Description

Technical Field

[0001] This utility model relates to an optical magnification device, and more particularly to a high-stability high-resolution telescope. Background Technology

[0002] Children are prone to nearsightedness or poor posture due to prolonged close-range reading or mobile phone use. Therefore, in order to avoid excessive eye strain or neck and shoulder pain, optical magnification devices are used to reduce eye strain and correct posture.

[0003] The high-angle zoom lens created by the applicant in this case and obtained Taiwan Utility Model Patent No. M656366 uses an optical path constructed by a magnifying lens and a reflecting lens that are angled together, allowing users to read at an appropriate distance of 30 to 50 centimeters, thus avoiding the problems of close-range reading and neck and shoulder pain.

[0004] When using the aforementioned high-powered telephoto lens, the magnifying lens or the reflecting lens may wobble due to the weight of the mount, thus affecting stability. Therefore, the applicant, with a spirit of continuous improvement, conducted in-depth research and made improvements to address the wobble issue, thus completing this work. Utility Model Content

[0005] The purpose of this invention is to provide a high-stability telescope.

[0006] The high-stability telephoto lens of this invention includes a support unit, a lens mount unit, and at least one support unit.

[0007] The support unit includes a support arm. The lens mount unit is disposed on the support arm and includes a first lens mount and a second lens mount connected to one side of the first lens mount. The first lens mount has a first base and a first lens. The second lens mount has a second base and a second lens. The second base has at least one through-slot spaced from the second lens. The through-slot extends through the front and rear sides in a front-rear direction. The at least one support unit is disposed on the lens mount unit and is used to support the first lens mount and the second lens mount in an open state. The at least one support unit includes a support rod, a bearing, and a movable sleeve. The support rod is movably inserted through the through-slot of the second lens mount and has a first end and a second end disposed opposite to each other. The first end is pivotally mounted on the first base. The bearing is disposed on the second end of the support rod. The movable sleeve allows the support rod to movably insert through and pivotally mount on the through-slot of the second base. When the first mirror mount and the second mirror mount are in the open state, the bearing moves with the second end of the support rod and enters and locks into the movable sleeve, thereby locking the movable sleeve, and the support rod is supported between the first mirror mount and the second mirror mount.

[0008] This utility model discloses a high-stability telephoto lens. The first lens mount can be flipped relative to the second lens mount to a closed state, and the at least one support unit can move relative to the second mount body between a supported position and an unsupported position. In the supported position, the at least one support unit supports the first lens mount and the second lens mount in the open state, and the first end of the support rod is higher than the second end and away from the second lens mount. In the unsupported position, the first lens mount is flipped relative to the second lens mount to the closed state, and the first end of the support rod is lower than the second end and adjacent to the second lens mount. The second end of the support rod drives the shaft seat away from the through slot and disengages from the movable sleeve.

[0009] The high-stability telephoto lens of this utility model includes a movable sleeve with a through groove in the second base body extending in the left-right direction, a movable sleeve that is pivotally mounted on the shaft and allows the support rod and the base to move through it, and a pin that moves through the movable sleeve in the left-right direction. When the at least one support unit is in the supported position, the pin locks the base so that it cannot move relative to the movable sleeve. When the at least one support unit is in the unsupported position, the pin disengages from the base.

[0010] The high-stability telephoto lens of this invention includes a movable sleeve with a sleeve hole for the support rod to pass through, and a radial through hole extending vertically from the outer surface to the sleeve hole. The pin is movably disposed in the radial through hole. The bearing has a circumferentially surrounding concave annular groove for the pin to extend into, and a tapered section connecting the concave annular groove. The movable sleeve also has an elastic element that constantly pushes the pin to move toward the sleeve hole. When the at least one support unit moves between the supported position and the unsupported position, the pin is pushed by the tapered section and moves away from the sleeve hole, thereby causing the elastic element to undergo elastic deformation.

[0011] The high-stability telephoto lens of this utility model has a movable sleeve that also has a backing wall, a peripheral wall surrounding the backing wall, and a hanging part disposed on the peripheral wall for the shaft to pass through. The sleeve hole is defined by the backing wall and the peripheral wall. The groove of the second base has a long opening on the front side and a rear opening opposite to the long opening in the front-rear direction. The size of the long opening is smaller than the size of the backing wall.

[0012] The high-stability telephoto lens of this utility model has a movable sleeve of at least one support unit, which also has a positioning hole formed on the peripheral wall and two protrusions spaced apart on the peripheral wall. The radial through hole is located between the protrusions. The elastic element is a spring sheet with one end fixed to the positioning hole and the other end abutting against the pin.

[0013] The high-stability telephoto lens of this invention also includes a washer in the movable assembly for frictional movement of the support rod.

[0014] The high-stability telephoto lens of this invention has a second end of the support rod with an external thread, and the bearing seat of at least one support unit is rotatably screwed to the external thread of the support rod.

[0015] The high-stability telephoto lens of this utility model has a base portion and a rod portion that is smaller than the base portion and extends outward from the base portion. When the first lens base and the second lens base are supported in the open state, the rod portion passes through the movable sleeve and the base portion abuts against the movable sleeve.

[0016] The high-stability telephoto lens of this invention includes two support units, and the second base has two slots corresponding to the support units respectively. The slots are spaced apart on the left and right sides of the second lens in the left-right direction.

[0017] The high-stability telephoto lens of this utility model has a second base with a lower shell and a lens frame that can be flipped relative to the lower shell. The lower shell has the through groove and an internal space. The lens frame is used to install the second lens and can be accommodated in the internal space.

[0018] The high-stability telephoto lens of this utility model includes a support unit that further includes a base for mounting the support arm. The support arm has a lower joint connected to the base, an arm portion connected to the lower joint, and an upper joint connected to the arm portion and the lens mount unit.

[0019] Another objective of this invention is to provide a high-stability telescope.

[0020] The high-stability telephoto lens of this invention includes a support unit, a lens mount unit, and at least one support unit.

[0021] The support unit includes a support arm. The lens mount unit includes a first lens mount and a second lens mount rotatably connected to one side of the first lens mount and disposed on the support arm. The first lens mount has a first base and a first lens. The second lens mount has a second base and a second lens. The second base has a lower shell disposed on the support arm and a frame rotatably disposed between the lower shell and the first lens mount for mounting the second lens. The lower shell has at least one through-slot spaced from the second lens, the through-slot extending through the front and rear sides in a front-rear direction.

[0022] At least one support unit is disposed on the lens mount unit, and the at least one support unit includes a support rod, a bearing, and a movable sleeve. The support rod is movably inserted through the slot of the second lens mount and has a first end and a second end arranged oppositely. The first end is pivotally mounted on the lens frame. The bearing is disposed on the second end of the support rod. The movable sleeve allows the support rod to movably insert and is pivotally mounted on the slot of the second mount. When the first lens mount and the second lens mount are in the open state, the bearing moves with the second end of the support rod and inserts into and locks into the movable sleeve, thereby locking the movable sleeve, and the support rod is supported between the lower shell and the lens frame.

[0023] The beneficial effects of this utility model are as follows: through the cooperation of the support rod of the at least one support unit, the bearing seat and the movable sleeve, the bearing seat is inserted and locked into the movable sleeve along with the second end of the support rod, which can support the first lens or the second lens without shaking, so that the first lens base and the second lens base can be stably supported in the open state, thus achieving high stability.

[0038] See Figures 1 to 3 The first embodiment of this high-stability telephoto lens is suitable for use on a desktop (not shown) and magnifies the image of an object (not shown) using optical principles. The object may be, for example, but is not limited to, a mobile phone or a book. When facing this embodiment, the user can maintain an appropriate distance while viewing the object without excessive forward head tilting, thus protecting eyesight and preventing neck and shoulder pain.

[0039] The high-stability telephoto lens includes a support unit 1, a lens mount unit 2, a lifting and adjustment unit 3, and at least one support unit 400. In this embodiment, two support units 400 are used for illustration.

[0040] The support unit 1 includes a base 11 extending in a front-rear direction X, a support arm 12 extending obliquely in a vertical direction Z from the rear side of the base 11, and a reinforcing rod 13 fixed to the base 11 and connected to the support arm 12. In this embodiment, the base 11 and the support arm 12 are integrally formed plates. In this embodiment, "front" refers to the direction of the present invention closer to the user, and "rear" refers to the direction of the present invention away from the user.

[0041] The lens mount unit 2 is disposed on the support arm 12 and includes a first lens mount 21, a second lens mount 22 connected to one side of the first lens mount 21 and disposed at the top end of the support arm 12, and a pivot mechanism 23 extending in a left-right direction Y and pivotally disposed between the first lens mount 21 and the second lens mount 22. Through the pivot mechanism 23, the first lens mount 21 can be in an open state relative to the second lens mount 22 (see...). Figure 1 ) and a closed state (see Figure 9 The rotating mechanism 23 can be flipped between the two sides. For details of the structure of the rotating mechanism 23, please refer to the Taiwan Patent Publication No. M657250U previously filed by the applicant in this case, and will not be repeated here.

[0042] In some embodiments, the first mirror mount 21 does not flip, and the rotating shaft mechanism 23 is omitted from the mirror mount unit 2. The first mirror mount 21 and the second mirror mount 22 are fixedly held in the open state.

[0043] The first lens mount 21 has a first base 211 and a first lens 212 disposed on the first base 211. The first base 211 has two receiving slots 213 located on the left and right sides of the first lens 212. Due to the viewing angle, only one receiving slot 213 is visible in the attached figure. When the first lens mount 21 is in the open state relative to the second lens mount 22, the first lens 212 is positioned above the object and is used to magnify the contents of the object.

[0044] The second lens mount 22 is inclined downwards and backwards to the support arm 12. The second lens mount 22 has a second base 221 slidably mounted at the top of the support arm 12, a second lens 222 mounted on the second base 221, and a light source 223 mounted on the bottom side of the second base 221. The second base 221 has at least one slot 224 spaced apart from the second lens 222. In this embodiment, two slots 224 are used as an example, and the slots 224 are spaced apart on the left and right sides of the second lens 222 in the left-right direction Y.

[0045] When the first lens mount 21 is flipped to the open state relative to the second lens mount 22, the first lens mount 21 and the second lens mount 22 form an angle A. The first lens 212 magnifies the image of the object and reflects it to the second lens 222, allowing the user to see the magnified image of the object through the second lens 222. The light source 223 is used to provide the light source required for optical magnification.

[0046] See Figure 2 , Figure 4 and Figure 5 Each of the slots 224 extends through the front and rear sides along the front-rear direction X. Each slot 224 has an elongated opening 225 located on the front side and extending substantially along the vertical direction Z, and a rear opening 226 opposite to the elongated opening 225 in the front-rear direction X. The dimension of the elongated opening 225 in the horizontal direction Y is smaller than the dimension of the rear opening 226 in the horizontal direction Y.

[0047] See Figure 1 and Figure 3 The lifting adjustment unit 3 is used to adjust the height of the mirror base unit 2 in the vertical direction Z. The lifting adjustment unit 3 has a knob 31 that is rotatably inserted through the support arm 12 and positioned on the second seat 221. By loosening the knob 31, the mirror base unit 2 can be pulled up and down relative to the bracket unit 1, thereby adjusting the height of the mirror base unit 2. The detailed structure of the lifting adjustment unit 3 is prior art and has many variations. Since those skilled in the art can deduce the extended details based on the above description, they will not be elaborated further. However, in some embodiments, the lifting adjustment unit 3 can be omitted, allowing the mirror base unit 2 to remain at a fixed height.

[0048] See Figures 2 to 4 The support unit 400 is disposed in the mirror base unit 2 and corresponds to the through groove 224 and the receiving groove 213, respectively. The support unit 400 is used to stably support the first mirror base 21 in the open state. In some embodiments, the support unit 400 may be a single unit, provided that the supporting force of the support unit 400 is sufficient.

[0049] See Figures 3 to 5 Each of the support units 400 includes a support rod 4 that can be movably passed through a corresponding through slot 224, a bearing 5 mounted on the support rod 4, a nut 6 that can be rotatably mounted on the support rod 4 and adjacent to the bearing 5, and a movable sleeve 7 mounted on the second seat 221 and through which the support rod 4 passes.

[0050] The support rod 4 is an elongated round bar with a first end 41 and a second end 42 arranged opposite to each other. The first end 41 is pivotally mounted in one of the receiving grooves 213 of the first seat 211. The second end 42 is movably passed through one of the through grooves 224 of the second seat 221. The second end 42 has an external thread 421.

[0051] See Figures 5 to 8 The bearing seat 5 is rotatably screwed to the external thread portion 421 of the support rod 4, so rotating the bearing seat 5 allows it to move back and forth relative to the support rod 4. In this embodiment, the bearing seat 5 has a cylindrical seat portion 51 and a rod portion 52 with an outer diameter smaller than that of the seat portion 51 and extending outward from the seat portion 51. The rod portion 52 has a cylindrical connecting section 521 connecting to the seat portion 51, a circumferentially surrounding concave annular groove 522 connecting to the connecting section 521, and a tapered section 523 connecting to the concave annular groove 522. The tapered section 523 extends gradually from the concave annular groove 522 in a direction opposite to that of the seat portion 51. The bearing seat 5 also has a through hole 53 penetrating the seat portion 51 and the rod portion 52, at least a portion of which is rotatably screwed to the external thread portion 421 of the support rod 4. The nut 6 is fixed to the end of the external thread 421 of the support rod 4, which can prevent the bearing seat 5 from coming off the support rod 4 due to excessive rotation.

[0052] The movable sleeve 7 is pivotally mounted on one of the slots 224 of the second base 221 and is frictionally inserted through which the support rod 4 passes. In this embodiment, the movable sleeve 7 has a shaft 71, a movable sleeve 72, a washer 73, a pin 74, and an elastic element 75.

[0053] The shaft 71 is disposed in one of the slots 224 of the second seat 221 and extends along the left-right direction Y.

[0054] The movable sleeve 72 is pivotally mounted on the shaft 71 and can pivot back and forth within the through groove 224. The movable sleeve 72 also allows the support rod 4 and the bearing seat 5 to movably pass through it. The movable sleeve 72 has an abutment wall 721, a peripheral wall 722 surrounding the abutment wall 721 and extending toward the seat portion 51 of the bearing seat 5, a hanging portion 723 disposed on the peripheral wall 722 and through which the shaft 71 passes, and two protrusions 724 spaced apart on the outer surface of the peripheral wall 722. The abutment wall 721 and the peripheral wall 722 define a sleeve hole 720 for the support rod 4 and the bearing seat 5 to pass through. The sleeve hole 720 has an inclined hole 725 facing the seat portion 51 of the bearing 5. The inclined hole 725 matches the shape of the tapered section 523 of the bearing 5, thus serving as a guide to facilitate the bearing 5's insertion into the sleeve hole 720 of the movable sleeve 72. The peripheral wall 722 has a radial through hole 726 located between the protrusions 724 and extending vertically from the outer surface to the sleeve hole 720, and a positioning hole 727 spaced apart from the radial through hole 726. The outer dimensions of the abutment wall 721 are larger than the dimensions of the elongated opening 225 of the through groove 224; that is, the dimensions of the elongated opening 225 are smaller than the dimensions of the abutment wall 721. The hanging portion 723 has a hanging hole 728 for the shaft 71 to pass through.

[0055] The washer 73 abuts against the front side of the movable sleeve 72 and is frictionally inserted through which the support rod 4 moves. The washer 73 is located between the movable sleeve 72 and the second seat 221, and the size of the washer 73 is larger than the size of the elongated opening 225. The washer 73 increases the damping of the support rod 4 when it moves relative to the movable sleeve 7.

[0056] The pin 74 is movable along the left-right direction Y, passing through the radial through hole 726 of the movable sleeve 72, and is used to extend into the concave annular groove 522 of the bearing seat 5. The end of the pin 74 that extends into the concave annular groove 522 is hemispherical.

[0057] One end of the elastic element 75 is fixed to the positioning hole 727, and the other end abuts against the pin 74. The elastic element 75 constantly pushes the pin 74 to move towards the sleeve hole 720. In this embodiment, the elastic element 75 is a straight sheet, but in other variations, other types of elastic elements, such as torsion springs or spring clips, can also be used. The installation method and position can also be changed, as long as the pin 74 can be constantly pushed to move towards the sleeve hole 720.

[0058] See Figure 1 , Figure 3 , Figure 9 and Figure 10Each of the support units 400 can be in a support position relative to the second base 221 (e.g., Figure 3 ) and an unsupported location (such as Figure 10 It can move between ( ). The following describes one of the support units 400 in detail.

[0059] See Figure 1 and Figure 3 When the first lens mount 21 is opened relative to the second lens mount 22, the first lens mount 21 will drive the first end 41 of the support rod 4 to move upward, so that the first end 41 is away from the second lens mount 22 and higher than the second end 42. The second end 42 of the support rod 4 enters the through groove 224. The shaft seat 5 moves with the second end 42 of the support rod 4 and passes into the movable sleeve 72, so that the movable sleeve 7 is locked and cannot move. At this time, the support unit 400 reaches the support position. Since the support rod 4 is stably supported between the first lens mount 21 and the second lens mount 22, it can keep the first lens mount 21 and the second lens mount 22 in the open state and support the first lens 212 without shaking.

[0060] See Figure 9 and Figure 10 During the process of the first mirror mount 21 closing relative to the second mirror mount 22 to the closed state, the first mirror mount 21 will drive the first end 41 of the support rod 4 to move downward, so that the first end 41 is lower than the second end 42 and adjacent to the second mirror mount 22. The second end 42 of the support rod 4 will move backward and rise, and drive the movable sleeve 72 to pivot backward, so that the shaft seat 5 moves away from the through groove 224 and disengages from the movable sleeve 7. At this time, the support unit 400 reaches the unsupported position.

[0061] Next, refer to Figure 11 (1) to Figure 11 (3) The continuous movement of the support unit 400 from the unsupported position to the supported position is described in detail.

[0062] like Figure 11 As shown in (1), during the process of the support unit 400 moving from the unsupported position to the supported position, the second end 42 of the support rod 4 will drive the bearing seat 5 to gradually approach the movable sleeve 72.

[0063] like Figure 11(2) As shown, the bearing seat 5 then passes through the sleeve hole 720 of the movable sleeve 72, and the tapered section 523 of the bearing seat 5 contacts the pin 74 and pushes the pin 74 outward, so that the pin 74 moves away from the sleeve hole 720. Then, the pin 74 pushes the elastic member 75 and causes the elastic member 75 to undergo elastic deformation.

[0064] like Figure 11 As shown in (3), the bearing seat 5 continues to move until the concave annular groove 522 aligns with the pin 74, and the seat portion 51 abuts against the movable sleeve 72. The pin 74 is pushed inward by the elastic force of the elastic member 75 and extends into the concave annular groove 522 of the bearing seat 5. Thus, the pin 74 locks the bearing seat 5 so that it cannot move relative to the movable sleeve 72. At this time, the support unit 400 reaches the support position.

[0065] Conversely, to move the support unit 400 from the supported position to the unsupported position, it is according to... Figure 11 (3) Figure 11 (2) Figure 11 (1) In the order of moving the bearing seat 5 and the support rod 4 together to the rear side so that the pin 74 disengages from the bearing seat 5, the bearing seat 5 can disengage from the movable sleeve 7, so that the support unit 400 can move to the unsupported position.

[0066] Furthermore, since the bearing seat 5 is rotatably screwed to the external thread portion 421 of the support rod 4, the support unit 400 can steplessly fine-tune the angle A between the first mirror base 21 and the second mirror base 22 in the open state by simply rotating the bearing seat 5 when the support unit 400 is in the support position, so that the angle A can be increased or decreased.

[0067] See Figure 12 and Figure 13 The second embodiment of this utility model is similar to the first embodiment, except that:

[0068] The support arm 12 of the bracket unit 1 has a lower joint 121 connected to the base 11, a rod-shaped arm 122 connected to the lower joint 121, and an upper joint 123 connected to the arm 122 and the mirror mount unit 2. The lower joint 121 and the upper joint 123 can rotate and be positioned, thereby adjusting the front-to-back position and elevation angle of the mirror mount unit 2. Since the lower joint 121 and the upper joint 123 are existing pivot joints with various variations, those skilled in the art can deduce the expanded details based on the above description, and therefore will not be elaborated further. This second embodiment omits the lifting adjustment unit 3 described in the first embodiment and instead uses the rotation of the lower joint 121 and the upper joint 123 to finely adjust the height of the mirror mount unit 2.

[0069] The second base 221 has a lower shell 227 rotatably connected to the upper joint 123, and a lens frame 228 rotatably disposed on the pivot mechanism 23 and capable of being flipped open relative to the lower shell 227. The lower shell 227 has slots 224 formed on its left and right sides, and also defines an internal space 229 between the slots 224. The lens frame 228 is used to mount the second lens 222 and can be accommodated in the internal space 229; the angle of the second lens 222 can be adjusted by rotating the lens frame 228.

[0070] Each of the support units 400 has its first end 41 pivotally mounted on the mirror frame 228. The second end 42 of each support unit 400 extends rearward through its corresponding slot 224. The component relationships of each support unit 400 relative to the second base 221 in the supported and unsupported positions are the same as in the first embodiment and will not be repeated here. When the first mirror base 21 is in the open state relative to the second mirror base 22 (e.g., ... Figure 12 When the second lens 222 is in motion, each of the support units 400 can move to the support position and be supported between the lower shell 227 and the frame 228, thus supporting the second lens 222 without wobbling, and also having the effect of high stability.

[0071] When the first lens mount 21 is in the closed state relative to the second lens mount 22 (e.g.) Figure 13 When the first seat 211 and the lower shell 227 are combined to cover the frame 228, the second end 42 of each support unit 400 moves further back to the unsupported position.

[0072] In summary, the high-stability telephoto lens of this invention, through the cooperation of the support rod 4, the bearing 5, and the movable sleeve 7 in each support unit 400, allows the bearing 5 to be locked into the movable sleeve 7 as the second end 42 of the support rod 4 passes through it. When each support unit 400 moves to the support position, it can support the first lens 212 or the second lens 222 without wobbling, ensuring that the first lens mount 21 and the second lens mount 22 are stably supported in the open state, thus achieving high stability. Therefore, it effectively achieves the purpose of this invention.

[0073] The above description is merely an embodiment of this utility model and should not be construed as limiting the scope of this utility model. Any simple equivalent changes and modifications made in accordance with the claims and description of this utility model shall still fall within the scope of this utility model.

The support rod is movably inserted through a slot in the second lens mount and has a first end and a second end arranged oppositely. The first end is pivotally mounted on the first base body. The bearing is disposed on the second end of the support rod. The movable sleeve allows the support rod to movably insert and pivotally mount on a slot in the second base body. When the first lens mount and the second lens mount are in the open state, the bearing moves with the second end of the support rod and inserts into and locks into the movable sleeve, thereby locking the movable sleeve. The support rod is supported between the first lens mount and the second lens mount.

2. The high-stability telescope according to claim 1, characterized in that: The first lens mount can be flipped relative to the second lens mount to a closed state, and the at least one support unit can move relative to the second body between a supported position and an unsupported position. In the supported position, the at least one support unit supports the first lens mount and the second lens mount in the open state, and the first end of the support rod is higher than the second end and away from the second lens mount. In the unsupported position, the first lens mount is flipped relative to the second lens mount to the closed state, and the first end of the support rod is lower than the second end and adjacent to the second lens mount. The second end of the support rod drives the shaft seat away from the through slot and disengages from the movable sleeve.

3. The high-stability telescope according to claim 2, characterized in that: The movable sleeve has a shaft provided in the slot of the second seat and extending in the left-right direction, a movable sleeve that is pivotally mounted on the shaft and allows the support rod and the shaft seat to move through it, and a pin that moves through the movable sleeve in the left-right direction. When the at least one support unit is in the supported position, the pin locks the shaft seat so that it cannot move relative to the movable sleeve. When the at least one support unit is in the unsupported position, the pin disengages from the shaft seat.

4. The high-stability telescope according to claim 3, characterized in that: The movable sleeve has a sleeve hole for the support rod to pass through, and a radial through hole extending vertically from the outer surface to the sleeve hole. The pin is movably disposed in the radial through hole. The bearing has a circumferentially surrounding concave annular groove for the pin to extend into, and a tapered section connecting the concave annular groove. The movable sleeve also has an elastic element that constantly pushes the pin to move toward the sleeve hole. When the at least one support unit moves between the supported position and the unsupported position, the pin is pushed by the tapered section and moves away from the sleeve hole, thereby causing the elastic element to undergo elastic deformation.

5. The high-stability telescope according to claim 4, characterized in that: The movable sleeve also has an abutment wall, a peripheral wall surrounding the abutment wall, and a hanging part disposed on the peripheral wall for the shaft to pass through. The sleeve hole is defined by the abutment wall and the peripheral wall. The through groove of the second seat has a long opening on the front side and a rear opening opposite to the long opening in the front-rear direction. The size of the long opening is smaller than the size of the abutment wall.

6. The high-stability telescope according to claim 5, characterized in that: The movable sleeve of the at least one support unit also has a positioning hole formed on the peripheral wall and two protrusions spaced apart on the peripheral wall, the radial through hole being located between the protrusions, the elastic element being a spring sheet with one end fixed to the positioning hole and the other end abutting against the pin.

7. The high-stability telescope according to claim 3, characterized in that: The movable assembly also includes washers for the frictional movement of the support rod.

8. The high-stability telescope according to claim 1, characterized in that: The second end of the support rod has an external thread, and the bearing seat of the at least one support unit is rotatably screwed to the external thread of the support rod.

9. The high-stability telescope according to claim 1, characterized in that: The bearing has a seat portion and a rod portion that is smaller than the seat portion and extends outward from the seat portion. When the first mirror mount and the second mirror mount are supported in the open state, the rod portion passes through the movable sleeve, and the seat portion abuts against the movable sleeve.

10. The high-stability telescope according to claim 1, characterized in that: It includes two support units, and the second base has two through slots corresponding to the support units respectively, the through slots being spaced apart on the left and right sides of the second lens in the left-right direction.

11. The high-stability telescope according to claim 1, characterized in that: The second base has a lower shell and a lens frame that can be flipped relative to the lower shell. The lower shell has the through slot and an internal space. The lens frame is for mounting the second lens and can be accommodated in the internal space.

12. The high-stability telescope according to claim 1, characterized in that: The support unit further includes a base for mounting the support arm, the support arm having a lower joint connected to the base, an arm portion connected to the lower joint, and an upper joint connected to the arm portion and the mirror base unit.

13. A high-stability telephoto lens, characterized in that: Include: Support unit, including support arms; A lens mount unit includes a first lens mount and a second lens mount rotatably connected to one side of the first lens mount and disposed on a support arm. The first lens mount has a first base and a first lens, and the second lens mount has a second base and a second lens. The second base has a lower shell disposed on the support arm and a frame rotatably disposed between the lower shell and the first lens mount for mounting the second lens. The lower shell has at least one through-slot spaced from the second lens, the through-slot extending through the front and rear sides in a front-rear direction. At least one support unit is disposed in the lens mount unit. The at least one support unit includes a support rod, a bearing, and a movable sleeve. The support rod is movably inserted through the slot of the second lens mount and has a first end and a second end arranged oppositely. The first end is pivotally mounted on the lens frame. The bearing is disposed on the second end of the support rod. The movable sleeve allows the support rod to move through and is pivotally mounted on the slot of the second mount.
