[0031] The present invention provides a fiber pulling device 100 specifically for an LC type optical fiber coupler.

[0033] In this embodiment, the upper clamping plate 21, the lower clamping plate 22, the fixing pin 23 and the pressing member 24 are all made of stainless steel, and the electronic box 10 is made of plastic material and is a rectangular hollow box, which can reduce the weight as much as possible without affecting the use, so as to facilitate the operator to carry;

[0034] One end of the upper clamping plate 21 and the lower clamping plate 22 are planes, which are bent and extended outward from the planes, and the distance between the two gradually increases from the fitting position. The fixing pin 23 is installed at a position where the distance between the two is larger. When the pressing member 24 is pressed down, the upper clamping plate 21 is pressed down, and the end of the upper clamping plate 21 can be against the end of the lower clamping plate 22, so that the optical fiber coupler can be firmly clamped, which solves the problem of optical fiber coupler slipping or mis-pulling caused by traditional fiber pulling tools during operation, and improves the accuracy and safety of the operation.

[0035] In one embodiment of the present invention, a sliding groove 13 is opened in the electronic box 10, and the upper clamping plate 21 and the lower clamping plate 22 are installed in the sliding groove 13 and can move along the sliding groove 13 to change the length of the upper clamping plate 21 and the lower clamping plate 22 exposed outside the electronic box 10; a positioning member 17 is provided on the electronic box 10, and a plurality of positioning holes 212 are respectively provided on the upper clamping plate 21 and the lower clamping plate 22. When the upper clamping plate 21 and the lower clamping plate 22 are attached together, the positioning holes 212 of the two are aligned, and the positioning member 17 is stuck in one of the positioning holes 212.

[0036] In this embodiment, the electronic box 10 includes a cover plate 12 and a box body 11, and the cover plate 12 and the box body 11 are removable.

In data centers and communication rooms, due to the high density of optical fiber wiring, the environment is usually relatively narrow. The slender design of the upper clamping plate 21 and the lower clamping plate 22 solves the problem of difficulty in operating the optical fiber coupler in a limited space, thereby improving the applicability and flexibility of the device.

[0037] In one embodiment of the present invention, the upper clamping plate 21 is provided with a first through hole 211, and the lower clamping plate 22 is provided with a second through hole 221, the first through hole 211 is aligned with the second through hole 221, and the fixing pin 23 passes through the first through hole 211 and the second through hole 221 and is connected to the pressing member 24; a notch 231 is provided at the top of the fixing pin 23, and a straight column 241 is provided on the pressing member 24, and the straight column 241 is clamped at the notch 231 to connect and cooperate with the fixing pin 23.

By utilizing the principle of leverage, the optical fiber coupler can be firmly clamped with less force, thereby reducing the operating difficulty and fatigue of the operation and maintenance personnel.

[0040] In this embodiment, the second groove 223 is wider than the first groove 213 and is used to fix the optical fiber coupler to avoid the optical fiber coupler from being offset or detached during the clamping process. The boss 214 is used to press the optical fiber coupler. When the upper clamping plate 21 is pressed down, the boss 214 is also pressed down to press against the optical fiber coupler to improve the clamping stability.
