A transmission unit is provided between the clamping unit 31 and the clamping unit 31 thereon. When the two joysticks 11 undertake external operations to drive the two supporting units 21 to approach, the two clamping units 31 can follow the supporting unit 21 to form a pair of optical fibers. During the clamping of the pigtail 5, when the two supporting units 21 continue to approach, the two clamping units 31 can slide relative to the supporting unit 21 due to the transmission of the transmission unit, thereby driving the optical fiber pigtail 5 away from the device 4.

In this embodiment, referring to FIG. 1 , the specific articulation mode of the two joysticks 11 may refer to the articulation mode of the existing tool pliers, which will not be repeated here. Wherein, each joystick 11 is divided into two sections along its length direction by its hinged connection with another joystick 11. For convenience of description, the longer section is called the control section 111, and the other section is called the control section 111. In the installation section 112, the above-mentioned support unit 21 is specifically fixed on the installation section 112. In order to facilitate the operation of the operation section 111 and make the operation more secure, in this embodiment, the two operation sections 111 are covered with insulating materials. layer, and the insulating material layer is preferably made of an elastic material, such as a silicone spacer.

Referring to FIGS. 1 and 3 , the above-mentioned support unit 21 is specifically a support block fixed on the installation section 112 , and the two support blocks are arranged opposite to each other, and the above-mentioned two clamping units 31 are respectively arranged on the two support blocks. A clamping unit 31 is slidably provided on the opposite surface 211 , that is, the opposite surfaces 211 of the two support blocks, wherein the opposite surface 211 of the support block refers to the surface of the support block facing the other support block. In this embodiment, the opposite surfaces 211 of the two support blocks are arranged at an included angle, specifically in an "eight" shape, and along the pulling out direction of the fiber pigtail 5, the distance between the opposite surfaces 211 of the two support blocks gradually increases. Great set.

The interfaces of the existing equipment 4 are usually concentrated together, that is, the optical fiber pigtail 5 may be arranged in parallel with the interfaces connected to other lines. In order to facilitate the clamping of the optical fiber pigtail 5, in this embodiment, referring to FIG. 4, the above The support block is specifically fixed on the radial side wall of the installation section 112 , and the support block is at least partially protruded from the end of the installation section 112 . Since the support block protrudes from the end of the installation section 112, when the support block drives the clamping unit 31 to clamp the optical fiber pigtail 5, the installation section 112 can be located behind the other line interface sections, thereby avoiding interference with other lines. The interference of the interface section can also avoid the interference with the optical fiber line at the rear of the fiber pigtail 5 .

In this embodiment, the above-mentioned clamping unit 31 specifically includes a slider that is guided and slid on the support block. A preferred structure for the slider to guide and slide on the support block is shown in FIG. 2 , FIG. A T-shaped groove 2101 is constructed on the support block, and the angle between the extension direction of the T-shaped groove 2101 and the pulling out direction of the fiber pigtail 5 is set parallel to the opposite surface 211 of the support block, and the T-shaped groove 2101 is narrow. The neck segment is arranged on the opposite surface 211 of the support block; the slider is constructed with a guide block 311 which is adapted to the T-shaped groove 2101 and can guide the slider in the T-shaped groove 2101. The above-mentioned T-shaped groove 2101 is preferably arranged through the length direction of the support block. In order to prevent the slider from coming out of the T-shaped groove 2101, in this embodiment, the support block and the T-shaped groove 2101 A baffle plate 6 is fixed on the sidewalls intersecting with the extending directions of the baffle plate 6 , and the baffle plate 6 can be fixed on the support block by screws not shown in the figure, so as to keep the guide block 311 in the groove 314 .

In this embodiment, as shown in FIG. 2 and FIG. 7 , a mounting hole 2102 is also formed on the support block, and the mounting hole 2102 communicates with the T-shaped groove 2101 . Specifically, the mounting hole 2102 is connected with the T-shaped groove 2101 The mounting hole 2102 has a diameter that is smaller than the width of the wide-diameter section of the T-shaped groove 2101, and is greater than the thickness of the wide-diameter section of the T-shaped groove 2101, so that the following guide block 311 can compress the following first elastic member 7. At the same time, the T-shaped groove 2101 can still guide the guide block 311. The first elastic member 7 is installed in the installation hole 2102, so that the guide block 311 slides in the T-shaped groove 2101 in the direction in which the fiber pigtail 5 is pulled out. When the fiber pigtail 5 is pulled out, the guide block 311 can compress the first elastic member 7. After the fiber pigtail 5 is pulled out, the first elastic member 7 can drive the guide block 311, that is, the slider, to reset due to its own elastic recovery. The first elastic member 7 Cylindrical compression springs may be used.

The above-mentioned slider has an abutting surface 312 parallel to the opposite surface 211 of the support block. The abutting surface 312 is in contact with the opposing surface 211 of the support block, and the abutting surface 312 and the opposing surface 211 constitute a transmission unit between the support block and the slider. Relative to the abutting surface 312 , the clamping surface 313 on the other side of the slider opposite to the abutting surface 312 is arranged at an angle with the abutting surface 312 . Specifically, refer to FIG. 3 , and the clamping surface 313 The surface 313 is arranged so that when the optical fiber pigtail 5 is clamped, the clamping surface 313 is substantially parallel to the longitudinal direction of the optical fiber pigtail 5 .

In order to facilitate the clamping of the optical fiber pigtail 5, in this embodiment, referring to FIG. 1, FIG. 5 and FIG. 6, each clamping surface 313 is configured with a groove 314 that matches the outline of the optical fiber pigtail 5. The clamping of the optical fiber pigtail 5 by the two sliders is specifically the clamping of the optical fiber pigtail 5 by the two grooves 314 .

Since the optical fiber pigtails 5 have different models, for example, the optical fiber pigtails 5 of models FC and ST are cylindrical, and the optical fiber pigtails 5 of types SC and LC are square. For different types of fiber pigtails 5, in this embodiment, the above-mentioned grooves 314 are configured to be square, and when the fiber pigtail 5 is clamped, the bottom walls of the two grooves 314 constitute the pair of fibers. The clamping of the pigtail 5, that is to say, the thickness of the two grooves 314 after they are fully engaged is slightly smaller than the thickness of the thinner fiber pigtail 5, that is, the two grooves 314 can be formed before they are fully engaged. The clamping of the optical fiber pigtail 5 makes it suitable for clamping the optical fiber pigtail 5 of different specifications.

In order to make the fiber pigtail 5 pulling out device also applicable to cylindrical fiber pigtails 5 with models FC and ST, in this embodiment, referring to FIG. 1 , FIG. 5 and FIG. 6 , in the above-mentioned groove 314 The bottom wall is constructed with an arc-shaped groove 315, and the diameter of the arc-shaped groove 315 is configured to be slightly larger than the larger value of the diameter of the cylindrical fiber pigtail 5. The elastic protective layer described above can better constitute the clamping of the cylindrical fiber pigtail 5 .

Specifically, in order to protect the surface of the optical fiber pigtail 5 when clamping the optical fiber pigtail 5, in this embodiment, an elastic protective layer is fixed on the bottom surface and the side surface of the groove 314, which is not shown in the figure. The elastic protective layer can be, for example, a rubber spacer pasted and fixed on the bottom wall and the side wall of the groove 314, so that when the groove 314 clamps the optical fiber pigtail 5, specifically the elastic protective layer is in contact with the optical fiber pigtail 5, This avoids scratching the surface of the optical fiber pigtail 5. At the same time, when the cylindrical optical fiber pigtail 5 is clamped, due to the elastic deformation of the rubber spacer, the arc groove 315 can better fit the optical fiber pigtail 5. Therefore, the cylindrical fiber pigtail 5 is better clamped.

In order to further facilitate the use of the fiber pigtail pulling device, in this embodiment, as shown in FIG. 3 , a second elastic member 8 is further provided between the two manipulation sections 111 , and the second elastic member 8 is used between the two manipulation sections 111 . The segment 111 compresses when it is close, and can drive the two operating segments 111 to reset after the fiber pigtail 5 is pulled out due to its own elastic recovery, which is convenient for the next use. The torsion spring on the operating section 111.

The specific use process of the fiber pigtail pulling device in this embodiment is as follows:

The operator holds the manipulation section 111, so that the two grooves 314 are placed on opposite sides of the fiber pigtail 5; the operator applies an opposite driving force to the two manipulation sections 111 to make the two manipulation sections 111 The groove 314 constitutes the clamping of the optical fiber pigtail 5. The operator continues to exert an opposite driving force on the operating section 111, and the two sliders can move in the direction of pulling out the optical fiber pigtail 5 due to being squeezed. The force analysis diagram is shown in Figure 3. Because the slider receives the component force F in the direction of pulling out the fiber pigtail 5, the fiber pigtail 5 can be pulled out. The two elastic members 8 are driven to reset, and the two sliding blocks are driven to reset by the first elastic member 7 .

To sum up, in the fiber pigtail pulling device of this embodiment, two joysticks 11 hinged in the middle are provided, and a support unit 21 is provided on each joystick 11 , and a clamping portion 3 is provided on each support unit 21 , so that the staff unit can make the two support units 21 close by driving the two joysticks 11 to approach, and the clamping part 3 can first follow the support unit 21 to form the clamping of the fiber pigtail 5, and can be used between the two When the supporting units 21 continue to approach, the optical fiber pigtail 5 is driven by the clamping unit 31, so that the optical fiber pigtail 5 is pulled out from the equipment 4. First, the two joysticks 11 control the supporting units 21 to approach by a lever mechanism. In addition, the pulling out operation of the fiber pigtail 5 is also realized by driving the two joysticks 11 to approach, which is more convenient to operate, and at the same time, it will not cause the operator's arm to move suddenly, which can reduce the potential safety hazard. .
