DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0023] like Figure 1-Figure 4 As shown, a magnifier convenient for external connection comprises a magnifier body 1 and an external connection structure 5. The magnifier body 1 is a cylindrical cavity structure with openings at both ends. An eyepiece 4, a prism 8 and an objective lens 12 are arranged in sequence from right to left inside the magnifier body 1. The eyepiece 4 is connected to the inner wall of the magnifier body 1 through an eyepiece frame, the prism 8 is connected to the inner wall of the magnifier body 1 through a prism seat 7, and the objective lens 12 is connected to the inner wall of the magnifier body 1 through an objective lens frame 11; the magnifier body 1 is provided with an eye mask 14 at one end, and an external structure 5 is provided at the other end of the magnifier body 1; the external structure 5 includes a first connecting ring 501, a second connecting ring 506, a fixing ring 507 and a driving mechanism, the second connecting ring 506 is sleeved on the first connecting ring 501, two fixing rings 507 are provided inside the second connecting ring 506, one end of the fixing ring 507 is movably connected to the first connecting ring 501, and the fixing ring 507 is connected to the driving mechanism in the second connecting ring 506.

[0024] It should be noted that the main function of the magnifier is to significantly enhance the magnification effect of the observed target, making the details that were originally unclear or difficult to distinguish become clearly visible, which is helpful for observing and studying tiny objects and fine structures. Based on this, we designed a magnifier that can be used alone as a telescope, or combined with an optical instrument such as a telescope to improve clarity. Therefore, we set up structures such as an eyepiece 4, a prism 8 and an objective lens 12 inside the magnifier body 1. The eyepiece 4 can further magnify the image formed by the objective lens, so that the observer can see the details more clearly, and the final image presented is corrected and optimized to provide a better visual effect; the role of the prism 8 is to change the propagation direction of the light, so that the light is transmitted and refracted according to the designed path to achieve a specific optical effect, and cooperate with the objective lens 12 to perform the initial magnification imaging of the target object, and obtain a clear image of the object from the optical system, thereby achieving an enhanced magnification effect of the observed target.

[0025] It needs to be further explained that during the use of the magnifier, we often connect it with other optical instruments. Since the connection port of the magnifier and the connection port of other optical instruments are not unified, the specifications and diameters are different, and it is not easy to connect them. Based on this, we designed an external structure 5, including a first connecting ring 501 and a second connecting ring 506. The first connecting ring 501 is connected to the magnifier, and the second connecting ring 506 is connected to other optical instruments through an internal fixing ring 507. In addition, we use two symmetrically arranged fixing rings 507, which are driven close to each other by screws to facilitate connection with optical instruments of different diameters.

[0026] like Figure 2-Figure 4 As shown, the driving mechanism includes a driving box 502, a rotating box 503, a first connecting rod 512, a screw 513, a nut 514, a first gear 515, a second gear 516 and a rotating handle 517. The driving box 502 and the rotating box 503 are arranged on the second connecting ring 506. A screw 513 is arranged inside the driving box 502, and a nut 514 is arranged on the screw 513. The nut 514 is movably connected to the connecting shaft on the fixed ring 507 through the first connecting rod 512; a first gear 515 is arranged on the upper part of the screw 513, and the first gear 515 is meshed and connected with the second gear 516 on the rotating shaft 519 inside the rotating box 503, and one end of the rotating shaft 519 is connected to the rotating handle 517.

[0027] It should be noted that, in order to enable the two fixing rings 507 to be opened and retracted, the two fixing rings 507 are movably connected to the nut 514 on the screw rod 513 through the first connecting rod 512. When the screw rod 513 rotates, the nut 514 moves laterally. During the movement, the two fixing rings 507 are closed, thereby connecting with the connecting port on the optical instrument.

[0028] It should be further explained that, in order to ensure the tightness of the connection, we set a limiting ring 518 on the inner wall of the two fixing rings 507, and the limiting ring 518 is a rubber ring to facilitate the fixation of the fixing ring 507.

[0029] It should be further explained that, for the convenience of driving, a second gear 516 is provided inside the rotating box 503, and it is rotated by turning the handle 517, and the second gear 516 is meshedly connected with the first gear 515, and the rotation of the first gear 515 drives the screw 513 to rotate, thereby realizing the driving of the nut 514, and the ratio of the second gear 516 and the first gear 515 can be replaced as needed.

[0030] like Figure 2-Figure 4 As shown, the fixing ring 507 is a semi-arc structure with openings at both ends. A connecting block 510 is provided at one end of the fixing ring 507. The fixing ear 509 of the connecting block 510 is movably connected to the rotating shaft on the first connecting ring 501. The rotating shaft is provided on the connecting plate 508 of the first connecting ring 501. A plurality of limiting rings 518 are provided inside the fixing ring 507.

[0031] It should be noted that the fixing ring 507 is used as a connecting ring for docking and fixing with other optical instruments. In order to adapt to different docking port diameters, we adopt a structure of two fixing rings 507, which are driven by a driving mechanism so that the two fixing rings 507 cover and fix the connection. The entire fixing ring 507 can be driven by the driving mechanism and can be opened and closed based on the angle on the rotating axis of the first connecting ring 501, thereby achieving fixation and opening, which is convenient for operators to disassemble.

[0032] like Figure 1 As shown, at least three eyepieces 4 are provided, a shading sheet 9 is provided in the middle of the two prisms 8; an eyepiece spacer 2 is provided between the two eyepieces 4, and a handwheel pressure ring 3 is provided outside the eyepiece spacer 2; a retaining ring 10 is provided at the connection between the objective lens frame 11 and the magnifier body 1.

[0033] It should be noted that we have set up eyepieces, prisms and objective lenses inside the main body of the magnifying lens, which can significantly enhance the magnification effect of the observed target, making the details that were originally unclear or difficult to distinguish clearly visible, which is helpful for the observation and research of tiny objects and fine structures.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
