In this embodiment: the objective lens assembly 31 is connected to the connection base 30, the objective lens assembly 31 comprises an objective lens base and an objective lens, the objective lens is arranged on the objective lens base, and the objective lens base is connected to the connection base 30. As shown in fig. 4 and 5: the connecting seat 30 is in an L shape, one side of the L-shaped connecting seat 30 is provided with a connecting groove 300, and a fixing piece 32 fixes the objective lens assembly 31 and the connecting seat 30 through the connecting groove 300. That is, the connection base 30 and the objective lens assembly 31 are connected together, and both move relative to the lens housing 1.

The focusing assembly can be directly used for driving the lens body shell 1 to move, and can also control the objective lens assembly 31 to move relative to the lens body shell 1, wherein the former is used for coarse focusing, the latter is used for fine focusing, and the combination of the two can realize accurate focusing of a microscope.

In this embodiment: the focus assembly includes a handle lever 40, a focus lever 41, and an operating member 42. The handle lever 40, the focus lever 41, and the operating member 42 are coaxially provided. The specific method is as follows:

the handle lever 40 is used for adjusting the position of the mirror body shell 1, and is used as a reference in the working state, the handle lever 40 is positioned at the bottom of the mirror body shell 1 and extends in a direction away from the mirror body shell 1, specifically, extends obliquely downwards, so that the hands of a doctor are closer to the doctor during operation, the force is conveniently applied, and the embarrassment of the patient is avoided further away from the patient. The handle bar 40 is provided with only one, and the movement of the mirror housing 1 by the handle bar 40 can be controlled by one hand through the design of the extension angle. The handle bar 40 is internally provided with a hollow space in the axial direction thereof.

The focusing rod 41 is inserted into the cavity of the handle rod 40, and the focusing rod 41 can rotate around the axis thereof in the cavity, the upper end part of the focusing rod 41 extends out of the handle rod 40 and is in transmission connection with the objective lens assembly 31, namely, the objective lens assembly 31 can be driven to move relative to the lens body shell 1 to focus by rotating the focusing rod 41.

Thus, the rotation operation member 42 can drive the focusing rod 41 to rotate, and drive the objective lens assembly 31 to move and focus relative to the lens body housing 1. The specific method is as follows: as shown in fig. 9: the operation member 42 and the focusing lever 41 are connected by a connection assembly, and in this embodiment: the connecting assembly comprises a threaded pin 430, a sleeve body 431 and a fastening piece, wherein the threaded pin 430 penetrates through the operating piece 42 to be in threaded connection with the focusing rod 41, the sleeve body 431 is fixedly sleeved on a non-threaded section of the periphery of the threaded pin 430 and is positioned in the rotating groove 400, the width of the sleeve body 431 is matched with the width of the rotating groove 400, so that the sleeve body 431 can only slide in the inner periphery of the rotating groove 400, the operating piece 42 and the threaded pin 430 are fastened by the fastening piece, and the fastening piece can be a screw or the like. In the process of rotating the operating member 42, after the sleeve body 431 abuts against the groove walls at two ends of the rotating groove 400, the continuous rotation of the operating member 42 can be limited, so that the circumferential rotation of the operating member 42 is limited, and the rotatable amplitude of the operating member 42 can be controlled by the extension length of the rotating groove 400; meanwhile, since the width of the housing 431 is matched with the width of the rotation groove 400, the upper and lower groove walls of the rotation groove 400 can restrict the axial movement of the operating member 42 by the housing 431.

In addition, the lower end of the handle bar 40 is connected with a grip portion 44, and the grip portion 44 is provided with a stripe anti-slip structure, and the operating member 42 is sleeved on the handle bar 40 at the upper part of the grip portion 44, wherein the distance between the grip portion and the grip portion is not more than 1cm. In this way, when a doctor operates, he can hold the holding part 44 to move the mirror body shell 1, and can rotate the operating member 42 to focus by extending his thumb, and the operating member 42 is closer to the mirror body shell 1, so that the operation is more convenient, and the probability of misoperation is reduced. Of course, the grip portion 44 may be formed directly at the lower end portion of the handle bar 40. As shown in fig. 3: the cavity of the handle bar 40 penetrates the lower end portion of the handle bar 40 so that the focusing bar 41 can be penetrated from the lower end portion of the handle bar 40, and the focusing bar 41 is restrained in the cavity by screwing the grip portion 44.

The focusing assembly further comprises a fixing seat 45 and a transmission rod 46, and as shown in fig. 3-5, the fixing seat 45 and the transmission rod 46 are arranged in the mirror body shell 1. Wherein:

the fixing base 45 is fixedly connected to the mirror body housing 1, and the upper end portion of the handle lever 40 is connected to the fixing base 45, specifically through threaded connection. The fixing seat 45 is provided with a through hole, the transmission rod 46 is movably arranged in the through hole along the axial direction of the transmission rod 46, and the axial direction of the transmission rod 46 is consistent with the moving direction of the objective lens assembly 31, so that the transmission rod 46 can only move in the through hole of the fixing seat 45 and also plays a role in moving and guiding. As shown in fig. 6: the fixing base 45 is provided with a transmission groove 450 communicated with the through hole, and the upper end part of the focusing rod 41 is matched with the transmission rod 46 through the transmission groove 450. The specific method is as follows: the focusing rod 41 and the transmission rod 46 are matched through teeth, the teeth on the focusing rod 41 are distributed around the circumference of the focusing rod, the teeth on the transmission rod 46 are distributed along the axial direction of the transmission rod, and the focusing rod 41 rotates to drive the transmission rod 46 to move so as to drive the objective lens assembly 31 to move.

In this embodiment: the transmission rod 46 is connected with the connecting seat 30 instead of being directly connected with the objective lens assembly 31, so that simple rigid connection can be avoided, adjustment is convenient, and blocking is prevented; and when the inside is damaged, the connection seat 30 can be replaced for processing.

In addition, the focusing assembly further includes a limiting member 47 disposed on the fixing base 45 for limiting the axial rotation of the driving rod 46. As shown in fig. 4, the limiting member 47 is fixed in the through hole of the fixing seat 45 by a fixing member, a first limiting plane 460 is provided on the driving rod 46, a second limiting plane 470 is provided on the limiting member 47, and the first limiting plane 460 is attached to the second limiting plane 470.
