[0001] The invention relates to the technical field of cable auxiliary equipment, and in particular to an anti-fracture through-hole drilling tool based on optical fiber transmission. Background Art

[0002] In recent years, with the continuous progress and development of society, people's living standards are also constantly improving. As a result, the communication devices used in some building construction have been replaced by optical cable transmission instead of ordinary cables. Some home networks also generally use optical fiber to enter the home directly. Some users who add or change to using optical fiber later need to complete the optical fiber entry by threading.

[0015] Beneficial Effects

[0016] The auxiliary threader according to each embodiment of the present invention is compared with a traditional threader in that the fiber optic installation head is snapped onto the protection component, and the protection component is a mutually interlocking structure, so that the protection component has a protective function for the fiber optic installation head, and installation components are provided at the upper and lower ends of the protection component, and the installation component can connect the optical fiber line, and after the optical fiber line is stably connected to the installation component, the protective component at the outer end of the installation component protects the optical fiber line, so that the device can not only transport the fiber optic installation head, but also directly connect the optical fiber line for transmission, and the outermost end of the device is sleeved with an outer wall component, and the outer wall component with a guide component helps the device as a whole to better realize the threading operation.

[0017] In addition, the guide strips are arranged in a circular array on the outer wall of the outer wall tube, so that the overall outer wall tube has a certain toughness increased by the guide strips, avoiding the outer wall tube from bending at too large an angle. Because there will inevitably be a barrier layer at the internal interface position of the pipeline, the left side of the outer wall tube is set as an inclined chamfer structure, so that the outer wall component has a better carrying device to pass through as a whole, and the inner wall on the guide strip is opened into a spherical structure, so that the installation port can better install the ball. The ball with a spherical structure has the effect of smoother rotation, and the ball set as a protruding structure has the effect of better allowing the outer wall component to slide in the pipeline, thereby achieving a better threading effect.

[0018] In addition, the protective block, which is set to a vertically symmetrical structure, has a stable snap-fitting effect on the optical fiber installation head, so that the protective block can fix and protect the optical fiber installation head. A connector is set on the left side of the protective block to realize the connection between the connector and the external component. In order to ensure a certain sealing of the optical fiber installation head after the protective block is snapped together, contact strips are set at the mutual contact positions of the protective blocks, which further increases the snap-fitting and sealing effect of the contact strip on the protective block.

[0019] In addition, the installation groove is directly set on the right side of the protection component, so that the protection component has the function of driving the installation component to thread the wires. The outer end surface of the installation groove is grooved, which has the function of facilitating the optical fiber line to be directly inserted into the installation groove from the outside. The installation groove is provided with a positioning hole, which has the function of allowing the metal wire in the optical fiber line to be fixedly connected through the positioning hole, and the optical fiber line can be directly fixed and then guided for threading. The protective plate is directly set to be clamped on the outer wall of the installation groove, so that the protective plate can protect the optical fiber line placed in the installation groove.

[0020] In addition, the sliding block is slidably installed on the sliding bar, so that the sliding block can contact with the auxiliary component, thereby realizing the limiting and fixing effect of the subsequent sliding component on the auxiliary component. The installation of the adjusting block is to add a spring, so that the adjusting block is a structure that always protrudes outward, so that the adjusting block can better contact with the sliding bar to realize the position fixing effect of the adjusting block on the sliding block. The two groups of adjusting blocks are pressed together to realize the sliding effect of the sliding block, thereby completing the adjustment effect of the adjusting component on the sliding component.

[0021] In addition, because the device as a whole fixes the optical fiber installation head, when threading the optical fiber installation head through the device, it is inevitable to pass through the bending position of the pipe, so the auxiliary block fixed on the optical fiber installation head is provided with multiple groups of spacing grooves to allow the auxiliary block to have a certain anti-pulling effect, thereby allowing the auxiliary block to play a protective effect on the optical fiber installation head.
