Electric power Internet of Things fault detection device and detection terminal

The invention discloses a power internet of things fault detection device, which comprises a detection pen and a terminal body, the detection pen is electrically connected with the terminal body through a transmission line, the terminal body is provided with an electronic display screen, and a protection assembly is arranged above the electronic display screen. According to the invention, during detection in an environment where operation is inconvenient, a protective cover can be opened, a second driving motor drives a double-thread screw to rotate, the double-thread screw drives two nut blocks to move relatively, so that a supporting arm moves, the supporting arm drives an adjusting mechanism to move upwards, the adjusting mechanism drives an electronic display screen to move out of a reserved cavity, and a first driving motor drives a driving arm to rotate; the driving arm drives the limiting pin to slide in the through groove, the long arm is driven to rotate around the fixed shaft through the through gro
