New description: [New technical field] The creation department provides a kind of telescopic telescope, especially a telescopic method to adjust the focal length between optical lenses to achieve the best: telescope. Main [Prior Art] De f telescope uses optical lenses to properly magnify the image of the target, :, , , , and when observing, the user must first adjust the telescope to the appropriate focal length to get the best and most Clear image effects. The fields that Tianwang Mirror can be applied are quite extensive. Military reconnaissance, animal and plant observation, and astronomical astrology can all be observed by telescope. However, in addition to providing observers with the naked eye, the dawn of light and technology Thanks to the development, the telescope can also be equipped with a digital camera or a video camera, etc., which can simultaneously record the target object while the observation is being made, and store the recorded image information in the light ^ The storage medium 'minus' can completely access the important image tfL to avoid the need to refer to the first figure. The conventional telescopic telescope includes a fixed lens barrel 1 a, a telescopic lens barrel 2 a and a The image transfer structure 3 a is provided with an optical main lens assembly worker a in the fixed lens barrel 1 a. The telescopic lens barrel 2a is provided with an optical correction lens group 2 ia. The telescopic lens barrel 2 a is telescopically disposed on the inner edge of the fixed lens barrel ia. The shadow structure 3 a is disposed on the telescopic lens barrel 2 . One end of a is used to connect the device. Thus, when the user wants to adjust the optical main lens group i i a and the light M343168 = the focal length of the lens group 2 1 a, it is only necessary to move the telescopic lens barrel to adjust to the optimal focal length. 7 The camera is in the image-converting structure 3 3 ^ Mounting the digital camera-specific image-taking device... Because the image-taking device itself has a fixed weight, this: the weight will be provided with the image transfer structure 3 in the telescopic lens barrel 2a. The bending moment of a-钿 is generated, so that the cylinder of the telescopic lens barrel 2 3 causes the shift of the optical main lens group 11 a and the light correction lens group 2 1 a, and cannot Get the most accurate focal length. The reason is that this creator feels that the above-mentioned deficiencies can be improved, and that he has devoted himself to researching and applying the application of theory, and finally expects to describe the lack of creation. $高善上 [New content] The main purpose of this creation is to provide a telescopic telescope. When the user mounts the image capture device such as a digital camera on the image transfer structure, it will not be because of the weight of the image. The bending moment effect on the end of the telescope can keep the telescope barrel straight, thus maintaining the accuracy of the focus adjustment. In order to achieve the above purpose, the present invention provides a telescopic telescope, which comprises: a fixed lens barrel in which an optical correcting lens group is disposed; and a telescopic lens barrel which is telescopically disposed on an inner edge of the fixed lens barrel. An optical main lens group is disposed in the lens barrel corresponding to the optical correction lens group; and an image transfer structure is disposed at one end of the fixed lens barrel and disposed corresponding to the optical correction lens group and the optical main lens group. ^The authoring system has the following beneficial effects: by slanting the image transfer structure on the __ end of the fixed lens barrel, when the user mounts the image capturing device such as a digital camera on the image transfer structure, Because of the weight of the image capture device, M343168, because the diameter of the lens barrel is smaller than that of the telescopic mirror, the material can be cut straight or the main lens is fine. LI, _, ▲ μ... Large = ί lens group diameter 'So, the optical correction lens group can: face by: the light projected by the optical main lens group, and reduce the phenomenon of image distortion. In order to further understand the characteristics and technical content of this creation, please refer to the following detailed description and schema of this creation. However, the drawings are only for McCaw and description, and are not used to limit this creation. By. /, [Embodiment] Please refer to the second and third figures for the creation of the telescopic telescopic mirror. 'It includes: - solid ^ lens tube! - Telescopic tube 2 and - Shadow structure 3. The fixed lens barrel 1 is a hollow circular cylindrical structure. The image transfer structure 3 is disposed at one end of the fixed lens barrel and is disposed corresponding to the optical lens group 1 1 and the optical field group 21 described later. In order to achieve the effect of polyphonic development. The fixed lens barrel i is provided with an optical correction lens assembly and an adjustment seat 12, and the optical correction lens assembly is disposed at an inner edge of the fixed lens barrel 1 adjacent to the image transfer structure 3, the adjustment seat i 2 It is fixed to the other end of the fixed barrel 1. The adjusting seat 1 2 is provided with an adjusting roller set i 2 i and a focal length display 122. The adjusting roller set ι21 has a gear 12 working 0, a coarse adjusting roller 1 2 1 1 and a fine adjusting roller 1 2 1 2, which The M343168 gear 1210 is disposed at a lower end of the adjusting base 12 and is connected to the coarse adjusting roller 1 21 1 and the fine adjusting roller 1 2 1 2 . The diameter of the coarse adjustment roller 1 2 1 1 is larger than that of the fine adjustment roller 1 2 1 2 , and the fine adjustment roller 1 2 1 2 is disposed outside the coarse adjustment roller 1 2 1 1 . The focal length display 1 2 2 is disposed at an upper end of the adjusting base 12, and the focal length display 1 2 2 can electromagnetically sense the displacement of the extension-retracting mirror 2 in the fixed barrel 1 and display The data is at the focus, - from the display 1 22, to facilitate the user to adjust the focal length. The telescopic lens barrel 2 is telescopically disposed on the inner edge of the fixed lens barrel 1. The telescopic lens barrel 2 is provided with an optical main lens group 21 and a rack 2 2, and the optical main lens group 21 corresponds to the optical correction lens group. 11 is disposed in the telescopic barrel 2. The rack 2 2 is disposed at a lower end of the telescopic barrel 2 corresponding to the gear 1 2 1 , and the rack 2 2 is engaged with the gear 1 2 1 0. In this way, when the user wants to make the telescopic lens barrel 2 to perform a large displacement, since the coarse adjustment roller 1 21 1 has a large diameter, the user can rotate the coarse adjustment roller 1 2 1 1 by fingers. The telescopic barrel 2 is subjected to a large-scale telescopic displacement operation. Conversely, if the user wants to fine-tune the focal length, the rotation adjustment roller 1 2 1 2 can be rotated a little, thereby an adjustment operation, and the user can obtain the most The ideal focal length. As shown in the fourth figure, the image capturing device 4 can be further disposed on the image transfer structure 3, and the image capturing device 4 can be a digital camera or a digital camera, and The lens can receive the image of the optical correcting lens group 1 i and the optical main lens group 2; and can simultaneously perform image recording operations synchronously. 8 M343168, the functions and features that can be produced by this creation are as follows. By setting the image transfer structure 3 to use ί on the image transfer structure 3 mount number = clothing f 4, not because of image capture (4) The weight of the fixed = two should 'stay the fixed lens barrel 1 and the telescopic barrel 2 - body straight straight' to maintain the accuracy of the focus adjustment.
