[0026] The fixing plate 100 is irregular in shape. The fixing plate 100 is divided into a fixing portion 110 and an assembly portion 120. The fixing portion 110 and the assembly portion 120 are integrally formed. A plurality of threaded holes are provided on the fixing portion 110. In the actual production process, screws are used to fix the fixing plate 100 on the placement surface through the threaded holes.

[0027] The assembly portion 120 is in the shape of a rectangular parallelepiped, and a recessed storage groove 121 is provided on the side of the assembly portion 120. The storage groove 121 is roughly rectangular. In another specific embodiment, the shape of the storage groove 121 is not limited. A first notch and a second notch are provided on the side wall of the storage groove 121. A first stopper 130 is provided in the first notch. The first stopper 130 is a trapezoidal block. The upper surface of the first stopper 130 forms an angle of 0 degrees with the horizontal plane, and the lower surface of the first stopper 130 forms an angle of 8 degrees with the horizontal plane. A first limiting groove 122 is formed between the upper surface of the first stopper 130 and the side wall of the storage groove 121, and a third limiting groove 124 is formed between the lower surface of the first stopper 130 and the side wall of the storage groove 121.

[0028] A second stopper 140 is provided in the second notch. The second stopper 140 is a trapezoidal block. The shape of the second stopper 140 is the same as that of the first stopper 130. The upper surface of the second stopper 140 forms an angle of 8 degrees with the horizontal plane, and the lower surface of the second stopper 140 forms an angle of 0 degrees with the horizontal plane. A fourth limiting groove 125 is formed between the upper surface of the second stopper 140 and the side wall of the storage groove 121, and a second limiting groove 123 is formed between the lower surface of the second stopper 140 and the side wall of the storage groove 121.

[0029] The upper surface of the first stopper 130 and the lower surface of the second stopper 140 are located on the same horizontal plane, and the lower surface of the first stopper 130 and the upper surface of the second stopper 140 are located on the same inclined plane.

[0030] A through hole 126 is also provided in the assembly portion 120. The through hole 126 is cylindrical and passes through the assembly portion 120. The through hole 126 is connected to the center of the storage slot 121. The connecting rod 200 is roughly cylindrical and passes through the through hole 126. The inner diameter of the through hole 126 is larger than the outer diameter of the connecting rod 200, so that the connecting rod 200 can slide in the through hole 126.

[0031] Two positioning grooves 210 are provided at one end of the connecting rod 200 close to the storage groove 121, and the limit block 300 includes a mounting portion 310 and a limit portion 320. The mounting portion 310 is cylindrical, and two limit portions 320 are provided on both sides of the mounting portion 310. The limit portions 320 are in the shape of a rectangular parallelepiped. The two limit portions 320 are symmetrical about the mounting portion 310, and the mounting portion 310 and the limit portions 320 are integrally formed. The limit portion 320 is provided in the positioning groove 210 of the connecting rod 200 to facilitate fixing the limit block 300 to the end of the connecting rod 200.

[0032] The shape of the limiting portion 320 matches the shapes of the first limiting groove 122 , the second limiting groove 123 , the third limiting groove 124 and the fourth limiting groove 125 , so that the limiting portion 320 cannot shake in the above-mentioned limiting grooves to ensure the stability of fixing and clamping the optical fiber ferrule.

[0033] The optical fiber ferrule fixing fixture with switchable angles also includes a sleeve 220, which is cylindrical in shape. The sleeve 220 is sleeved on the connecting rod 200, and the sleeve 220 is located in the through hole 126. The sleeve 220 is fixedly assembled with the connecting rod 200. The optical fiber ferrule fixing fixture with switchable angles also includes an assembly plate 400, which is arranged on the side of the sleeve 220 away from the limit block 300. The assembly plate 400 is sleeved on the connecting rod 200. The assembly plate 400 is rectangular in shape. The assembly plate 400 is vertically arranged, and an assembly hole is respectively provided at the four corners of the assembly plate 400. The screws fix the assembly plate 400 and the assembly portion 120 of the fixing plate 100 through the assembly holes to fix the position of the connecting rod 200.

[0034] The angle-switchable optical fiber ferrule fixing fixture also includes a spring 500, which is sleeved on the connecting rod 200 and located between the limit block 300 and the sleeve 220. A resistance portion 127 is also provided on the side of the through hole 126 close to the storage groove 121. The resistance portion 127 is annular and is integrally formed with the fixing plate 100. One end of the spring 500 close to the storage groove 121 is in resistance to the resistance portion 127, while the other end is in resistance to the sleeve 220.

[0035] To summarize, the connecting rod 200 is manually pressed so that the sleeve 220 compresses the spring 500, thereby causing the limit block 300 to move away from the storage slot 121. The connecting rod 200 is then manually rotated according to the type of optical fiber ferrule to adjust the angle of the limit block 300. After the connecting rod 200 is released, the connecting rod 200 drives the limit block 300 to move toward the storage slot 121 under the action of the spring 500. When the limit block 300 falls into the first limit slot 122 and the second limit slot 123, the optical fiber ferrule fixing fixture with switchable angles can clamp the optical fiber ferrule at 0 degrees. When the limit block 300 falls into the third limit slot 124 and the fourth limit slot 125, the optical fiber ferrule fixing fixture with switchable angles clamps the optical fiber ferrule at 8 degrees.

[0036] A cutting plane 230 is also provided at one end of the connecting rod 200 away from the stop block 300. The cutting plane 230 is rectangular. The optical fiber ferrule fixing fixture with switchable angles also includes a clamping assembly 600. The clamping assembly 600 includes a fixing seat 610 and a rotating arm 620. The fixing seat 610 is fixedly assembled on the cutting plane 230. The design of the cutting plane 230 can make the fixing seat 610 more stably fixed on the connecting rod 200. A groove 611 is also provided in the middle of the side of the fixing seat 610 away from the connecting rod 200. The shape of the groove 611 matches the shape of the end of the optical fiber ferrule. The rotating arm 620 is rotatably assembled with the fixing seat 610. A pressing block 621 is provided at the position of the rotating arm 620 corresponding to the groove 611. The pressing block 621 is fixedly assembled with the rotating arm 620.

[0037] In summary, in actual production, when the optical fiber ferrule needs to be fixed, the end of the optical fiber ferrule is manually placed in the groove 611 of the fixing seat 610, and the rotating arm 620 is rotated to fix the optical fiber ferrule in the groove 611 through the pressing block 621.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. For those skilled in the art, various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application.
