ABSTRACT:
A telescopic display stand includes a base and a fixed tube secured on the base. A first telescopic tube and a second telescopic tube are in turn telescopically received in the fixed tube. A gear box is mounted in the first telescopic tube, and a plug is mounted in the second telescopic tube. A first threaded rod has a bottom end rotatably received in the fixed tube and threadingly extends through the gear box. A second threaded rod has a bottom end rotatably mounted in the gear box and threadingly extends through the plug. A driving unit is mounted on the gear box for driving gears in the gear box. An effigy sheath is mountable over the fixed tube and telescopic tubes. Whereby, the display stand can be automatically erected and retracted.
