Its technical solution includes: a long glass fiber reinforced plastic base frame, a top frame and a threaded lifting rod. Two sets of positioning rods are installed on both sides of the top of the long glass fiber reinforced plastic base frame, and a threaded sleeve is installed on the top of the long glass fiber reinforced plastic base frame. The inside of the long glass fiber reinforced plastic base frame is movably installed with a threaded lifting rod through a threaded sleeve. A bearing is installed on the top of the threaded lifting rod, and the top of the bearing is installed on the top of the top frame. The utility model has a threaded lifting rod movably installed inside the long glass fiber reinforced plastic base frame.
