[0002] Glasses are a combination of lenses and frames that are worn in front of the eyes to improve vision, protect the eyes or for decorative purposes. Glasses can correct a variety of vision problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia, etc. Glasses are composed of lenses and frames.

[0003] Traditional clamps for cutting glasses temples generally clamp the glasses temples by adjusting threaded rods. This method is still not fast and convenient enough. When the cutting workload is large, workers need to repeatedly turn the threaded rods to adjust and clamp the glasses temples, which not only wastes time but also makes workers easily fatigued. Utility Model Content

[0004] The utility model discloses a universal clamp for cutting the temples of glasses, which aims to solve the technical problem that the clamps for cutting the temples of glasses generally clamp the temples of glasses by adjusting threaded rods, but this method is still not fast and convenient enough.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0025] The utility model discloses a universal clamp for cutting the temples of glasses, which is mainly used in traditional clamps for cutting the temples of glasses. Generally, the temples of glasses are clamped by adjusting the threaded rods. This method is still not fast and convenient enough. When the cutting workload is large, workers need to repeatedly turn the threaded rods to adjust and clamp the temples of glasses, which not only wastes time but also makes workers easily tired.

[0026] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 A universal fixture for cutting glasses temples, comprising a mounting frame 1 and a crank 5, and further comprising:

[0027] A limiting mechanism, used to limit the crank 5;

[0028] Universal mechanism, used to adjust the angle of the fixture;

[0029] The inner walls on both sides of the mounting frame 1 are movably connected to the rotating rod 2 through bearings, and the outer wall of the rotating rod 2 is sleeved with a rotating block 3. The outer walls of both sides of the mounting frame 1 are provided with a fixed frame 16, and the inner wall of the fixed frame 16 is movably connected to the movable clamp 4 through a rotating shaft. The opposite end of the movable clamp 4 is fixedly connected to a clamping block 14. The end of the rotating rod 2 away from the clamping block 14 is connected to one end of the crank 5. The outer walls on the opposite side of the two clamping blocks 14 are each provided with an opening 15. The outer walls on both sides of the mounting frame 1 are each provided with a hole, and a sliding rod 17 is inserted into the inside of the hole. The sliding rod 17 corresponds to the position of the rotating block 3, and the two ends of the sliding rod 17 are respectively in contact with the rotating block 3 and the movable clamp 4;

[0030] The universal mechanism includes a top seat 8 installed on the bottom outer wall of the mounting frame 1, a middle seat 7 is installed on the bottom outer wall of the top seat 8, a base 6 is installed on the bottom of the middle seat 7, one side outer wall of the top seat 8 and the middle seat 7 is provided with the same second support plate 10, one side outer wall of the base 6 and the middle seat 7 is provided with the same first support plate 9, one side outer wall of the first support plate 9 and the second support plate 10 are symmetrically opened with two slide grooves 11, and nuts are inserted into the inside of the slide grooves 11.

[0031] Among them, the outer walls on both sides of the rotating block 3 are set to cross-symmetrical arc-shaped protrusion structures. The clamping and release of the movable clamp 4 is achieved by changing the distance from the center of the rotating block 3 to the sliding rod 17. The opening 15 is set to an arc-shaped structure. At the same time, the outer wall on the opposite side of the clamping block 14 is made of rubber material, which can better clamp the temples of the glasses.

[0032] Furthermore, a tension spring structure is provided at the fixing frame 16 and the movable clamp 4, so that the movable clamp 4 automatically returns to the position before clamping when the temple of the glasses is released.

[0033] When the eyeglasses are in use, the temples are aligned with the openings 15 on the clamping block 14 and the crank 5 is turned. The crank 5 drives the rotating rod 2 to rotate, and then drives the rotating block 3 to rotate. The sliding rod 17 slides along the outer wall of the rotating block 3, and the position of the movable clamp 4 close to the sliding rod 17 is pushed out and extended outward under the action of the cross-symmetrical arc-shaped protrusion structure of the rotating block 3, thereby causing the movable clamp 4 to rotate, and finally the clamping block 14 clamps the temples of the eyeglasses. After the cutting is completed, the crank 5 is turned in the opposite direction, and the rotating block 3 rotates back. Under the action of the tension spring, the movable clamp 4 and the sliding rod 17 are restored to their original positions, and the temples of the eyeglasses can be loosened. When cutting at other angles is required, the cutting angle can be adjusted by adjusting the position of the nuts on the first support plate 9 and the second support plate 10 on the slide groove 11.

[0034] Reference Figure 1 and Figure 4 In a preferred embodiment, the limiting mechanism includes a stopper 13 fixedly mounted on the outer wall of one side of the mounting frame 1 , and the stopper 13 is located on the positive side of the rotating rod 2 close to the second support plate 10 .

[0035] Specifically, when the crank 5 is rotated to clamp the temples of the glasses, the crank 5 is blocked by the block 13 and its rotation position is limited, thereby preventing the crank 5 from rotating excessively.

[0036] Working principle: when in use, align the temple of the glasses with the opening 15 on the clamping block 14, turn the crank 5, and stop when the crank 5 hits the stopper 13. During the rotation, the crank 5 drives the rotating rod 2 to rotate, and then drives the rotating block 3 to rotate, and the slide bar 17 slides along the outer wall of the rotating block 3. The position of the movable clamp 4 close to the slide bar 17 is pushed out and extended outward under the action of the cross-symmetrical arc-shaped protrusion structure of the rotating block 3, so that the movable clamp 4 rotates, and finally the clamping block 14 clamps the temple of the glasses. After cutting is completed, turn the crank 5 in the opposite direction, and the rotating block 3 rotates back. Under the action of the tension spring, the movable clamp 4 and the slide bar 17 return to their original position, and the temple of the glasses can be loosened. When cutting at other angles is required, the cutting angle can be adjusted by adjusting the position of the nuts on the first support plate 9 and the second support plate 10 on the slide groove 11.

[0037] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
