Description of the invention: [Technical field to which the invention pertains] The present invention relates to a type of telescope (four), a device, and more particularly, a type of eyepiece and a line of sight can be adjusted when focusing is adjusted. Focusing device for telescopes with accuracy. [Prior Art] Press, the telescope is provided with a polysilicon to adjust the focal length with the distance of the observation object. As far as the structure of the poly-domain of the telescope is concerned, as far as the first-to-picture structure is concerned, the structure has not been improved for a long time, and the inside of the front end of the lens barrel W of the telescope is embedded with an eyepiece U, and the eyepiece is connected. An eyepiece 12 is fixed to the front end of the crucible. The combination of the lens barrel 1〇 and the eyepiece tube u is provided with a rack 110 on the bottom side of the eyepiece tube ^, and the bottom end of the lens barrel 1G is provided with a gear rack corresponding to the rack 11G (as shown in the second figure), the gear The wheel 101, which is received by the outside of the lens barrel 10, is driven to rotate in place. As the apparatus adjusts the distance of the object, the gear 1 can drive the gear 1 to drive the rack 11 forward or backward, and the eyepiece 11 and the eyepiece 12 are synchronously displaced. Although the conventional focusing device can drive the eyepiece to connect the g 11 and the eyepiece 12 for the front and rear displacement to adjust the focal length, there is a lack of focal length adjustment inaccurate, because the focus is accurate and the telescope and the eyepiece should be used. Whether the axis lines A and B overlap are on the same line. However, the meshing position between the eyepiece U and the gear 1 is located below the axis B of the telescope axis A and the eyepiece ,2, that is, the eyepiece is connected.] 1285274 and the gear 1GG are mixed. The heart line Α, β below, 峨, when the gear (10) is rotated forward (as shown in the second figure), or backwards is difficult ^ as shown in the third figure), the axis of the eyepiece, the system Will be biased and the axis of the telescope does not overlap, not on the same -, so, lost the quasi-heterogeneous. SUMMARY OF THE INVENTION The present inventors have made improvements in design in view of the fact that the focusing device of the conventional telescope has the above-mentioned missing in use, and the present invention has been produced. The main objective of the present invention is to provide a focusing device for a telescope that adjusts the accuracy of the axis of the eyepiece for a focus adjustment. The main feature of the present invention is that the eyepiece _- faces the fixed eyepiece, and the other end is fixed with a poly-domain of the outer wall with the external thread, and the axis line of the poly-language and the eyepiece is on the same-line, and is limited by the orientation group. It can only be used for axial displacement; it has a focusing ring, and the inner part has internal thread for the focusing cylinder to pass through. If the line is the same as the focusing tube, the limit can be axially displaced in the original drive = poly = cylinder. With these settings, the focus cylinder is driven by the focus ring to drive the displacement. The inflammatory cylinder is axially oriented. If the line is unchanged, the axis of the eyepiece and the axis of the telescope are maintained, and the position side is on the straight line.俾 (4), adjust the accuracy. [Embodiment] The present invention is directed to the technical means for achieving the above objects and features. Referring to Figures 4 and 5, the focusing device of the present invention comprises: 1285274 A simplified body 20, one end attached to a telescope The lens barrel 30 is fixed, A is hollow, and the inner wall of the 3⁄4 end has a bolt fixing hole (such as the fifth figure). The middle body is another one body 40' is arranged in a circular shape. A hole 42 is formed in the wall surface of the hole 41. The bolt 42 passes through the through hole 42 between the dam and the cylinder 20, and is then locked with the fixing hole 21 of the cylinder 20 to fix the body 40 and the cylinder 20. A plurality of binding columns 44 protrude from the inner side near the outer side of the body 4〇, and the inner side wall of the body 40 between the column private and the sample hole 41 has a placement platform 45 (as shown in the sixth figure). The surface of the cymbal placement platform 45 protrudes from a plurality of circularly arranged arcuate faces. - The fixed washer 50 is in the shape of a hollow disc, and is embedded in each of the arcuate faces 450 of the body 4 〇 0 and has a plurality of perforations 51 on the surface. The mouth-orientation ring 60 (ie, the orientation group, see the fifth and sixth figures) is in the shape of a *, located on the inner side of the body 40, and the outer side protrudes from the outer lip 6 to the outer lip & The coupling post 44 has a coupling hole 62 which is fitted to each other with the coupling post 44 of the coupling hole 62 = 40 to be fitted to each other, and the inner wall is recessed by a plurality of axially oriented directional grooves 63. Two-focus ring 70 (please refer to the fifth and sixth figures), located on the outer body 4〇 7^ face = threaded, facing the body 40 end with a thin neck 7 pad neck 71 end face fixed Huasi 5 〇 perforation; 2: 固司 50 ΪΪϋ ΪΪϋ ΪΪϋ 〇 〇 〇 螺 螺 72 72 72 72 72 72 72 72 72 72 72 72 72 螺 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦 聚焦Jiao 1: (4? 参 =, 1), is a hollow circular shape, one end is provided with an external thread through the upper part, and the arcing surface 82 is formed outside the fn, and the arcuate surface 82 drives the focusing cylinder 80 to make an axial shift ,,. The inner thread of the garment is screwed so that the focus ring 70 can be 6 1285274 s and the collet condensate 92 (as shown in the fifth figure). 81 screwing mutual thread 91G'俾 and poly' series 8G inner thread thread 91丨 end face ^ wheel Gushuo the other end of the root also has external thread 911, outer = wall axis eye to face the face of the master clip 912 The clip 912 is clamped and fixed. As long as the forward direction: as shown in the six figures, 'when the focal length is to be adjusted', the internal thread of the cylinder 8 〇 arc surface 82 and the 2 2 focal ring 70 can drive the focus 8 〇 consolidation - the body of the m + _ 〇 Displacement, and make the focus with the focus tube - iF = two mirrors, that is, the accuracy of the focus adjustment, there will be no error (such as the heart, seven figure eight figure S for the displacement of the group structure can also For example:::ϊί^ 可定ϊίϋ83 'For the focusing cylinder 80 to extend into the orientation ring 60, the guide post 64 rotates.
