[0032] In the following description, examples are provided to provide a deeper understanding of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. It should be understood that the specific embodiments described are only for the purpose of explaining the present invention and are not intended to limit the present invention.

[0033] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or combinations thereof.

[0034] In order to solve the above technical problems, the present application provides an electron microscope that supports stepless zoom. Figure 1 To the attached Figure 7, including a first base body 1, a lens group 2 and a first adjustment sleeve 3, one end of the first base body 1 is provided with a guide column 11, and a view hole that avoids the guide column 11 to connect the two ends; the lens group 2 is provided with a movable ear 21, the movable ear 21 is slidably sleeved on the guide column 11, and the outer side of the movable ear 21 is provided with a first protrusion 22; the lens group 2 is accommodated in the first adjustment sleeve 3, and the first protrusion 22 slides in the first sliding track 31 on the inner wall of the first adjustment sleeve 3; it also includes a second base body 4, a second adjustment sleeve 5, a chip board 6 and a display, the second base body 4 is rotatably connected to the first adjustment sleeve 3 One end away from the first base body 1; the second adjusting sleeve 5 is rotatably connected to the end of the second base body 4 away from the first adjusting sleeve 3; the inner wall of the second adjusting sleeve 5 is provided with a second sliding track; the chip board 6 is equipped with an image sensor, and second protrusions 61 are provided on both sides of the edge; the chip board 6 is accommodated in the second adjusting sleeve 5, and the second protrusion 61 slides in the second sliding track; the display screen 7 is connected to the chip board 6 for displaying the target image; it is worth noting that the first adjusting sleeve 3 and the second adjusting sleeve 5 have the same structural features, so only the independent view of the first adjusting sleeve 3 is given, that is, the attached Figure 7 ;

[0035] The specific steps of the present application are as follows: the user first rotates the first adjusting sleeve 3, and the first protrusion 22 cooperates with the first sliding track 31, so that the lens group 2 follows the rotation of the first adjusting sleeve 3 and slides back and forth in the axial direction of the guide rail, so that the lens group 2 reaches the first position, and the above-mentioned reciprocating sliding can adjust the optical front focus and back focus; then, by continuing to rotate the second adjusting sleeve 5, the second protrusion 61 cooperates with the second sliding track, so that the chip board 6 and the second adjusting sleeve 5 continue to rotate back and forth in the axial direction of the guide rail. When the chip board 6 reaches the second position that matches the first position, optical focus is achieved, and the target image can be obtained on the display screen 7; the second base body 4 can prevent the first adjusting sleeve 3 from moving, thereby enhancing the stability of the adjustment;

[0036] By rotating the first adjusting sleeve 3 and the second adjusting sleeve 5 to adjust the reciprocating movement of the two optical imaging structures of the lens group 2 and the chip board 6, the zoom function is realized, and with the cooperation of the bumps and the sliding track, the overall zoom action is smooth and there is no obvious sense of jamming, so that users can get a better user experience.

[0037] In this embodiment, the first base body 1 is provided with a first sleeve 12 at one end of the guide column 11. The cylindrical surface of the first sleeve 12 is provided with a first hole, and the first protrusion 22 is connected to the first sliding track 31 through the first hole. It is not difficult to understand that the first adjustment sleeve 3 is fitted on the first sleeve 12 so that the axes of the first base body 1 and the second adjustment sleeve 5 can coincide, so that the first adjustment sleeve 3 does not deviate during the rotation process, and the rotation is more stable. The first hole can form a reasonable avoidance structure, so that the linear sliding of the lens group 2 is more stable. It can be seen that the addition of the first sleeve 12 can better drive the lens group 2 to slide.

[0038] In this embodiment, a second cylinder 41 is further provided at the end of the second base body 4 away from the first adjusting sleeve 3, and a second hole is opened on the cylindrical surface of the second cylinder 41, and the second protrusion 61 is connected to the second sliding track through the second hole; the second cylinder 41 has similar functions and mechanisms to the first cylinder 12, and can enable the second adjusting sleeve 5 to obtain the same working effect as the first adjusting sleeve 3. Based on the above records, it will not be repeated here.

[0039] In this embodiment, the first sliding rail 31 can be realized by a magnetic slide rail, a mechanical slide rail, etc. In a better solution, the first sliding rail 31 and the second sliding rail are thread grooves. The structure of the thread groove is simple and the forming process is relatively mature. It can effectively save processing costs while maintaining reasonable coordination with the first protrusion 22 and the second protrusion 61.

[0040] In this embodiment, a third seat body 8 is also included, one end of the third seat body 8 is connected to the second adjusting sleeve 5 to limit the movement of the second adjusting sleeve 5, and the other end is connected to the display screen 7; by being connected to the display screen 7 in the third state, the difficulty of assembly with the display screen 7 can be significantly reduced, and it can ensure that the first adjusting sleeve 3 will not move, so that the second adjusting sleeve 5 and the first seat body 1 have better concentricity, which is convenient for users to use and avoids jamming.

[0041] In this embodiment, the cylindrical surfaces of the first adjustment sleeve 3 and the second adjustment sleeve 5 are both provided with a force-carrying portion; the force-carrying portion can significantly increase the gripping resistance during rotation and prevent the user's hand from slipping.

[0042] In this embodiment, a data interface 71 is further provided on one side of the display screen 7. The data interface 71 can output images for further use by the user.

[0043] The advantages of this utility model are:

[0044] By rotating the first adjustment sleeve and the second adjustment sleeve to adjust the reciprocating movement of the two optical imaging structures of the lens group and the chip board, the zoom function is realized. Thanks to the cooperation of the bumps and the sliding track, the overall zoom action is smooth and there is no obvious sense of jamming, so that users can get a better user experience.

[0045] The above disclosures are only a few specific embodiments of the present invention, but the present invention is not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
