Signal detection device for first-aid repair of communication engineering

The utility model relates to the technical field of maintenance tools, in particular to a signal detection device for communication engineering first-aid repair, which comprises a detection meter and a portable box, a slot for inserting the detection meter is arranged above the portable box, the upper end and the lower end of the back side of the detection meter are connected with a plurality of magnetic strips, and the middle part of the back side is fixedly connected with a plurality of friction strips which are arranged in parallel. The end face of the friction strip is 2-4 mm higher than the magnetic strip. The detection meter can be attracted and fixed on the box door of the communication box through the magnetic strip, the friction strip abuts against the surface of the box door of the communication box, friction force is generated, the detection meter is prevented from sliding down due to vibration when attracted, the detection meter is fixed stably, and use is convenient. 本实用新型涉及检修工具技术领域，具体涉及一种通信工程抢修的
