[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 4As shown, an angle-adjustable fiber optic polarizer includes a worktable 1. A support leg 2 is fixedly connected to the bottom of the worktable 1. A first groove 3 is formed at the bottom of the worktable 1. A first motor 4 is fixedly connected inside the first groove 3. A connecting rod 5 is fixedly connected to the output end of the first motor 4. A support frame 6 is fixedly connected to the top of the connecting rod 5. A second groove 7 is formed inside the support frame 6. A second motor 8 is fixedly connected inside the second groove 7. A first screw 9 is fixedly connected to the output end of the second motor 8. A first moving block 10 is threadedly connected to the outer side of the first screw 9. A connecting plate 11 is rotatably connected to the outer side of the first moving block 10 through a bearing. A first connecting block 12 is fixedly connected to the top of the support frame 6. A polarizer body 13 is rotatably connected to the inner side of the first connecting block 12 through a bearing. A second connecting block 14 is fixedly connected to the bottom of the polarizer body 13. The top of the connecting plate 11 is rotatably connected to the second connecting block 14 through a bearing.

[0021] refer to Figures 1 to 4 A first bevel gear 15 is fixedly connected to the outer side of the connecting rod 5. A first rotating rod 16 is movably connected to the inside of the worktable 1. A second bevel gear 17 located in the first groove 3 is fixedly connected to the outer side of the first rotating rod 16. The second bevel gear 17 meshes with the first bevel gear 15. A third bevel gear 18 is fixedly connected to the outer side of the first screw 9. A second rotating rod 19 is movably connected to the inside of the support frame 6. A fourth bevel gear 20 located in the second groove 7 is fixedly connected to the outer side of the second rotating rod 19. The fourth bevel gear 20 meshes with the third bevel gear 18.

[0022] As a technical optimization of this utility model, by setting a first bevel gear 15, a second bevel gear 17 and a first rotating rod 16, when the first motor 4 does not rotate, the first bevel gear 15 can be driven to rotate by the first rotating rod 16, which in turn drives the connecting rod 5 to continue rotating. By setting a third bevel gear 18, a fourth bevel gear 20 and a second rotating rod 19, the first screw 9 can still be driven to rotate by the second rotating rod 19. In case the first motor 4 and the second motor 8 are out of power and cannot rotate, the first rotating rod 16 and the second rotating rod 19 can be manually rotated to adjust the angle of the deflector body 13.

[0023] refer to Figures 1 to 4 The top of the workbench 1 is fixedly connected to a first fixing block 21, and the outside of the support frame 6 is fixedly connected to a second fixing block 22. The first fixing block 21 and the second fixing block 22 are both provided with moving grooves 23. The inside of the first fixing block 21 and the second fixing block 22 are both movably connected to a second screw 24. The outside of the second screw 24 is threadedly connected to a second moving block 25. The bottom of the second moving block 25 is fixedly connected to a limit ring 26. The limit ring 26 is used in conjunction with the first rotating rod 16 and the second rotating rod 19.

[0024] As a technical optimization of this utility model, by setting a second screw 24 and a second moving block 25, the limiting ring 26 can be driven to move up and down. When the first rotating rod 16 and the second rotating rod 19 have finished rotating, the height of the limiting ring 26 can be adjusted so that it fits against the surface of the first rotating rod 16 and the second rotating rod 19, increasing the resistance when the first rotating rod 16 and the second rotating rod 19 rotate, limiting the first rotating rod 16 and the second rotating rod 19, and preventing the first rotating rod 16 and the second rotating rod 19 from rotating on their own.

[0025] refer to Figures 1 to 4 A cylinder 27 is fixedly connected to the top of the workbench 1. A base plate 28 is fixedly connected to the output end of the cylinder 27. A limit groove 29 is opened on the inner side of the support leg 2. The base plate 28 is movably connected to the limit groove 29.

[0026] As a technical optimization of this utility model, by setting up a cylinder 27, a base plate 28 and a limiting groove 29, the cylinder 27 can push the base plate 28 to move up and down, adjust the height of the worktable 1, and then adjust the angle of the deflector body 13.

[0027] refer to Figures 1 to 4 The first rotating rod 16, the second rotating rod 19 and the second screw 24 are all fixedly connected to handles 30, and the outer side of the handles 30 is provided with anti-slip texture 31.

[0028] As a technical optimization of this utility model, by setting a handle 30 and anti-slip texture 31, it is convenient to manually rotate the first rotating rod 16, the second rotating rod 19 and the second screw 24, and prevents the hand from slipping during rotation.

[0029] refer to Figures 1 to 4 The inner side of the second groove 7 is provided with a first sliding groove 32, and the outer side of the first moving block 10 is fixedly connected with a first slider 33. The first sliding groove 32 and the first slider 33 are movably connected.

[0030] As a technical optimization of this utility model, by setting the first sliding groove 32 and the first sliding block 33, the stability of the first moving block 10 when moving up and down is increased, and the first moving block 10 is prevented from rotating.

[0031] The working principle and usage process of this utility model are as follows: The first motor 4 drives the connecting rod 5 to rotate, which in turn drives the support frame 6 and the first bevel gear 15 to rotate. The support frame 6 drives the second motor 8 and the first connecting block 12 to rotate, which in turn drives the deflector body 13 to rotate laterally. The first bevel gear 15 simultaneously drives the second bevel gear 17 to rotate, causing the first rotating rod 16 to rotate. The second motor 8 drives the first screw 9 to rotate, which in turn drives the first moving block 10 to move up and down. The first moving block 10 drives the second connecting block 14 to rotate via the connecting plate 11, which in turn drives the left side of the deflector body 13 to rotate longitudinally, adjusting the angle of the deflector body 13. When the first motor 4 and the first connecting rod 5 rotate, the deflector body 13 rotates horizontally. When the second motor 8 is out of power, the first rotating rod 16 is rotated by the handle 30, which drives the second bevel gear 17 to rotate. The second bevel gear 17 drives the connecting rod 5 to rotate through the first bevel gear 15. The second rotating rod 19 is rotated by the handle 30, which drives the fourth bevel gear 20 to rotate, which drives the third bevel gear 18 to rotate. The third bevel gear 18 drives the first screw 9 to rotate, allowing the angle of the deflector body 13 to be adjusted. The second screw 24 is rotated by the handle 30, which drives the second moving block 25 to move down. The second moving block 25 drives the limiting ring 26 to move down, so that it is in contact with the surfaces of the first rotating rod 16 and the second rotating rod 19, thus positioning the first rotating rod 16 and the second rotating rod 19.
