[0030] In particular, the above eyepiece mounting unit (200) performs the role of enabling the mounting of one end of an eyepiece having various specifications (diameters).

[0031] As shown in FIG. 3, the eyepiece mounting unit (200) comprises: a body (210) having a plurality of first guide grooves (211) on the front surface that gradually tilt toward one side as they go from the inside to the outside, a radially formed insertion groove (212) on the rear surface, and a radially formed locking projection (213) on the inside of the insertion groove (212); and a plurality of first joining parts (220) formed radially with respect to the center of the body (210), having a first guide shaft (222) formed on the rear surface to be inserted into the first guide groove (211), a second guide shaft (221) formed on the front surface, and insertion grooves (223) on both sides. A plurality of second joints (230) are arranged radially with respect to the center of the body (210), positioned in front of the first joint (220), with a third guide shaft (232) formed so that it can be inserted into the first guide groove (211) by penetrating the insertion groove (223) at the rear, a fourth guide shaft (231) formed at the front, and insertion grooves (233) provided on both sides so that the second guide shaft (221) can penetrate; It includes a first cover (240) formed to be mounted on the front of the body (210) so as to be rotatable, having a through hole in the center, and having a plurality of adjustment grooves (241) formed on the front surface such that they gradually tilt in the opposite direction to the first guide groove (211) from the inside to the outside, and arranged so that the second guide shaft (221) and the fourth guide shaft (231) can be inserted into the inner side of the adjustment groove (241).

[0032] In particular, the body (210) is formed in a circular shape and mounted so that the first cover (240) can rotate freely at the front.

[0033] At this time, the center of the body (210) is formed in a hollow shape to minimize weight and allow one end of the eyepiece to be inserted.

[0034] In the present invention, the first guide groove (211) is formed radially in multiple numbers such that, when viewed from the front, it gradually tilts toward one side or the other as it moves from the inner side to the outer side of the body (210).

[0035] In particular, the first guide groove (211) is formed with a certain width and length, as well as a straight line or an arc shape, so that when the first cover (240) rotates, the positions of the plurality of first joining parts (220) and second joining parts (230) can move outward or inward, thereby guiding them to expand or contract.

[0036] In addition, the insertion groove (212) is formed to have a certain width so that the mounting jaw (331) of the length adjustment unit (300) can be inserted inwardly, and the locking jaw (213) comes into contact with each other and fixes when the user rotates the length adjustment unit (300) to one side while the mounting jaw (331) is inserted into the insertion groove (212), and when the length adjustment unit (300) is rotated in the opposite direction, the mounting jaw (331) and the locking jaw (213) separate from each other, allowing the eyepiece mounting unit (200) and the length adjustment unit (300) to be detached.

[0037] Meanwhile, the first joining part (220) and the second joining part (230) are block-shaped, forming an outer diameter and an inner diameter, and can adjust the size (diameter) of the inner diameter by moving outward or inward so as to be applied to the specifications of one end of the eyepiece.

[0038] These first joint (220) and second joint (230) are formed in a plurality radially around the center of the body (210) when viewed from the front.

[0039] At this time, the first joining part (220) and the second joining part (230) can be formed from various materials such as synthetic resin or silicone to securely fix one end of the eyepiece.

[0040] In addition, a reinforcing part (234) formed to have a certain length in front of the second joint part (230) can be included to firmly support and fix one end of the eyepiece.

[0041] In addition, the plurality of first joint parts (220) and second joint parts (230) are arranged so that their centers are staggered from each other when viewed from the front, thereby allowing the first guide shaft (222), second guide shaft (221), third guide shaft (232), and fourth guide shaft (231) to be inserted into the inner side of the first guide groove (211) and the adjustment groove (241) respectively without interference from each other.

[0042] Here, the first guide shaft (222) and the third guide shaft (232) are inserted into the inner side of the first guide groove (211), and the second guide shaft (221) and the fourth guide shaft (231) are inserted into the inner side of the adjustment groove (241) so that they can move according to the rotational direction of the first cover (240).

[0043] In particular, the above-mentioned insertion grooves (223, 233) are formed to have a certain width and height so that the first guide shaft (222), the second guide shaft (221), the third guide shaft (232), and the fourth guide shaft (231) can pass through without interference.

[0044] Additionally, the first cover (240) can simultaneously rotate the adjustment groove (241) according to the angle and direction in which the user rotates it, thereby moving a plurality of the first joining parts (220) and second joining parts (230) inward or outward.

[0045] Here, the adjustment groove (241) is formed radially so that as it moves from the inside to the outside, it gradually tilts in the opposite direction to the first guide groove (211).

[0046] At this time, it is preferable that the adjustment groove (241) be formed to have the same shape and number as the first guide groove (211).

[0047] Meanwhile, it may include a fastening hole (214) formed on the front outer surface of the body (210); an elongated hole (242) formed on the outer surface of the first cover (240) to have a certain length; and a fastening member (243) formed to penetrate the elongated hole (242) and be coupled with the fastening hole (214).

[0048] That is, by rotating the fastener (243) to connect or disconnect it from the fastener hole (214), the first cover (240) can be rotated and fixed at a designated position and angle.

[0049] Here, the above-mentioned elongated hole (242) is formed to have a certain length according to the radius of rotation of the first cover (240), and the above-mentioned fastener (243) can be screw-coupled with the above-mentioned fastener (214) using a bolt or screw.

[0050] Accordingly, as shown in FIG. 8, the eyepiece mounting unit (200) maintains a state in which the first guide shaft (222) and the second guide shaft (221) of the first joining part (220) and the third guide shaft (232) and the fourth guide shaft (231) of the second joining part (230) are alternately inserted into the inner lower portions of the plurality of first guide grooves (211) and adjustment grooves (241).

[0051] That is, since the first joint part (220) and the second joint part (230) are arranged to be staggered from each other, the first guide shaft (222) and the second guide shaft (221), and the third guide shaft (232) and the fourth guide shaft (231) can be positioned without interference in the inner lower part of the plurality of first guide grooves (211) and adjustment grooves (241).

[0052] Next, as illustrated in FIGS. 9 and 10, when the user rotates the body (210) and the first cover (240) in opposite directions, the first guide shaft (222) and the second guide shaft (221), and the third guide shaft (232) and the fourth guide shaft (231) move outward along the first guide shaft (211) and the adjustment groove (241) according to the rotational position of the first guide groove (211) and the adjustment groove (241), and simultaneously move a plurality of the first joining parts (220) and the second joining parts (230) outward, thereby allowing the size of the inner diameter to be adjusted according to the specifications of one end of the eyepiece.

[0053] In the present invention, the length adjustment unit (300) performs the role of adjusting the length according to the distance between one end of the eyepiece and the eyepiece of the astronomical telescope.

It includes a second mounting member (340) mounted at the rear of the length adjustment member (320) and having a mounting projection (341) formed radially on the outer side.

[0055] In particular, the above-mentioned cylinder (310) is a hollow shape with an empty interior, and the length adjustment member (320) is inserted into the interior so that it can move along the longitudinal direction.

[0056] In addition, the guide groove (311) and the guide projection (321) are in contact with each other so as not to shake or detach during the process of the length adjustment member (320) moving in the longitudinal direction.

[0057] And the first gear (312) and the second gear (322) use a rack and pinion gear, so that when the user rotates the handle (314), the first gear (312) rotates simultaneously, converting the meshed second gear (322) into linear motion to move the length adjustment member (320) and adjust the length of the length adjustment unit (300).

[0058] Meanwhile, the mounting jaw (331) can be rotated through the insertion groove (212) of the eyepiece mounting unit (200) to engage with the locking jaw (213), thereby fixing or separating the eyepiece mounting unit (200) and the length adjustment unit (300) from each other.

[0059] And the mounting jaw (341) can be rotated by passing through the insertion groove (411) of the angle guide (400) to engage with the mounting jaw (413), thereby fixing or separating the length adjustment unit (300) and the angle guide (400) from each other.

[0060] Here, the first mounting member (330) is mounted to the front of the cylinder (310) so as to be able to rotate freely, and the second mounting member (340) is mounted to the rear of the length adjustment member (320) so as to be able to rotate freely, allowing the user to rotate each for attachment and detachment.

[0069] At this time, the center of the body (510) is formed in a hollow shape to minimize weight and allow the eyepiece of the astronomical telescope to be inserted.

[0070] In the present invention, the first guide groove (511) is formed radially in multiple numbers such that, when viewed from the front, it gradually tilts toward one side or the other as it moves from the inner side to the outer side of the body (510).

[0071] In particular, the first guide groove (511) is formed with a certain width and length, as well as a straight line or an arc shape, so that when the second cover (540) rotates, the positions of the plurality of first joining parts (520) and second joining parts (530) can move outward or inward, thereby guiding them to expand or contract.
