[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] refer to Figure 1-5 A specific embodiment of this utility model provides a pressure ring disassembly and assembly device, comprising: Support rod 3, with a torque wrench 1 installed at the top of support rod 3; The top ends of the two sets of first connecting rods 5 are respectively slidably connected to the two sides of the support rod 3 in the radial direction, and the bottom ends of the two sets of first connecting rods 5 are inserted into the edge of the pressure ring 17. Clamping arms: Two sets of clamping arms are symmetrically connected to both sides of the support rod 3 and are manually clamped to both sides of the lens barrel 8.

[0019] When fixing optical lenses, clamping rings are often used to ensure their firmness. When installing clamping rings on optical lenses, tweezers and other general clamping ring tightening wrenches are mainly used. The disadvantage is that the use of these methods mainly depends on the operator's strength and feel, which requires a high level of experience. For novices, the tools are easy to slip, causing scratches on the lens surface. In addition, the tightening force cannot be quantified during operation, and the assembly efficiency cannot be improved. In this application, by manually sliding the two sets of first connecting rods 5, the bottom of the first connecting rod 5 is inserted into the edge of the pressure ring 17. The main function of the clamping arm is to manually clamp the first connecting rod 5 and the pressure ring 17 on both sides of the lens barrel 8 after they are installed in place, thereby ensuring that the support rod 3 does not shift during operation, firmly grips the lens barrel 8, and that the two sets of first connecting rods 5 are stably inserted into the pressure ring 17, achieving an auxiliary positioning and protection effect. This stabilizes operation, reduces operational difficulty, and avoids scratching the optical lens. The torque wrench 1 is mainly used to rotate the support rod 3, thereby loosening or tightening the pressure ring 17 through the two sets of first connecting rods 5. During tightening, it ensures the tightening torque of the pressure ring 17. Overall, this application can effectively avoid scratching the optical lens due to misoperation, reduce operational difficulty, and accurately control the tightening torque.

[0020] Further optimization of the scheme also includes slide rod 4, double-acting screw 6 and rotating shaft 20. Two sets of slide rods 4 are symmetrically and vertically fixedly connected to both sides of the support rod 3. The first connecting rod 5 is sleeved on the slide rod 4. The double-acting screw 6 is rotatably connected to the bottom end of the support rod 3 and is set perpendicular to the support rod 3. The two sets of first connecting rods 5 are threaded on both ends of the double-acting screw 6. The rotating shaft 20 is coaxially set inside the support rod 3 and is rotatably connected to the support rod 3. The bottom end of the rotating shaft 20 is connected to the double-acting screw 6 through a gear set.

[0021] refer to Figure 1-3 The main function of the slide bar 4 is to provide a sliding track for the first connecting rod 5 and limit the movement trajectory of the first connecting rod 5. The rotating shaft 20 and the double-acting screw 6 are driven by a gear set. The double-acting screw 6 is driven to rotate by manually rotating the rotating shaft 20, which in turn drives the two sets of first connecting rods 5 to move closer or further away from each other along the slide bar 4. The distance between the two sets of first connecting rods 5 is adjusted according to the size of the pressure ring 17.

[0022] Further optimization of the design also includes an operating hole 18. The top of the support rod 3 has an operating hole 18, through which the screwdriver is adapted to the top of the rotating shaft 20.

[0023] refer to Figure 3 The main function of the operating hole 18 is to provide operating space for the screwdriver, so that the rotating shaft 20 can be rotated by manually operating the screwdriver; the top of the rotating shaft 20 is provided with a cross groove, so that either a flathead screwdriver or a Phillips screwdriver can be used.

[0024] The scheme is further optimized. The gear set includes a first bevel gear 21 and a second bevel gear 22. The first bevel gear 21 and the second bevel gear 22 are respectively located in the support rod 3. The first bevel gear 21 is coaxially fixedly connected to the bottom end of the rotating shaft 20. The second bevel gear 22 is coaxially fixed on the double-acting lead screw 6 and meshes with the first bevel gear 21.

[0025] refer to Figure 3 By manually rotating the shaft 20, power is transmitted to the bidirectional lead screw 6 through the first bevel gear 21 and the second bevel gear 22 in sequence, thereby driving the two sets of first connecting rods 5 to move closer or further apart along the slide rod 4.

[0026] The design is further optimized so that the clamping arm includes a sliding sleeve 9 and a second connecting rod 11. The sliding sleeve 9 is axially sleeved on the support rod 3. The top ends of the two sets of second connecting rods 11 are symmetrically rotated and connected to both sides of the sliding sleeve 9. The bottom ends of the two sets of second connecting rods 11 are manually clamped to both sides of the lens barrel 8.

[0027] refer to Figure 2-3 When the bottom ends of the two sets of second connecting rods 11 are manually clamped on both sides of the lens barrel 8, the sliding sleeve 9 and the support rod 3 maintain a sliding connection. At the same time, the clamping distance of the second connecting rod 11 is adapted to different sizes of lens barrel 8. Specifically, during the process of loosening the pressure ring 17, the pressure ring 17 will move axially, which will push the first connecting rod 5 and the support rod 3 to move axially relative to the sliding sleeve 9. The sliding relationship between the sliding sleeve 9 and the support rod 3 is conducive to the smooth operation process.

[0028] In a further optimized design, the clamping arm also includes a thrust bearing 13, a fixing plate 15, and a spring 14. The thrust bearing 13 is sleeved on the support rod 3 and fixedly connected to the bottom of the sliding sleeve 9. The fixing plate 15 is fixedly sleeved on the support rod 3 and located below the thrust bearing 13. The spring 14 is sleeved on the support rod 3 and fixedly connected between the bottom of the thrust bearing 13 and the fixing plate 15.

[0029] refer to Figure 3During the process of rotating the support rod 3 by the torque wrench 1, the fixed plate 15 and the sliding sleeve 9 will rotate relative to each other. In order to ensure the stability of the spring 14, a thrust bearing 13 (such as a thrust tapered roller bearing) is installed between the bottom of the sliding sleeve 9 and the top of the spring 14, so that the spring 14 and the fixed plate 15 can rotate synchronously. In its initial state, spring 14 primarily bears the weight of the sliding sleeve 9, thrust bearing 13, and second connecting rod 11. When the two sets of first connecting rods 5 are inserted into the pressure ring 17, manually operating the two sets of clamping second connecting rods 11 and the lens barrel 8 further compresses spring 14. Whether tightening or loosening the pressure ring 17, the pressure ring 17 always bears the spring force of spring 14 through the first connecting rod 5, support rod 3, and fixing plate 15, ensuring stable contact between the pressure ring 17 and the lens barrel 8. This prevents the pressure ring 17 from moving arbitrarily during rotation. Even when the torque wrench 1 is removed, it prevents the torque wrench 1 from moving the pressure ring 17 axially by driving the support rod 3 and first connecting rod 5, thus preventing the first connecting rod 5 or the pressure ring 17 from contacting the surface of the optical lens. After the second connecting rod 11 is completely released, spring 14 partially rebounds (returning to its initial state), allowing axial separation of the first connecting rod 5 and the pressure ring 17.

[0030] In a further optimized design, the clamping arm also includes a clamping plate 12 and a rubber block 16. The clamping plate 12 is rotatably connected to the bottom end of the second connecting rod 11, and the rubber block 16 is fixedly connected to the side of the clamping plate 12 near the lens barrel 8.

[0031] refer to Figure 3-5 After the two sets of first connecting rods 5 are inserted into the pressure ring 17 and installed in place, the two sets of clamping plates 12 are operated with one hand (by squeezing radially towards the lens barrel 8) to make the two sets of rubber blocks 16 fit tightly against the outer wall of the lens barrel 8. This arrangement prevents relative sliding between the lens barrel 8 and the hand while the other hand rotates the pressure ring 17. When the clamping plates 12 and rubber blocks 16 are completely released, the first connecting rods 5 and the pressure ring 17 can be axially separated.

[0032] In a further optimized design, the clamping arm also includes an extension rod 10. The first ends of the two sets of extension rods 10 are symmetrically fixedly connected to both sides of the sliding sleeve 9, and the second ends of the extension rods 10 are hinged to the top end of the second connecting rod 11.

[0033] refer to Figure 2-3 The main function of the extension rod 10 is to control the distance between the second connecting rod 11 and the slide rod 4 and the double-acting lead screw 6, so as to avoid interference between the second connecting rod 11 and the slide rod 4 and the double-acting lead screw 6 during the rotation of the support rod 3; wherein, the second connecting rod 11 can also be set to a bent state (e.g. Figure 2-3 This ensures that the operation of the pressure ring 17 is smooth.

[0034] Further optimization of the scheme also includes a square end 19, the top of the support rod 3 is set as a square end 19, and the torque wrench 1 is sleeved on the square end 19 through the sleeve 2.

[0035] The square end 19 has a rectangular cross-section (not shown in the figure) and mates with the sleeve 2 to facilitate the torque wrench 1 in rotating the support rod 3.

[0036] Further optimization of the design also includes a locking head 7, with the bottom end of the first connecting rod 5 detachably connected to the locking head 7, and the locking head 7 having a groove 23 on the edge of the pressure ring 17 (such as...). Figure 4 It is compatible with the target audience.

[0037] The chuck 7 can be magnetically or threadedly connected to the bottom end of the first connecting rod 5, making it easy to disassemble and replace. The shape of the chuck 7 can be set to cylindrical or straight, which can be adapted to the groove 23 on the edge of the pressure ring 17.
