The column that connects said upper and lower cover boards, U-shape bracket between two columns, said front cover board and said back cover board hold said main bracket therein, and the connecting piece is for connection purpose.
- Said upper cover board of basal body is one integrated board, which is provided with one opening on the position opposite to said notch.
- Said upper cover board of basal body is the separate board, and lies in two side of said notch respectively.
- Said lower cover board of basal body is provided with opening.
- Said basal body further includes end cover fixed onto said main bracket.
- Two sidewalls of said notch on said basal that hold said display consist of said front cover board, said U-shape bracket and said back cover board. Two walls of said U-shape bracket are provided with half-axle holes, and the part of said front cover board that adjoins said two sides of said U-shape bracket is also provided with half-axle holes, and these half axle-holes together form the center axle holes that match said center axles of said display.
- Said center axle on one end of said display is positioning axle, on which there is elastic positioning piece. The inside wall of axle hole that corresponds to positioning axle is provided with 2 to 4 positioning slots, which is so placed that said display can just positioned horizontally or vertically when said elastic positioning piece enters said positioning slot.
- Said positioning axle of said display is hollow plastic axle, whose wall is provided with U-shape slot of axial direction. What is encircled by said U-shape slot is said elastic positioning piece, whose end is provided with protruding deck that matches said positioning slot.
- Said center axle on the other end of said display is position-restriction axle, which is provided with protruding deck. The inside wall of the axle hole that corresponds to said position-restriction axle is provided with obstacle steps that can limit the rotated angle of position-restriction axle.
