Safe 5G Internet of Things communication device

The invention discloses a safe 5G Internet of Things communication device, which comprises a main body assembly, a fixing assembly and a buffer assembly, and is characterized in that the main body assembly comprises a shell, a first plate body, a damping pad, a connecting rod, a signal transceiver, a supporting rod and a fan; the fixing assembly comprises a first threaded pipe, a conical groove, a second threaded pipe, a conical rubber pad and a wire; the buffer assembly comprises a second plate body, a spring, a sleeve and a through hole. When the wire is touched by mistake by external force, the wire pulls the second threaded pipe and the first threaded pipe, the first threaded pipe and the sleeve are fixed, the sleeve pulls the second plate body, and the second plate body extrudes the spring; at the moment, when the wire is in butt joint with an electronic element, a small redundant section of the wire is reserved in the shell, so that the external force generated by mistakenly touching the wire can be con
