[0023] The telescopic spring rod structure 52 includes a T-shaped sub-rod 521 passing through the side wall of the protective plate 51, a mother rod 522 for storing the T-shaped sub-rod 521, a limit spring 523 located at the bottom surface of the thick column end of the T-shaped sub-rod 521, and a mother rod cover 524 for closing the open end of the mother rod 522.
