One end of the lower clip portion 341 is connected to the upper clip portion 343, and the other end thereof forms an outer inclined section 345 inclined forward along the front-rear direction B. The upper clip portion 343 has one end connected to the lower clip portion 341 and the other end forming an inner hook 346 extending rearward in the front-rear direction B to have a hook shape. The outer angled sections 345 face the inner hook sections 346 and are spaced apart from one another to define the slots 344.

Referring to fig. 2, fig. 3 and fig. 4, the present embodiment can be applied to a Connector corresponding to SC (Subscriber Connector/Standard Connector) specification and an adapter corresponding to MPO (Multi-fiber Push On) specification, but is not limited thereto. The outward protruding portion 253 of each side guide 25 can be deformed to contract inward along the horizontal direction a when pushed by the force along the front-back direction B by its external shape design, so that the outward protruding portion 253 is no longer locked (or only a small portion is locked) in the corresponding limiting groove 242, this design allows the user to pull the partition plate 31 of any one of the extracting units 3 along the front-back direction B (the front blocking piece 214 needs to be removed first) to extract the whole extracting unit 3 forward, when each outward protruding portion 253 is aligned with the next limiting groove 242, the outward protruding portion 253 will be restored by elasticity and locked in the limiting groove 242 again, so as to achieve the effect of limiting, the user can continue to move the extracting unit 3 outward by continuing to exert the force, forming a sectional extracting design, which can avoid opening the extracting unit 3 and arranging the lines and components thereon, the drawing unit 3 is moved back to the original position or the walking position due to the light touch, and the configuration convenience is improved.

Referring to fig. 2, 3, 5 and 7, in addition to the whole drawing unit 3, the user can take out the single setting seat 33 of each drawing unit 3 along the front-back direction B by bending the front end of the receiving portion 322 of the corresponding inner rail 32, and moving the front protrusion 323 out of the corresponding positioning groove 336 through deformation, so that the setting seat 33 can be drawn out forward as shown in fig. 7, at this time, the inner inclined surface 337 of the rear limiting section 334 pushes the inclined guide surface 328 of the rear protrusion 323, and the pushing force generates a component force along the horizontal direction a due to the inclined surface, so that the rear end of the receiving portion 322 is bent outward, thereby not limiting the forward drawing of the setting seat 33. When the installation seat 33 is to be installed, the installation seat 33 can be installed backward between the two corresponding inner rails 32 along the front-back direction B, and at this time, the outer inclined surface 338 of the rear limiting section 334 pushes the inclined guide surface 328 of the front protrusion 323, so that the pushing force generates a component force along the horizontal direction a due to the inclined surface, and the front end of the receiving portion 322 is bent outward, so that the installation seat 33 can be installed backward. Referring to fig. 2, 3 and 8, since the two ends of the receiving portion 322, the protruding portion 323 and the limiting section 334 are designed to be symmetrical front and back, a user can also apply force to bend the back end of the receiving portion 322 to pull the setting seat 33 back as shown in fig. 8, and by means of the design that can be pulled back and forth, convenience in pulling can be increased, and flexibility in configuring the optical fiber distribution frame 1 can be increased. It should be noted that, when the protruding portions 323 are respectively engaged in the positioning grooves 336 of the setting seat 33, the blocking surface 339 of the middle portion 335 abuts against the positioning surface 327 of the protruding portions 323, and since the blocking surface 339 and the positioning surface 327 are both flat surfaces, even if a force is applied to the setting seat 33, a component force is not generated along the horizontal direction a, so that both ends of the receiving portion 322 are not deformed, thereby achieving the effect of positioning the setting seat 33.

Referring to fig. 2, 6 and 9, in the present embodiment, the opening degree of the slot 344 of each wire organizer 34 is slightly smaller than the outer diameter of the optical fiber line, and the hook-shaped shape of the inner hook section 346 is added, so that the optical fiber line bundled in the wire accommodating area 342 is not removed from the slot 344, and since the wire organizer 34 is flexible and elastic, a user can push the outer inclined section 345 from outside to inside, and a force applied to the outer inclined section 345 generates a component force directed to the inner hook section 346, so that the upper clamping portion 343 is bent and deformed upward and outward, and the opening degree of the slot 344 is increased, so that the optical fiber line can be quickly placed into the wire accommodating area 342 from outside. On the contrary, when the optical fiber line is to be removed from the line accommodating region 342, the upper clamping portion 343 is directly pulled upward, so that the upper clamping portion 343 is away from the lower clamping portion 341 to increase the opening degree of the slot 344, so as to remove the optical fiber line from the slot 344. If the optical fiber line is further prevented from moving out, the lower clamping portion 341 and the upper clamping portion 343 may be pressed to buckle the outer inclined section 345 and the inner hook section 346 as shown in fig. 9, so as to achieve the effect of closing the slot 344. Of course, the user can reopen the slot 344 by separating the outer angled section 345 and the inner hooked section 346.

In summary, the present invention utilizes the installation seats 33 and the inner guide rails 32 to allow each installation seat 33 to be drawn out or placed in forward or backward respectively, thereby forming a bidirectional drawer design, improving the overall configuration flexibility and facilitating assembly and disassembly; in addition, the wire arranging device 34 can simply bundle the optical fiber circuits into a bundle and quickly take out any optical fiber circuit, so that the effect of quickly arranging the optical fiber circuits can be achieved, the optical fiber circuits can be limited on the optical fiber distribution frame, the convenience of arranging the optical fiber circuits is improved, and the purpose of the utility model can be really achieved.
