The output end of the motor 12 is drivingly connected to a transmission rod 13. The transmission rod 13 is connected to the activity slot 11 by a bearing and a driving gear 14 is arranged on the outer side. A transmission gear 15 is meshingly connected to the outer side of the driving gear 14. The transmission gear 15 is meshingly connected to the driven gear 16;

[0022] A fiber optic connector is a device for detachably and movably connecting between optical fibers. It precisely docks the two end faces of the optical fibers so that the optical energy output by the transmitting optical fiber can be maximally coupled into the receiving optical fiber, and the influence on the system caused by its insertion into the optical link is minimized. This is the basic requirement of the fiber optic connector. When producing fiber optic connectors, a crimping device is needed to connect the ferrule to it, and then the fiber optic connector can truly play its role;

[0023] When crimping the ferrule of the optical fiber connector, usually no additional auxiliary fixing operation is performed on the optical fiber connector body. During the crimping operation, it is easy to be skewed, which is not conducive to improving the production qualification rate of the optical fiber connector.

[0024] Place the optical fiber connector on the device base 1, then turn on the motor 12, the motor 12 drives the transmission rod 13 to rotate the driving gear 14, and the driving gear 14 drives the driven gear 16 to rotate through the transmission gear 15, so as to achieve the purpose of rotating the main rotating rod 21. When the main rotating rod 21 rotates, the cam 2 is attached to the side movable plate 3 and switches from the short head to the long head, so that the side movable plate 3 moves toward the middle direction until the side movable plate 3 fixes the optical fiber connector, and the crimping assembly 10 can be used to crimp the ferrule;

[0025] When the optical fiber connector is crimped, it can be firmly fixed on the device base 1, so that it will not be skewed during the crimping process, effectively improving the production efficiency of the optical fiber connector. At the same time, the structure of the mechanism is simple and does not require manual assistance, which can free up manpower.

[0026] In other embodiments, the present embodiment discloses, please Figures 1 - 2 As shown, two L-shaped cover plates 22 are symmetrically provided on the top of the device base 1, the cam 2 is located on the inner side of the L-shaped cover plate 22, and the main rotating rod 21 and the L-shaped cover plate 22 are rotatably connected; through this design, the cam 2 can be hidden and protected to prevent dust and the like from falling from directly above, and the rotation stability of the main rotating rod 21 can also be improved.

[0027] In other embodiments, the present embodiment discloses, please Figure 1 As shown, the four corners of the bottom of the device base 1 are provided with heightened support columns 18, and the bottom surface of the device base 1 is provided with heat dissipation holes 17 which are connected with the movable groove 11, and the heat dissipation holes 17 correspond to the positions of the motor 12. Through this design, the height of the device base 1 can be increased, leaving a gap at the bottom of the device base 1, so that the heat of the motor 12 during braking can be dissipated, thereby avoiding damage due to heat accumulation.

[0028] In other embodiments, the present embodiment discloses, please Figure 3 As shown, a non-slip pad 31 is provided on the side surface of the side movable plate 3 away from the cam 2, and a rubber ring is provided on the outer side of the cam 2. Through this design, the side movable plate 3 will not damage the connector surface due to friction when fixing the optical fiber connector, effectively protecting both.

[0029] Embodiment 2:

[0030] In other embodiments, the present embodiment discloses, please Figures 1 - 4As shown, it further includes a sliding component. The sliding component includes a positioning slider 32, which is arranged on the bottom end face of the side movable plate 3. A positioning chute 35 is formed on the top end face of the device base 1. The positioning slider 32 is slidably connected to the inner side of the positioning chute 35. A limiting slide bar 33 is arranged on the outer side of the positioning slider 32. A limiting chute 36 is formed on the inner side of the positioning chute 35. The limiting slide bar 33 is slidably connected to the inner side of the limiting chute 36. A spring 34 is arranged between the positioning slider 32 and the positioning chute 35;

[0031] When the side movable plate 3 is pushed by the cam 2 to move, the positioning slider 32 and the limiting slide bar 33 slide respectively on the inner sides of the positioning chute 35 and the limiting chute 36, so that the side movable plate 3 always translates in a straight line, and at the same time maintains connectivity with the device base 1. Meanwhile, the spring 34 is compressed, causing the spring 34 to contract. As a result, when there is no push from the cam 2, the side movable plate 3 will be pushed by the spring 34 to move away from the center point of the device base 1, facilitating the placement of the optical fiber processor; improving the connection tightness between the side movable plate 3 and the device base 1, preventing the side movable plate 3 from skewing during the sliding process, and enabling better matching with the fixing mechanism for use.
