To solve the falling off caused by the external force dragging traditional plugs and sockets and prevent the occurrence of electrical fire, this product integrates telescopic rod, sucker, plug and socket. It adopts the concept that telescopic rod can extend to the position users want to solve the inconvenience caused by fixed socket. This design enables easy disassembly and assembly. The sucker can be firmly fixed by contacting two suckers and expel the air within, greatly reducing the falling off caused by the external force dragging the plug and socket. Also, it can reduce the invasion of dust and moist to prevent the occurrence of electrical fire. This simple design not only has high portability but also assures the safety for using electric appliance.
