seen from the above scheme that by providing the first positioning portion and the second positioning portion with concave-convex cooperation, it is beneficial to achieve the orientation effect of the eyepiece frame and prevent the eyepiece frame from rotating relative to the lens body.

[0013] A further solution is that the first positioning portion is set as a positioning groove, the positioning groove is recessed in the outer wall of the lens body, and the positioning groove extends along the axial direction of the lens body; the second positioning portion is set as a positioning protrusion, the positioning protrusion protrudes from the inner wall of the eyepiece frame, and the positioning protrusion is embedded in the positioning groove.
