[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an optical colposcope with electric zoom function, comprising a main horizontal arm support 1, one side of the upper surface of the main horizontal arm support 1 is rotatably connected to a sub-horn support 2, one side of the upper surface of the sub-horn support 2 is fixedly connected to a support rod 3, one side of the outer wall of the support rod 3 is provided with an adjustment component 4, one side of the outer wall of the support rod 3 is rotatably connected to a support plate 5, a microscope main mirror 6 is fixedly connected to the upper surface of the support plate 5, one side of the outer wall of the microscope main mirror 6 is fixedly connected to a binocular lens barrel 7, the other side of the outer wall of the microscope main mirror 6 is rotatably connected to a focusing knob 8, the adjacent side of the focusing knob 8 is fixedly connected to a protective cover 9, and the protective cover 9 A motor 10 is fixedly connected to one side of the outer wall, an adjusting gear 11 is fixedly connected to the output end of the motor 10, the adjusting gear 11 is meshed and connected with the focusing knob 8, a handle 12 is fixedly connected to the lower surface of the support plate 5, an adjusting button 13 is arranged on one side of the outer wall of the handle 12, the adjusting button 13 is electrically connected to the motor 10, and an adjusting button 2 14 is arranged on the other side of the outer wall of the handle 12; the adjusting assembly 4 includes an adjusting bolt 401, one end of the adjusting bolt 401 is fixedly connected to one side of the outer wall of the support rod 3, the adjusting bolt 401 is slidably connected to the support plate 5, and the outer wall of the adjusting bolt 401 is threadedly connected with an adjusting nut 402;

[0032] Specifically, when the microscope main mirror 6 reaches the lesion, in order to allow the user to observe the lesion more accurately, it is necessary to adjust the support plate 5 by rotating the adjustment nut 402. The outer wall of the adjustment bolt 401 of the support plate 5 can be rotated, so that the angle of the support plate 5 can be easily adjusted, so that the observation of the sample under the microscope is clearer. After adjusting the angle of the support plate 5, the next step is to adjust the focal length of the microscope. At this time, the adjustment button 13 on the upper part of one side of the handle 12 can be pressed to send a signal to control the start of the motor 10. After the motor 10 is started, it will drive the adjustment gear 11 to rotate, thereby realizing the meshing rotation of the focusing knob 8. In this way, the user can accurately adjust the focal length of the microscope main mirror 6 by rotating the focusing knob 8, so that the observed image is clearer. In the process of adjusting the focal length, if further adjustment is required, the adjustment button 13 on the lower part of one side of the handle 12 can be pressed. In this way, the adjustment of the opposite focal length of the microscope main mirror 6 can be achieved, so that the observer can adjust the depth and clarity of observation according to actual needs.

[0033] Reference Figure 1 and Figure 3 , a support column 15 is fixedly connected to the lower surface of the cross arm main bracket 1, and a sleeve 16 is provided on the outer wall of the support column 15; a protective shell 17 is fixedly connected to the lower surface of the sleeve 16, and a movable base 18 is provided on the lower surface of the protective shell 17; a motor 2 19 is fixedly connected to one side of the outer wall of the protective shell 17, a transmission shaft 20 is fixedly connected to the output end of the motor 2 19, and a worm 21 is fixedly connected to the outer wall of the transmission shaft 20; an adjusting screw 23 is rotatably connected inside the protective shell 17, and a worm wheel 22 is fixedly connected to the outer wall of the adjusting screw 23, and the worm wheel 22 is meshed with the worm 21; a limit rod 24 is fixedly connected to the upper surface of the protective shell 17, and the limit rod 24 is slidably connected to the inside of the support column 15, and the support column 15 is threadedly connected to the adjusting screw 23; the motor 2 19 is electrically connected to the adjusting button 2 14;

[0034] Specifically, first, the medical staff will press the adjustment button 2 14 on one side of the outer wall of the handle 12. This operation will send a signal to the control system to start the control motor 2 19. The start of the control motor will then drive the worm 21 on the outer wall of the transmission shaft 20 to rotate. This design allows medical staff to better observe and analyze lesions by adjusting the angle and speed of the worm 21. In addition, the rotation of the worm 21 can further drive the worm wheel 22 to rotate. This design allows medical staff to control the equipment more accurately during operation. At the same time, the rotation of the worm wheel 22 will also drive the adjustment screw 23 to rotate, thereby realizing the lifting and lowering control of the support column 15. This design allows medical staff to conveniently adjust the height of the colposcope according to specific needs to obtain a better observation angle. The support column 15 is limited and lifted under the constraint of the outer wall of the limit rod 24. This design not only ensures the stability of medical staff during operation, but also avoids observation errors caused by the height instability of the equipment. At the same time, the support column 15 can flexibly adjust its position during the lifting and lowering process of the inner wall of the sleeve 16, so that medical staff can easily use the colposcope in different scenarios.

[0035] Working principle: when the optical colposcope is needed to observe the lesion, firstly, by pressing the adjustment button 2 14 on the outer wall side of the handle 12, a signal is sent to start the control motor 2 19, thereby achieving the effect of driving the worm 21 on the outer wall of the transmission shaft 20 to rotate, and the rotation of the worm 21 further drives the worm wheel 22 to rotate, and the worm wheel 22 drives the adjustment screw 23 to rotate, and at the same time, the support column 15 can be limited and lifted on the outer wall of the limit rod 24, and the support column 15 is lifted and lowered on the inner wall of the sleeve 16, so as to achieve the effect of facilitating the adjustment of the height according to the specific use needs of medical staff;

[0036] Secondly, when the main mirror 6 of the microscope reaches the lesion, the support plate 5 can be rotated on the outer wall of the adjusting bolt 401 by rotating the adjusting nut 402, thereby achieving the effect of facilitating the adjustment of the angle of the support plate 5. At this time, by pressing the adjusting button 13 on the upper side of the handle 12, a signal for starting the control motor 10 is sent. At this time, after the motor 10 is started, the adjusting gear 11 is driven to rotate, thereby achieving the effect of facilitating the engagement and rotation of the focusing knob 8. By rotating the focusing knob 8, the focal length of the main mirror 6 of the microscope is easily adjusted. By pressing the adjusting button 13 on the lower side of the handle 12, the opposite focal length of the main mirror 6 of the microscope is further adjusted.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
