Energy-saving device of communication switch

The invention discloses an energy-saving device of a communication switch. Comprising a damp-proof bottom plate fixedly connected to the lower surface of a clamping frame, a detachable transverse plate clamped to one side of a rotating ring, an extension plate fixedly connected to the bottom of the side face of a bottom frame, an expansion cover fixedly connected to the bottom end of a metal hose and capable of expanding the dust collection area, and a ventilation fan fixedly installed on the upper surface of the transverse plate and capable of conducting ventilation and heat dissipation. The upper surface of the extension plate is connected with a detachable fixing column through a bolt. According to the energy-saving device of the communication switch, through the arrangement of a ventilation fan, a telescopic column and a rubber pad, in order to improve the energy-saving efficiency of the switch, a clamping frame, a switch box and a bottom plate can be installed by a constructor, the device is relatively c
