Problems solved by technology

[0003] In the prior art, the patent with the publication number CN213779452U discloses a device for optical time domain reflectometer optical fiber testing, including a storage box, the inner walls of both sides of the storage box are provided with pulley grooves, and the two pulleys The inner walls on both sides of the groove are rollingly connected with pulleys, and the sides of the two pulleys close to each other are fixedly connected with the same optical time domain reflectometer. The optical time domain reflectometer forms the brake component of the brake. One side of the storage box is provided with a groove, and the inner walls of both sides of the groove are provided with chutes, and the two chutes are slidably connected. There is a slider, and the structure of the above-mentioned patent is simple. The optical time domain reflectometer can be stored in the storage box through the pulley groove and the pulley, and the top of the locking block is staggered from the card slot by rotating the block, so that the optical time domain reflectometer can be formed. Move the OTDR to prevent the OTDR from the storage box, and flip the OTDR to rotate the OTDR into the groove, and brake the OTDR through the slider. The storage box can Effectively support the optical time domain reflectometer to prevent the optical time domain reflectometer from tipping over during the detection process, resulting in damage to the optical time domain reflectometer. However, the connector of the optical time domain reflectometer is exposed to the air when it is not in use , Dust accumulation is prone to occur at the joint, so when the optical time domain reflectometer is used to detect the communication fault point of the cable again, the dust accumulated inside the joint is likely to interfere with the detection of the cable. At the same time, the cable is connected to the joint When performing detection and positioning, the connection between the cable and the connector is prone to large bends, which interferes with the positioning detection of the optical time domain reflectometer, reduces the accuracy of the positioning detection, and is not conducive to the optical time domain reflectometer for the cable. Positioning detection is not convenient for the application of optical time domain reflectometer in the field of 5G communication technology
