The interchangeable objective lens is disposed inside the main lens barrel housing, in the lower middle part. The optical lens is disposed inside the interchangeable objective lens barrel, and the glass retaining ring is disposed below the optical lens. An upper magnetic attraction structure is disposed in a groove below the main lens barrel assembly, and a lower magnetic attraction structure is disposed in a groove on the upper end face of the interchangeable objective lens. The upper and lower magnetic attraction structures are opposite each other and attract each other, so that the interchangeable objective lens is connected to the lower part of the main lens barrel assembly.

[0006] The interchangeable objective lens housing has one downward-facing fixing post on each of its lower sides, and the fixing posts are symmetrically arranged on both sides of the lower part of the interchangeable objective lens housing; each fixing post on both sides has one wire through hole, and the center lines of the two wire through holes are on the same straight line;

[0007] The upper magnetic attraction structure and the lower magnetic attraction structure are an upper magnetic ring structure and a lower magnetic ring structure.

[0008] The wire handle is semi-circular; the lower edge of the interchangeable objective lens has several small magnets; when the wire handle is retracted to a horizontal position, the wire handle is attracted to the small magnets.

[0009] The upper end of the interchangeable objective lens barrel is provided with an upper annular flange, and the side ring of the upper annular flange is provided with threads. The upper annular flange is connected to the upper end of the interchangeable objective lens housing by threads.

[0010] A ring light is installed inside the objective lens housing and outside the interchangeable objective lens housing to illuminate the optical glass inside the quick-change objective lens structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the objective lens mounting method is changed to magnetic attachment, which greatly saves working time and brings convenience to the work of using a microscope. Attached Figure Description
